This type of table is also referred to as a temporary table. These tables are created during the execution of a query and are automatically destroyed once the query has ended. SQL Temp Tables are primarily used to store data that is needed for complex calculations or data processing that requires multiple steps to complete.&#160;<br></p><p>Temp Tables can also be used to store data while waiting for other parts of the query to finish running.<br></p><p><em>&quot;Have you ever wanted to know how to write T-SQL?

Here are some situations where using temporary tables can be beneficial&#58;</p><p><br></p><ol><li>Complex Queries&#58; If you have a complex query that involves multiple subqueries, aggregations, or calculations, using temporary tables can simplify the query structure and make it more manageable. You can break down the query into smaller steps by storing intermediate results in temporary tables and then perform subsequent operations on those tables.</li><li>Performance Optimization&#58; Temporary tables can improve query performance in certain cases. If you have a query that involves multiple joins or expensive computations, you can precalculate and store intermediate results in a temporary table. This can reduce the overall execution time by avoiding redundant computations and optimizing join operations</li><li>Transactional Data&#58; Temporary tables can be helpful when you need to process transactional data within a session. For example, if you are performing a series of operations that involve inserting, updating, or deleting rows, you can store the interim results in a temporary table until you’re ready to commit the changes to the permanent database tables.</li><li>Data Transformation&#58; Temporary tables are commonly used in data transformation tasks. If you need to transform data from one format to another, you can load the raw data into a temporary table, apply the necessary transformations, and then extract the transformed data into the desired format.</li><li>Testing and Debugging&#58; Temporary tables can be handy during testing and debugging processes. You can create temporary tables to simulate specific scenarios or isolate portions of your code for troubleshooting purposes. Temporary tables provide a controlled environment where you can experiment without affecting the actual data.</li></ol><p>It’s important to note that the usage of temporary tables should be considered judiciously, as they have their own overhead in terms of resource consumption and management. Temporary tables are scoped to a session or a transaction and are automatically dropped at the end of the session or transaction, so they are not suitable for storing persistent data.<br></p><h3><b>More links on about Microsoft SQL</b><b></b></h3><p><br></p><ul><li><a data-cke-saved-href="https&#58;//www.sqlservertutorial.net/sql-server-basics/sql-server-temporary-tables/" href="https&#58;//www.sqlservertutorial.net/sql-server-basics/sql-server-temporary-tables/">An Introduction to SQL Server Temporary Tables By ...</a><br>Temporary tables are tables that exist temporarily on the SQL Server.
