Question

我想在phpmyadmin中执行一个循环，它在表中插入行。到目前为止，我有：

DELIMITER $$

DROP PROCEDURE IF EXISTS insert_my_rows()

CREATE PROCEDURE insert_my_rows()
BEGIN
DECLARE i INT DEFAULT 376;

WHILE i<405 DO
        INSERT INTO wp_term_relationships(object_id,term_taxonomy_id,term_order) VALUES (i,16,0);
        SET i=i+1;
END WHILE;
END $$

DELIMITER ;

CALL insert_my_rows()

有了这个，我收到一个错误：

#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'DELIMITER$$

DROP PROCEDURE IF EXISTS insert_my_rows()

CREATE PROCEDURE ins' at line 1

Answer 1

DROP PROCEDURE语句的语法不正确！

更改

DROP PROCEDURE IF EXISTS insert_my_rows()

到

DROP PROCEDURE IF EXISTS insert_my_rows;

Answer 2

您需要使用正确的分隔符结束语句。将END更改为END$$。

Answer 3

仅在制作语句块时才必须更改定界符，因此在过程定义期间必须如此。 DROP PROCEDURE和CALL语句也需要定界符。

DROP PROCEDURE IF EXISTS insert_my_rows;

DELIMITER $$

CREATE PROCEDURE insert_my_rows()
BEGIN
    DECLARE i INT DEFAULT 376;

    WHILE i<405 DO
        INSERT INTO wp_term_relationships(object_id,term_taxonomy_id,term_order) VALUES (i,16,0);
        SET i=i+1;
    END WHILE;
END $$

DELIMITER ;

CALL insert_my_rows();

DROP PROCEDURE IF EXISTS insert_my_rows;
