I agree. Especially when creating stored procedures. In VFP code (that works with SQL Server tables) I can still use a lot of xBase language but in stored procedures it has to be all SQL commands.

I am using Cursor Adapter as a method of getting/setting SQL Server tables. From the stand-point of efficiency of SQL Server, is it better to get all records/rows of the table, scan thorugh all rows of the cursor, update the values, and then do TableUpdate() for all rows? Or process one row at a time and call TableUpdate() after each row is processed (columns updated).
