Things I hate, an incomplete list:
x. intermittent database errors that relate to where the data comes from before it gets to the database, not the specific database I'm querying
x+1. intermittent errors that stop happening after I report them to the IT people responsible for the relevant database.
also, scripting that doesn't appear to have errors but obviously does because it isn't working. Presumably a comma in the wrong place
x+lots. commas
