    Can'f figure out this conversion issue. Please Help!

    Here is the query:
    select CONVERT(money, Amount) as amount from
    I need to convert column "Amount" which is varchar(50) datatype to a column of datatype money. I am getting the following errror:
    Server: Msg 235, Level 16, State 1, Line 1
    Cannot convert a char value to money. The char value has incorrect syntax."

    Any ideas?

    I would guess that you have a value in the Amount field in Temp_Table that has some kind of character in it that is not numeric. You could try something like this to find the offending row:

    SELECT *
    FROM Temp_Table
    WHERE ISNUMERIC(Amount) = 0

    This should find all rows that will not convert to money so you can fix them. I did some testing and noticed that ISNUMERIC will evaluate to true even if there is a '$' in the data.
