If alphabetically Igor's solution works....but I'm not sure why you alphabetize singled query result like that. If you want the first ones inserted into the table try this: select * from table2 t1where t1.language = 'spanish' or not exists (select 1 from table2 t2 where t2.id = t1.id and (t2.language = 'spanish' or t2.rowid < t1.rowid)); For this data CREATE TABLE table2 (id integer, language text, title text, primary key (id, language)); INSERT INTO "table2" VALUES(1,'spanish','title1'); INSERT INTO "table2" VALUES(2,'english','title2'); INSERT INTO "table2" VALUES(3,'russian','title3'); INSERT INTO "table2" VALUES(3,'english','title3'); INSERT INTO "table2" VALUES(3,'spanish','title3'); INSERT INTO "table2" VALUES(2,'dutch','title2'); INSERT INTO "table2" VALUES(2,'danish','title2'); Igor's produces: 1|spanish|title1 3|spanish|title3 2|danish|title2 The rowid one produces: 1|spanish|title1 2|english|title2 3|spanish|title3 Michael D.
