Error Handling with Batch File & Sqlcmd

Question

I have a batch file that runs some SELECT queries using sqlcmd, puts the results into text files, and uploads those files onto an FTP server. That\'s all working just the way it

Answer 1

I built a minilanguage in python to solve a similar problem. Using the subprocess library, you can run your code through sqlcmd, then get the output and any error codes. Parse the output before putting it into your text file, and if necessary go through error repair states. These states can modify the code or options and retry sending them through sqlcmd. If all else fails, email a human.

Of course, since I was using python like that, I didn't bother with sqlcmd at all and just used the odbc python libraries for a direct connection to the database. I could rollback my transactions if I had a catastrophic failure, run it in interactive mode, or via a command file etc. etc.

That's a pile of work though. For more simplistic error checking, just add a filter to your pipeline, say grep or awk. Or roll your own with flex.
