When called multiple times in a single batch, rand() returns the same number. So it is better to use convert(varbinary,newid()) as the seed argument: SELECT 1.0 + floor(110 * RAND(convert(varbinary, newid()))) AS random_number newid() is guaranteed to return a different value each time it’s called, even within the same batch, so using it as a seed […]
— Set Identity insert on so that value can be inserted into this column SET IDENTITY_INSERT YourTable ON GO — Insert the record which you want to update with new value in the identity column INSERT INTO YourTable(IdentityCol, otherCol) VALUES(5, ‘myValue’) GO — Delete the old row of which you have inserted a copy (above) […]
–View the current value: DBCC CHECKIDENT (“{table name}”, NORESEED) –Set it to the max value plus one: DBCC CHECKIDENT (“{table name}”, RESEED) –Set it to a spcefic value: DBCC CHECKIDENT (“{table name}”, RESEED, {New Seed Value})

SELECT DATEADD(MONTH, DATEDIFF(MONTH, 0, GETDATE())-1, 0) –First day of previous month SELECT DATEADD(MONTH, DATEDIFF(MONTH, -1, GETDATE())-1, -1) –Last Day of previous month
CONCAT function ignores NULLs: SELECT CONCAT(LEFT(LastName, 1), ‘,’ , LEFT(FirstName, 1), ‘ ‘ + LEFT(MiddleName, 1)) theNameWithInitials FROM myTable If you use CONCAT, you will not need to worry about whether LEFT(X) is null or not.
The DBCC CHECKIDENT management command is used to reset the identity counter. The command syntax is: DBCC CHECKIDENT (table_name [, { NORESEED | { RESEED [, new_reseed_value ]}}]) [ WITH NO_INFOMSGS ] Example: DBCC CHECKIDENT (‘[TestTable]’, RESEED, 0); IMPORTANT: The following example forces the current identity value in the AddressTypeID column in the AddressType table to a value […]
To create a single string from multiple rows in MySQL, you can use the GROUP_CONCAT function. This function allows you to concatenate values from multiple rows into a single string, separated by a specified delimiter. Here is an example of how you can use this function: SELECT GROUP_CONCAT(column_name ORDER BY column_name ASC SEPARATOR ‘,’) FROM […]

Recursive triggers are set at the database level. It’s part of the database metadata information and is available through “sys.databases” view. You can use the below query to check whether the recursive triggers are enabled or not on your database: SELECT name AS ‘Database’, is_recursive_triggers_on AS ‘Recursive Trigger Enabled’ FROM sys.databases Here is the output:
The SQL Server CONCAT_WS() function concatenates two or more strings into one string with a separator. CONCAT_WS() means concatenate with separator.
