Hi All, I want to display all duplicate records in the table. My query has to fetch all the records which are duplicate(First Name or Last Name). Also I want the ability to also pull names where there might be a middle initial placed in the end of the first name field, (i.e., "Maria Z. " vs. "Maria") as well. Please guide me to find this. Table: ID FirstName LastName 1 Zach H Hoffman 2 Zach Hoffman 3 Troy Hoffman 4 Shawn Livermore 5 Prem S 6 Jony Hoffman H 7 Zach Modan I need the query to filter......... ID FirstName LastName 1 Zach H Hoffman 2 Zach Hoffman 3 Troy Hoffman 6 Jony Hoffman H 7 Zach Modan I hope this example will give you clear idea..... Thanks in Advance Prem
