What you would learn in Building and executing stored procedure in SQL course?
Storage procedures are written SQL scripts that could save so that they can be reused times and repeatedly.
If you have an SQL query that you have to write repeatedly, Save your query in a store process and then run it to run it.
It is also possible to pass parameter values to a stored procedure so that the stored process can be executed based on the parameter value(s) sent.
A stored procedure is utilized to access and edit the data or delete it within a database table. It's unnecessary to write a complete SQL command every time you need to add, update or delete data from your SQL database.
Benefits of using a store procedure
It is easily modified. It is possible to modify the code within the stored process without restarting or deploying the application. For instance, if the SQL queries are written within the application, and we want to alter the logic, we have to alter the code inside the application, then deploy it again. SQL Server Stored Procedures can solve these issues by storing the code within the database. So, if we need to modify the logic of the procedure, we can perform it using an altered procedure statement.
In reducing network traffic, we employ stored procedure instead of writing queries at the level of application, just the name of the procedure is transmitted across the network instead of the entire T-SQL query code.
Reusable: Stored procedures can be executed in multiple ways by different users or client applications without writing the code again.
Security: Stored procedures decrease the risk because they block direct access to tables. We can also secure the stored procedures when creating them so that the source code contained in the stored procedure isn't accessible.
