Example Dynamic SQL Use Cases

You have an application that takes daily snapshots of the data in one table. You write a stored procedure that takes the table name as a parameter. Using this parameter, you write dynamic queries to analyze the data for one day.

You have a feature tracking database where you track the features that are installed for each customer. You write a stored procedure that takes a customer ID as a parameter. Using dynamic SQL, you create a FEATURE table for the customer (with the customer ID) and populate this table with the default feature set.

You want to write a table analyzer utility that returns the number of rows in a table as well as the number of unique values in each column of the table. Using dynamic SQL, you write a stored procedure that accepts the table name as a parameter and runs the calculations.
