of a table? Does anyone know how this is queried in 7.3?

It isn't well documented, and not convenient to use, but see
array_dims() function on this page:
http://www.postgresql.org/docs/7.3/i...ve/arrays.html

Array support and documentation is significantly better in 7.4.x.

It is well-documented that if on a page there are several radio- buttons with the same name these are addressed as an array (and act collectively). Someone (LRN?) recently wrote about another case where name-match implies array addressing. It therefore occurred to me to try the following crude Web page : <head></head><body>

We have DB2 UDB v8.1 fixpak3 on AIX 5. Production and Development configuarations (at least for DB2) are identical albeit production is a 2-way server while development has only one processor.

Yet, on a given query (with 4 tables joined), it took 30-50 times longer to run in prod than on development....

We are migrating a customer from Version 7.1 FP3, to Version 8.2 (8.1 FP8). For the most part, things are faster, but there is one query that is much much slower, and it is a query that is used all the time. select ATTR1,ATTR2,ATTR3,ATTR4 from physical.part_list where S_PART_NUMBER like '%KJS%' The widlcard before and after seems to be hosing it, but for this particular piece of the application, this type of query is neccessary.

I have a table with 50 fields that receive input depending on whether that input came in from a 'shaker' form or a 'conveyor' form. Input from the 'conveyor' form might populate 25 fields while input from the 'shaker' form will populate another 20-25 fields but not the same fields (however there are about 10 common fields to both). I'd thought about using two tables (one for 'conveyor' and the other for 'shaker') but thought I'd try just...
