Description:
------------
I have a table likes:
plant    char(4),
partID   char(18),
movementType char(3),
txnDate  char(8),
quantity int,
price    smallmoney

I got php.exe freezing while I was trying to query this table by php. I checked process info on SQL management window and found query was not closed. I must kill this process id. Sometimes wait type is sleeping, sometimes is NETWORKIO. First, I just suspend server has not enough socket memoy space and sql server can't write result back. Finally I found it's maybe php's fault. 
When I change price's type to float from smallmoney, I fixed this rpoblem. No any query jam happens. I guess maybe php treats smallmoney's byte length different as SQL server do. Even though SQL server return everything back, php.exe still think serveral bytes will be coming. Just my 2 cents. P.S. SQL server is running on the simplify chinese w2k server.

Reproduce code:
---------------
	$date1=date("Ymd",strtotime($date1));
	$date2=date("Ymd",strtotime($date2));
	$query = "select * from sapinout where txnDate>='$date1' and txnDate<='$date2'";
	$queryResult = $AMC_DB->query($query);
	$header="Date\t";
	$header.="Plant\t";
	$header.="Part ID\t";
	$header.="Movement Type\t";
	$header.="Quantity\t";
	$header.="Price";
	$data="";
	while ( $row = mssql_fetch_array($queryResult) )
	{
		$line="";
		$value = '"' . $row[txnDate] . '"' . "\t"; $line .= $value;
		$value = '"' . $row[plant] . '"' . "\t"; $line .= $value;
		$value = '"' . $row[partID] . '"' . "\t"; $line .= $value;
		$value = '"' . $row[movementType] . '"' . "\t"; $line .= $value;
		$value = '"' . $row[quantity] . '"' . "\t"; $line .= $value;
		$value = '"' . $row[price] . '"' . "\t"; $line .= $value;
		$data .= trim($line)."\n";
	}

Expected result:
----------------
Will return result immedately!

Actual result:
--------------
No any return from web server.
