I don't think this is a PHP problem. Try this: Modify your script so that it looks like: 1| $sql=mysql_query("SELECT id FROM tbl"); 2| while($row = mysql_fetch_array($sql, MYSQL_ASSOC)) { 3| mysql_unbuffered_query("DELETE FROM tbl2 WHERE 4| id=\"".$row["id"]."\""); 5| } If this works, change this bug to bogus. Previous Comments: ------------------------------------------------------------------------ [2002-03-27 09:30:40] [EMAIL PROTECTED] I try to put mysql_query everywhere (there are no mysql_unbuffered_queryies) Still the same. What's important? mysql_errno is always null and the error occures in various resources. Result of faulty operation in a database is sometimes ok and sometimes not. ------------------------------------------------------------------------ [2002-03-27 06:16:04] [EMAIL PROTECTED] Don't mix mysql_unbuffered_query and mysql_query. mysql_unbuffered_query is for fetching rows in SELECT, SHOW or DESCRIBE statements without buffering it. Use mysql_query ("DELETE ... instead. ------------------------------------------------------------------------ [2002-03-27 06:15:58] [EMAIL PROTECTED] Don't use mysql_unbuffered_query and mysql_query mixed. mysql_unbuffered_query is for fetching rows in SELECT, SHOW or DESCRIBE statements without buffering it.

It looks like php forget a resource link when calling other query (line 3). 1| $sql=mysql_query("SELECT id FROM tbl"); 2| while($row = mysql_fetch_array($sql, MYSQL_ASSOC)) { 3| mysql_unbuffered_query("DELETE FROM tbl2 WHERE id=".$row["id"]); 5| } When I first fetch all data to an array and then use them by the same way, it works. 1| $ARR=array(); 2| $sql=mysql_query("SELECT id FROM tbl"); 3| while($row=mysql_fetch_array($sql, MYSQL_ASSOC)) $ARR[]=$row; 4| foreach($ARR as $row) mysql_unbuffered_query("DELETE FROM tbl2 WHERE id=".$row["id"]); I can't find where is the problem. I try to put some sleep() after queries but nothing happens. ------------------------------------------------------------------------ [2002-03-26 18:38:18] [EMAIL PROTECTED] This SOMETIMES produces the error "3 is not a valid mysql resource on line 2" (or other numbers) First fetch_array is usually good.
