In addition to the other replies you've gotten on this, I think it can depend on the data, too. Is your VALUE1 field is a character field, but contain mostly numbers? If so, I have the same situation in one of my databases here. I often search using a number, and it often works. On certain fields, however, I tend to run into a type conversion error. I suspect it must be converting the field values to numerics to compare them with what you've passed. If all the rows actually have values that can be converted to numeric, fine. If not, however, I get an error. So two databases with the exact same structure and settings, but different data, can work differently. (My database is Oracle, but I'm speculating that others may behave similarly.) In any case, bottom line is, just don't rely on implicit type casting. - John -- This message may contain information which is private, privileged or confidential and is intended solely for the use of the individual or entity named in the message.
