Thanks in advance..   Mon, 13 May 2019 19:09:00 GMT https://community.blueprism.com/t5/Product-Forum/SQL-Query-EXCEL-OLEDB/m-p/47224#M3014 NagaYaparla 2019-05-13T19:09:00Z https://community.blueprism.com/t5/Product-Forum/SQL-Query-EXCEL-OLEDB/m-p/47225#M3015 An inner join will return only the data matching the criteria. Think of a Venn diagram with 2 intersecting circles - the inner join is represented by the intersecting area. However there are other types of join, eg 'left outer join' that may be worth some research to see if they will provide what you want.

Try changing the WHERE clause to: WHERE [Sheet1$].[name] = [Sheet2$].[name] AND [Shee1$].[Email][Sheet2$].[Email] That should give you your desired output.  But John is right, definitely explore different types of join.  You can work wonders with just INNER JOINS and LEFT OUTER JOINS.
