How to run the same query against many tables
Sometimes you have many similar tables that all need to have the same query run against them. This can be a laborious chore, but with the help of a tool like NimbleText it can be a delight!
First paste your list of tables into the first textbox in NimbleText. Let's say our List of tables looks like this:
dbo.Customers dbo.Customers_Archive dbo.Sales dbo.SalesDetail dbo.Sales_Archive dbo.SalesDetail_Archive
And we want to delete all records more than five years old.
Type a pattern like this into NimbleText:
try it →DELETE FROM $0 WHERE CreatedDate < DateAdd(yyyy, -5, GetDate())
Press 'Calculate' and hey presto:
DELETE FROM dbo.Customers WHERE CreatedDate < DateAdd(yyyy, -5, GetDate()) DELETE FROM dbo.Customers_Archive WHERE CreatedDate < DateAdd(yyyy, -5, GetDate()) DELETE FROM dbo.Sales WHERE CreatedDate < DateAdd(yyyy, -5, GetDate()) DELETE FROM dbo.SalesDetail WHERE CreatedDate < DateAdd(yyyy, -5, GetDate()) DELETE FROM dbo.Sales_Archive WHERE CreatedDate < DateAdd(yyyy, -5, GetDate()) DELETE FROM dbo.SalesDetail_Archive WHERE CreatedDate < DateAdd(yyyy, -5, GetDate())
Copy it from NimbleText over to your favorite query analyzer, and KAPOW! All those old records gone before you can say "Just a minute, I meant 7 years, not 5."
