#38475 [NEW]: mysql_error doesn't reset after mysql_* func call
From: mirya at matrix dot ua
Operating system: FreeBSD6.1
PHP version: 5.1.4
PHP Bug Type: MySQL related
Bug description: mysql_error doesn't reset after mysql_* func call
Description:
------------
Extract from mysql_error() php doc page:
"Note that this function only returns the error text from the most
recently executed MySQL function (not including mysql_error() and
mysql_errno())..."
I noticed that a error is not reset for mysql_fetch_*() call
(server/client 5.0.22), mean if you perform mysql_query() for some data
manipulation statement producing a error, then call mysql_fetch_*(),
mysql_error() will return mysql_query() error message.
So the docs page is inconsistent with current mysql lib behaviour
Reproduce code:
---------------
mysql_connect('localhost', 'mirya', 'my-passwd');
mysql_select_db('test');
mysql_query('CREATE TABLE a (a INT AUTO_INCREMENT PRIMARY KEY) ENGINE =
InnoDB');
mysql_query('CREATE TABLE b (b INT AUTO_INCREMENT PRIMARY KEY, a INT NOT
NULL, FOREIGN KEY (a) REFERENCES a(a) ON DELETE REST
mysql_query('INSERT a VALUES (1), (2), (3)');
$rs = mysql_query('SELECT a FROM a');
while ($row = mysql_fetch_assoc($rs)) {
if (mysql_error()) die('Shouldn\'t happen: '.mysql_error());
mysql_query('INSERT b (a) VALUES (4)');
if (mysql_error()) echo "Foreign key constraint fails\n";
}
echo "Finished w/o errors\n";
Expected result:
----------------
Foreign key constraint fails
Finished w/o errors
Actual result:
--------------
Foreign key constraint fails
Shouldn't happen: Cannot add or update a child row: a foreign key
constraint fails (test/b, CONSTRAINT b_ibfk_1 FOREIGN KEY (a)
REFERENCES a (a))
