welder assembly Thursday, December 13 2007
Snow fell for much of the day, eventually accumulating to a depth of about a foot. It was a good day for sitting by the fire or (in my case) watching old episodes of MythBusters while putting together the fancy arc welder Gretchen bought me for Hanukkah. Most of the work involved attaching the enormous 240 volt plug (not supplied) to its power cable.
At other times I was working on a set of PHP functions that can parse information (particularly table names) out of a string of SQL, allowing a web page to do things like display links allowing for the editing of records returned by a raw SQL query. I can imagine there would be some uses for PHP SQL parsing, since it could allow a web server to anticipate the behavior of a query and act accordingly. Most of the time, of course, SQL is built from known tables and fields and parsing isn't necessary. But by the time the SQL reaches certain functions it has already been built, and I could see it being useful in some cases for those functions to deconstruct and interpret it.
