... until the collector arrives ...

This "blog" is really just a scratchpad of mine. There is not much of general interest here. Most of the content is scribbled down "live" as I discover things I want to remember. I rarely go back to correct mistakes in older entries. You have been warned :)

We discovered a restriction in JDBC today.  The JDBC spec states that when reading columns from a row in a result set, the rows must be read left-to-right and no rows may be read twice.  The spec says that this restriction is for compatibility for some underlying databases.  Presumably, this restriction is in place so that a driver may use a stream to retrieve results, which makes a lot of sense when there is a prospect of BLOBs etc. in the result set.  This problem surfaced when Larry was processing metadata result sets from SQLServer.
