title: mysql update REPLACE with concat
body: <p>my table save same ID like that : 123,9901,888,99</p>
  
  <p>I need change some id in this field </p>
  
  <p>I using my sql :  let 9901 change to 2001</p>
  
  <pre><code>UPDATE `TALBE_` SET id_group = REPLACE (id_group, '9901', '2001');
  </code></pre>
  
  <p>That's work</p>
  
  <p>but, I change 99 to 100</p>
  
  <pre><code>UPDATE `TALBE_` SET id_group = REPLACE (id_group, '99', '100');
  </code></pre>
  
  <p>My sql fidle had changed to</p>
  
  <p>123,<strong>10001</strong>,888,<strong>100</strong></p>
  
  <p>how to just change 99 -> 100, dont change 9901?</p>
  
  <p>Do I need use concat? </p>
  
  <p>But I test some time still cant do that</p>
