I have two tables: Table 1, Symbols, contains a colum for the stock symbol. Table 2, Weights, also contains a column for the stock symbol. Somehow, when I was entering values into an excel spreadsheet that I later imported into MSFT SQL server, I accidentally typed in duplicate symbols into the Weights table. Is there a sql query that I can use that will return symbols in the Symbols table that are missing from Weights table? I tried this but the sql interpreter doesn't like it: Code: select Symbols.symbol from Symbols inner join Weights on Weights.symbol = Symbols.symbol where Symbols.symbol is not in Weights.symbol Thanks. nitro

How about using "left outer join" select symbols.symbol, weights.weight from symbols left outer join weights on weights.symbol = symbols.symbol where weights.weight is null

I think that did it!!! Code: select symbols.symbol, weights.symbol from symbols left outer join weights on weights.symbol = symbols.symbol where weights.symbol is null Thanks
