从长字符串的中间提取字符串 - SQL

Question

I have a table which has a column with a long string, i'm tasked with parsing an ID from the string, i've gotten to the point where I can extract everything after a delimiter string, but my query is still catching everything after the delimiter string, which I don't need.

There are records where have multiple ID's on the same line that I need to separate and capture as well.

I've included the SQL fiddle:

For some reason on the live data, when I use the query I have provided, it doesn't always capture the account number.

Here is an updated SQL Fiddle to show the new problems I'm running into. Updated FIDDLE

Answer 1

This returns the account numbers in the data:

select s.value
from temp t CROSS APPLY
     (VALUES (STUFF(description, 1, CHARINDEX('Account Attached: ', description) + LEN('Account Attached: '), '')
             )
     ) v(aa) CROSS APPLY
     STRING_SPLIT(LEFT(v.aa, CHARINDEX('Next Steps:', v.aa) - 2), ' ') s;

Here is your SQL Fiddle.
