In online programs, why we perform an
EXEC CICS SYNCPOINT ROLLBACK END-EXEC, for unsuccessful sqls?
Is it possible to replace it by EXEC SQL ROLLBACK END-EXEC,
Please guide what CICS SYNCPOINT ROLLBACK does? |

EXEC SQL ROLLBACK will only rollback the database work done. Any other updates performed by CICS in the unit of work will not be rolled back.
EXEC CICS SYNCPOINT (ROLLBACK) performs a two-phase COMMIT (ROLLBACK) of all resources affected by the CICS unit-of-work.

No, not if you value the integrity of your data.

Why do you believe this might be possible? |

I understand that it is not possible to use EXEC SQL ROLLBACK, actually i am sure what are the CICS rolback does other than rolling back 'DB2 updation'. |
