Changeset: 6dad46a0dc4e for MonetDB
URL: http://dev.monetdb.org/hg/MonetDB?cmd=changeset;node=6dad46a0dc4e
Modified Files:
sql/server/sql_parser.y
Branch: sciql
Log Message:
Disable the alternative '(' scalar_exp_list ')' in value_exp,
which looks redundant.
I don't see the need to have this rule added.
It conflicts with the alternative '(' search_condition ')' in
simple_scalar_exp, and it causes the SQL query
"insert into t2 select (x - y)/3 from t1;" to produce incorrect result.
