更新MySQL字段;條件=兩個數字之間的字符串字段

Question

我想更新字段的值，如果字符串列在兩個數字之間。

UPDATE SAMPLE.EXAMPLE 
SET modNum = CONCAT(modNum,"26") 
WHERE modNum NOT LIKE '%26%' 
    AND (procKey BETWEEN 90000 AND 99123 OR procKey = 77444); 

不幸的是我得到一個錯誤：

Error Code: 1292. Truncated incorrect DOUBLE value: '4123F '

我很驚訝，因爲當我做了選擇，我得到預期的結果。

​​

CREATE TABLE語句：

'CREATE TABLE `example` (
    `id` int(11) NOT NULL AUTO_INCREMENT, 
    `modNum` char(4) DEFAULT NULL, 
    `procKey` char(8) DEFAULT NULL, 
    PRIMARY KEY (`id`) 
) ENGINE=InnoDB AUTO_INCREMENT=7 DEFAULT CHARSET=latin1' 

樣本數據：

INSERT INTO `SAMPLE`.`EXAMPLE` (`modNum`, `procKey`) VALUES ('42', '99001'); 
INSERT INTO `SAMPLE`.`EXAMPLE` (`modNum`, `procKey`) VALUES ('42', '9900f'); 

我能做些什麼來更新給我的條件列？

對我來說，它看起來像一個bug。我能想到的最好的方法是使用正則表達式來檢查procKey的值是否爲整數。我更改我的UPDATE語句爲：

UPDATE SAMPLE.EXAMPLE 
SET modNum = CONCAT(modNum,"26") 
WHERE modNum NOT LIKE '%26%' 
    AND procKey REGEXP '^[0-9]+$' 
    AND (procKey BETWEEN 90000 AND 99123 
     OR procKey = 77444); 

請讓我知道是否有更好的方法。

試試這個：

UPDATE SAMPLE.EXAMPLE 
SET modNum = CONCAT(modNUM,"26") 
WHERE modNum NOT LIKE '%26%' 
    AND (procKey BETWEEN 90000 AND 99123 OR procKey = 77444);

它爲我工作，所以我」敢肯定那一定是一些bug。
