MDEV-20021 sql_mode="oracle" does not support MINUS set operator

MINUS is mapped to EXCEPT

diff --git a/sql/sql_yacc.yy b/sql/sql_yacc.yy index 57ba9df42c0..edd2f353dd0 100644 --- a/sql/sql_yacc.yy +++ b/sql/sql_yacc.yy @@ -16037,6 +16038,7 @@ reserved_keyword_udt_not_param_type: | MINUTE_MICROSECOND_SYM | MINUTE_SECOND_SYM | MIN_SYM + | MINUS_ORACLE_SYM | MODIFIES_SYM | MOD_SYM | NATURAL

this is not good. MINUS should be in reserved_keyword_udt_not_param_type only in oracle mode, and otherwise it should be in keyword_sp_var_and_label (or not a keyword at all, but I don't think it's possible). Regards, Sergei VP of MariaDB Server Engineering and security@mariadb.org
