Determines how ColdFusion processes the first row of the query record set: This tag allows you to specify the MIME type that is returned by the file. You could also specify bitmaps and PNGs as well. If you surround a string field in the text qualifier, the field can contain the delimiter character. This works on ColdFusion 5 and up, and it will show you exactly what comes back when you use this particular tag. The column names for the query, separated by commas, with no spaces.
