我正在尝试使用以下参数和值更新一个充满url对象的longtext列：
UPDATE table SET column = REGEXP_REPLACE(column,'tid4=[a-z]+','tid4=NEW_VALUE');
这将清空包含参数的单元格，而不是替换该单元格中所有出现的参数，无论该值是多少（只要按字母顺序排列）都使用与我设置的值相同的参数即可。有什么想法我做错了吗？如何替换整个单元格中所有出现的字符串？
谢谢！

示例单元格内容：

我必须使tid4=whatevervalue的所有出现都变成tid4=thesamevalue。
我还有其他要替换的东西，例如.php?tid1= to .php?subid=&tid1= then this to .php?sub_id=newvalue&tid1=
等
