If you are using transactions, you need to call

<function>mysql_affected_rows</function> after your INSERT,

If the last query was a DELETE query with no WHERE clause, all

<para>
|

When using UPDATE, MySQL will not update columns where the new
|
||||
value is the same as the old value. This creates the possibility
|
||||
that <function>mysql_affected_rows</function> may not actually
|
||||
equal the number of rows matched, only the number of rows that
|
||||
were literally affected by the query.

</para>

<para>

The REPLACE statement first deletes the record with the same primary key and

then inserts the new record. This function returns the number of deleted

records plus the number of inserted records.
