Try issuing select @@sql_max_join_size
And also make a product from the number of rows from all the tables involved in the join (with WHERE clause applied) and if it exceeds the number given from the select I gave you above... then that's your reason ! Also bare in mind that although you only request 30 rows with LIMIT... MySQL will still JOIN the tables... the LIMIT clause is applied just before sending the resultset to the client ! If you can't do it otherwise try setting a higher "sql_max_join_size"... or try using some temporary tables ! Good fortune ! -- Gabriel PREDA Senior Web Developer
#1104 - The SELECT would examine more rows than MAX_JOIN_SIZE. Check your WHERE and use SET SQL_BIG_SELECTS=1 or SET SQL_MAX_JOIN_SIZE=# if the SELECT is ok
