Eike,

I am with you - this feature request makes no sense.  What are you going to
do, create a INDEX on your LONG?

I would encourage anyone making this request needs to consider a general
purposes index service - like Microsoft Index Server or Altavista code.

It is my experience that these index servers are THOUSANDS of times faster
than any of the SQL Database engines I have worked with (including SAPDB).

http://www.microsoft.com/ntserver/techresources/webserv/IndxServ.asp

Microsoft's tool even supports a SQL syntax for doing searches.  It also
supports very complicated searches, where the LIKE interface for SQL is
often limited in the pattern matching it can do.

It is free as part of the base operating system.

There is also a OpenFTS (Open Full Text Search) project that uses PostgreSQL
as backend for the custom indexing.

Hi,

after some discussions internally now the question to the whole list:

LONG-columns cannot be used in WHERE-condition (except for IS
NULL-qualification). Some people ask for LIKE in LONGs or ask for '=' for
LONGs.

Do you really want LONG columns to be checked for LIKE (longcol LIKE
'abc*def', the star standing for 1.4325GB or so?) or do you need some longer
character values, may be up to 64 KB?

We here cannot imagine   unformatted    text with a length of more than
(let's say) 64KB.

Let us think of WORD-docs, but they are not unformatted and therefore
comparing will usually not return the wanted result.

It is easy to ask for this feature. It is not that easy to implement it. And
therefore we would like to know what you need. What you need, not what is
easy to write down without thinking about the usage, performance, ...

Thank you

Elke
