URL: https://dev.monetdb.org/hg/MonetDB?cmd=changeset;node=e32e70fa2fbe
Modified Files:
sql/backends/monet5/rel_bin.c
sql/server/rel_unnest.c
Branch: default
Log Message:
fixes for 2 more sqlancer issues,
1) in handle_in_exps make sure we have a 'bat' for 'select' (ie reduce)
expressions
2) make sure we do not see 0.2 = 0.3 as true, ie if only right could be
seen
as true, the expression may still be false or nil.
