Simple recipe for eliminating duplicates
Problem: A table (MyTable) with a field (name) I need to eliminate records with duplicated name values.
declare @name_unique varchar(50)
declare @tablename table (name_final varchar(50), value text) ---every other field in MyTable
DECLARE cursor_uniquename CURSOR
FOR select distinct name from MyTable
OPEN cursor_uniquename
FETCH NEXT FROM cursor_uniquename
INTO @name_unique
WHILE @@FETCH_STATUS = 0
BEGIN
insert into @tablename select top 1 name,value from MyTable where name=@name_unique
FETCH NEXT FROM cursor_uniquename
INTO @name_unique
END
CLOSE cursor_uniquename
DEALLOCATE cursor_uniquename
truncate MyTable
insert into MyTable select * from @tablename
I wonder if there is a more efficient way, hrmmm...
