The process of [SQL Server](https://www.mindstick.com/articles/12999/what-is-table-valued-function-in-sql-server) [database](https://www.mindstick.com/articles/12226/use-of-database-in-sencha-extjs-and-insert-record-from-user-form-using-ajax) comparison includes both dataset analysis for identifying missing records as well as the detection of changes within column values. Your requirements determine which approach you should use to achieve row and column comparison in an SQL Server database.

You can perform table row comparison with `JOINs` or through the use of `EXCEPT` and `INTERSECT` or with `FULL OUTER JOIN`. An `INNER JOIN` locates pairs while `LEFT JOIN` and `RIGHT JOIN` show which records do not match. This operation allows viewing data rows that exist within one database but not in the other. articles that exist between both tables appear during an `INTERSECT` operation. A `FULL OUTER JOIN` provides valuable results about unmatching records along with any absent data across both tables in the analysis.

The `CASE` statement enables row-wise value comparison inside `SELECT` statements when checking for different values between columns from the same table. Entire row comparisons become efficient when you use `CHECKSUM()`or `HASHBYTES()` function which generates hash values for both tables.

A `FULL OUTER JOIN` connection with the use of `ISNULL()` or `COALESCE()` helps identify differences in particular table column values between two databases. The `PIVOT` operator functions as a tool to evaluate multiple columns as they span across diverse rows.

To work with large datasets the process becomes more efficient by indexing important table columns alongside using automated comparison tools through SQL Server Data Compare.
