Hi,
I need to Update Column Value based on another table.
Existing_Table
Id Date
N 9/10/2008
N 9/11/2008
N 9/17/2008
N 9/18/2008
New Table
Id Current Date
N 9/10/2008
N 9/11/2008
N 9/17/2008
N 9/18/2008
Based on New table Current Date Change the column value in Existing table. If current date is less than 3 days of Date column in existing table Update the id column is 'U'. How can i write the query?
