Hi List, I encountered a situation in which sqlite does not understand to which field I try to refer. I simplified the original query to show the problem. The simplified query itself is now completely meaningless (and for my specific situation I could rewrite the query to work around the problem).
In the example below I expected that mytable.myfield2 in the EXISTS expression would refer to myfield2 of table mytable from the top level UPDATE statement. It looks like the combination of an ORDER BY and an EXISTS that refers to the table of an UPDATE statement causes sqlite to report that myfield2 is unknown. Sqlite does not complain when I use mytable.myfield2 in other places in the query. CREATE TABLE mytable ( myfield1 INTEGER, myfield2 INTEGER ); UPDATE mytable SET myfield1 = (SELECT 1 ORDER BY EXISTS (SELECT 1 WHERE mytable.myfield2 =1 ) ); Error: no such column: mytable.myfield2 Tested with sqlite versions 3.8.4.3, 3.8.8.2, 3.11.1 and 3.15.0 (latest).
