In this appendix we hope to give you a flavour of the functionality and quirks of the different DBI drivers and their databases.
The line between the functionality and quirks of a given driver and the functionality and quirks of its corresponding database is rather blurred. In some cases the database has functionality that the driver can't or doesn't access, in others the driver may emulate functionality that the database doesn't support, like placeholders. So when you see the terms driver or database below, take them with a pinch of salt.
Our primary goals are to:
We don't attempt to describe the drivers and database in detail here, we're only interested in the key features that are most commonly used or relevant to our goals. And for those features we're just providing an outline guide. Sometimes little more than signposts. Consult the database documentation for full details.
With the cooperation of the driver authors we have produced descriptions for the following drivers and databases:
For each of these drivers we've tried to cover the same range of topics in the same order. The topics include:
Reading straight through is not for the faint hearted. We recommend dipping in on an as-needed basis.
