RE: fields

Hi Edmund

200 fields is a lot.

If you just have 1 table with 200 fields I would suggest that you break that table down into lots of smaller tables. The purpose of Ms access is to allow you to have lots of tables that hold similar information, these tables are linked together using primary and foreign keys. You can then run reports and queries to extract data.

Hope this helps

Access tip:

Deleting duplicate records from a table

You cannot delete records tables where there duplicate records. A way around this is to create a new table which wont hold the duplicates. and then deleting the old table.

1. Use a make-table query based on this table only. IMPORTANT - Ensure that you include all of the fields from your original table or you may loose data.

2. Open the query's property sheet by using VIEW, QUERY, PROPERTIES, and set the Unique Values property to Yes

3. Because you have selected the Unique Values to Yes when you run the query, Access creates a new table without duplicate records. You can now delete the old table and rename the new one.
