The Oracle SQL driver is not working correctly, executing the attached test, all tuples after the rollback remain on the table, the patch is the following for qsql_oci.cpp :

< const bool *transaction;
—
> bool transaction;
1534c1534
< *d->transaction ? OCI_DEFAULT : OCI_COMMIT_ON_SUCCESS);
—
> d->transaction ? OCI_DEFAULT : OCI_COMMIT_ON_SUCCESS);
1770c1770
< sql(0), transaction(&driver->transaction), serverVersion(driver->serverVersion),
—
> sql(0), transaction(driver->transaction), serverVersion(driver->serverVersion),

< mode = *d->transaction ? OCI_DEFAULT : OCI_COMMIT_ON_SUCCESS;
—
> mode = d->transaction ? OCI_DEFAULT : OCI_COMMIT_ON_SUCCESS;
