This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind.
"not repeat data in my database" could mean anything - are we talking about reading data out, or putting data in? How are you doing whatever it is at the moment, because there are a huge range of ways it could be done!

    UPDATE.......
ELSE
    INSERT INTO Table1 VALUES (...)
