range - sql between for DAYSOFWEEK -

-

I have generalized search where I am looking at the average values ​​for different days of the week. The problem is that I'm not sure how to ask for a weird limit 1-7 works fine, (Monday-Sunday), but if a user passes on a Tuesday on Sunday ... i.e. 7-2 does not.

1-7 (1,2, 3,4,5,6,7) 7-2 (7,1,2)

etc.

How can I do more than one limit which is more intelligent or something as date (date), bookdata, AVG (price) as availbab item (item_id = 16 And between DAYOFWEEK (Bookdet) and 7) Group by DAIFEE (Bookdate)

Probably what you want is the syntax: 

  SELECT item_id, DAYOFWEEK (bookdate) as the date, bookdate, AVG (price) as the price 'availables' from WHERE (item_id = 16 and DAYOFW EEK (bookdate) IN (7,1,2) Group to Dufofic (bookdet)

-
I have a strange problem that I really do not know. In addition to developing a new ASP.NET site, I have to support the old "classic ASP" site. It is written in VBScript with a batch of JavaScript functions. Many of the JavaScript functions include 'files' Everything is fine on our production system (which security is controlled by another group - this is a military installation) Debugging them once did not work I). However, I have a fix for a vague bug that needs to be fully tested and some functions do not run under the "local" copy of the website that runs on my PC. For the record, I am running IIS 5.1 on XP. The problem is that some Javascript functions are running "OK" on the production server, but when they use it as a server, they are not defined on my PC what is happening that last Programmer, for some reason, has decided to put some functions in a series of files, which according to the observations, imitate the "need_once
