I dont think u need the pgm flow....coz, its quite simple....but I can throw some light on how to connect to oracle from c program...and other statements.


1.Connect to Oracle
EXEC SQL CONNECT :<OracleUID>;

2. Insert into table.
EXEL SQL INSERT INTO <Tablename> ( field1, field2 , ...)
VALUES ( :var_field1, :var_field2 , ...);

3. Commit the work.
EXEC SQL COMMIT WORK;

4. To roll back the work.
EXEC SQL ROLLBACK;

5. Release Oracle connection.
EXEC SQL ROLLBACK WORK RELEASE;


And.....all exception conditions should also be handled after each EXEC SQL statement. (SQLERROR, NOTFOUND, NOORACLE etc)


Will that do?

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)
