Cursor never stops
I appear to have made an error in this cursor and I can't seem to figure out what I have done wrong.
I've confirmed that the select pulls back 2 rows. But when I pass it into the cursor to pick appear the string and I can extract the exact value I need. The two rows look something like the following...
|DATAIDONTWANT|...|DATAIDONTWANT|<|1|DATAIDONTWANT|<|2|DATAIDONTWANT|...|
|DATAIDONTWANT|...|DATAIDONTWANT|<|1|DATAIDONTWANT|<|2|DATAIDONTWANT|...|
The cursor appears to grab the 1st row and continually loop around never getting onto the next row or end the program.
declare
@clobstringP varchar(max),
@clobstring varchar(max);
declare SevenCursor cursor for
select [value] as ClobP
from string_split(@clobstring, '>')
where value like '%<|2|%';
open SevenCursor;
fetch next from SevenCursor into @clobstringP;
while @@FETCH_STATUS = 0
begin
insert into [database].dbo.tablestuff ( ValueP )
select file387
from (
select
RowId387 = row_number() over( order by ( select 1 ) )
,file387 = [value]
from string_split(@clobstringP, '|')
) a
where a.RowId387 = 6;
end;
close SevenCursor;
deallocate SevenCursor;
Can someone point me in the right direction?

The cursor will loop infinitely unless and until @@fetchstatus = 0. In order to reach that state, you need to proceed through the dataset. In order to do that, you should add fetch next from SevenCursor into @clobstringP; to the inside of the begin ... end block so that the cursor has something to iterate over.
