How to write a SQL Server statement to insert records into 1 table from another using SQL Server 2005?
I am working with SQL Server 2005.
I have 2 SQL Server tables named tblNew and tblCum.
These tables have identical data structures and field names.
The first field in the tables is named MailID and is unique.
How would you write a SQL Server statement to insert records into table tblCum from table
tblNew where MailID in tblNew is not in table tblCum?
