SQL how to compare two tables from different servers? - sql

I have a table job_order with column order_no in my store_db. Is there a way or query that I can compare if data from the order_no column matched with the same column but on a different database server?
Note that server1 and server2 has the same database. I would appreciate the help. Thank you!

Different approaches can be used to achieve the table comparison:
Create a Linked Server connection, then create a Stored Procedure that performs a comparison on the Target Server.
A wide option exists to achieve an effective table data comparison.

If you are trying to connect databases in two different servers,You can add of them as linked server.
Then you can access the data from that server, for example if you are adding server1,then you can access the table using the following query.

If you wanted to access from a different Database of the same server.Then use the following code for accaeeing the table data.
SELECT *
FROM YourDatabaseName.YourSchemaName.YourTableName

Compare two tables with different schema in SQL Server

I have two tables in different databases with different schema, how can I compare them both?
Let's say I have the DB1 with the table history.Table1 and another DB2 with the same table but in a different schema, backup.Table1.
Now I need to compare what's different besides the schema name obviously.
Try SQL Compare from Redgate. They allow you to compare pretty much everything from the actual data to the schema.
I dont believe there is any native functionality in sqlserver.

Alter table schema based on another table

In sql if i had 2 databases where each had similar columns but not exactly the same schema , is there a built in way to alter the schema of a table in database2 make it similar to the schema in of a table database1?
considering that the column type and column name and default value are the factors to decide if 2 columns match.
No, there is no built in functionality for doing this, you will either have to do it manually or use a comparison tool such as RedGate SQL Compare or Visual Studio.
