<para>

<function>mysqli_stmt_affected_rows</function> returns the number of rows affected
|
|
by INSERT, UPDATE, or DELETE query. If the last query was invalid, this function will return -1.

</para>

<note>
|
|
<para>
|
|
For SELECT statements <function>mysqli_affected_rows</function> works like
|
|
<function>mysqli_num_rows</function>.
|
|
</para>
|
|
</note>
|
|
<para>
|
|
The <function>mysqli_stmt_affected_rows</function> function only works with queries
|
|
which update a table. In order to return the number of rows from a SELECT query, use
|
|
the <function>mysqli_stmt_num_rows</function> function instead.

<para>
|
|
An integer greater than zero indicates the number of rows affected or retrieved.
|
|
Zero indicates that no records where updated for an UPDATE/DELETE statement, no
|
|
rows matched the WHERE clause in the query or that no query has yet been executed.
|
|
-1 indicates that the query has returned an error.
|
|
</para>
|
|
<note>
|
|
<para>
|
|
If the number of affected rows is greater than maximal PHP int value, the number of
|
|
affected rows will be returned as a string value.
