Replacing data

Hi,
In my database, I need to replace a huge amount of data in one field. I wonder if there is a quicker way to replace them all, e.g. using a query?

Thanks. Looking forward to your reply.

Regards,

Xing

RE: replacing data

Hi Xing

Thanks for your question

The quickest method would be to use an update query which can be used to replace specified data within a given recordset.

Can you clarify the following for me so I can be more precise

1. Does the new data exist in some electronic form (database or
spreadsheet)
2. Is the data to be replaced in 1 or multiple tables

Thanks

Stephen

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.
