There's is a limit of 10 tables per SQL Select. Take a look at Message #56131.

>Hi all,
>In a SQL SELECT command using 11 Tables I have 10 LEFT JOINS and
>1 INNER JOIN, but VFP returns a error message: TOO MANY SUBQUERIES.
>
>I'm not using Query Builder, and there arent Subqueries in the Command.
>If I use only 10 Tables it Works fine!
>
>Is there a restriction of how many Tables I can use in a SQL SELECT command
>in VFP, I searched all the documentation and havent found any mention
>that VFP handles only 10 Tables.
>
>Is there a workaround ?
>
>Thanks in Advance
