Operating system: MS-Win2000 SP4
PHP version: 5.0.4
PHP Bug Type: Unknown/Other Function
Bug description: recordset crash on trim and on fields with value null
Description:
------------
Database: MS-SQL Server 2000 (in case it is important)
See code below.
Expecting it to NOT hang forever and produce some output.
Unfortunately - if ANY of the lines with crash comment behind them is
present it will hang forever (until web-server timeout).
'user' - is a present field of type char(20) and value is never NULL.
'kursjuh' - is a present field of type char(1) and will result a crash
only if field value is NULL.
PHP fails to produce error log - so, no info there.
Reproduce code:
---------------
$db=new COM("ADODB.Connection");
$db->Open("Driver={SQL Server};Server=***;Database=***;");
$dta=$db->Execute("SELECT * FROM Qigus");
while(!$dta->EOF) {
echo $dta->Fields['kursjuh']->Value; // crash
echo $dta['kursjuh']; // crash
echo $dta['user']; // works fine
echo trim($dta['user']); // crash
$dta->MoveNext(); }
