(Doc ID 552815.1)
Last updated on FEBRUARY 03, 2022
Applies to:SQL*Plus - Version 10.2.0.1 and later
Information in this document applies to any platform.
Host commands from sqlplus on version 10g always returns zero not trapping the error when logged into the database without connect string (<USER>/<PASSWORD>). However, when logged into the database with connect string (<USER>/>PASSWORD>@<CONNECT_STRING>), host commands are able to trap any error and returns non-zero.
Steps to reproduce:
1. export TBL1="abcde:fghij"
2. export TBL2="ABCDE"
3. Log into database without connect string (<USER>/<PASSWORD>)
4. SQL> !print "$TBL1" | grep ":";echo $?
5. SQL> !print "$TBL2" | grep ":";echo $?
0 -> This is incorrect result, it should return 1
6. Logout and login again with connect string (<USER>/>PASSWORD>@<CONNECT_STRING>) and execute repeat steps 4 and 5 , it will return proper results.
Upgrade database from 9i or older to 10g.
