Solution
In the context of stored procedures, the distinction between an IN parameter and an OUT parameter lies in their purpose and usage.
An IN parameter is used for passing values into the stored procedure. It allows the procedure to receive input values that can be used for various operations within the procedure. These values are typically provided by the caller of the procedure.
On the other hand, an OUT parameter is used for retrieving values from the stored procedure. It allows the procedure to return specific values or results back to the caller. These values are typically generated or modified within the procedure and are intended to be used by the caller after the procedure has been executed.
To summarize, IN parameters are used for passing values into the stored procedure, while OUT parameters are used for retrieving values from the stored procedure.
