Trigger mit PHP-Script: DELIMITER-Problem

[Sven Reuter]

Hallo NG,

ich versuche gerade ein PHP-Script zu bauen, das einen Trigger in einer
MySQL-Datenbank erstellt.

Doch leider funktioniert das nicht und ich habe auch über google keine
Hinweise gefunden. Ich vermute, dass es am Delimiter liegt.

Der Code, der per PHP abgeschickt wird:

DELIMITER |
CREATE TRIGGER ext4cAnbieter_d el AFTER DELETE ON anbieter
FOR EACH ROW BEGIN
DELETE FROM ext4cSupportfor m WHERE anbieter = OLD.anbieter;
END;
|
DELIMITER ;
Die Syntax ist laut MySQL-Doku [1] korrekt. Im phpMyAdmin wird der Code
(ohne die DELIMITER-Statements, aber mit Angabe dessen im entsprechenden
Feld) auch angenommen.
Versionen:
PHP 5.2
MySQL 5.0.32
Weiß jemand Rat?

Danke!

Gruß...Sven.

Sorry for that. I worked all the day so that I didn't realized that :-(

Here an english version of my post:
I try to write a PHP script that should create a trigger in a MySQL
database.

But it don't work and I don't found hints at google. I assume a problem
with the DELIMITER.

Here's the Code sent by the PHP script:

DELIMITER |
CREATE TRIGGER ext4cAnbieter_d el AFTER DELETE ON anbieter
FOR EACH ROW BEGIN
DELETE FROM ext4cSupportfor m WHERE anbieter = OLD.anbieter;
END;
|
DELIMITER ;

The syntax correct according to MySQL-Doc [1]. In phpMyAdmin the code is
executed well (without DELIMITER statements but with delimiter
expression in the analogical form field).

versions:
PHP 5.2
MySQL 5.0.32
Can anyone help?

Thx!

Bye...Sven.

I wrote my post in an english version again in reply to Jensens post.
I think it's not a problem of MySQL.

Is it?

By golly, and there was me thinking it was a worldwide group.

You aren't showing any PHP code, and only asking about SQL code.

comp.databases. mysql is the correct group to be asking in.

However the SQL code works, except when embedded into php..

Things to check.

- PHP user has sufficient privileges to access the database in this way:
the phpmyadmin program my not connect to the database as the same user.

- no hidden charcter replacement to the query string is being performed
my the php->mysql shim library.

turn on all error reporting a well.

Yes, that's right. I think I've found a solution for my problem:

Although MySQL requires DELIMITER statements it's not possible to use
them in PHP. I've just sent the statement for the trigger and it worked
(encapsulated in PHP code especially for Jerry ;-) ):

$result = mysql_query('CR EATE TRIGGER ext4cAnbieter_d el AFTER DELETE ON
anbieter FOR EACH ROW BEGIN DELETE FROM ext4cSupportfor m WHERE anbieter
= OLD.anbieter; END;');

`Be kind to Jerry. He's really past it these days..

$result = mysql_query('CR EATE TRIGGER ext4cAnbieter_d el AFTER DELETE ON

Ee Bai Gum kad, that were a strangling of t'English language.

Which is the answer you would have gotten very quickly had you asked in
the correct newsgroup.

This isn't a PHP issue - it's true when you create a trigger using ANY
language APIs. That includes C, Java and any other supported language,
not just PHP.

Here's a hint. PHP knows absolutely NOTHING about CREATE TRIGGER or
similar SQL statements. They're just strings to PHP - which are passed
on to MySQL for processing.

So maybe next time you'll ask in the correct newsgroup - and get an
answer.
