Question

If i run a sql EXEC() command, then how i confirm that the command is executed properly.Because i don’t find any success/failure return type of this command.
Let say my command is:

EXEC('INSERT into '+@t1+'('+@c1+') values ('+@v1+')')

or any other way to be confirm that, the command is execute properly into the destination table.

Answer 1

Try to use global variable @@rowcount after a exec command:

select @@rowcount 

It displays rows affected by the last command.

If you want to catch an exception:

BEGIN TRY
   EXEC('fake code') 
   select @@rowcount -- if exec works correctly 
END TRY
BEGIN CATCH
    PRINT N'Your message';
END CATCH;

MSDN about try-catch.
