I just grabbed the 3.7.10 amalgamation source and built it, but have run into an issue where DISTINCT doesn't appear to actually return distinct values on a table that includes a UNIQUE clause. It unexpectedly returns duplicates instead.
My build environment is: - Mac OS X 10.6.8 - Xcode 3.2.5 - The source is built from within an Xcode project using LLVM GCC 4.2 - As mentioned above, I'm using the amalgamation source I found a fairly simple repro case using the shell tool (again, built by Xcode as above). % ./sqlite3 :memory: SQLite version 3.7.10 2012-01-16 13:28:40 Enter ".help" for instructions Enter SQL statements terminated with a ";" sqlite> CREATE TABLE t ( a INTEGER NOT NULL, b INTEGER NOT NULL, UNIQUE (a,b) ); sqlite> INSERT INTO t VALUES(1,1); sqlite> INSERT INTO t VALUES(2,1); sqlite> INSERT INTO t VALUES(3,1); sqlite> INSERT INTO t VALUES(2,2); sqlite> INSERT INTO t VALUES(3,2); sqlite> INSERT INTO t VALUES(4,2); sqlite> SELECT DISTINCT b from t WHERE a IN (1,2,3); 1 2 1 2 I obviously don't expect the duplicate results here. If you create the table without the UNIQUE clause, then the results are as expected (1 and 2 both only show up once). As a point of reference, the sqlite3 shell tool that ships with the OS (3.6.12) does produce the correct results. -- Steven Russell sruss...@extensis.com _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
