Re: [MSAccessProfessionals] Union Query vs. Append query

Let me ask a related question.

Everyday I add about a 1000 records to my database. I currently import these into a new table and then through a union query combine them with my currrent records. At the end of the month I take all the daily tables and combine them into a monthly table and modify the union query to reflect that. So currently I have a union query that is combining 6 tables of monthly data and approximately 10 days of daily data to create a master data set. Would it be better if I just appended the new data everyday to a single table?

I'm confused, as the two types of queries do different things.  You'd need to use the type that accomplished your goal.

Do you get 295k new records a day, or is that the total number of records in the table?  If the total, that's not really a large number, so you may not need to delete records.

Hello all,

I download every day records from hyperion and bring them into the database after exporting them to excel and then importing them into the database. because the record count is 295K i delete the records in the database from a certain date and then append the newly downloaded records thus keeping my record count low. 
But I was thinking today. what would be faster to do a union query or an append query?

Thanks for the thoughts
