How do I search and replace using regex in MySQL?

I'm trying to update a field which contains HTML and I want to find all the rows that have forms in them and remove the form tags and anything in between them, however I'm running into problems with my select and the regex.

SELECT * FROM db.table WHERE body REGEXP "<form[^>].+?>.+?</form>";

and the error I g开发者_运维知识库et says: 'repetition-operator operand invalid' from regexp.

I was hoping to make that SELECT into a subselect for an update query but I'm stuck at this point.

I think your problem is in your form expression. Try the following:

"<form[^>]*>.+?</form>"

Remember that MySQL supports a limited set of regular expression matching and testing.
