Error when calling SQL - Resource id #237

[PlymWS]

I've tried to perform an extra SQL query on the index page.  I know the SQL syntax is correct but the command outputs the error message Resource id #237

What does this mean and how would I fix the SQL query or php to correctly echo the result of the query ?

Thanks for any help.

For a start post your code. The message seems to indicate you are attempting to display a resource instead of some actual data.
