Agreed, there have been higher priority items to be addressed before we
tackled this.

Firebird v2.0 allows for indexes to be defined based on expressions.
Thus you will be able to define an index on "UPPER( Field_NAME)" and
have the system use the index as appropriate.

This has been discussed and there are a number of semantic issues
related to using Domains.

Domains support a larger definition than 'simple' data type, such as
default and check/constraints. Are these 'extended properties' to be
applied each time a SP is called?

Additionally, Domains can be ALTERed. What is the impact of ALTERing a
Domain on the related SPs?

Please provide an example.

Since you have already responded separately that this is a performance
related issue, I will point out that v2.0 has:

- a completely new ODS (On Disk Structure) for indexes, which
- implements a new compression algorithm
- significantly reduces the overhead of poorly selective indexes
(a lot of duplicates)
- increases the max size of an index
- adds selectivity for segments of multi segment indexes

- a significant revision to the optimizer

With all of this, index handling and performance is at least an order of
magnitude better (from my own testing)


> 7. Export DUMP options to SQL statements, XML, etc

There are already a number of third-party tools (free) which do this.
Why would the project 're-invent the wheel'?
