Let me explain. I have a routine that using CA object - WITHOUT CursorSchema - that can be used to SQL Select from any table. So I jused the above SQL Select expression (e.g. select * from information_schema.....) but it returned not a table of of rows where each row is a column name but instead a table of no rows with column names as column names in the MyTable. I thought that the SQL Select from VFP should also return a table of similar structure and number of rows as I get in SQL Server SMMS.
