Hi, I want to create a DELETE statement which deletes duplicates in a table.
That is, I want to remove all rows - but one - having three columns with the same data (more columns exist and there the data varies). For example: column1 column2 column3 column4 column5 column2 = 'test', column3 = 'hey' and column4 IS NULL for several rows in the table. I want to keep just one of those rows. Is this possible? I can't figure it out, so any help MUCH appreciated! /regards, Håkan Jacobsson - System developer at Relevant Traffic, Sweden ---------------------------(end of broadcast)--------------------------- TIP 6: explain analyze is your friend
