| Hi, total sql neophyte here. I have a table (AllTrans) where I need to update one column, AcctID, based on the value in another column, TransID. There are 4500 rows that need updating, and each TransID can have one of 47 AcctIDs. I have an Excel spreadsheet mapping which TransIDs should have which AcctIDs, but I don't have the faintest inkling what the best way to get that info into the sql table is. I figure I could cobble together some type of update-select-case query with 4500 cases, but I'm sure that's not the best way...Any help is greatly appreciated. |

| You're going to need more than just a mapping between TransID and AcctID in this case. You will need a way to identify the appropriate AcctID, and what it should be updated to (so a way to find the "old" ID, and then map it to the "new" ID). |
