I am using psql command to connect and issue a query on postgreSQL database. Can anybody let me know how to check the return status of the executed query in shell script.
I have used
psql return code is documented as:
psql returns 0 to the shell if it finished normally, 1 if a fatal error of its own occurs (e.g. out of memory, file not found), 2 if the connection to the server went bad and the session was not interactive, and 3 if an error occurred in a script and the variable ON_ERROR_STOP was set.
You probably just want to use ON_ERROR_STOP.
Failure getting tested and reported to the shell:
$ psql -d test -v "ON_ERROR_STOP=1" <<EOF select error; select 'OK'; EOF ERROR: column "error" does not exist LINE 1: select error; $ echo $? 3
Failure getting ignored and not reported to the shell:
$ psql -d test <<EOF select error; select 'OK'; EOF ERROR: column "error" does not exist LINE 1: select error; ^ ?column? ---------- OK (1 row) $ echo $? 0
