Sp_Configure procedure is used to display or change the SQL Server setting. Once you execute the SP_Configure procedure it will display the below columns in the output.
name – Name of the configuration parameter
minimum – Minimum value setting that is allowed
maximum – Maximum value that is allowed
config_value – value which currently configured
run_value – value which currently running
How to update the configuration value?
Here I will show you how to enable the XP_CmdShell using SP_Configure. Please note don’t update configuration values until you are sure, otherwise it will affect the your SQL Server performance and behavioral.
--XP_Cmdshell is an andvanced option, enbale the advanced option EXEC sp_configure 'show advanced options', 1 GO --Enable the advance option RECONFIGURE GO --enable the xp_cmdshell EXEC sp_configure 'xp_cmdshell', 1 GO --Reconfigure the xp_cmdshell value RECONFIGURE GO
What is the difference between Config_Value and Run_Value?
When we change the Configuration Parameter value as above it will update the Config_Value filed only, but wouldn’t be in effect until you run reconfigure command. Once the reconfigure command execute or SQL Server restarted, SQL Server will run as per the new configured value.
You can get the description of the configuration parameters from books online or you can query sys.configurations and check for the description column.
