odbc_columns()

Hi. Have a question: I've tried using the odbc_columns() function to get a list of columns in an access database connected via an ODBC System DSN.. However, I haven't had much luck in trying to use it. The manual page doesn't really cover much about it, and I noticed a few comments posted there (on www.php.net) mentioning that it was a pretty badly documented function. In any case, there were notes on how to use it with MS SQL 7, but none on just plain access databases. All I want to get is a list of field names in a table. What would the proper syntax be to do that? Any help would be appreciated. Thanks, Scotty
