I have an Access database with 58 fields in one table. I wrote many
of the field names so that they were descriptive so that others could
figure it out in the future. As an example, one field name is called
MissingPart1499 0aDescribe.
Should I be worried about the length of the field name? I'm expecting
about 20,000 records a year to be entered into the database. So, five
years from now, which would be about 100,000 records, will the
query.asp for a list of records be slow due to field name size? BTW,
the query.asp would just show a list of the last 3 months worth of
records and only a snapshot of about 6 of the 58 fields.
TIA

ynott,
Its a very bad idea to add extra columns just for description, Just create a
readme.txt instead were you describe your tables. Else you'll end up with a
really big database with unnecessary information.
columns, not fields.....
Never list more than 100 in a page...... use paging if needed...... and if
your database is going to be that large you might consider using SQL Server
instead.

Records have fields, HTMLtables have rows and columns, Database tables
are a random collection of records, and because of the randomness the
records shouldn't be called rows.

No, the length of the field names should have nothing to do with the speed
of a query. You are increasing the size of the metadata (the description of
the data, technically: "data about data"), which will increase the amount of
network traffic and the amount of resources used to create the recordset to
contain this data. But this will not be dependant on the number of rows in
your table, and with proper bandwidth and good programming techniques, will
not be likely to cause any performance problems.
I'm more concerned about the possibility of bad database design here. What
is the meaning of the "14990a"? It makes it appear as if you are storing
data in your metadata: never a good idea.

Bob, I am not going to play the "I am right, you are wrong" game.
Evertjan.
P.S.:
I am right, as long as we are talking 4th generation datavases:
The word "row" implies order. [btw: as do "columns"]
If there are rows, there must be a front row and a back row.
Records can be thrown into a container and can and will
loose order in the process. The order should always be defined, like
alphabetical, birthdate or geographical. There is no default order in a
collection of records. [btw: as do "fields"]
This order is only an apparent order, a view. There can be many views.
Rows can be seen as ordered units of a stack,
records as random units of a collection named database table.
Columns can be seen as ordered units of a row,
fields as random units of a collection named record.

I used "LOL" in my initial reply because I really don't care. I understand
what's being talked about regardless of whether "row" or "record", or
"column" or "field" is used. If you want to argue about this, go find Celko

I agree. 58 fields in one table is not a good idea either. It suggests
a lack of normalisation. How many other tables are there in the database?

It is generally recommended that you do not use Jet in a multi-threaded
production enviroment such as a web server. This is particularly important
if you have a lot of records and users.

Greetings,
I'd like to figure out some syntax for retrieving the data from a table
when I don't know all the of field names. What I do know are, the name
of the table, the names of the primary key fields, and the names of the
fields I want to use in the "where" clause of the SELECT statement. All
of the examples I've seen in my books only show how to do this by
hard-coding the names of each of the fields, i.e.,
