Generating a 5-digit sequence number in SQL Server

In SQL Server, you can generate a 5-digit sequence number using various methods. One common approach is to use an IDENTITY column combined with the FORMAT function. Here’s an example to illustrate the process: 


        -- Create a table with an IDENTITY column
        CREATE TABLE SequenceExample
        (
            Id INT IDENTITY(10000, 1) NOT NULL,
            SomeData VARCHAR(100) NOT NULL
        )
        
        -- Insert some dummy data into the table
        INSERT INTO SequenceExample (SomeData)
        VALUES ('Example 1'), ('Example 2'), ('Example 3')
        
        -- Retrieve the generated 5-digit sequence number
        SELECT FORMAT(Id, 'D5') AS SequenceNumber, SomeData
        FROM SequenceExample

In this example, we first create a table called “SequenceExample” with an IDENTITY column named “Id” and a VARCHAR column named “SomeData”. The IDENTITY column starts with a value of 10000 and increments by 1 for each new row.

Next, we insert some dummy data into the table. The IDENTITY column will automatically generate a unique sequence number for each inserted row.

Finally, we retrieve the generated 5-digit sequence number using the FORMAT function in the SELECT statement. The ‘D5’ format specifier ensures that the number is displayed as a 5-digit string, even if leading zeros are required.
