Anonymous users2024-02-06A custom function that truncates the type of number in a string.
create function
no varchar(100)
returns int
as begin
while patindex('%[^0-9]%',@no)>0begin
set @no=stuff(@no,patindex('%[^0-9]%',@no),1,'')
endreturn convert(int,@no)end
As for how to format it, I believe you should be able to do it.

Can. The brackets match the ending number.

Anonymous users2024-02-04(?That's how it works, because in the matching character that you wrote, d only means one digit, and it can't show that it is a multi-digit, and adding a * or + can mean a multi-digit, and add another one? It's just that I add it habitually, to prevent greed, but there is no need to add it here either, because there will be no greed.

Well, positive assertions don't support repetition.

Anonymous users2024-02-02Principle: When the nth digit needs to be matched, (number + non-number) n-1 time + number, the last number is the result.
Extract the fourth digit (?:d+[^d]+)d+).3 = 4-1 of b
Extract the second number: (?.)d+[^d]+)d+).1 = 2-1 for b
If the above numeric extraction is a one-time match in one row, that. * b can be removed.
