Danijel (nice picture, by the way)

I've found it's useful from a debugging standpoint to divide my strings into FIELDS, TABLES, FILTER and ORDER clauses, so the SQL looks like

SELECT &cFields from &cTables;
WHERE &cFilter into cursor MyCursor ordered by &cOrder

Much simpler to handle it all.

>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 + "SomeFields" + " FROM "
>lcSel = lcSel + "SomeTables" + " WHERE "
>lcSel = lcSel + "Condition"
>&lcSel
>I do it that way and it works great.
