Hi Cetin,

this depends on the point of view. SET FILTER works perfectly - in his rules, because it depends on FoxPro's nativ operator "==".

SELECT SQL defines his own operator "==".

There is no problem that something is 'wrong'. It is clearly documented as it is.

My problem is how to translate the statement from FILTER() or the statement I put into a SET FILTER in a way that a SELECT SQL produces the same result as the filtered part of the cursor shows.

(Or what will do same: How to translate the statement out of SELECT SQL's WHERE clause in a way that SET FILTER TO displays the same result as SELECT SQL?)
