  • Run a Stored Procedure when SQL Server starts

    Steps to Run a Stored Procedure when SQL Server starts

    As you all know, when SQL Server starts, it will first scan the registry to get the startup parameter values. By scaning registry it will find the master database files first and then make the master database online.

    So if you want a procedure to execute when SQL Server starts automatically, you have to create that procedure in Master database only.

    Step 1: Create a procedure in master database

    Step 2: We have to use sp_procoption to set the stored procedure to execute when SQL Server service starts. Please see the example below.

    EXEC sp_procoption 'procedure name', 'startup', 'true'

    Step 3: Restart the SQL Service, to check the procedure output.

    How turn off startup procedure?
    You can turn-off the procedrue execution using below query.
    EXEC sp_procoption 'procedure name', 'startup', 'false'

  • Master..spt_values system table

    SPT_Values is un-documented table. It seems it is available from Sybase days and it is used in system stored procedures to translate codes into readable strings.
    It stores the specific number of each SQL Server Property. If you execute below query, you can get the diffrent kind of result and you can use it as per the need.

    select min(number) FROM master..spt_values
    –Output
    -32768

    select min(number) FROM master..spt_values where number > 0
    — Output
    1
    select max(number) FROM master..spt_values
    — Output
    1469283328

    You can use to generate number from 1 to 2048 as well.

    SELECT distinct number
    FROM master..spt_values
    WHERE number BETWEEN 10 AND 15

  • Unable to change autogrowth properties of SQL Server of log file

    Problem
    People often complains that they are unable to change the Log File Growth to un-restricted.

    Solution
    Whenever we are chaging max size as unlimited for log file, SQL Server reset the Max Size avalue to 2TB and this is the max size supported for log file. This is by design only.
