Обсуждение: plpgsql: Checking status on a 'INSERT INTO ...'

I'm porting some stored procedures from a MSSQL server, and thought
I'd use PL/pgSQL.

The original code is checking the insert with the line:
       if (@@Error != 0)

How do I do the same thing in PL/pgSQL?

You might want to use something like:

SELECT INTO variable_name * FROM tableWHERE field = some_value;

IF FOUND THEN somevar := variable_name.fieldname ;
ELSE RAISE EXCEPTION ''ERROR blah blah'';
END IF;

And you also want to look into the @@rowcount:

GET DIAGNOSTICS v_rowcount = ROW_COUNT ;
