Hi All,

I ave a Problem with the '==' Operator in the SELECT SQL.

My problem is, I have somewher a filter that is set like
SET FILTER TO Field==myVal
EXACT is OFF, ANSI is OFF

Now I need to create a SQL SELECT that holds the same records as the filtered table.

if I use something like
lcWhere = IIF(EMPTY(FILTER(),'','WHERE '+FILTER())
SELECT *;
 FROM MyTable;
 &lcWhere
This gives possibly different results because the "==" Operator is differnt for SELECT SQL and any other place.

So I'm thinking about, but could not find a good solution. Replace '==' with "=" and SET ANSI ON will mix up all original "=" statements.
Using LIKE(MyVal,Filed) works fine - until somebody adds a wildcard to the myVal ...

I run out on ideas on this.

Please help me
