>SQL select can go up to 2000+ characters, but you should probably build up a text-string variable instead of merging and compiling a .prg. It will perform better as well. Ex.:
>lcSel = "SELECT "

>lcSel = lcSel + "SomeTables" + " WHERE "
>lcSel = lcSel + "Condition"
>&lcSel

Method suggested by Danijel is best.
That's the best way to go for any SQL statement.It not only provides a more than 255 characters SQL but also a flexibility to build any conditions and select tables at runtime as per the choice of user.
