SQL Query:
SELECT CASE WHEN c>(SELECT avg(c) FROM t1) THEN a2 ELSE b10 END FROM t1;
causes assertion failure
Reproducible: Always
Steps to Reproduce:
Start mserver5 (MonetDB 5 server v11.19.9 "Oct2014-SP2")
Start mclient
execute SQL commands:
CREATE TABLE t1(a INTEGER, b INTEGER, c INTEGER, d INTEGER, e INTEGER);
INSERT INTO t1(e,c,b,d,a) VALUES(103,102,100,101,104);
SELECT CASE WHEN c>(SELECT avg(c) FROM t1) THEN a2 ELSE b10 END FROM t1;
Actual Results:
builtin opt gdk_dbpath = /export/scratch1/dinther/Downloads/INSTALL/var/monetdb5/dbfarm/demo
builtin opt gdk_debug = 0
builtin opt gdk_vmtrim = no
builtin opt monet_prompt = >
builtin opt monet_daemon = no
builtin opt mapi_port = 50000
builtin opt mapi_open = false
builtin opt mapi_autosense = false
builtin opt sql_optimizer = default_pipe
builtin opt sql_debug = 0
cmdline opt gdk_debug = 10

Fixed (properly pass all projection expressions) and added test

Reopened because when I extend the SELECT query with "abs(b-c)" as in:
SELECT abs(b-c), CASE WHEN c>(SELECT avg(c) FROM t1) THEN a2 ELSE b10 END FROM t1;
or
SELECT CASE WHEN c>(SELECT avg(c) FROM t1) THEN a2 ELSE b10 END, abs(b-c) FROM t1;
I again get the assertion failure:
mserver5: ../../../../MonetDB-11.19.11/sql/backends/monet5/rel_bin.c:2279: rel2bin_project: Assertion `0' failed.
This happens on MonetDB 5 server v11.19.11 "Oct2014-SP3" and on MonetDB 5 server v11.20.0. (built on 28 may 2015).
On MonetDB 5 server v11.20.0 I get:
mserver5: ../../../../dev/sql/backends/monet5/rel_bin.c:2352: rel2bin_project: Assertion `0' failed.
I have extended BugTracker-2015/Tests/case_aggr.Bug-3705.sql and stable.out with the new SELECT statements and desired output.
