Question

列＆＃34;时间戳＆＃34; （table：rand_numbers＆＃34;）在每一行中都有相同的时间戳：
2016-09-26 00:00:13
2016-09-26 00:00:13
2016-09-26 00:00:13
2016-09-26 00:00:13

我想在每一行添加1分钟，结果是：
2016-09-26 00:00:13
2016-09-26 00:01:13
2016-09-26 00:02:13
2016-09-26 00:03:13

这不起作用：

CREATE PROCEDURE myproc()
BEGIN
    DECLARE i int DEFAULT 1;
    WHILE i <= 10 DO
        INSERT INTO rand_numbers (timestamp) 
         VALUES ('2016-09-26 00:00:13' + INTERVAL 1 MINUTE);
        SET i = i + 1;
    END WHILE;
END

Answer 1

只需使用循环插入

DELIMITER //
CREATE PROCEDURE myproc()
BEGIN
    DECLARE count INT DEFAULT 0;
    DECLARE max INT DEFAULT 10;

    WHILE(count < max) DO
        INSERT INTO rand_numbers (timestamp) VALUES ('2016-09-26 00:00:13' + INTERVAL count MINUTE);
        SET count = count + 1;
    END WHILE;
END//
DELIMITER ;

使用run call myproc();

Answer 2

试试这个

DECLARE @intFlag INT
DECLARE @VALUE DATETIME

SET @intFlag = 1
SET @VALUE = CURRENT_TIMESTAMP

--print @VALUE
WHILE (@intFlag <=5)
BEGIN
    PRINT (DATEADD(minute,1,@VALUE));
    SET @VALUE = (DATEADD(minute,1,@VALUE));
    SET @intFlag = @intFlag + 1
    CONTINUE;
END

MYSQL：为每一行添加一分钟到时间戳
