Hi!
I would like to generate a SQL query to find all duplicate records in my barcode file where each record of the barcode has a date range for valid date.
Say the table is the following...
Barcode, ItemNo, StartDate, EndDate
At any date, there can only be 1 Barcode associated to 1 ItemNo.
How do I write a query to generate all the records that the valid date range overlap?
