Answer 1

• 更改DELIMITER
• 使用SET

查询，

DELIMITER //
CREATE  FUNCTION get_audit_id
(
    p_pubco_id INT, 
    p_audit_id INT, 
    p_fiscal_date DATE
) 
RETURNS INT
BEGIN 
    DECLARE t_new_id INT;

    IF p_pubco_id = 0 or p_audit_id = 0 THEN    
        SET t_new_id = -1;
    ELSE
        SET t_new_id = (SELECT audit_id
                        FROM a_audit_reg 
                        WHERE p_pubco_id = a_audit_reg.pubco_id
                            and p_audit_id = a_audit_reg.audit_id
                            and p_fiscal_period = a_audit_reg.fiscal_period_date);

        IF found_rows() = 0 then
            insert into a_audit_reg (pubco_id, audit_id, fiscal_period_date)
            values (p_pubco_id, p_audit_id, p_fiscal_date);

            SET t_new_id = last_insert_id();
        end if;
    end if;
    return t_new_id;
END //
DELIMITER ;
