SQL?!? So unclean ;-)
Is adding the index using frontbase manager something that can be done
after a table is populated? Or will I need to export and re-import my
data? Sorry, I'm far from a database expert.

Hello,
I've populated my eo tables with data and my queries are VERY
slow. A table with about 7000 entries takes a couple minutes to
retrieve a single EO (i.e. row of data). I guessing I need to
tell the database (frontbase) that it needs to index on the
attributes (columns) that I commonly query on. I was wondering,
what is the usual way to do this? Can this be done from
EOModeler? I know this is probably a very basic (i.e. dumb)
question.
1. You can do it in FrontBase manager.
2. If you use Wonder and migrations you can use
table.addIndex(columnName)
where table is an ERXMigrationTable and columnName the name of the
column (not the name of the attribute).
3. I think there is a way of defining indexes in Entity Modeler,
but I never used that.
There is. I tried to use it once. It is not quite cooked yet. I
don't recall if it just needed plugin support or if the EOF part
itself needed a few more bits. It will be very nice once this is
all working.
I recently, er, migrated to Migrations. They are quite nice.
Before that I used an SQL script.
