Answer 1

I cannot use util_file .
I am ussing dbms_output.put . Thats fine .
i am spooling currently
I want to know how I can set the SET variables that only the dbms_output.put variables are spooled to the .
When you do spool get all the command s?.
Currently i am doing this
$ORACLE_HOME/bin/sqlplus -s <<EOI
$CONNECT_STR
WHENEVER SQLERROR EXIT FAILURE;
SET FEED OFF TERM OFF
SET SERVEROUTPUT ON
SPOOL $SQL_LOG
BEGIN
${PROCESS_SCHEMA_NM}.${STORED_PROC}.CONVERT_FLEX_2_TIMESHEET;
END;
is this correct ?
