Returning a set datatype from MariaDB function












0















Given below is the syntax for the MariaDB's CREATE FUNCTION:



CREATE [OR REPLACE]
[DEFINER = {user | CURRENT_USER | role | CURRENT_ROLE }]
[AGGREGATE] FUNCTION [IF NOT EXISTS] func_name ([func_parameter[,...]])
RETURNS type
[characteristic ...]
RETURN func_body


func_parameter:
param_name type


type:
Any valid MariaDB data type


characteristic:
LANGUAGE SQL
| [NOT] DETERMINISTIC
| { CONTAINS SQL | NO SQL | READS SQL DATA | MODIFIES SQL DATA }
| SQL SECURITY { DEFINER | INVOKER }
| COMMENT 'string'


func_body:
Valid SQL procedure statement


The type parameter accepts any valid MariaDB data type. I tried to return a set:



delimiter //
create function get_a_set ()
returns set
begin
RETURN SET('a' , 'b');
end //

delimiter ;


But I am getting a syntax error in the following line: RETURN SET('a', 'b');



The exact error is given below:



ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'begin
RETURN SET('a' , 'b');
end' at line 3


Any help would be greatly appreciated. Thanks!
