Question

i had query for update the version of my value, here the code

DECLARE @inParam AS VARCHAR(50) = '80003689_CST_20120118'
DECLARE @file_extension varchar(50)='.xlsx'
DECLARE @lastVer AS VARCHAR(50)
DECLARE @nextVer AS INT 
DECLARE @combine AS VARCHAR(50) 

SELECT @lastVer = MAX([File_Name]) 
  FROM dbo.Uploaded_File 
 WHERE [File_Name] LIKE @inParam+'%'

SELECT @nextVer = CAST(SUBSTRING(@lastVer,LEN(@inParam) + 6, 1) AS INT) + 1

SELECT @combine = @inParam + '(' + CONVERT(VARCHAR, @nextVer) + ')' + @file_extension

SELECT @lastVer, @nextVer, @combine

the problem is when the value 80003689_CST_20120118(1), its not updated the version, the result i had 80003689_CST_20120118(1)(1)…

but i wanted the result become 80003689_CST_20120118(2).

so if i had same value it will become :

80003689_CST_20120118
80003689_CST_20120118(1)
80003689_CST_20120118(2)

etc

I think it works now:

DECLARE @inParam AS VARCHAR(50) = '80003689_CST_20120118'
declare @file_extension varchar(50)='.xlsx'
DECLARE @lastVer AS VARCHAR(50)
DECLARE @nextVer AS INT 
DECLARE @combine AS VARCHAR(50) 

SELECT @lastVer = MAX(CAST(SUBSTRING([File_Name], LEN(@inParam)+2, LEN([File_Name]) - LEN(@inParam) - 2) AS INT))
FROM dbo.Uploaded_File 
WHERE [File_Name] LIKE @inParam+'(%)'

SELECT @nextVer = ISNULL(@lastVer, 0) + 1
SELECT @combine =  @inParam + '(' + CONVERT(VARCHAR, @nextVer) + ')' + @file_extension
SELECT @lastVer,@nextVer,@combine
