Totally New To This.
Feb 17, 2008Hi folks,
This is what I want to do,but is it possible.
I think I have got the hang of queries and stuff like that but here is what I want to do.
I am using the 2008 express freebie from microsoft with Sql server 8 freebie.
Here is waht I want to do. Place a load of buttons on a screen each one with a list in it.
so for example box one will specify all the days of the week,the others all the colors of the rainbow and the others all the month in the years.
So the the boxes will feed through to a tiny little sql server database with three tables...days..colours...months.
I want somebody to be able top come along and then click on a particular day of the week...let's say thursday...then click on a colur.lets say pink...then click on a month,lets say september..
Then a table will appear with that info in it..i.e. thursday,yellow september.
I know I could write a little prog in VB or C++ to do this but I am trying to relate it to a database.
I think the bottom line here is that I am trying to get the user to create the query and get the result of that query out onto a page.
As you can see I am just below novice level and I think the question I am really asking is that is it possible that the person using my program is actually making up a query(based on my criteria)and can get a result,rather than me have top store a query(or stored procedure) that just responds to a click on the box.
If this lot makes any sense what so ever,then could someone kind soul point me it the right direction(or any direction) :)
Thanks

Totally Lost -- Please Help
Jul 19, 2004I am looking thru SQL Books, browsing the forum, but still unclear of the best method to perform the following calculation. I am really struggling with this and any helpful hints would be greatly appreciated.
Situation
Table 1 = customer information. Contains customer #, name, address, etc.
Table 2 = default price list. Contains item #, item desc, price
Table 3 = Allowed discounts based on customer types. Hospital gets $1 off, Doctors get 25 cents off, individuals get no discount.
Further discounts are given for multiple purchases. The 1st item is 100%, 2nd item is 75% and 3rd and subsequent items get 50% off purchase that day.
Here is a basic query result set of customer number, price, item ordered, item description and customer type.
Cust Price ItemNo Item Type
1 $5.50 23432 Moisturizer Hospital
2 $5.55 23453 Moisturizer 2 Indvidual
2 $29.00 23243 Lotion Pkg Indvidual
3 $29.00 23243 Lotion Pkg Doctor
3 $21.25 23232 Gloves Doctor
3 $3.00 23235 Drape Doctor
3 $2.00 27821 Lube Doctor
Calculation
Customer 1 ordered 1 item @ 5.50, but because they are a hospital they get a $1.00 discount. They only ordered 1 item so they pay 100% of the discounted price.
(5.50 - 1.00) * 100% = 4.50
Customer 2 ordered 2 items @ 5.55 and 29.00 respectively. They get no discount because they are an individual client, but do qualify for the multiple item discount of 25% for the second item.
29.00 + 5.55 * 75% = $33.16
Customer 3 ordered 4 items @ 29.00, 21.25, 2.00 and 3.00 respectively. They get a 25 cent discount off each item for being a doctor. They also get a multiple item discount of 25% off the second item and and 50% off items 3 and 4.
The math ideally will look like this
(29.00 - .25)*100% + (21.25 - .25)*75% + (3.00-.25)*50% + (2.00 - .25) * 50% = $47
Problem
For customer 2 if someone entered the lower valued item first the math would look like this
5.55 + 29.00 * 75% = $27.30 (loss of revenue)
Possible Solution
The prices need to be sorted in descending order to maximize revenue prior to discounts being taken for a given day.
Should I use a "rank by clause" statement?
Then I need to multiply the first item by 100%, the 2nd by 75% and the remaining items by 50% to get a grand total of money due. Any pointers would be greatly appreciated.
I am not at all sure how to accomplish this.
Stumped. Totally... (but There Must Be A Way!?)
Jul 20, 2005Hi there...I am having a whole bunch of trouble trying to design a certain query. Ihave two tables (see a representation of them here:http://www.plankmeister.org.uk/tables.html ) one called menu_data and onecalled page_data.menu_data contains a list of defined menus (menu_group) which may be sortedaccording to the menu_group_display_order column.page_data contains a list of page definitions. Each page belongs to amenu_group. All the pages in a given group may be sorted according to thepage_display_order column. (for instance, a query to order all pages with amenu_group equal to 1 in ascending order would produce:CatsDogsFishSquirrels)What I am trying to do is to design a query that will tell me thepage_user_name of all the pages that sit at the 'top' of their menu group,but ordered by the menu_group_display_order column.So basically, it will order the data in menu_data by themenu_group_display_order colum, then comparing menu_data.menu_group topage_data.menu_group, will return the 'first' row after being ordered bypage_display_order, so that in the case of the data given, the return wouldbe:HorsesCatsBirdsRabbitsI've tried UNION, GROUP BY, TOP 1, INNER JOIN, OUTER JOIN, SLIGHTLY TO THELEFT JOIN, ONLY IF ITS A WEDNESDAY JOIN... etc etc... But I just can't getit to work! It either returns 40 rows, or one. I've spent a total of about10 hours trying to design this query, and am losing what precious littlehair I have left at an alarming rate.Hope someone can provide some insight!Plankmeister.

Jan 4, 2007I know that the answer to my problem is something that lies right infront my eyes but I got totally stuck. I cant understand why, when I deploy a database application I've made, when the application is run for the second time, the database doesn't have the data I have entered the first time... Is it something I have to tell my application?
It must be something trivial but I just can't put my finger on it.

Hi all of you,
I've got a .dtproj project along with 10 dtsx packages. Up to here everything is fine, every package have its own source files, sql destinations and so on..
Issue comes when I try create a flat file source connection for the eleven one.
I get this message:
The component has detected potential metadata corruption during validation.
Error at Data Flow Task [Flat File Source [1]]: Failed to find any non-special error column in output "Flat File Source Error Output" (3).
It may not be possible to recover to a valid state using a component-specific editor. Do you want to use the Advanced Editor dialog box for editing this component?
Otherwise if I'm gonna to open a new .dtproj project separately no problem at all, I mean, appears the suitable window, "Connection Manager", "Column", "Error output" on the left and so on..
It's very strange. The rest of the packages, the same situation. Fortunately, all of them are stored on the server.
I don't get the point at all. Could you please tell me what the hell is happening?
Thanks in advance and regards,
Totally Confused Connecting Two Tables?
Jan 30, 2008Hello everyone. I need some assistance here. I have a web form to get information about user details. The web form has two parts. the first part is user personal information where there is few textboxes, dropdownlist , radiobuttons , checkbox etc. this is where user inputs his personal information. the second part contains the office information where there is few textboxes, dropdownlist , radiobuttons , checkbox etc too. but the second part is automatically populated by data from the database(lets say table1). this happens as soon as user selects an option from dropdownlist in second part(here an option for dropdownlist is name of the office) . there is also a save and cancel button at the end of the form.now what i want here is, whenever i click a save button in my webform,i want the data of first part of my webform (ie user personal information) to get stored in new table(say table2).but i dont want the data of secont part of my webform(ie office information) to get stored in table2.(coz its already stored in table1.thats from whereit got populated earlier).But i want a reference of second part of my web form(ie office info) in table2.(only the reference id of related data from table1.not the whole data)and finally i want to display data from both the tables in one single details view.(both personal and office information)i hope u people are gettin it?i know i have to use foriegn keys.but i dont know how to use in this case.(sql express)and can u plz explain how to implement this in cs file with example including source code.(c#, vwd2005 express, sql express). thanks. jack.

Apr 26, 2006I downloaded MS SQL Server 2005 Express Edition. The MS site said that it was "easy to install, use and manage." However I'm totally confused. I'm not a total neophyte but I can't even seem to launch the program.
I have an MS SQL database powering my website. I view the database on my home computer using MS Access 2000 with an ODBC connection. MS Access 2000 however, does not let me make changes to the structure of the database. I can't add, delete or modify fields in my current tables. I can't add or delete tables. Is MS SQL Server 2005 Express Edition the proper software to perform these functions? If it is, is there a guide to helping me launch the program, connect to my MS SQL database and perform these functions? If this is not the right software, what is?
I would greatly appreciate any guidance anyone can offer.
Thanks!
Totally Sound Query Not Working In ACCESS
Jan 26, 2006okay so i have query which sure does run fine if i drop it into a SQL server's console. however i try and put this into ACCESS so the accounting department can use it and it returns no values.
not sure if i should drop in the vb forum or what but im about to build a page in c# and have them get it that way.
Any one have any suggestions
Code:
select Doc.Dat, Doc.DocNo, Doc.IdPers, Pos.ItemNo, Pos.[Description], Pos.Quantity, Pos.SinglePrice, Pos.Discount from Pos, Doc where Doc.Dat like '%2005%' AND IdPers = (select IdPers from Pers where match = 'Aec One Stop Group, Inc.') AND Pos.IdDoc in ( select idDoc from Doc where Type = 8 ) ORDER by Dat, DocNo DESC
Implementing Security In Totally Open Environment
Aug 4, 2015I've been parachuted into a place with a few dozen servers, several thousand external users (and scheduled to grow). Right now the whole place - IT and non-IT alike - l logs in with SA.....
(where's the 'Puking' icon??)
They've got Windows logins, but that's about as tight as it gets. Honestly I've never seen anywhere as insecure....and not sure where to start.
Similar Table, But Totally Different Search Performance...
Sep 20, 2007I have two table A and B:
A 2000000 Rows 569288KB 8KB index
B 3000000 Rows 853712KB 8KB index
But when do "SELECT COUNT(*) FROM A/B", table B is significantly slower than A:
A 0 secend
B 8 seconds
Does anyone know why? So I can boost the performance to search table B.
Thanks in advance.
