Good question and equally good explanation. 🙂

Be aware of case:

DECLARE @STR VARCHAR(8000) = N'SELECT * FROM sys.objects'

EXECUTE SP_EXECUTESQL @STR

It should be:

DECLARE @STR VARCHAR(8000) = N'SELECT * FROM sys.objects'

EXECUTE sp_executesql @STR

🙂

It should be underlined that this

[font="Courier New"]DECLARE @STR VARCHAR(8000) = N'SELECT * FROM sys.objects'

EXECUTE SP_EXECUTESQL @STR[/font]

works on MSSQL 2008 -->

On MSSQL 2005 it returns

[font="Courier New"]Msg 139, Level 15, State 1, Line 0

Cannot assign a default value to a local variable.[/font]

Equivalent for 2005 is:

[font="Courier New"]DECLARE @STR VARCHAR(8000)

SET @STR = N'SELECT * FROM sys.objects'

EXECUTE SP_EXECUTESQL @STR[/font]

Nice idea, but not sure about the execution. I knew it was going to fail due to the data type, but any of the options was feasible so it came down to a guess as to which one the MS developers decided to return. Luckily I guessed right 🙂

Thanks for adding this. Lot of guys I know have directly started working from 2008. This is helpful for them.

DECLARE @STR VARCHAR(8000) = N'SELECT * FROM sys.objects'
EXECUTE sp_executesql @STR
🙂

Only if the instance is case sensitive 🙂

In that case the correct answer would be

Msg 2812, Level 16, State 62, Line 3
Could not find stored procedure 'SP_EXECUTESQL'.
