ROW keyword mandatory (although it's optional in SQL-99).
mysql-test/r/row_test.result:
New results with the ROW syntax.
mysql-test/t/row_test.test:
Updated tests to use the ROW keyword.
sql/sql_yacc.yy:
Fixed ambiguity between the row value syntax and INTERVAL syntax by making the
ROW keyword mandatory (although it's optional in SQL-99).
The real problem might actually be INTERVAL, where the two rules
"INTERVAL_SYM expr interval '+' expr" and
"INTERVAL_SYM '(' expr ',' expr_list ')'" caused 40+ reduce/reduce conflicts
with the rows value syntax.
So possibly, the INTERVAL syntax should be fixed instead...
