Common Oracle SQL Tuning Errors - Lesson 1 Validate and tweak the Design for SQL Performance
 
07:44
Lesson 1: Before tuning SQL it is important to look at the data design. For example, is the design under or over-normalized? Are the correct data types used? Are the keys indexed? What constraints are declared? All of these and more have an impact on SQL response time.

Prevent sql injection with dynamic sql

In Part 140, we have implemented "Search Page" using dynamic SQL. Since we have used parameters to build our dynamic SQL statements, it is not prone to SQL Injection attack. This is an example of good dynamic SQL implementation. I have seen lot of software developers, not just the beginners but even experienced developers, buidling their dynamic sql queries by concatenating strings instead of using parameters without realizing that they are opening the doors for SQL Injection. Please check my blog at the following link for code used in the demo. http://csharp-video-tutorials.blogspot.com/2017/04/prevent-sql-injection-with-dynamic-sql.html Since we are concatenating the user input values to build the dynamic sql statement, the end user can very easily inject sql. Imagine, what happens for example, if the user enters the following in the "Firstname" textbox. ' Drop database SalesDB -- With the above SQL injected into the "Firstname" textbox, if you click the "Search" button, the following is the query which is sent to SQL server. This will drop the SalesDB. Select * from Employees where 1 = 1 AND FirstName = '' Drop database SalesDB --' On the other hand, if you use parameters to build your dynamic SQL statements, SQL Injection is not an issue. The following input in the "Firstname" textbox, would not drop the SalesDB database. ' Drop database SalesDB -- The text the user has provided in the "Firstname" textbox is treated as the value for @Firstname parameter. The following is the query that is generated and executed. exec sp_executesql N'Select * from Employees where 1 = 1 AND [email protected]',N'@FirstName nvarchar(26)',@FirstName=N''' Drop database SalesDB --' We don't have this problem of sql injection if we are using stored procedures. "SearchPageWithoutDynamicSQL.aspx" is using the stored procedure "spSearchEmployees" instead of dynamic SQL. The same input in the "Firstname" texbox on this page, would generate the following. Notice, whatever text we typed in the "Firstname" textbox is treated as the value for @FirstName parameter. exec spSearchEmployees @FirstName=N''' Drop database SalesDB --' An important point to keep in mind here is that if you have dynamic SQL in your stored procedure, and you are concatenating strings in that stored procedure to build your dynamic sql statements instead of using parameters, it is still prone to SQL injection. If this is not clear at the moment don't worry, we will discuss an example of this in out next video. So in summary, while dynamic sql provides great flexibility when implementing complicated logic with lot of permutations and combinations, if not properly implemented it may open doors for sql injection. Always use parameters to build dynamic sql statements, instead of concatenating user input values. Another benefit of using parameters to build dynamic sql statements is that it allows cached query plans to be reused, which greatly increases the performance. We will discuss an example of this in our upcoming videos.

R tutorial: connecting to a database
 
03:38
Learn more about connecting to databases with R: https://www.datacamp.com/courses/importing-data-in-r-part-2 Welcome to part two of importing data in R! The previous course dealt with accessing data stored in flat files or excel files. In a professional setting, you'll also encounter data stored in relational databases. In this video, I'll briefly talk about what a relational database is and then I'll explain how you can connect to it. In the next video, I'll explain how you can import data from it! So, what's a relational database? There's no better way to show this than with an example. Take this database, called company. It contains three tables, employees, products and sales. Like a flat file, information is displayed in a table format. The employees table has 5 records and three fields, namely id, name and started_at. The id here serves as a unique key for each row or record. Next, the products table contains the details on four products. We're dealing with data from a telecom company that's selling both with and without a contract. Also here, each product has an identifier. Finally, there's the sales table. It lists what products were sold by who, when and for what price. Notice here that the ids in employee_id and product_id correspond to the ids that you can find in the employees and products table respectively. The third sale for example, was done by the employee with id 6, so Julie. She sold the product with id 9, so the Biz Unlimited contract. These relations make this database very powerful. You only store all necessary information once in nicely separated tables, but can connect the dots between different records to model what's happening. How the data in a relational database is stored and shuffled around when you make adaptations, depends on the so-called database management system, or DBMS you're using. Open-source implementations such as MySQL, postgreSQL and SQLite are very popular, but there are also proprietary implementations such as Oracle Database and Microsoft SQL server. Practically all of these implementations use SQL, or sequel, as the language for querying and maintaining the database. SQL stands for Structured Query Language. Depending on the type of database you want to connect to, you'll have to use different packages. Suppose the company database I introduced before is a MySQL database. This means you'll need the RMySQL package. For postgreSQL you'll need RpostgreSQL, for Oracle, you'll use ROracle and so on. How you interact with the database, so which R functions you use to access and manipulate the database, is specified in another R package called DBI. In more technical terms, DBI is an interface, and RMySQL is the implementation. Let's install the RMySQL package, which automatically installs the DBI package as well. Loading only the DBI package will be enough to get started. The first step is creating a connection to the remote MySQL database. You do this with dbConnect(), as follows. The first argument specifies the driver that you will use to connect to the MySQL database. It sure looks a bit strange, but the MySQL() function from the RMySQL package simply constructs a driver for us that dbConnect can use. Next, you have to specify the database name, where the database is hosted, through which port you want to connect, and finally the credentials to authenticate yourself. This is an actual database that we're hosting, so you can try these commands yourself! The result of the dbConnect call, con, is a DBI connection object. You'll need to pass this object to whatever function you're using to interact with the database. Before we do that, let's get familiar with this connection object in the exercises!

Best Way to Write Basic SQL Queries
 
13:33
SQL Server Query writing strategies is something I have yet to find in any book. When enthusiastic SQL students do this, they experience a revelation. The number of errors drops significantly and the speed at writing complex queries increases immediately. Knowing how to narrow down what we are looking for amongst a vast list of choices helps immensely. Grabbing the right tables first and then the fields second is akin to grabbing the right menu before ordering an item from it. In fact, one student named Tim took this back to his team of SQL developers and they immediately implemented this process. We are all used to following steps. Most of the time, actions are sequential from top to bottom or left to right. Other times we complete things in phases. The two phases we are going to use in this exercise apply to joining tables. This is easy to implement as we only need remember to organize first and clean up second. When visiting a new restaurant, we will ask to see the menu, because we want to see all they have to offer. The odds are that we might be interested in half of the items, but only need a few dishes for our group at the table. Looking at the menu is like starting a query with a ‘SELECT *’ statement. Once we have looked at all the fields, we narrow our choice(s) to only the items we want at the time. Sometimes restaurants have multiple menus. My favorite restaurant has a kids’ menu, an adult menu, a gluten-free menu and a drink menu. These menus were each gathered at our table. Ultimately, in my head, a selection was narrowed to what was needed. Phase I: Organize. When building a new query from many tables, we often find ourselves wondering, “Where do I start?” First, lay the steps out by identifying which tables contain the essential data. Second, get all the table joins working with a basic ‘SELECT *’ statement. Third, add any basic filtering criteria. Phase II: Itemize. Once all joins and criteria, such as SELECT, FROM and WHERE are working, we are ready for Phase II. This entails going back and changing our ‘SELECT *’ to an itemized SELECT field list as the final step. Let’s explore how this two-phase process of Organize and then Itemize can be a big time-saver. We are going to use one of the challenges from the last lab. In Lab 3.2 (Outer Joins), Skill Check 2, we needed to get four fields from two different tables. If we were to list all four desired fields and test one table at time, we will get an error as seen on the right side of the figure below. In the figure below we write a SELECT statement and part of the FROM clause. When completed, the FROM clause will have two tables, but for now we just want to get the Location table working. By using the ‘SELECT *’ strategy, we remove any possible errors from line 1. From there, we can focus on the more complicated logic used for joining tables together. We can add tables one at a time until everything is working. This is the Organize phase. NOTE: SELECT * never results in an Error message stating “invalid column name”, however; a SELECT list with itemized field(s) can have this error. After our query is organized and working, we can go back and itemize the SELECT field list to display only the fields that are necessary. This is done during Phase II (Itemize). The steps for this system are broken down as follows: Since SELECT is always the first statement in a query, it’s natural to want to write the field names before writing the FROM clause. However; we can save time and trouble by using the ‘*’ until the entire query is working properly. When this is complete, it is very easy to itemize the field list, with the confidence of knowing it will not cause any problems. Exercise: Simple membership for a club: Table1 (id_Member,name_Member, email_member, title, age, company) Table2 (id_Club,club_name, club_Location, address) Table3 (id_club, id_member,membership_date) Q1: Show all member names, email, age, and company from Table1 Q2: Show all club name, location, and address data Q3: Show member name, club name, club location (hint: Use joins and all 3 tables) You can find all other classes related to this video here: http://www.joes2pros.com/joes2pros/Course/Introduction_To_Microsoft_SQL_Server Enroll Today & Get the First Month for only $1!

Debugging sql server stored procedures
 
15:11
debugging in ssms debugging t-sql code t sql debug stored procedure sql server management studio debug stored procedure how to debug t sql debug in sql server management studio In this video we will discuss how to debug stored procedures in SQL Server. Setting up the Debugger in SSMS : If you have connected to SQL Server using (local) or . (period), and when you start the debugger you will get the following error Unable to start T-SQL Debugging. Could not connect to computer. To fix this error, use the computer name to connect to the SQL Server instead of using (local) or . For the examples in this video we will be using the following stored procedure. Create procedure spPrintEvenNumbers @Target int as Begin Declare @StartNumber int Set @StartNumber = 1 while(@StartNumber [ @Target) Begin If(@StartNumber%2 = 0) Begin Print @StartNumber End Set @StartNumber = @StartNumber + 1 End Print 'Finished printing even numbers till ' + RTRIM(@Target) End Connect to SQL Server using your computer name, and then execute the above code to create the stored procedure. At this point, open a New Query window. Copy and paste the following T-SQL code to execute the stored procedure. DECLARE @TargetNumber INT SET @TargetNumber = 10 EXECUTE spPrintEvenNumbers @TargetNumber Print 'Done' Starting the Debugger in SSMS : There are 2 ways to start the debugger 1. In SSMS, click on the Debug Menu and select Start Debugging 2. Use the keyboard shortcut ALT + F5 At this point you should have the debugger running. The line that is about to be executed is marked with an yellow arrow Step Over, Step into and Step Out in SSMS : You can find the keyboard shortcuts in the Debug menu in SSMS. Let us understand what Step Over, Step into and Step Out does when debugging the following piece of code 1. There is no difference when you STEP INTO (F11) or STEP OVER (F10) the code on LINE 2 2. On LINE 3, we are calling a Stored Procedure. On this statement if we press F10 (STEP OVER), it won't give us the opportunity to debug the stored procedure code. To be able to debug the stored procedure code you will have to STEP INTO it by pressing F11. 3. If the debugger is in the stored procedure, and you don't want to debug line by line with in that stored procedure, you can STEP OUT of it by pressing SHIFT + F11. When you do this, the debugger completes the execution of the stored procedure and waits on the next line in the main query, i.e on LINE 4 in this example. To stop debugging : There are 2 ways to stop debugging 1. In SSMS, click on the Debug Menu and select Stop Debugging 2. Use the keyboard shortcut SHIFT + F5 Show Next Statement shows the next statement that the debugger is about to execute. Run to Cursor command executes all the statements in a batch up to the current cursor position Locals Window in SSMS : Displays the current values of variables and parameters If you cannot see the locals window or if you have closed it and if you want to open it, you can do so using the following menu option. Locals window is only available if you are in DEBUG mode. Watch Window in SSMS : Just like Locals window, Watch window is used to watch the values of variables. You can add and remove variables from the watch window. To add a variable to the Watch Window, right click on the variable and select "Add Watch" option from the context menu. Call Stack Window in SSMS : Allows you to navigate up and down the call stack to see what values your application is storing at different levels. It's an invaluable tool for determining why your code is doing what it's doing. Immediate Window in SSMS : Very helpful during debugging to evaluate expressions, and print variable values. To clear immediate window type ]cls and press enter. Breakpoints in SSMS : There are 2 ways to set a breakpoint in SSMS. 1. By clicking on the grey margin on the left hand side in SSMS (to remove click again) 2. By pressing F9 (to remove press F9 again) Enable, Disable or Delete all breakpoints : There are 2 ways to Enable, Disable or Delete all breakpoints 1. From the Debug menu 2. From the Breakpoints window. To view Breakpoints window select Debug =] Windows =] Breakpoints or use the keyboard shortcut ALT + CTRL + B Conditional Breakpoint : Conditional Breakpoints are hit only when the specified condition is met. These are extremely useful when you have some kind of a loop and you want to break, only when the loop variable has a specific value (For example loop varible = 100). How to set a conditional break point in SSMS : 1. Right click on the Breakpoint and select Condition from the context menu 2. In the Breakpoint window specify the condition Text version of the video http://csharp-video-tutorials.blogspot.com/2015/09/debugging-sql-server-stored-procedures.html Slides http://csharp-video-tutorials.blogspot.com/2015/09/debugging-sql-server-stored-procedures_28.html

We can also say that SQL tables are kind of data structure which are used by database for efficient storage of data. To create a table in our database we use SQL CREATE TABLE command. SQL CREATE TABLE is a type of DATA DEFINITION LANGUAGE also known as DDL. To Create a table in your schema you will require CREATE TABLE system privilege. In our future videos we will see what are system and object privileges and how to grant them to a user. Today for this video we will be using Sample schema HR which already has all the necessary privileges. Ohk Let's see the syntax. CREATE TABLE table name ( column name1 Data-Type(size), column name2 Data-Type(size), ..... ); CREATE TABLE is an oracle reserved word or say an Oracle key word whereas There are 3 different ways of creating a table in Oracle database. Creating a table using Command Line Interface (CLI) in Oracle database For demonstrating how to create table in oracle database using CLI, I'll be using Command prompt. Thats how we create table using command prompt. you can check your table structure by DESCRIBE command for that just write DESC and your table name. Like this Another way of creating a table is by using Graphic user interface (GUI) in Oracle database To demonstrate how to create table using GUI we will use SQL developer. Lets open our SQL developer I am connected to HR schema if you do not know how to create a connection to database using SQL developer please watch my oracle database tutorial 4 that explains database connectivity using SQL developer and command prompt. Link for this video is in the description below. So lets create a table. Creating a table using SQL developer is very easy we do not have to fire any query here. Let's start First of all right click on your connection in which you want to create a table and choose schema browser. This will open a separate schema browser pane or you can expend your connection by clicking this + sign and then right click on table and choose New Table. However I prefer working with schema browser so let's skip to schema browser pane here from the first drop-down list you can choose connection name and in the second drop down list you can choose what database objects you want to work with we want to create a table thus I'll choose table and then click this arrow here and choose option for new table Ok we have created a table wizard first of all give a unique name to your table and add some column as well. For this, click the green plus button. Now we already have a column so give it some name. Also choose a datatype from the list and specify any size you can check this not null column if in case you want to make this a mandatory column you can also specify default value and constraint If you want to make this column a primary key you can click here In my future video i'll show you what are these constraints and different ways of applying them on a column in a table. for this video we will concentrate on create table only so when you are done with all your columns click ok Thats your table You can double click on your table here and can see its structure. Thats it

Operational Validation of SQL Server at scale with PowerShell and Jenkins
 
57:04
Presented March 1, 2017 by Cody Konior. Are you accountable for databases or database servers? Do you fix problems only to see them pop up again months or years later in slightly different scenarios? Have you been called at 2am and asked to “health check” hundreds of servers for an issue that nobody in the world has ever documented before and wished there was an easy mode to do that or even avoid the problem in the first place? If so then Operational Validation can help you. In this session you’re going to get: A mindset on how to handle your day to day duties in a way that keeps you efficient, honest to yourself and to others, while covering your posterior. Free tools to fix things and make sure they stay fixed over time. Really free. As in you couldn’t pay for them even if you wanted to. If you work with one instance you’re going to learn how to manage five hundred instances. And if you work with five hundred instances you’re going to learn how to have fun doing it. We’re going to learn: Jenkins, a cool web application you can install on your workstation to provide orchestration and reports. How to integrate PowerShell with Jenkins and multi-thread efficiently in the background with PoshRSJob using ready-to-go templates so you don’t need to worry about how it works. Then we’re going to write some tests. They’re not going to be beautiful tests. We’re going to be testing some of the scummiest, most crapulent edge cases SQL Server has to offer. Please bring tissues because there will be tears. If you’ve ever said, “I don’t know what to test”, I’ll make you regret it. I’ll also discuss a few other PowerShell modules like CimSession and DbData and why you might want to use them for reliable and scalable tests. By the end of the session you should be bouncing off the wall and reconsidering your life. I want you to start screaming about Operational Validation from the rooftops, and have the tools and know-how to quickly start on your own.

PLS-4: PL/SQL Variables

View & manage your progress/pace 3. In-class projects and code reviews 4. Personal guidance from your Mentors ---------------------------------------------------------------------------------------- A variable is nothing but a name given to a storage area that our programs can manipulate. Each variable in PL/SQL has a specific data type, which determines the size and layout of the variable's memory; the range of values that can be stored within that memory and the set of operations that can be applied to the variable. The name of a PL/SQL variable consists of a letter optionally followed by more letters, numerals, dollar signs, underscores, and number signs and should not exceed 30 characters. By default, variable names are not case-sensitive. You cannot use a reserved PL/SQL keyword as a variable name. PL/SQL programming language allows to define various types of variables, which we will cover in subsequent chapters like date time data types, records, collections, etc. For this chapter, let us study only basic variable types. With PL/SQL you can declare variables and then use them in SQL and procedural statements anywhere that an expression can be used. Variables can be used for the following: • Temporary storage of data: Data can be temporarily stored in one or more variables for use when validating data input and for processing later in the data flow process. • Manipulation of stored values: Variables can be used for calculations and other data manipulations without accessing the database. • Reusability: After they are declared, variables can be used repeatedly in an application simply by referencing them in other statements, including other declarative statements. • Ease of maintenance: When using %TYPE and %ROWTYPE (more information on %ROWTYPE is covered in a subsequent lesson), you declare variables, basing the declarations on the definitions of database columns. If an underlying definition changes, the variable declaration changes accordingly at run time. This provides data independence, reduces maintenance costs, and allows programs to adapt as the database changes to meet new business needs. More information on %TYPE is covered later in this lesson. Types of Variables" All PL/SQL variables have a data type, which specifies a storage format, constraints, and valid range of values. PL/SQL supports four data type categories—scalar, composite, reference, and LOB (large object)—that you can use for declaring variables, constants, and pointers. • Scalar data types hold a single value. The main data types are those that correspond to column types in Oracle server tables; PL/SQL also supports Boolean variables. • Composite data types, such as records, allow groups of fields to be defined and manipulated in PL/SQL blocks. • Reference data types hold values, called pointers, that designate other program items. Reference data types are not covered in this course. • LOB data types hold values, called locators, that specify the location of large objects (such as graphic images) that are stored out of line. LOB data types are discussed in detail later in this course.
