SQLyog中DELIMITER执行存储过程时出现前置缩进问题的解决方法

-- 必须顶格写（无缩进）
DELIMITER //
CREATE PROCEDURE grant_role_to_all_users()
BEGIN
    -- 这里面的缩进不会影响执行
    DECLARE finished INTEGER DEFAULT 0;
    DECLARE user_host VARCHAR(255);
    
    DECLARE user_cursor CURSOR FOR 
        SELECT CONCAT('`',USER,'`@`',HOST,'`') 
        FROM mysql.user 
        WHERE USER NOT IN ('root','mysql.sys','mysql.session','mysql.infoschema');
    
    DECLARE CONTINUE HANDLER FOR NOT FOUND SET finished = 1;
    
    OPEN user_cursor;
    
    get_user: LOOP
        FETCH user_cursor INTO user_host;
        IF finished = 1 THEN LEAVE get_user; END IF;
        
        SET @grant_sql = CONCAT('GRANT "public_role" TO ', user_host);
