[Document] NVARCHAR NOT NULL
)

2. You have a database that contains the tables as shown below:

You have a stored procedure named Procedure1. Procedure1 retrieves all order ids after a specific date. The rows for Procedure1 are not sorted. Procedure1 has a single parameter named Parameter1. Parameter1 uses the varchar type and is configured to pass the specific date to Procedure1.

You need to update the SELECT statement to meet the following requirements:
The code must NOT use aliases.
