I have the below script that works however I need some help modifying it.
What I now need to do are the following
1. If the day already exists I need to delete all data from that day and insert the new data for the day.
2. if the day does not exist I need to insert the data for the day.
My date format is written as yyyy-mm-dd hh:mm:ss

In it's current form it only inserts data if the current day is greater than the previous day.

Declare @Date As Date
SET @Date = (SELECT Max(CONVERT(char(10),[Date],102)) FROM [dbo].[ESOEmail_Monthly$])
INSERT INTO [dbo].[ESOEmail_Monthly$]
           ,[End Time]
           ,[Team Manager]
           ,[Senior Manager]
                         'Excel 12.0;Database=\\VF_RSOSDCNASUDA\fidopost\National_Command\National Command Centre\SQL\ESO\ESO.xlsm;HDR=YES',
                         'SELECT * FROM [ESOEmail$]')
WHERE (CONVERT(char(10),[Date],102) > CONVERT(DATETIME, @Date, 102))
Any help will be greatly appreciated.
