We have a large table of customer accounts stored in MS SQL 2008.
I need to add a value to an existing column in this table for a number of accounts. For example, I have a list of account numbers to flag as 'active', and a list to flag as 'inactive'.
I'm reasonably comfortable navigating around SQL Server Management Studio, and I know how to pull a copy of the table into Excel, but I know very little SQL. I'm therefore not sure what the best way to achieve this would be.
What would Spiceheads recommend?
