MDB FireBird/InterBase driver

Notes:

  • when fetching in associative mode all keys are lowercased.
  • Currently, the driver relies on the Interbase server to use SQL dialect 3 that was introduced with Interbase 6. Some versions of Interbase server, like the Super Server, do not seem to work by default with dialect 3. This may lead to errors when trying to create tables using Interbase SQL data types that are only available when using this dialect version.
  • Interbase does not support per field index sorting support. Indexes are either ascending, descending or both even when they are defined from more than one field. Currently Metabase Interbase driver uses the index sorting type given by the first field of the index for which it is specified the sorting type.
  • The numRows method is emulated by fetching all the rows into memory. Avoid using it if for queries with large result sets.
  • Interbase does not provide direct support for returning result sets
  • Current Interbase versions do not support altering table field DEFAULT values and NOT NULL constraint. Text fields' length may only be raised in increments defined by Interbase, so the Metabase Interbase does not support altering text field length yet.
  • createDatabase and dropDatabase are not supported
  • MDB creates Interbase blobs before executing a prepared queries to insert or update large object fields. If such queries fail to execute, MDB Interbase driver class is not able to reclaim the database space allocated for the large object values because there is currently no PHP function to do so.
