Need Help Writing a Query.

OK, i have been trying to write a query now and have gone in several different directions and find myself stuck back at square one and was hoping someone could help me out.
Here is my issue and i'll try to explain as best as i can.
Example: i have the following data.
Desc 1 --- Instruct 1 --- 2/2/2009
Desc 1 --- Instruct 1 --- 2/7/2009
Desc 1 --- Instruct 1 --- 2/3/2009
Desc 1 --- Instruct 2 --- 2/5/2009
Desc 2 --- Instruct 1 --- 2/3/2009
Desc 2 --- Instruct 1 --- 2/1/2009
What i need to do is write a query that will show distinct Descriptions as well as distinct instructions. (Example, Desc 1 could have 7 different instructions, so i would need 7 different lines for Desc 1, with the most recent date and a count for how many occurances of each specific instruction, for each specific Description for each of the 7 lines for Desc 1.
Example of results would be like this
Desc 1 --- Instruct 1 --- 2/7/2009 --- 3
Desc 1 --- Instruct 2 --- 2/5/2009 --- 1
Desc 2 --- Instruct 1 --- 2/3/2009 --- 2
Hopefully that is enough information, but if anything else is needed for me to provide in order to get some help, just let me know and i will do my best to get that information.
thanks in advance

FROM      table_x
GROUP BY descrrption
,         instruction;"GROUP BY x, y" means the output will contain one row for every distinct combination iof x and y that occurs in the results.
All the columns in the SELECT BY clause must be
(a) in the GROUP BY clause,
(b) aggregate functions (like MAX or COUNT), or
(c) trivially dependant on (a) or (b) (for example: UPPER (description))Thank you;
I think i was trying to over complicate things.
So simple, yet so very effective
thanks again

Need help writing a query for following scenario

Hi all, I need some help writing a query for the following case:
One Table : My_Table
Row Count: App 5000
Columns of Interest: AA and BB
Scenario: AA contains some names of which BB contains the corresponding ID. Some
names are appearing more than once with different IDs. For example,
AA BB
Dummy 10
Me 20
Me 30
Me 40
You 70
Me 50
Output needed: I need to write a query that will display only all the repeating names with their corresponding IDs excluding all other records.
I would appreciate any input. Thanks

Is it possible to have a records with the same values for AA and BB? Are you interested in these rows or do you only care about rows with the same value of AA and different BB?
With a slight modification of a previous posting you can only select those rows that have distinct values of BB for the same value of AA
WITH t AS (
SELECT 'me' aa, 10 bb FROM dual
UNION ALL
SELECT 'me' aa, 20 bb FROM dual
UNION ALL
SELECT 'you' aa, 30 bb FROM dual
UNION ALL
SELECT 'you' aa, 30 bb FROM dual
SELECT DISTINCT aa, bb
FROM (SELECT aa, bb, COUNT(DISTINCT bb) OVER(PARTITION BY aa) cnt FROM t)
WHERE cnt > 1;

Need help writing a query that generates sequential tokens

Updated example to accomodate duplicates in cacard and to change the #temp_tokentable.cccard to varchar(20).
I am just having a block. I have a should be easy task, and have looked at it several ways, but cannot come up with some tsql that I would not be embarressed to show coworkers.
This is a the simplistic example of what needs to get done -
cacard table has credit cards. need to replace all credit cards with a generated token. the token is generated by just adding 1 to the lasttokenused and then + the right(creditcard, 4). Then the token and clear credit card values are inserted into
tokentable.
cacard can be a rather large table (# of rows and wide) in production so need to be as efficient as possible. But it is a onetime conversion program.
Thanks for any help

Thought that I would post the code that reads a credit card number file and replaces card numbers
with token values. The tokens keep the last 4 of the original credit card number. I have two example card number tables. One table -cacardn - has a numeric(19,0) card number and the other - cacardv - has a varchar(20) card
number. My shop has credit card numbers defined as both. Obviously, another step after this runs is to encrypt the #token.data column.

Need help writing sql query

i am trying to write sql query for a single recordset.
I have an items table with all the standard item info and an item_colorID.
i have a color_lookup table with 2 columns, item_colorID and color_ID
i have a colors table with 2 columns, color_ID and color
i want to join the tables and filter it so that a repeat region shows dynamic data of item name, description, thumb, price
and also a list/menu dynamically populated by color
filtered so that each item shows in the list/menu only the colors that the item has available.
i have tried different variations of this sql
SELECT * FROM items INNER JOIN color_lookup ON color_lookup.item_colorID = items.item_colorID INNER JOIN colors ON colors.color_ID = color_lookup.color_ID WHERE items.itemCatID = 3 ORDER BY items.itemName
but the list/menu shows every color choice multiplied by the number of items in that color
ie White will show 80+ times.
thanks for your help,
jim balthrop

bregent,
thanks for your help.
I am building a shopping cart and i have a recordset to list the items and a repeat region for that recordset
i have a second recordset for the colors joined to the item_colorID nested inside the repeat region.
the shopping cart software has a 'lookup from recordset' choice for the add to cart servior behavior
and then i bind to the columns on the cart page.
it produces this code
if (isset($totalRows_rs_itemscat3) && $totalRows_rs_itemscat3 > 0)    {
    $row_rs_itemscat3 = WAEC_findRecordMySQL($rs_itemscat3, "item_ID", $ATC_itemID);
    if ($row_rs_itemscat3)    {
      $ATC_itemName = "".$row_rs_itemscat3['itemName'] ."";// column binding
      $ATC_itemDescription = "".$row_rs_itemscat3['itemShortDesc'] ."";// column binding
      $ATC_itemWeight = floatval("".$row_rs_itemscat3['itemWeight'] ."");// column binding
      $ATC_itemQuantity = "".$_POST["Farrington_1_Quantity_Add"] ."";// column binding
      $ATC_itemPrice = floatval("".$row_rs_itemscat3['itemPrice'] ."");// column binding
      $ATC_itemThumbnail = "".$row_rs_itemscat3['itemThumb'] ."";// column binding
      $ATC_itemcolorchoice = "".$row_rs_colors['color'] ."";// column binding
      mysql_data_seek($rs_itemscat3, 0);
      $row_rs_itemscat3 = mysql_fetch_assoc($rs_itemscat3);
the column binding for the colors is from a different recordset and when redirecting to the cart page the color info will not show.
So my thinking is if i could get the color list/menu to populate from the same recordset as the item listing, it would solve my add to cart server behavior.
Is it possible to do this with only one recordset?
the products page and the cart page can be seen
http://www.farrington-enterprises.com/rain-gutters.php
add an item to the cart with any color choice and the color info does not carry to the cart.

Need Help writing cfloop query

I have a form with variables in it that is a duplicate. For
example I have id1, id2, id3. I have a loop and query set up like
this:
<cfloop index="i" from="1" to="3">
<cfquery name="insert_info" datasource="#dsn_slave#">
INSERT INTO new_samples (email, id, od, id_min, id_max,
cs_min, cs_max, material, durometer, quantity, units_of_measure,
timestamp) VALUES (#email#, #id#, #od#, #id_min#, #id_max#,
#cs_min#, #cs_max#, #material#, #durometer#, #quantity#, #measure#,
#CreateODBCDateTime(Now())#)
</cfquery>
</cfloop>
How do I set up id1 in the loop meaning how do I write it to
use my index=i so that it will add the 3 sets of values?

Assuming that you're form fields are required, validated,
checked for their existence, etc., you could take the following
approach:
<cfloop from="1" to="3" index="i">
<cfquery name="instForm" datasource="dsn">
INSERT INTO new_samples (email)
VALUES ('#FORM["email"&i]#')
</cfquery>
</cfloop>
Naturally, add in the other fields...I'm too lazy to write
the whole query :)!
Hope this helps!

'b'
'c'
'd'
'e'
I am writing a query as :
SELECT * FROM test9 WHERE Name IN ('a','b','c','d','e','f','g')
I want result set as , It should show data as -

i.e. data which does not exists in the table and which is give in in clause
Is it possible in a single query.

You can put the data that is to be checked for into a table instead or an inline view, for example:
with t as
(select 'a' as c1 from dual
union all
select 'b' from dual
union all
select 'c' from dual

Need help writing host program using LabView.

Need help writing host program using LabView.
Hello,
I'm designing a HID device, and I want to write a host program using National Instrument's LabView. NI doesn't have any software support for USB, so I'm trying to write a few C dll files and link them to Call Library Functions. NI has some documentation on how to do this, but it's not exactly easy reading.
I've written a few C console programs (running Win 2K) using the PC host software example for a HID device from John Hyde's book "USB by design", and they run ok. From Hyde's example program, I've written a few functions that use a few API functions each. This makes the main program more streamlined. The functions are; GetHIDPath, OpenHID, GetHIDInfo, Writ
eHID, ReadHIC, and CloseHID. As I mentioned, my main program runs well with these functions.
My strategy is to make dll files from these functions and load them into LabView Call Library Functions. However, I'm having a number of subtle problems in trying to do this. The big problem I'm having now are build errors when I try to build to a dll.
I'm writing this post for a few reasons. First, I'm wondering if there are any LabView programmers who have already written USB HID host programs, and if they could give me some advice. Or, I would be grateful if a LabView or Visual C programmer could help me work out the programming problems that I'm having with my current program. If I get this LabView program working I would be happy to share it. I'm also wondering if there might already be any USB IHD LabView that I could download.
Any help would be appreciated.

I am trying to write a query to aggregate paid_amount based on Reference_No, Check_Number, Payment_Date, Invoice_Number, Invoice_Type, Vendor_Number and display description with Invoice_type 'I' when there are multiple records with the same Reference_No, Check_Number, Payment_Date, Invoice_Number, Invoice_Type, Vendor_Number. When there are no multiple records I want to display the respective Description.
The query should return the following data set

I need help writing a script that finds the first instance of a paragraph style and then changes it

I need help writing a script that finds the first instance of a paragraph style and then changes it to another paragraph style. I don't necessarily need someone to write the whole thing, by biggest problem is figuring how to find just the first instance of the paragraph style. Any help would be greatly appreciated, thanks!

Hi,
Do you mean first instance of the paragraph style
- in a chosen story;
- on some chosen page in every text frames, looking from its top to the bottom;
- in a entire document, looking from its beginning to the end, including hidden layers, master pages, footnotes etc...?
If story...
You could set app.findTextPreferences.appliedParagraphStyle to your "Style".
Story.findText() gives an array of matches. 1st array's element is a 1st occurence.
so:
Story.findText()[0].appliedParagraphStyle = Style_1;
//==> this will change a paraStyle of 1st occurence of story to "Style_1".
If other cases...
You would need to be more accurate.

Hi. I'm learning Java programming, and I need help writing a small program. Please someone help me.
Directions:
Create a program called CerealCompare using an if-then-else structure that obtains the price and number of ounces in a box for two boxes of cereal. The program should then output which box costs less per ounce.

campaigns. We want to add to her website a form taht submits the
information needed to subscribe to her email list, to constant
contact via API.
FORM.asp :: (i got this one under control)
name
email
and submits to serverside.asp
SERVERSIDE.ASP
In serverside.asp i need to have
the API URL
(https://api.constantcontact.com/0.1/API_AddSiteVisitor.jsp)
username (of the constant contact account)
password (of the constant contact account)
name (submited from form.asp)
email (submitted from form.asp)
redirect URL (confirm.asp)
Can anyone help get me going in the right direction?
i have tried several things i found on the net and just cant
get anyone to work correctly.
One main issue i keep having is that if i get it to submit to
the API url correctly - i get a success code, it doesnt redirect to
the page i am trying to redirect to.
ASP or ASP.NET code would be find.
THANKS

If you are submitting a form to a script on a remote server,
and letting
that script load content to the browser, YOU have no control
over what it
loads UNLESS there is some command you can send it that it
will understand.
No amount of ASP on your server is going to change what the
remote script
does.
http://www.constantcontact.com/services/api/index.jsp
they only allow their customers to see the instructions for
the API so i
can't search to see IF there is a redirect you can send with
the form info.
But posts on their support board say that there is.

Need help defining a query

Hi everyone...
I need help with this query. The table 'cobros' has a primary key defined by id_cliente + id_cobro. I pretend to classify rows by COUNT(id_cobro) which are between a date range.
A client could have 1 or 2 or 3 rows per day, no more for a specific date. I would like to get first, all clients with COUNT(id_cobro) = 1, all clients with COUNT(id_cobro) = 2, and finally all clients with COUNT(id_cobro) = 3.
Something similar to:
1 SELECT id_cliente, COUNT(id_cobro) FROM cobros
2 WHERE fecha_proximo_cobro >= '2011-05-30 00:00'
3 AND fecha_proximo_cobro <= '2011-05-30 23:59'
4 AND COUNT(id_cobro) = 1
5 GROUP BY id_cliente
The fourth line is the problem. It doesn't work.
Thanks in advance!!!
Mario

Maybe you are looking for something like this?
SELECT id_cliente
     , COUNT(*)   AS cnt
FROM   cobros
WHERE fecha_promixo_cobro BETWEEN TO_DATE('2011-05-30 00:00','YYYY-MM-DD HH24:MI') AND TO_DATE('2011-05-30 23:59','YYYY-MM-DD HH24:MI')
GROUP BY id_cliente
ORDER BY 2
       , 1Also, NEVER rely on implicit data type conversion as you have (you provide a STRING not a DATE).
