Dynamic Table Variable Usage
The dynamic table variable can be used to get input from the user from the front-end at runtime or may be due to some choice from user action. By this method, the user can get data from different tables to display data in the front end based on some criteria. So the front end can send the table name dynamically from a text-box input to back-end to fetch data from different tables based on user input. There can also be other use cases for using a dynamic table name at run time.
We can create stored procedures that accept the table name as a parameter to accept different table names at run time to make the same procedure re-usable for different tables.
There can also be some situations where tables are created dynamically and data inserted at run time. Here also we can use the dynamic table name variable to handle these situations.
Dynamic Table Name Variable in SQL Server
In SQL Server, the dynamic table name variable is used when the name of the table is not explicitly stated in a query but is set in a variable and used instead. This can be in situations where the user does not know or the executing code does not know the table name beforehand and is only determined at run time.
