+mysql_stmt_affected_rows \- Returns the number of affected rows from

+
+my_ulonglong mysql_stmt_affected_rows(MYSQL_STMT * stmt);
+\f[R]
+.fi
+.SS Description
+.PP
+Returns the number of affected rows by the last prepared statement
+associated with mysql, if the operation was an \[lq]upsert\[rq] (INSERT,
+UPDATE, DELETE or REPLACE) statement, or \-1 if the last prepared
+statement failed.
+.SS Parameter
+.IP \[bu] 2
+\f[C]stmt\f[R] \- a statement handle, which was previously allocated by
+[mysql_stmt_init()](mysql_stmt_init().]]
+.SS Notes
+.IP \[bu] 2
+When using \f[C]UPDATE\f[R], MariaDB will not update columns where the
+new value is the same as the old value.
+This creates the possibility that \f[C]mysql_stmt_affected_rows()\f[R]
+may not actually equal the number of rows matched, only the number of
+rows that were literally affected by the query.
+.IP \[bu] 2
+The \f[C]REPLACE\f[R] statement first deletes the record with the same
+primary key and then inserts the new record.
+This function returns the number of deleted records in addition to the
+number of inserted records.
