[英]Regex to match all words in qoutes
我正在尝试编写正则表达式来匹配作为sql过程调用的参数传递的所有单词。
输入ex:
exec GetNextSequence 'abc', @brokerId out, 'fds'
insert into [ttt](id, code, description, startDate, endDate)
values (@bid, @code, @code, getdate(), '099999')
....
所以我需要得到'abc'和'fds'。
你能帮我写一下正则表达式,让它们介于“EXEC(UTE)?”之间吗? 和第一个关键字? 我拥有的关键字列表,所以如果你帮我使用INSERT就可以,我会替换它。
这个正则表达式将执行以下操作:
exec
关键字后第一行上的所有引用单词 笔记
insert
作为锚点。 考虑这个字符串边缘情况: exec GetNextSequence 'abc', @Insert, @brokerId out, 'fds'
(?<=^exec.*?)
假设您正在使用.net Regex引擎,因为许多语言不支持lookbehinds中的重复字符。 正则表达式
(?<=^exec.*?)'((?:(?!'|\n).)*)'
