DON'T SHOUT. Using all capitals is considered shouting on the internet, and rude (using all lower case is considered childish). Use proper capitalisation if you want to be taken seriously.

Seems kind of pointless but if you want to do this then just add 1 to the previously saved value. Then the next day, start over from 1.

Example stored procedure:

SQL

CREATE PROCEDURE GetClientIDForDay()
AS
BEGIN
    DECLARE @aDay DATE
    DECLARE @CId INT

    SET @aDay = GETDATE()
    SELECT @CId = MAX(COALESCE([customer_of_today],0))
    FROM YourTable
    WHERE [SalesDate] = @aDay


    RETURN @CId
END

Probably you need to make query conditional on customer number.

Hi,
Before you save entries into database, get the count of the entries for that day, check on google for "SQL COUNT". when you get the count of entries in the db for that selected day, use (count + 1) as your serial number on the new entry.

SQL

SELECT COUNT(Datecolumn) FROM Customers WHERE DateColumn='2013-03-05'

Hope this helps.

Regards
Jegan

OP wants to get customer number of the day, but not to count no. of transactions.

The number of customers entered into customer table per day is the count of number of transactions per day for that table.
