How To Properly Use GO, BEGIN, END

I have writen a small program in a Query window that runs fine if I hilight and run small chuncks. (I have listed the statements with out the clauses so it is more easly viewed here.)

The problem is if I simply execute the Query window I get massive errors that don’t make sence. I am guessing I need some GO and BEGIN/END statements? But I don’t know where I should use them.

I would really appreciate a few pointers so I can just run the Query window.


drop table SourceFile
drop table ReferenceFile

SELECT TOP
INTO SourceFile
FROM

SELECT TOP
INTO ReferenceFile
FROM

-- test data
INSERT ReferenceFile
(AddressCleanedPK, New_First_Name, New_Last_Name, New_Address, Phone, Zip)
values ()
INSERT SourceFile
(AddressCleanedPK, New_First_Name, New_Last_Name, New_Address, Phone, Zip)
values (22)
-- test data


drop table MATCHTEST
SELECT TOP 1 AddressCleanedPK, New_First_Name, New_Last_Name, New_Address, Phone, Zip
INTO MATCHTEST
FROM AddressCleaned_npidata_20050523_20071112

DELETE MATCHTEST

ALTER TABLE MATCHTEST
ADD REF_ML VARCHAR(2)

INSERT MATCHTEST ()
SELECT
FROM ReferenceFile r
inner join SourceFile s
on s.New_Last_Name = r.New_Last_Name

select * from MATCHTEST
