I have two columns in a table right now. My query is inserting data into this table from another so that non technical users can view this database value via excel. One column shows the date and the other shows a numeric value. This value grows daily and is used to determine when a reseed of the database is needed. I would like to add a third column to this table that shows the difference in growth. For example if 9/19 had a value of 1000 and 9/20 had a value of 1100, the third column would have a value of 100. My plan is to create a column in excel that calculates the number of days until the reseed is required based on average growth. It would be much easier to get this difference in growth from the database than through an excel formula. Any ideas? Our DBA doesn't know how to do this.
