Question

I am executing a bunch of SQL scripts using SQLCMD, and redirecting the output to a log file using the -o switch. How do I turn off the output of SELECT queries? Errors, if any, should still be written to the log file, as usual.

Answer 1

If you want to log only errors, log by redirecting STDERR rather than by using the -o switch:

SQLCMD -S server -d database -E -r0 -Q "select 1" 2> error.log

update
Added that the -r0 switch must be set to redirect errors to STDERR
