Isn't the card type a piece of derived data? You should never have to enter it directly; it's computable from (the first digit(s) of) the card number. - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?

RE: ADO Bulk Inserts
> From: Michael She [mailto:[EMAIL PROTECTED]] > ...So are you saying that the Windows ODBC MySQL driver > doesn't support multiple statements? So far as I know, *no* drivers support multiple statements. However, that's not what you want for "bulk inserts". What you want is multiple value sets in one INSERT statement: INSERT INTO tablename(col1, col2) VALUES (val1a, val2a), (val1b, val2b), (val1c, val2c) That's what you're doing already, right? So I don't understand your issue. - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?

If you want DESC to go along with grade_num, just put DESC with grade_num:
Grade
This seems obvious to me, so I must be missing something. :-)

RE: load data infile syntax
>If the data contains "\", then database will automatically takes "\" >away and shift 1 byte left. >My data will mass up. That is why I still need "\" Does your data actually include backslash characters? If you want to import them as they are, you definitely don't want to ESCAPE BY them. Escaping is used to treat otherwise special characters as nonspecial. For example, quotes and commas have special meaning in some text files, but you can 'escape' the special interpretation by using a scheme like prefixing them with a character that's "more special" than they are. The prefix is usually a backslash, which means that if you really do want a backslash, you need to use two of them (the first one says to treat the next character in a different way than usual). So the moral of the story is this: If you're trying to import backslashes into an SQL table, and your text file doesn't have backslashes doubled, don't choose a backslash as your ESCAPE BY character. - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?

Here's a cute trick for swapping two numbers without using a temporary variable: set a=a-b, b=b+a, a=b-a I don't know how applicable it is to your query, but it might be worth considering. - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?

Instead of including only the hotels having all desired amenities, you might get the results you want by excluding any hotels _lacking_ a desired amenity. - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?
