Thanks, here is the version with proper key words and a new question. The aim of all this is: To filter data by singer with the max datestamp lower or equal a given date. [CODE] DROP TABLE 'tblZO_Haupt'; CREATE TABLE 'tblZO_Haupt' ('id' INTEGER PRIMARY KEY, 'zo_tblEnsemble' INTEGER, 'zo_tblSaenger' INTEGER, 'zo_tblStueck' INTEGER, 'zo_tblStimmbez' INTEGER, 'datum' TEXT); INSERT INTO "tblZO_Haupt" VALUES(1,1,1,1,11,'2009-08-01 00:00:00'); INSERT INTO "tblZO_Haupt" VALUES(2,1,2,1,11,'2009-08-01 00:00:00'); INSERT INTO "tblZO_Haupt" VALUES(3,1,1,1,20,'2009-08-05 00:00:00'); INSERT INTO "tblZO_Haupt" VALUES(4,1,2,1,20,'2009-08-05 00:00:00'); INSERT INTO "tblZO_Haupt" VALUES(5,2,1,2,11,'2009-08-01 00:00:00'); INSERT INTO "tblZO_Haupt" VALUES(6,2,1,2,20,'2009-08-05 00:00:00'); -- Version #1 INSERT INTO "tblZO_Haupt" VALUES(7,2,1,2,14,'2009-08-02 00:00:00'); INSERT INTO "tblZO_Haupt" VALUES(8,2,2,2,14,'2009-08-02 00:00:00'); -- Version #2 -- INSERT INTO "tblZO_Haupt" VALUES(7,2,1,2,14,'2009-08-02 00:00:00'); -- INSERT INTO "tblZO_Haupt" VALUES(8,2,2,2,14,'2009-08-02 00:00:00'); SELECT * FROM tblZO_Haupt AS hpt WHERE hpt.datum = ( SELECT MAX(hpt_sub.datum) FROM tblZO_Haupt AS hpt_sub -- WHERE hpt_sub.id = hpt.id WHERE hpt_sub.zo_tblSaenger = hpt.zo_tblSaenger AND hpt.zo_tblEnsemble = 1 AND hpt.zo_tblStueck = 1 AND hpt_sub.datum <= '2009-08-02 00:00:00'); [/CODE] In version #1 there are no result. In version #2 (if I commented out the two lines) there is a result: 1|1|1|1|11|2009-08-01 00:00:00 2|1|2|1|11|2009-08-01 00:00:00 I don't understand what happens here. Any ideas?
