Help With A Complex UPDATE Query

Nov 18, 2006

Well, I think it's complex anyway -- you might not :)

TableDef:
CREATE TABLE CustTransactions (
TransactionKey int IDENTITY(1,1) NOT NULL,
CustomerID int,
AmountSpent float,
CustSelected bit default 0);

TransactionKey is the primary key, CustomerID and AmountSpent are both
indexed (non unique).

What I would like to do is, for all of the records in descending order
of "AmountSpent" where "CustSelected = TRUE", set CustSelected to FALSE
such that the sum of all the AmountSpent records with CustSelected =
TRUE is no greater than a specified amount (say $50,000).

What I'm doing at the moment is a "SELECT * FROM CustTransactions WHERE
CustSelected = TRUE ORDER BY AmountSpent;", programatically looping
through all the records until AmountSpent 50000, then continuine to
loop through the remainder of the records setting CustSelected = FALSE.
This does exactly what I want but is slow and inefficient. I am sure it
could be done in a single SQL statement with subqueries, but I lack the
knowledge and experience to figure out how.

The closest I can get is:-

UPDATE CustTransactions SET CustSelected = FALSE
WHERE (CustSelected = TRUE)
AND TransactionKey NOT IN
(SELECT TOP 50000 TransactionKey FROM CustTransactions WHERE
(((CustTransactions.CustSelected)=TRUE))
ORDER BY AmountSpect DESC, TransactionKey ASC);

However, this mereley ensures only the top 50,000 customers by amount
spent remain "selected", not the top "X" customers whose total spend
is $50,000. I really need to replace the "SELECT TOP 50000" with some
form of "SELECT TOP (X rows until sum(AmountSpent) =50000)".

Is it even possible to achieve what I'm trying to do?

Thanks in advance for any assistance offered!

Very Complex Query

Mar 19, 2007

I'm sure there is a way of cracking this, but I can't think of a good solution. Right now I am not happy with the solutions I come up with, one of which takes 4 minutes to run on SQL Server
The scenario: User is presented with search page where one or more search terms can be entered/selected. There are no required parameters. It can be any or all of the possibilities presented. Below is a model of the search parameters presented.
The user will either select to show more options under Profile ABC, or go down to Profile STU or Profile XYZ to show more options, or even select all Profiles and then select from Type 1 and either a. or. b. or. c. or ALL of the above.
I cannot predict what a user will make part of the search query so I have to have a stored procedure ready which can handle any or all of the parameters  a user may select.
Am I biting off more than I can chew (it seems so)? Or is there an elegant way of handling the unknown combination of search parameters that a user might throw into my sql query?
I'm running this under ASP 1.0 and SQL Server 2000.
 
[check to show the options below] Profile ABC
[check to shore more options] Type 1




A. Contains fields for entering another data string and selecting from drop-down boxes
B. ditto
C. ditto
D. ditto
[check to show more options] Type 2

Complex Query?

Feb 8, 2005

I have 2 tables, say table1, and table2. There is a DocID (primary key) in table1. In table2, DocID is the foriegn key. There can be more than 1 DocID.

this is the table structure (sample)

Table 1:
DocID DocName OtherID etc
1 test 2
2 test2 3

Table2:
TblID DocID OtherID
1 1 10
2 1 13
3 1 25

how do I join these two tables, such that I get all the otherID's for each DocID.
ie.,
DocID OtherID
1 2 and 10 and 13 and 25
2 3

i am writing this query to display search results on a search page (with keyword search) and so, if I display the result in more than one row, then the user might think that there is more than document...whereas the case is that there is only one document with more than one other ID's.

is there any way I can do this? display...more than 1otherID in the same row for the same DociD?
Currently, I am using a left outer join of table1 and table2.

An suggestions on how to do this?

Hi,

I need a way to retrieve records from a table with a 30 min interval between the records.

For e.g., Lets say I have the following data in a table :-

userid hitdt

1 4/1/2003 10:15 AM
1 4/1/2003 10:31 AM
1 4/1/2003 11:10 AM
1 4/1/2003 11:30 AM
1 4/1/2003 11:41 AM

I need a query which would return me the following recordset :-

userId hitId
1 4/1/2003 10:00 AM
1 4/1/2003 10:31 AM
1 4/1/2003 11:10 AM
1 4/1/2003 11:41 AM

Is there a way to do this without using a cursor ?

Complex Query Help

Jan 27, 2007

I might have to redesign the tables for this, but I'll ask anyway. I have a table with the following fields:

Email - VarChar
Seminar - Int
PeckingOrder - Int.

As I add addresses to the table, each one has a Seminar, and then each Seminar has a Pecking Order Value. If an email address shows up for more than one seminar, it can have multiple records. IE:

email1 - 1523 - 424
email1 - 1526 - 124
email1 - 1524 - 235
email2 - 1526 - 124
email2 - 1524 - 235

for address, seminar, and pecking order would be sample entries into the table. Give or Take 1000 records in the table at any given time. What I want to pull out is:

Distinct Email Addresses
For each Email Address - The Max(PeckingOrder)
And the Seminar that's associated with Max(PeckingOrder)

For the sample data set above, I'd want to see these two records returned by the query:

email1 - 1523 - 424
email2 - 1524 - 235

I can't seem to get the Having / Where clause right to pull those two records properly. Anyone have any suggestions?

Thanks,
--Daniel

Edited - Didn't realize the BB removed email addresses.

Need Help With A Somewhat Complex Query

Oct 10, 2007

Code:


SELECT
goto_last_name as 'Manager',
advisor_name,
advisor_ao_number as 'AO',
COUNT (CASE advisor_termination_date WHEN '<Null>' THEN 1 END) as '#Advisors',
SUM(Weekly_TOS_GDC) as 'TOS GDC'
FROM weekly_condensed_tb
WHERE advisor_platform_number = 1
AND report_date BETWEEN CAST(CONVERT(VARCHAR,'9/11/2007',112) AS DATETIME) -28
AND CAST(CONVERT(VARCHAR,'9/11/2007',112) AS DATETIME)
GROUP BY goto_last_name,advisor_ao_number,advisor_name
HAVING COUNT (CASE advisor_termination_date WHEN '<Null>' THEN 1 END) > 1



In the query above i select a range from the date - 28 days and do a sum on the TOS GDC column. What i am trying to do is have another query where the range will be - 56 and maybe - 86 so i get the SUMS for that as well. I need to display this in SQL Reporting Services and i can only have one DataSet returned otherwise i will not be able to bind it to one table.

How can i go about this so i return one set of data for 3 different date ranges.

Complex Query In Sp

Jun 2, 2004

I'm struggling with a syntax error in my sp. I'm hoping someone can give it a fresh look and straighten me out. Thanks.
Background:
1. The innermost query (using the dynamic statements) will run fine on its own.
2. I can wrap that in another query (with the innermost as a DERIVEDTBL) and it will run fine UNLESS I apply the GROUP BY. Then I get syntax errors.
3. Also, the entire query runs fine as a view (with hard coded vals for column and value).
4. I don't know what kind of formatting this message will apply, so just know that I've checked my line truncations and they all include a trailing '+. Also, I know that Occured is misspelled. That is the correct object name. Not all our DB admins are lit majors.

Here's the code:

CREATE PROCEDURE [dbo].[sp_ninetydayavgtotals]
@column nvarchar(100),
@value smallint
AS
DECLARE @SelectString nvarchar(500)

SET @SelectString = 'SELECT AVG(total_attacks) AS avg_attacks ' +
'FROM (SELECT TOP 100 PERCENT thedate AS [day], COUNT(total) AS total_attacks, SUM(enemyKIA) AS EKIA, SUM(enemyWIA) AS EWIA, SUM(coalitionKIA) AS CKIA, SUM(coalitionWIA) AS CWIA ' +
'FROM SELECT(TOP 100 PERCENT CONVERT(nvarchar, dateOccured, 11) AS thedate, txtCategory AS total, enemyKIA, enemyWIA, coalitionKIA, coalitionWIA ' +
'FROM dbo.v_maindata ' +
'WHERE (CONVERT(nvarchar, dateOccured, 11) > CONVERT(nvarchar, (getdate()-90), 11)) AND (CONVERT(nvarchar, dateOccured, 11) != CONVERT(nvarchar, getdate(), 11)) AND ' + @column + ' = @value ' +
'ORDER BY dateOccured DESC) DERIVEDTBL ' +
'GROUP BY thedate ' +
'ORDER BY thedate DESC) DERIVEDTBL'

EXEC sp_executesql @SelectString, N'@column nvarchar(100), @value smallint', @column, @value

Hi,
I want to create a query with which I must compare the production demands with the production results. The production demands can be get by the join of two tables. The production results can be get from an aggregate of 4 tables. The connection of these two objects rely on two fields that exist in both two objects. In order to show all the production demands I must left join the two fields from the demands object to the two fields exist in the aggegate production object. In MsAccess the only way to do it is to create 2 queries one for the demands and one aggregate for the production and in a third query create two left joins from the demands query to the production query and get the right results. How can I do it with MSSQL Server with a query??

Best Regards,
Manolis

DB Query (complex Maybe)

Mar 6, 2007

I have database like below.

BLOG
--POSTER_ID
--POSTED_BY (a FK refer to USERID)
--UPDATED_BY (a FK refer to USERID)


USER
--USER_ID
--NAME

I want to retrieve the info for all posts that posted and updated by different users, also the query returns both user names for every posted and updated action.

I can write two queries to do that

select B.POSTER_ID, U.NAME from Blog B inner join USER U ON B.POSTED_BY = U.USER_ID

select B.POSTER_ID, U.NAME from Blog B inner join USER U ON B.UPDATED_BY = U.USER_ID

Then write some code to combine the result for the posted and updated user name. But this is not efficient.

I am wondering how can I write one query to archeive that?

Thanks.

Complex Query

May 22, 2007

Hi Guys Hope you can help with this - it's certainly got me scratching my head. I'm Querying a Call Centre Database I have a Table of Call Data with a Start Time & End Time of the Call. (CallID,Started,Ended)10942086 2007-04-01 00:01:09.000 2007-04-01 00:11:31.0001003855355 2007-04-01 00:01:24.000 2007-04-01 00:01:24.00010942071 2007-04-01 00:01:25.000 2007-04-01 00:02:43.00010942271 2007-04-01 00:02:57.000 2007-04-01 00:05:01.00010942283 2007-04-01 00:05:54.000 2007-04-01 00:06:50.00010942079 2007-04-01 00:07:15.000 2007-04-01 00:07:46.00010942287 2007-04-01 00:07:30.000 2007-04-01 00:08:12.00010942289 2007-04-01 00:07:49.000 2007-04-01 00:08:33.000I'm trying to produce Stats that tell me how many Calls were live in any one given minute. Ultimately I will be producing a Line Graph of No of Calls Connected grouped by Minute. I've gone as far as creating a temp table with every minute in a month with the following query maybe to join to but not sure if this will help me. WHILE(@cnt <= 43200)BEGINSELECT @MaxDate =DATEADD(mi,1,MAX(DTBlock))FROM AprilMinutesINSERTINTO AprilMinutes VALUES(@MaxDate,NULL)SET @cnt = @Cnt +1 ENDWhich produces a nifty little table with 01/04/2007 00:09:0001/04/2007 00:10:0001/04/2007 00:11:0001/04/2007 00:12:0001/04/2007 00:13:0001/04/2007 00:14:0001/04/2007 00:15:0001/04/2007 00:16:00 If one individual Call Spans 2 minutes I'll count it as 1 in the first minute & 1 in the second minute. Overall I'm trying analyze how many telephone lines we need Any Help much, much appreciated Thanks GW

Complex SQL Query

Mar 31, 2004

Hi all,

I am developing an application using SQL Server as Back-end. I am facing a problem in creating a SQL Query. The details are as follows:

There are three tables in the Database, Data Type of all Columns is Numeric in all three tables:

1. T1

(column names and sample data)

en
==

1
2
3


2) T2


(column names and sample data)

en gn
== ==

1 10
1 11
2 10
2 12
2 13


3) T3

(column names and sample data)

en pn
== ==

1 20
1 21
1 22
2 20


Now I have to create a SQL Query, whereby I can get the following result:


en gn pn
== == ==
1 10 20
1 11 21
1 NULL 22
2 10 20
2 12 NULL
2 13 NULL


I have tried various combination of Joins, but unable to get the desired result as the tables have many-to-many relationships, therefore I get many duplicate rows in the result. UNION will not solve the problem, as that will add the additional rows for the third table. Although I can achieve this by writing few lines of code, but I have to create a SQL Query for getting this result. Kindly tell me the way for creating the required Query for this. Many Thanks for your help.

Complex Query

Apr 10, 2006

Table Name: Story
Table Columns: user_id, date, name, yr_left, city_origin, country_origin, yr_arrival, city_arrival, state_arrival, address, city, state, zip, AorV (audio or video), filename, approved

I need to create two queries. One based on date in descending order, and one based on country_origin in alphabetical order. For both of these queries, the approved field has to = Y for yes, and when I return results I need it to return everything in the table EXCEPT for the name.

I'm a beginner at SQL queries so I was hoping someone could shed some light and help me??? Thanks a bunch!

Complex Query (for Me)

Jan 24, 2007

Below are the two tables (with sample records) that I am trying to include into my query:

[Journal] (ID, EntryDate, Description)
1, 1/24/2007, Fred Meyer

[Journal_Splits] (ID, JournalID, AccountID, Amount, Type)
1, 1, 11, 19.95, 2
2, 1, 8, 24.99, 2
3, 1, 3, 5.49, 2

The AccountID refers to another account table that holds income and expense categories such as Groceries, Leisure, Clothing, Household, etc...

I want to create a query that will return the following:

[JE Query]
ID, EntryDate, Comment, Income, Expense


ID, EntryDate and Comment are all easily returned from the [Journal] table. The problem I am having is with the Income and Expense fields. For the Income field, I want to SUM the Journal_Split.Amount fields where Journal_Splts.JEID = Journal.ID AND where Journal_Splits.Type = 1 (1 being the code for Income). The Expense field is just the same, except the Journal_Splits.Type will be equal to 2. When the query is done there should only be as many rows as there are in the [Journal] table, for the [Journal_Splits] table can contain up to 3 records for each [Journal] record. [Journal_Splits] just holds the individual amounts split out to different income/expense categories for a single transaction.

This to me has a lot of conditions that I can't even seem to build with access's query builder (yes I am using access for now.. will change over to sql at a later time).

Anyone have a good idea how to do this? Or have a better idea for structuring the database to make is easier to query? Right now I have it working, but instead of an Amount field, I have 1 Income and 1 Expense field, but since a transaction can only be either income or expense, one field will always be 0, which seems like a waste of space.

That may be a bit confusing so let me know if I can clarify. Much appreciated.
