In this article, we will explore in detail the factors that cause SQL Server stored procedures to be recompiled. Introduction SQL Server Stored procedures are the make-ready T-SQL codes that can be executed again and again by the database users to perform data manipulation commands and data definition commands.

The simplest definition of a log record: it describes a single change to a database. An example of this is updating a fixed-width column in a single row—it will do the following: Perform the update, which generates one log record. It can be fascinating to spelunk around in the log to see what SQL Server is doing for some operations.
