mysql中的正则表达式字符串替换

Question

Is there a simple way to do the following in mysql:

"Value ( some stuff here) " --> "Value"

Something similar to REPLACE("(*)","") ? How would I go about doing this and stripping the remaining whitespace?

Answer 1

Try:

"/s*/(.*/)/s*"

This will match leading whitespace, the text in parenthesis and trailing whitespace.

Look at UDFs(user defined functions). You'll want something like oracle's REGEXP_REPLACE

Answer 2

In mysql you cannot replace items of rows with regexp help. So you have to select all values "Value ( some stuff here) " from a defined column. Process them on a client-side with python facilities. After that you need update all rows in a mysql database.
