sybase_affected_rows

(PHP 3 >= 3.0.6, PHP 4, PHP 5)

sybase_affected_rows -- Gets number of affected rows in last query

Description

int sybase_affected_rows ( [resource link_identifier] )

sybase_affected_rows() returns the number of rows affected by the last INSERT, UPDATE or DELETE query on the server associated with the specified link identifier. If the link identifier isn't specified, the last opened link is assumed.

Пример 1. Delete-Query

<?php
/* connect to database */
sybase_connect('SYBASE', '', '') or
die("Could not connect");
sybase_select_db("db");

sybase_query("DELETE FROM sometable WHERE id < 10");
printf("Records deleted: %d\n", sybase_affected_rows());
?>

Результат выполнения данного примера:

Records deleted: 10

This command is not effective for SELECT statements, only on statements which modify records. To retrieve the number of rows returned from a SELECT, use sybase_num_rows().

The sybase_affected_rows() function seems to work now with the Sybase DB Library.  Not sure when this improvement was made, but I'm currently running PHP 4.1.2 on Solaris.

Affected rows seems to return a -1 if the query syntax was incorrect on the last submitted query.
Affected rows returns 0 if no rows were affected or another error occured, such as a foreign key violation and also returns 0 if the query was successfully, but no records were affected by the query.
If the query was valid and did affect some rows, sybase_affected_rows() seems to be returning the correct number.

If you get a segfault with sybase-ct, add a en_US entry to your $SYBASE/locales/locales.dat file:
<PRE>
[linux]
    locale = en_US, us_english, iso_1
    ...
</PRE>
