Question

I’m trying to convert error messages held in a database table to user-friendly messages in a report.

I want to be able to replace the value in a field based on the literal text within another field.

The current query returns a dataset with three columns FileName, FileContent, CurrentDate:

SELECT 
    Left(Filename,Len(Filename)-16) as 'FileName',
    FileContent,
    Right(left(Filename, Len(Filename) - 8), 8) as 'CurrentDate'
FROM ErrorLogs 
WHERE 
     FileContent like '%Error%'
     AND Right(left(Filename, Len(Filename) - 8), 8) = 
             Replace(convert(varchar(10), getdate(), 102), '.', '')
ORDER BY 
    filename asc

For example if the file name is ExportFile, I want FileContent to read There was an error with the export file and if the file name is ImportFile I want FileContent to read accordingly.

Thank you in advance for your response…

You do not need temp tables to do this.

SELECT 
    Left(Filename,Len(Filename)-16) as 'FileName',
    FileContent = CASE 
         WHEN Left(Filename,Len(Filename)-16) = 'ABC' THEN 'File is FUBAR'
         WHEN Left(Filename,Len(Filename)-16) = 'XYZ' THEN 'File is hosed'
         ELSE 'File is good!'
    END,
    Right(left(Filename, Len(Filename) - 8), 8) as 'CurrentDate'
FROM ErrorLogs 
WHERE 
     FileContent like '%Error%'
     AND Right(left(Filename, Len(Filename) - 8), 8) = 
             Replace(convert(varchar(10), getdate(), 102), '.', '')
ORDER BY 
    filename asc
