oracle - Sql*plus always returns exit code 0?

Question

Whenever I run a sql script using Sql*plus and check for $?, I get 0 even when the script wasn't succesful.

Example

#$ sqlplus user/password@instance @script.sql

$ echo $?

I would like it to return a non-zero value when an error occurs.

How can I achieve that ?

Answer 1

You have to explicitly tell sqlplus to do that, in your script. Basically, there are two statements that you can use:

• WHENEVER SQLERROR EXIT SQL.SQLCODE
• WHENEVER OSERROR EXIT

For example:

WHENEVER SQLERROR EXIT SQL.SQLCODE
begin
  SELECT COLUMN_DOES_NOT_EXIST FROM DUAL;
END;
/

And for OS errors:

WHENEVER OSERROR EXIT FAILURE
START no_such_file

For more information, see this and that.

Hope it helps. Good Luck!
