>This kind of error happen when you have and invalid query . >Remember that table names and field names are case sensitive, keywords not. Having been a *nix admin of one variety or another since '94, I figure EVERYTHING'S case-sensitive (except me, I'm not being touchy, honest). :) And as a matter of habit I keep everything lower-case when I'm working with file names and stuff in the shell. Helps me type faster. That's not the problem here, I'm positive. I can cut-and-paste the query into the MySQL interface and boom I get three rows. >If the name of your table "mytable" or the field "name" are not exactly the >query fails and $result will be null (0) and generate the error : "Supplied >argument is not a valid MySQL result resource..." when you attempt to use >$result as an argument to php functions. >Try this: >$result = mysql_query ("Select name from mytable") or die(mysql_error()); >if($result){ > while ($row = mysql_fetch_array ($result)) { > $newTableName = $row['0']; > $sSQL = "Select id,thread,subject,author,datestamp from >$newTableName order by datestamp desc limit 30"; > } >} Yup, did that on another list member's suggestion and indeed the query is returning zip. WHY is the question!! There is data in the table, the query is formed correctly, I absolutely positively know there is a data connection to the server, other material from the same database displays flawlessly on the same page at the same time as this one fails, if I make the query by hand using the exact same letters in the exact same order it works. aagh! I'm sure I have to be doing something wrong, but what? In the words of Spike Jones, "it's driving me sane!" Thanks for the help, guys.
