duplicate records. for example, col2 has some values with
2 or more entries. When I execute the below script, I
keep getting errors as indicated below. What is the best
way to delete these 600 duplicates.
script file:
SELECT DISTINCT *
INTO test
FROM livetable
GROUP BY col2
HAVING COUNT(col2) > 1
DELETE livetable
WHERE col2
IN (SELECT col2
FROM test)
INSERT Documents_Convert
SELECT *
FROM test
DROP TABLE test
ERROR MESSAGE:
-- when I run the first part of the script, i get the
bellow error:
--Server: Msg 8120, Level 16, State 1, Line 1
Column 'livetable.col1' is invalid in the select list
because it is not contained in either an aggregate
function or the GROUP BY clause.
--Server: Msg 8120, Level 16, State 1, Line 1
Column 'livetable.col2' is invalid in the select list
because it is not contained in either an aggregate
function or the GROUP BY clause.
--Server: Msg 8120, Level 16, State 1, Line 1
column 'livetable.col3' is invalid in the select list
because it is not contained in either an aggregate
function or the GROUP BY clause.Hi:
I think the error is becasue the misunderstand of select..group by
statement.
If you want to use group by statement, the content you select should in
the group by or have a function tell the machine how to modify the data.

the distinct should give you a unique subset
try omitting the group by clause .

field) in (....)
And After I read the BOL, it seems that we can use in statement in one
field, do you have any suggestion?
