Oracle TO_DATE Function Explained with Examples
 
06:14
https://www.databasestar.com/oracle-to_date/ The Oracle TO_DATE function is one of the most useful conversion functions in Oracle. It can be a little confusing though. The TO_DATE function is used to convert a character value to a date value. You can use it to convert a string that is in the format of a date, into a date data type. Why would you use this? Converting a character to a date is helpful if you want to insert a date into a column in a table. Being specific about the format (explicit) is better than assuming the conversion will be done for you (implicit). This TO_DATE function only converts to a DATE data type. If you want to convert to the other datetime data types, you’ll have to use other functions such as TO_TIMESTAMP or TO_TIMESTAMP_TZ. The syntax for this function is: TO_DATE(charvalue [, format_mask [, nls_date_language]]) The parameters for this function are: Charvalue: This is the character value that you want to convert to a date. It’s the main input of the function. Format_mask: This is the format that the input value, the charvalue, is in. This is used to help convert your character value into a date, as your character may be in a different format to the default. Nls_date_language: this is used to determine how the output is displayed. For more information about the Oracle TO_DATE function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-to_date/

Oracle TO_TIMESTAMP Function
 
01:31
https://www.databasestar.com/oracle-to_timestamp/ The Oracle TO_TIMESTAMP function can be confusing, but we’ll explain it in this video. This function allows you to convert a string value into a TIMESTAMP value. A TIMESTAMP value is a type of DATE, but has a few components: - A date, including day, month, and year - A time, including hours, minutes, seconds, and fractional seconds This is a useful data type because it allows you to store a time down to fractions of a second. The syntax of the TO_TIMESTAMP function is: TO_TIMESTAMP ( input_string [, format_mask] [, nls_param] ) The input_string parameter is the string you want to convert. The format_mask is where you specify the format of the input_string parameter. This is so you can specify the input_string in a variety of formats, and just use this format_mask to indicate which format it is in. The nls_param parameter is another optional parameter, and allows you to specify the returning language of the month and day names. The default format will depend on the region you’re running your database in. In my example (using Oracle Express in Australia), the default format is ‘DD-MM-RRRR HH:MI:SS AM’.

Working with dates in Oracle PLSQL.
 
23:34
Dates in Oracle PL SQL is definitely the most powerful among all other databases. It gives us full flexibility to manipulate it of our choice, whether you are calculating days, months or year, printing date and time in various format. Useful date functions add_months, months_between, last_day, next_day and to_char helps us a lot in handling date time in our pl sql programming.

Oracle CURRENT_TIMESTAMP Function
 
02:37
https://www.databasestar.com/oracle-date-functions/ The Oracle CURRENT_TIMESTAMP function will display the current date and time in the session time zone. Just like the CURRENT_DATE function, it uses the session time zone, which is where you logged in from. This could be different to the database time zone. The syntax of the CURRENT_TIMESTAMP function is: CURRENT_TIMESTAMP ( [precision] ) The return type of this function is TIMESTAMP WITH TIME ZONE. The precision parameter is optional, and it lets you specify the number of fractional seconds to return. If this is omitted, it uses the default of 6. It’s different to the SYSTIMESTAMP function, because CURRENT_TIMESTAMP returns the session timezone, and SYSTIMESTAMP returns the database time zone. So, if I’m logging in from Melbourne, Australia, and the database is in London, England, then the CURRENT_TIMESTAMP will return a date and time that’s 10 hours ahead of SYSTIMESTAMP, and in a different time zone. It may be on the same day, or it could be a different day, depending on when I run the function. You can perform arithmetic on this function just like any other date value (e.g. CURRENT_TIMESTAMP - 7 for 7 days ago). However, it might be better to use interval data types so you can keep the original data type. For more information about the Oracle CURRENT_TIMESTAMP function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-date-functions/

Oracle CURRENT_DATE Function
 
01:54
https://www.databasestar.com/oracle-date-functions/ The Oracle CURRENT_DATE function is used to return the current date in the session timezone. The session timezone is the timezone that the current user is logging in from. This can be different from the database’s timezone. The syntax of the CURRENT_DATE function is: CURRENT_DATE No parameters are needed - just the function name. The function returns a DATE data type, and it includes hours, minutes, and seconds. This is good to know because the default display format for DATE does not include the time component, and it can be easy to forget. It’s different to the SYSDATE function as SYSDATE returns the date in the database timezone, and CURRENT_DATE returns the date in the session time zone. So, if I’m logging in from Melbourne, Australia, and the database is in London, England, then the CURRENT_DATE will return a date and time that’s 10 hours ahead of SYSDATE. It may be on the same day, or it could be a different day, depending on when I run the function. You can perform arithmetic on this function just like any other date value (e.g. CURRENT_DATE - 7 for 7 days ago).

Oracle DBTIMEZONE Function
 
01:17
https://www.databasestar.com/oracle-timezone-functions/ The Oracle DBTIMEZONE function returns the database timezone offset of the database. It returns it in the format of +/- TZH:TZM, or the time zone region name. It’s useful to know what timezone the database is in when working with dates and different time zones, as it can impact the queries you write. The syntax for this function is quite simple: DBTIMEZONE There are no parameters - just the function name. You can’t actually change the timezone of the database using this function. It uses the timezone of the operating system of the server the database runs on. It’s similar to the SESSIONTIMEZONE function, but that function returns the timezone of your session and not the database server. It’s also similar to the SYSTIMESTAMP function, but that function returns the date, time, and timezone of the database, where DBTIMEZONE just returns the timezone.

Oracle TO_TIMESTAMP_TZ Function
 
01:43
https://www.databasestar.com/oracle-timezone-functions/ The Oracle TO_TIMESTAMP_TZ function can be confusing, but we’ll explain it in this video. This function allows you to convert a string value into a TIMESTAMP WITH TIME ZONE value. A TIMESTAMP WITH TIME ZONE value is a type of DATE, but has a few components: - A date, including day, month, and year - A time, including hours, minutes, and seconds - A time zone, which is the number of hours and minutes difference from GMT This is a useful data type because it allows you to store dates in different time zones, and allow users in other time zones to see the data in a way that makes sense to them. The time zone part is the difference from GMT. This means that a “+7:00” is 7 hours ahead of GMT (e.g. Bangkok) and “-5:00” is 5 hours behind GMT (e.g. US Eastern Standard Time). The syntax of the TO_TIMESTAMP_TZ function is: TO_TIMESTAMP_TZ ( input_string [, format_mask] [, nls_param] ) The input_string parameter is the string you want to convert. The format_mask is where you specify the format of the input_string parameter. This is so you can specify the input_string in a variety of formats, and just use this format_mask to indicate which format it is in. The nls_param parameter is another optional parameter, and allows you to specify the returning language of the month and day names.

Oracle SQL Tutorial 29 - NCHAR Part 1
 
04:58
NCHAR is another data type available in Oracle database. This data type is very similar to the char data type with some key differences. NCHAR is also known as the national character set. This is a data type that allows us to store Unicode characters. It is really recommended that you watch the two videos over Unicode and UTF-8 because this video is going to talk a lot about it. Why is it that we have an entire data type dedicated to storing Unicode? That will be easily understood once we understand how character sets and encodings are applied to Oracle. They are applied at the database level. That means that you have a character set that applies to the entire database. This is in contrast to some database management systems that allow you to apply a data type at the table and column level. For example, in MySQL you can make a table have a character set, and make a specific column in that table a different character set. That means we can customize everything at the expense of adding potential complexity and confusion. Oracle does not work that way. In Oracle, we define one character set for the entire database. The problem with defining a character set for the entire database is that it may not be the character set we want to use for everything. That is where the NCHAR column comes in. The NCHAR column allows us to have a Unicode column inside of a database that does not use Unicode as the default character set. That is important because it is very often that we want to use Unicode but we may not need to use it for everything, for example if that application is working with ASCII nearly all of the time. If you are using Unicode for the database, then NCHAR is not going to be needed and should not be used. This data type is not as widely accepted, so only use it if you absolutely need to, specifically when you need to store Unicode in a non-Unicode database. Additionally, there is some controversy when it comes to whether or not you should use the CHAR and NCHAR data types in Oracle at all. We will discuss why in an upcoming video. In the next video we are going to go over some specific character sets that Oracle can use.

Oracle SQL Tutorial 24 - Important Data Types
 
06:09
In the upcoming videos we are going to discuss data types in depth, but I don't want to drown you in all of the details. Because of that, I'm giving you this video which is going to introduce you to the most important data types. Then, in the upcoming videos, I'll describe them in more depth. One of the data types we've already discussed in this video is NUMBER. This data type is used to, obviously, store a number. It can be used to store integers (whole numbers), or numbers with decimals. There are two other numeric data types you should know of. BINARY_FLOAT and BINARY_DOUBLE are both numeric data types that are known as floating point numbers. A floating point number is often used for large numbers that have decimal places where it is acceptable to not be completely precise. What I mean by this is that these numbers can only store numbers correctly up to a certain decimal point. If you need perfect precision, you will want to use the NUMBER data type. Now storing numbers is good sometimes, but occasionally you will want to store string data. String data can be any sequence of characters, including numbers. By telling the database that a column is a string data type, the database knows how to treat that column. There are four important string data types that you need to know about. The first two are CHAR and NCHAR. These data types are used to store a fixed-length string. So for example, you can say you want to store 12 characters. This means that every value for this column will be exactly 12 characters. If you insert less than 12 characters, the data will be padded with spaces. This means you will want to use one of these data types when every value in the column is the same length. What is the difference between CHAR and NCHAR? CHAR uses what is known as ASCII while NCHAR uses Unicode. The difference is what characters are allowed and how much space each character takes. ASCII takes up less space but only supports English, numbers, and some symbols. UNICODE allows you to store characters from multiple languages but takes up more space. Those were both fixed-length string. What if you want to store data that changes in length? That is where VARCHAR2 and NVARCHAR2 come in. When it comes to storing dates, the data types that are most important are DATE and TIMESTAMP. Date can be used to store dates and time. Timestamp is a data type that can be used to store an exact moment in time. Lastly, there are interval types. These store a date range. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

This video is going to be part 2 of NCHAR. That's because I have a bit more things to say about it before we move on to other data types. The first thing I wanted to mention is that if you declare an NCHAR(50), it is going to always be 50 characters. You do not need to use the CHAR or BYTE keyword in parenthesis to specify which you would like. We've said that NCHAR uses Unicode, but as we've learned in the last video, there are many character sets that use Unicode. Which character set is NCHAR going to use? That decision is based off of what your database's national character set is. So for every database you can declare a database character set and you can declare a national character set. The national character set is what is used for this data type. There are two options for the national character set, AL16UTF16, and UTF8. The default is AL16UTF16, which uses the utf-16 encoding. The Oracle docs has a lot of pros and cons for each one, but in general the defaults are default for a reason, so AL16UTF16 usually works fine. Now, a few videos ago I made a comment about the CHAR and NCHAR data types and how they might not be recommended. Why so? The reason is that CHAR is secretly just a VARCHAR2 that is padded to take up a full length. It does not save space nor improve performance in the database, so the chances are you are never going to want to use it. That being said, everything you've learned has not been a waste because a lot can be applied to the VARCHAR2 and NVARCHAR2 data types. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

Please subscribe and like my videos, it means a TON to me. Thanks :) This is simply a small course to introduce you to all of the datatypes(excluding spatial, which I will not be covering in this course). All of the datatypes are broken into 4 sections, these are Numeric, Date and Time, String, and Spatial. In all, these are the datatypes I will be covering: tinyint, smallint, mediumint, int, bigint, decimal, float, double, real, bit, boolean, serial, date, datetime, timestamp, time, year, char, varchar, tinytext, text, mediumtext, longtext, binary, varbinary, tinyblob, mediumblob, blob, longblob, enum, and set. Wooah that's a lot. haha. I will not be going over geometry, point, linestring, polygon, multipoint, or multilinestring. If you want to learn more about Spatial types, start here: http://dev.mysql.com/doc/refman/5.6/en/mysql-spatial-datatypes.html Want more information about what is covered in these videos? Always be sure to read the supporting page in the MySQL manual. http://dev.mysql.com/doc/refman/5.6/en/index.html Video information: Char and Varchar ___________________________ Char has a character range from 0 up to 255, varchar allows up to 65535. a max length can be specified in parenthesis such as char(40). char is right padded to fit the specified amount of characters, and the spaces are then removed on retrieval. Only trailing spaces will be removed. for example. Cat_hat__ will come out as cat_hat. This can be a bad thing if you need to store spaces. you will need to use varchar instead. If a value entered is too long, it will be "truncated," or cut to length. Extra info ________ a character set is an allowed range of characters that are entered into an entry. such as UTF-8. Utf 8 is 3 bytes for every character. the storing information for varchar and char are like this.. char - string length. varchar - string length+1. A 10 character entry using UTF-8 would then take 30 bytes in char, and 31 bytes in varchar, but if only 5 characters are entered, it will be 30 bytes for char, and 16 for varchar. This is because char stores the trailing spaces till the requested size is full (in this case 10). A table maximum row size is 65535, so this means if you have a varchar 65535 that is completely full in one column, that is the max allowed stored across that column. Any corrections needing made in these videos please message me. Thank you!
