Trap ORA errors in unix(HP-UX) shell script - oracle

Question

Script:
while read -r records
do
sErrors=`sqlplus /<<EOF
WHENEVER SQLERROR EXIT SQL.SQLCODE;
select id from table where name='"$records"';
#if select succeeds then update
update table set name='xyz';
exit;
EOF`
if [[ $sErrors = "ORAsomenumber" ]]
then
echo "Failed for $records with error:$sErrors">>logfile.log
fi
done<file
I need to trap any error specific to select query(i.e. "NO DATA FOUND") or any
Database specific error that might occur for a record in a while loop and continue
without exit till the end of reading all records
Oracle version : 10.2.0.5.0
Note: it is not mandatory to get specific ORA error only, any hint indicating the specific db error would be enough
Thanks.

file：
name1 newname1
name2 newname2
name3 newname3
script：
#!/bin/sh
#set var
export ORACLE_HOME=/oracle/product/db_1/
export ORACLE_SID=orcl
export PATH=$ORACLE_HOME/bin:$PATH
ora_user="user"
ora_pwd="password"
ora_tns="dbtnsname"
log_file=/var/log/sql.log
while read user newname
do
sqlplus -S $ora_user/$ora_pwd#$ora_tns <<EOF >>$log_file
SET SERVEROUTPUT ON
DECLARE V_ID INT DEFAULT 0;
BEGIN
SELECT ID INTO V_ID FROM TABLE WHERE NAME = "$user";
IF V_ID = 0 OR V_ID IS NULL
THEN
DBMS_OUTPUT.PUT_LINE("FAILED FOR $user WITH ERROR:NOT DATA FOUND");
ELSE
UPDATE TABLE SET NAME="$newname" WHERE NAME = "$user";
COMMIT;
END IF;
EXCEPTION
WHEN OTHERS THEN
DBMS_OUTPUT.PUT_LINE("FAILED FOR $USER WITH ERROR:"||SQLERRM);
END;
/
EOF #must top grid
done<file

The way the sqlplus invoked is fine in your script, But string comparison does not work as it contains the whole error if you want to check for some particular error code (or) only some part of the string, Use grep command.
echo $sErrors | grep "ORA-ERROR1" && echo "ORA-ERROR1 Found"
echo $sErrors | grep "ORA-ERROR2" && echo "ORA-ERROR2 Found"
In the above case, it prints both grep output and the echo command output if it matches.
If you don't want the output to be printed, You can follow the below.
echo $sErrors | grep "ORA-ERROR1" > /dev/null 2>&1
if [ $? -eq 0 ];then
echo "ORA-ERROR1 Found"
fi
