in reply to Insert BLOB into DB without using system memory, but using filehandle.

There is no standardized API for "streaming" blobs in and out of DBI handles, but DBD::Oracle does support it. See the LOBs and LONGs section of the DBD::Oracle interface.

[Corion]: GrandFather: Ah, (hardware) APIs - I have a similar situation with Chrome and its API... It is fairly underdocumented and I guess I have to hunt...
[Corion]: ... down supposedly working code to find out what I'm supposed to do
[GrandFather]: I haven't any "working code" to inspect! I have to find ways to generate reference signals then check the numbers I get at the far end match.
[GrandFather]: That's ok when the signal is a voltage, but there are three axis accelerometers, gyroscopes and magnetometers in these things! A little invention is needed at times!
[Corion]: GrandFather: Yeah, in that aspect, hardware is far more a black box than software
[GrandFather]: Oh, and the manufacturer tells lies too! I'm sure they don't mean to, but I know for sure some of the stuff they say is just wrong. It's possible they don't understand what we are asking, but that's not a good look either
[Corion]: GrandFather: Ah, unit testing hardware is fun, especially when the hardware is uncalibrated ...
[GrandFather]: Us: "What scaling do we need to apply to the numbers from the SDK for the wibble?". Them: "Oh, the numbers from the SDK for the wibble are already correct, they don't need scaling"
