Microsoft access combine tables. I have no much access experience.?

The two tables are the same kind data but with some duplicates. I am thinking to combine it first, then delete the duplicates from the combine list. I have no prior experience using Microsoft access.

If you want to AUTOMATE then here's what you can do. Create three queries:



Query1:



SELECT IDNO, First(Table1.NAME) as NAME



FROM Table1



WHERE IDNO In (SELECT [IDNO] FROM [table1] As Tmp GROUP BY [IDNO] HAVING Count(*)%26gt;1 )



GROUP BY IDNO;



Query2:



SELECT Table1.IDNO, Table1.NAME



FROM table1 LEFT JOIN Query1 ON (table1.NAME = Query1.NAME) AND (table1.IDNO = Query1.IDNO)



WHERE



ISNULL(Query1.IDNO);



Query3:



SELECT IDNO, NAME



INTO Table3



FROM Query2;

Lets say you have two tables Tab1, Tab2. You want to merge them.



1. Select Tab1. Right Click and select Copy.



2. Right Click on empty space in Table view, select Paste.



3. From options dialog, enter Tab2 as table and select last option ''Append Data to Existing Table''



You are done. Its as easy as this.



Then sort the table Tab2 on required columns to find duplicate records, then delete them.
