如何生成mysql查询一次插入2000条记录？

Question

这里是我的情况下，

我有表

ID(PK) TYPE(PK) 
01  3 
02  3 
03  3 
04  3 

现在我必须用3型插入ID高达1000 ... 没有任何选项可自动做到这一点???

Answer 1

不确定MySQL查询，但因为您熟悉PHP为什么不写一个非常简单的PHP脚本循环1000次，并插入..？

Answer 2

使用存储过程

DELIMITER $$ 

CREATE PROCEDURE insertMany(Pstart_id INT, Pend_id INT, Ptype INT) 
BEGIN 
    DECLARE i INT; 
    IF (pstart_id > pend_id) THEN BEGIN 
    SET i = PEnd_id; 
    SET Pend_id = Pstart_id; 
    SET Pstart_id = Pend_id; 
    END; END IF; 
    SET i = Pstart_id; 
    WHILE I <= Pend_id DO BEGIN 
    INSERT INTO table1 (id, `type`) VALUES (i, Ptype); 
    SET i = i + 1; 
    END; END WHILE; 
END $$ 

DELIMITER ; 

SELECT @first_id:= max(id)+1, @last_id:= max(id)+2001 FROM table1; 
CALL InsertMany(@first_id, @last_id, 3); 

这是因为你不发送通过网络1000个插入查询比使用PHP循环更快。

如果ID是一个数字：

INSERT INTO TableX 
    (ID, TYPE) 
VALUES 
    (1, 3) , 
    (2, 3) , 
    (3, 3) , 
    (4, 3) , 
    (5, 3) , 
    (6, 3) ; 

INSERT INTO TableX 
    (ID, TYPE) 
SELECT 
    ID, 3 
FROM 
    (SELECT 
     7+ d0.ID - 1 + (d1.ID * 6) - 6 + (d2.ID * 36) - 36 + (d3.ID * 216) - 216 
     AS ID 
    FROM 
     TableX AS d0 
     CROSS JOIN 
     TableX AS d1 
     CROSS JOIN 
     TableX AS d2 
     CROSS JOIN 
     TableX AS d3 
    WHERE d0.TYPE = 3 AND d0.ID <= 6 
     AND d1.TYPE = 3 AND d1.ID <= 6 
     AND d2.TYPE = 3 AND d2.ID <= 6 
     AND d3.TYPE = 3 AND d3.ID <= 6 
) AS tmp 
WHERE ID <= 1000 ;
