正则表达式到 SQL 查询中的 select 列名

Question

I have a regexp that selects the columns from SQL query: \bwf\.[^,|^\s|^)]*

So from both queries

SELECT (wf.Name,
       wf.Status)

SELECT wf.Name, wf.Status

it will return "wf.Name" , "wf.Status" . But also I want to cover case when column contains round brackets:

SELECT (wf.Name,
       wf.Status())

regexp should return "wf.Name" , "wf.Status()" .

I tried to do it through non-capturing group (?:(?,\s|.|<statement>).)* but without success.

You can use

\bwf(?:\.\w+)+(?:\(\))?

See the regex demo . Details :

• \b - a word boundary
• wf - a wf string
• (?:\.\w+)+ - one or more repetitions of a . and one or more word chars (?:\(\))? - an optional occurrence of a () substring.
