<function>fbsql_affected_rows</function> returns the number

associated with <parameter>link_identifier</parameter>.

<para>

|
If you are using transactions, you need to call
|
|
<function>fbsql_affected_rows</function> after your INSERT,
|
|
UPDATE, or DELETE query, not after the commit.
|
|
</para>
|
|
</note>
|
|
<para>
|
|
If the last query was a DELETE query with no WHERE clause, all of
|
|
the records will have been deleted from the table but this
|
|
function will return zero.
|
|
</para>
|
|
<note>
|
|
<para>
|
|
When using UPDATE, FrontBase will not update columns where the
|
|
new value is the same as the old value. This creates the
|
|
possibility that <function>fbsql_affected_rows</function> may not
|
|
actually equal the number of rows matched, only the number of
|
|
rows that were literally affected by the query.
