T-SQL - Remove everything before and after in a string - sql

Question

Please assist me with the SQL query shown below.
This is the error I get:
System.Exception: TransformerException ---> Library.Utilities.TransformerException: Transformer transforming [0000000000085153227:documentId] using [4:transformId] with time remaining [00:00:54.4517645:TimeSpan] output document is [0000000000085153231:documentId] ---> and so on...
I'm training to retrieve this value 85153227 only.
Please assist
SELECT
SUBSTRING(message, 0, CHARINDEX('System.Exception', message)) + ' ' +
CASE
WHEN CHARINDEX('Transformer transforming [', message) > 0
THEN SUBSTRING(message, CHARINDEX('[',message), LEN(message)-CHARINDEX('[', message))
ELSE ''
END
FROM
dbo.Documents
Thank you

Answer 1

DECLARE # AS VARCHAR(MAX)=
'System.Exception: TransformerException ---> Library.Utilities.TransformerException: Transformer transforming [0000000000085153227:documentId] using [4:transformId] with time remaining [00:00:54.4517645:TimeSpan] output document is [0000000000085153231:documentId]'
SELECT
CAST(
SUBSTRING(#,
CHARINDEX('Transformer transforming [',#,0) + LEN('Transformer transforming [')
, CHARINDEX(':documentId]',#,0) - ( CHARINDEX('Transformer transforming [',#,0) + LEN('Transformer transforming [') ))
AS BIGINT)
--OUTPUT
--------------------
85153227

It's hard to determine an exact response to this because you did not identify if the exception is always structured the same. With what is provided, this is what I would do.
Removing the leading string of characters with STUFF; STUFF([Message], 1, CHARINDEX(N'Transformer transforming [', [Message]) + 25, N'')
Then assuming that the string of characters with the number is 19 characters long, I then do a SUBSTRING to find the first non-zero character. SUBSTRING({field}, PATINDEX('%[^0]%', {field} + '.'), LEN({field})) substituting step 1 into this string for {field} (I tried to simplify the code here).
Here is the SQL statement showing this.
IF OBJECT_ID(N'tempdb..#t') IS NOT NULL DROP TABLE #t
SELECT CAST('System.Exception: TransformerException ---> Library.Utilities.TransformerException: Transformer transforming [0000000000085153227:documentId] using [4:transformId] with time remaining [00:00:54.4517645:TimeSpan] output document is [0000000000085153231:documentId] ' AS NVARCHAR(MAX))
AS [Message]
INTO #t
SELECT *,
STUFF([Message], 1, CHARINDEX(N'Transformer transforming [', [Message]) + 25, N'') AS BeginningCharactersStripped,
SUBSTRING(LEFT(STUFF([Message], 1, CHARINDEX(N'Transformer transforming [', [Message]) + 25, N''), 19), PATINDEX('%[^0]%', LEFT(STUFF([Message], 1, CHARINDEX(N'Transformer transforming [', [Message]) + 25, N''), 19) + '.'), LEN(LEFT(STUFF([Message], 1, CHARINDEX(N'Transformer transforming [', [Message]) + 25, N''), 19)))
AS Number
FROM #t
WHERE [Message] like N'%Transformer transforming [[]%'

Answer 3

Based on what you provided I modified your query a bit to get the output you want. You may need to adjust depending on your data.
SELECT substring(message,0,charindex('System.Exception',message)) + ' ' +
CASE WHEN charindex('Transformer transforming [',message) > 0
THEN Convert(Varchar(8000), Convert(BigInt, Substring(message,charindex('[',message) + 1, charindex(':documentid]',message)-(CharIndex('[',message)+1)))) ELSE '' END
FROM dbo.Documents

Answer 4

You can try this:
with MsgWithZeroesTbl as
(SELECT 'System.Exception ' +
CASE
WHEN charindex('Transformer transforming [',message) >= 0
THEN substring(message,charindex('[',message) + 1, charindex(':',message, charindex('[',message))- (charindex('[',message) + 1)) ELSE ''
END as MsgWithZeros
FROM dbo.Documents )
Select substring(MsgWithZeros, patindex('%[^0]%',MsgWithZeros), 10) from MsgWithZeroesTbl

Answer 5

I came up with:
DECLARE #string varchar(8000) =
'System.Exception: TransformerException ---> Library.Utilities.TransformerException: Transformer transforming [0000000000085153227:documentId] using [4:transformId] with time remaining [00:00:54.4517645:TimeSpan] output document is [0000000000085153231:documentId] --->'
SELECT cast(substring(#string, p1.p, p2.p-p1.p) as bigint)
FROM (VALUES (patindex('%[0-9]%', #string))) p1(p)
CROSS APPLY (VALUES (charindex(':', #string, p1.p+1))) p2(p);
Output:
85153227
