regex for a string ,\"16 questions\", -


i not in regex , spent time figure out how search below pattern:

,\"16 questions\",

this constructed .\"[0-9,]+ questions\".
think close not sure how much. can please correct it. numeric value can have comma in when number crosses 1k. e.g 2,500 questions.

,"\d{1,3}(,\d{3,3})*\squestions?",

explanation:

  • \d{1,3}= 1~3 decimal digits
  • (,\d{3,3})* = comma , 3 decimal digits, whole group repeating 0~n times
  • \s = whitespace
  • s? = letter s can missing

these 2 parts give accurate recognition of possible numbers.

▶ test , visualization.

if backslashes in text true backslashes, regex including them be

,\\"\d{1,3}(,\d{3,3})*\squestions?\\",

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
