If auto-commit is disabled (see odbc_autocommit()) and you call odbc_free_result() before committing, all pending transactions are rolled back.

MDBTools driver needs you to properly free up a result_id before reusing a variable.
An odbc_fetch_array() over a overwritten variable with a new result will crash the script with a Segmentation fault if the previous resource wasn't free'd up.
