Description
The grammar in sql_yacc.yy is conflicting in the grant_privileges rule.
- The keyword FUNCTION is not reserved in MariaDB, it's a valid a table name.
- The keywotd TABLE is optional in the ON TABLE syntax
So the sequence "ON FUNCTION" is ambiguous:
grant_privileges ON FUNCTION f1 TO foo@localhost; |
grant_privileges ON [TABLE] function TO foo@localhost; |
It can either be a ON FUNCTION or "ON TABLE function" with
Here's the bison -rall output:
222 sp_handler: . FUNCTION_SYM
|
223 | . PROCEDURE_SYM
|
224 | . PACKAGE_ORACLE_SYM
|
225 | . PACKAGE_ORACLE_SYM BODY_ORACLE_SYM
|
3405 grant_command: grant_privileges ON . opt_table grant_ident TO_SYM grant_l |
3406 | grant_privileges ON . sp_handler grant_ident TO_SYM grant_ |
3419 opt_table: . %empty [IDENT, IDENT_QUOTED, EMPTY_SYM, JSON_TABLE_SYM, IGN
|
3420 | . TABLE_SYM
|

|
PACKAGE_ORACLE_SYM shift, and go to state 2152 |
PROCEDURE_SYM shift, and go to state 2153 |
TABLE_SYM shift, and go to state 2154 |
FUNCTION_SYM shift, and go to state 2155 |
|
|
FUNCTION_SYM [reduce using rule 3419 (opt_table)] |
$default reduce using rule 3419 (opt_table) |
The same problem is also reported in the REVOKE grammar.
The opt_table rule should be resolve using %prec. It's empty branch should parse only if the following lookahead token is not FUNCTION_SYM.
