Oracle REPLACE Function
 
03:55
https://www.databasestar.com/oracle-replace/ The Oracle REPLACE function is a string manipulation function that allows you to replace one text string with another. It can be a whole word or sentence, or even a single value. The syntax of the REPLACE function is: REPLACE ( whole_string, string_to_replace, [replacement_string]) To use this function, the parameters are: - whole_string (mandatory): This is the string that will be checked for the characters to be replaced. - string_to_replace (mandatory): This is the string that will be searched for within whole_string. - replacement_string (optional): This is the string that will be used to replace occurrences of string_to_replace. Because the last parameter is optional, if it is not specified, then the Oracle REPLACE function removes all occurrences of string_to_replace. You can replace carriage returns with REPLACE, but you’ll need to use the CHR function. You can replace NULL values in Oracle, but this is best done with another function such as NVL, rather than REPLACE. If you want to replace multiple characters, you can do this using nested REPLACE functions or a REGEXP_REPLACE function. For more information about the Oracle REPLACE function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-replace/

Oracle LTRIM Function
 
03:06
https://www.databasestar.com/oracle-trim/ The Oracle LTRIM function allows you to remove a specific character from the left side of a string. It’s one of the most commonly used string manipulation functions in SQL, in my experience. The “L” in “LTRIM” stands for “left”. It’s often used to remove spaces from the left of a string. However it can be used to remove other characters, such as leading characters from URLs. The syntax for the LTRIM function is: LTRIM(input_string, [trim_character]) The input_string is the text you want to remove characters from. It can be any kind of expression, such as a specific text value or a column. The trim_character is the character you want to remove from the left of the string. It’s an optional parameter, and if you don’t specify it, then a space character is used by the function. The parameters can be any type of string. The function will return either a VARCHAR2 or a LOB data type, depending on the type of data you specify in the parameters. You can specify more than one value for the trim_character, and the LTRIM function will remove both characters from the left of the string. The function is similar to the RTRIM value, where RTRIM removes characters from the right of the string. For more information on the LTRIM function, including the SQL used in this video, read the related article here: https://www.databasestar.com/oracle-trim/

Oracle NVL Function Explained with Examples
 
09:25
https://www.databasestar.com/oracle-nvl-nvl2-logical-functions/ The Oracle NVL function allows you to check a value and return a different value if that value is NULL. It’s great for using another value if the first one is NULL or an optional value, for example people’s phone numbers. It’s also good alongside aggregate functions and grouping so you can see what the difference is between a subtotal row and an actual NULL value. The syntax of the Oracle NVL function is: NVL( check_value, replace_value ) The parameters are: - check_value (mandatory): This is the value that is displayed to the user. It is also the value that is checked for NULL. - replace_value (mandatory): This is the value that appears if the check_value is NULL. The function can use many different data types as parameters: string, date, or numeric. However, both parameters need to be the same type.

Oracle DECODE Function
 
04:31
https://www.databasestar.com/oracle-decode-function/ The Oracle DECODE function lets you perform IF-THEN-ELSE functionality in your queries. It’s similar to a CASE statement. The syntax of the DECODE function is: DECODE ( expression, search, result [, search, result]... [,default] ) The parameters of the Oracle DECODE function are: - expression (mandatory): This is the value to compare. - search (mandatory): This is the value to compare against the expression. - result (mandatory): This is the return value if the search value matches the expression value. There can be multiple combinations of search and result values, and the result value is attached to the previous search value. - default (optional): If none of the search values match, then this value is returned. If this is not provided, the DECODE function will return NULL if no matches are found. If you compare this to an IF-THEN-ELSE statement, it would look like this: IF (expression = search) THEN result [ELSE IF (expression = search) THEN result] ELSE default END IF The parameters can be one of many different data types, and the return type is calculated from them. Earlier I mentioned it’s similar to CASE. So why would you use one and not the other? - DECODE is an older function, and CASE was introduced as a replacement for DECODE. - CASE offers more flexibility then DECODE - CASE is also easier to read and debug (in my opinion) The performance of these functions is the same, so if you’re considering using DECODE, I would suggest using CASE instead. For more information about the Oracle DECODE function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-decode-function/

Let's see the Syntax Substr (source_string, start_pos, Substr_length) As we can see SQL substr function takes 3 parameters. First one is Source string from which you want to extract the segment. Second parameter is Starting position for sub string from the Source string. And the third parameter is Substr_length which is the length for the substring. First two parameters are mandatory to specify while third one is optional. So we can say. SQL Substr function will return a sub string of a specified length from the source string beginning at a given position. First parameter source string can be of any data type CHAR, VARCHAR2, NCHAR, NVARCHAR2, CLOB, or NCLOB whereas both start_pos, Substr_length parameters must be number data type. The returning result of SQL Substr function is of same data type of source string. Let's see an example of SQL Substr function. SELECT substr('www.RebellionRider.com',5,14) FROM dual; Here in this query url of my website www.RebellionRider.com is our source string with the total length of 22 characters, Now, I want to extract the name of my website that is, RebellionRider. So if you count the total length of the name of the website, it is 14. That's why I have specified 14 as my third parameter of SQL Substr function which is substr_length. Also the name of the website RebellionRider is starting from 5th position therefore I have specified 5 at second parameter of SQL substr function which is strt_pos or starting position. Execute it. Here is our result RebellionRider When starting position is larger than the length of source string. In this case SQL Substr function will return NULL as a result. Let's do an example. SELECT substr('www.RebellionRider.com',23,14) FROM dual; As you can see here I have specified 23 at starting position and the total length of our source string is 22 characters Let's execute And the result is Null. Second scenario When the Substr_length is greater than source string In this case the segment return is the substring from starting position to the end of the string. For example SELECT substr('www.RebellionRider.com',5,23) FROM dual; Our starting position is at 5 means at the first R of RebellionRider and length of substring is set to 23 which is greater than the length of source string that is 22. Execute. As you can see we get a substring from first R of RebellionRider till the end of the source String. Third scenario When you supply numeric or arithmetic expression or a DATE instead of character as Source string to SQL Substr function In this scenario If you have supplied a numeric string instead of character as source string, the oracle engine casts them as a character when they occur as parameter to SQL Substr function. And if you have supplied Arithmetic expression or a DATE then The Oracle engine first solves or evaluates the Arithmetic expression or the DATE Then casts them as a character. Means if you have arithmetic expression in your source string then oracle will first solve it and then change or say cast the value of its result into character. Let's see some example. SELECT substr(50000-7,2,4) FROM dual; Oracle first evaluates the arithmetic expression that is 50000-7 equals to 49993. And then oracle engine casts this result 49993 into a character string. Means 49993 will be a 5 characters string. Starting position of substring is 2, that means from the first 9 of 49993 We specified the length of substring is 4 so we must get 9993 as our result. Let's check execute

Grouping function in SQL Server
 
12:49
sql server rollup grouping sql server rollup replace null sql server rollup grouping replace null In this video we will discuss the use of Grouping function in SQL Server. This is continuation to Part 104. Please watch Part 104 from SQL Server tutorial before proceeding. What is Grouping function Grouping(Column) indicates whether the column in a GROUP BY list is aggregated or not. Grouping returns 1 for aggregated or 0 for not aggregated in the result set. The following query returns 1 for aggregated or 0 for not aggregated in the result set SELECT Continent, Country, City, SUM(SaleAmount) AS TotalSales, GROUPING(Continent) AS GP_Continent, GROUPING(Country) AS GP_Country, GROUPING(City) AS GP_City FROM Sales GROUP BY ROLLUP(Continent, Country, City) What is the use of Grouping function in real world When a column is aggregated in the result set, the column will have a NULL value. If you want to replace NULL with All then this GROUPING function is very handy. SELECT CASE WHEN GROUPING(Continent) = 1 THEN 'All' ELSE ISNULL(Continent, 'Unknown') END AS Continent, CASE WHEN GROUPING(Country) = 1 THEN 'All' ELSE ISNULL(Country, 'Unknown') END AS Country, CASE WHEN GROUPING(City) = 1 THEN 'All' ELSE ISNULL(City, 'Unknown') END AS City, SUM(SaleAmount) AS TotalSales FROM Sales GROUP BY ROLLUP(Continent, Country, City) Can't I use ISNULL function instead as shown below SELECT ISNULL(Continent, 'All') AS Continent, ISNULL(Country, 'All') AS Country, ISNULL(City, 'All') AS City, SUM(SaleAmount) AS TotalSales FROM Sales GROUP BY ROLLUP(Continent, Country, City) Well, you can, but only if your data does not contain NULL values. Let me explain what I mean. At the moment the raw data in our Sales has no NULL values. Let's introduce a NULL value in the City column of the row where Id = 1 Update Sales Set City = NULL where Id = 1 Now execute the following query with ISNULL function SELECT ISNULL(Continent, 'All') AS Continent, ISNULL(Country, 'All') AS Country, ISNULL(City, 'All') AS City, SUM(SaleAmount) AS TotalSales FROM Sales GROUP BY ROLLUP(Continent, Country, City) Notice that the actuall NULL value in the raw data is also replaced with the word 'All', which is incorrect. Hence the need for Grouping function. Please note : Grouping function can be used with Rollup, Cube and Grouping Sets Text version of the video http://csharp-video-tutorials.blogspot.com/2015/09/grouping-function-in-sql-server.html Slides http://csharp-video-tutorials.blogspot.com/2015/09/grouping-function-in-sql-server_25.html All SQL Server Text Articles http://csharp-video-tutorials.blogspot.com/p/free-sql-server-video-tutorials-for.html All SQL Server Slides http://csharp-video-tutorials.blogspot.com/p/sql-server.html All Dot Net and SQL Server Tutorials in English https://www.youtube.com/user/kudvenkat/playlists?view=1&sort=dd All Dot Net and SQL Server Tutorials in Arabic https://www.youtube.com/c/KudvenkatArabic/playlists
