Regarding executing sql query in shell script
Hi,
I have one SQL file prepared in UNIX and one script that is executing that.
In SQL i have Update and create queries.
I want to introduce conditions in SQL file (in UNIX) that if either of the create or update query failes whole transaction should be rollback.
I just have 1 create and 2 update and i dont want to work on SQL as i want this to be sorted out using shell scripting,
Thanks

rollback
ROLLBACK(7) SQL Commands ROLLBACK(7)
NAME
ROLLBACK - abort the current transaction
SYNOPSIS
ROLLBACK [ WORK | TRANSACTION ]
DESCRIPTION
ROLLBACK rolls back the current transaction and causes all the updates made by the transaction to be discarded.
PARAMETERS
WORK
TRANSACTION
Optional key words. They have no effect.
NOTES
Use COMMIT [commit(7)] to successfully terminate a transaction.
Issuing ROLLBACK when not inside a transaction does no harm, but it will provoke a warning message.
EXAMPLES
To abort all changes:
ROLLBACK;
COMPATIBILITY
The SQL standard only specifies the two forms ROLLBACK and ROLLBACK WORK. Otherwise, this command is fully conforming.
SEE ALSO
BEGIN [begin(7)], COMMIT [commit(7)], ROLLBACK TO SAVEPOINT [rollback_to_savepoint(7)]
SQL - Language Statements 2010-05-14 ROLLBACK(7)
