Copy Data To SQL Server By Checking (available)

Hello,

I connect from SQL Server on Windows 2000 to Progress
Database on UNIX.
The database name of SQL Server is cstarsql and the
name is cstarint on UNIX.

I would like to schedule to copy data from
cstarint(Progress) to cstarsql(SQLServer). I did for
one time, but I want to control if the data has
already copied or not. If not, it will copy.

In DTS Query Builder to copy from Progress to SQL
Server,
SELECT * from calls WHERE call_date = TODAY
The name of table of calls is the same for both
database.The above calls is cstarint(Progress
Database)
This command is enough for one time. But I need to
control if the record has already copied.


In SQL Server, I control if the record is available or
not with @@FETCH_STATUS .
Now I would like to mix two queries, but I couldn't.
Can anybody do this?

DECLARE calls_cursor SCROLL CURSOR
FOR SELECT * FROM calls
WHERE call_date = TODAY

OPEN calls_cursor

-- Perform the first fetch.
FETCH NEXT FROM calls_cursor

-- Check @@FETCH_STATUS to see if there are any more
rows to fetch.
WHILE @@FETCH_STATUS = 0
BEGIN
-- This is executed as long as the previous fetch
succeeds.
FETCH NEXT FROM calls_cursor
END

CLOSE calls_cursor
DEALLOCATE calls_cursor
