I thank you for the suggestions. I currently have tried all of them. The best one that I found, which worked for this purpose, was from both Dore and Ken. The question that I have is there a way to keep everything in the same table without having to copy to a new table? Basically, the process everything is going through is via a REINDEXing program.
Weekly, the records of this table (386,548 records)are being reindexed, but many of them are duplicate invoice no. (i.e. J123451 has 6 of the same records). I want to keep the first records and delete all proceeding records of the same invoice number. While I wish we could have a candidate key to prevent this, it's not the company's interest.
Just for my knowing, would this be the most optimized process of clearing out deleted records?
Thanks again for the help!!
