Selecting data from two different servers in SQL Server
How can I join two tables, which are located two different SQL Server instances, in one query?

Solution. Select column values in a specific order within rows to make rows with duplicate sets of values identical. Then you can use SELECT DISTINCT to remove duplicates. Alternatively, retrieve rows in such a way that near-duplicates are not even selected.
The SQL UNION ALL operator is used to combine the result sets of 2 or more SELECT statements. It does not remove duplicate rows between the various SELECT statements (all rows are returned). Each SELECT statement within the UNION ALL must have the same number of fields in the result sets with similar data types.
Check for Duplicates in Multiple Tables With INNER JOINUse the INNER JOIN function to find duplicates that exist in multiple tables. Sample syntax for an INNER JOIN function looks like this: SELECT column_name FROM table1 INNER JOIN table2 ON table1. column_name = table2.
The best way I can think of to accomplish this is via sp_addlinkedserver. You need to make sure that whatever account you use to add the link (via sp_addlinkedsrvlogin) has permissions to the table you're joining, but then once the link is established, you can call the server by name, i.e.:
SELECT * FROM server1table INNER JOIN server2.database.dbo.server2table ON ..... If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
