Hi all,
I have a table with the following fields:
carrier,calc_date,ind_id,rcf
I need to run a query to get the following result(by carrier and for each calc_date, calculate the percentage of all individuals who have rcf greater than 0.73):
carrier,calc_date,count of ind with rcf > 0.73, count of all individual, percentage of individuals with rcf's greater than 0.73.
does anyone have an idea of how to achieve that result?
Thanx

I have table A which has and accountid,df_date1,df_date2. The table is a demographic one which has 1 record for each account
I have a table B which I need to populate from the first df_date1 fields in table A. Table B which is normalized and has an accountid and a df_date1 field but may have several records per accountid. I need the max(date) from this table. I wanted to do an update statement like below
update A
set df_date1
= max(df_date1) from b
where a.account_id = b.account_id
I get the error message
Server: Msg 157, Level 15, State 1, Line 3
An aggregate may not appear in the set list of an UPDATE statement.
Is there another way to do this with a subselect and update?
Hi all...
how I can obtain the sum of a datetime field as aggregate function?
Given a set of records I need to calculate the number of records (count (*)) and the sum of a field of type datetime.
Is this possible? how?
Thanks..

The actual schema I'm working against is proprietary and also adds more complication to the problem I'm trying to solve. So to solve this problem, I created a mock schema that is hopefully representative. See below for the mock schema, test data, my initial attempts at the query and the expected results.
-- greatly simplified schema that makes as much sense as the real schema
CREATE TABLE main (keyvalue INT NOT NULL PRIMARY KEY, otherdata VARCHAR(10));
CREATE TABLE dates (datekeyvalue INT NOT NULL, keyvalue INT NOT NULL, datevalue DATE NULL, PRIMARY KEY(datekeyvalue, keyvalue));
CREATE TABLE payments (datekeyvalue INT NOT NULL, keyvalue INT NOT NULL, paymentvalue INT NULL, PRIMARY KEY(datekeyvalue, keyvalue));
[Code] ....
Desired results:
SELECT 1 AS keyvalue, 'first row' AS otherdata, '2015-09-25' AS nextdate, 30 AS next_payment
UNION ALL
SELECT 2, 'second row', '2015-10-11', 150
UNION ALL
SELECT 3, 'third row', NULL, NULL
I know I'm doing something wrong in the last query and I believe another sub-query is needed?
Let me answer a few questions in advance:
Q: This schema looks horrible!
A: You don't know the half of it. I cleaned it up considerably for this question.
Q: Why is this schema designed like this?
A: Because it's a 3rd-party mainframe file dump being passed off as a relational database. And, no, I can't change it.
Q: I hope this isn't a frequently-run query against a large, high-activity database in which performance is mission-critical.
A: Yes, it is, and I left out the part where both the date and the amount are actually characters and have to pass through TRY_CONVERT (because I know how to do that part).

I am trying to exclude records that have an assessed value that has been waived in an aggregation. For Example:
Here is my table:
CREATE TABLE #temptable (ReportingMonth Varchar(6), Fee_Code Varchar(20), Fee_Transaction_Amount Decimal(12,2), Fee_Transaction_Date Datetime, Fee_Transaction_Type Char)
INSERT INTO #temptable (ReportingMonth, Fee_Code, Fee_Transaction_Amount, Fee_Transaction_Date, Fee_Transaction_Type)
SELECT 'Jan-13', 'ONE TIME DRAFT FEE', '20', '01/24/2013', 'A'
UNION ALL SELECT 'Feb-13', 'LATE CHARGE', '33.6', '02/19/2013', 'A'
UNION ALL SELECT 'Mar-13', 'LATE CHARGE', '37.01', '03/18/2013', 'A'
[code]....
Here are Data Mapping Description
Reporting Month = Month - Year
Fee Code = Fee Description Name
Fee Transaction Amount = Fee Amount
Fee Transaction Date = When Fee Amount was Applied
Fee Transaction Type = "A" = Assessed Fee; "W" = Waived Fee; "P" = Paid Fee
I've also included an image with beginning data set and what I want to identify in red and what my final data set should look like after the exclusion of those 4 records are removed.
Here are the logic requirements:In the attachment what I need the logic to do is essentially identify the $20 One Time Draft Fee from the first instance using the MIN Transaction date. Since there were $80 waived for this fee code (One Time Draft Fee), I would expect to see the first 4 (highlighted in red) to be identified as the target and as you can see in the attachment the second data set had the 4 highlighted items removed. That should be my final output.
trying to loop and remove the waive amounts from the assess amounts and tied it back to remove from my base data.
I am using SSRS 2014. I'm using a matrix instead of a tablix because it allows me to have dynamic columns. In the example I'm showing, two of the columns use the sum function to get the total counts per practice. The third column contains percentages so I averaged for the total but the value is inaccurate compared to the value I would get if the divided the the two totals that are sums of the counts. Is there a way for me to specify that I want to divide the total counts numerator divided by the total counts denominator?
Here's an example report output with the percentage column averaged (inaccurate):
PCP Â Â Â Â Â Â numerator denominator percentage
John Smith  66       104 63.46
Tom Jones   4         36   11.11
.
.
.
Jane Doe    1   1     100
Total 708 Â Â Â Â Â 1005 Â Â Â Â 72.3
So the 72.3 value is from Avg(metricvalue)
I would like to do this instead: % total = 708/1005, which equals 70.5 - a significant difference.
The metricvalue column is what is the value for every number above (Because it's a matrix).
Can any1 tell me why i am getting an error

I need to get the sum of a field that already has an aggregate function (MAX) performed on it. I am using the following query
Code Snippet
SELECT "tI"."ItemID", MAX("vSS"."ShortDesc") "Short Description",

Hi,
I have we have a client who gives their invoices in a flat file format, we import it into a SQL Server table.
Nothing is normalized – everything is repeated in every record. The fields are:
customerNumberInvoice_numberPO_numberQtyDescriptionLine_numberLine_totalFreightTaxInvoice_date
So an if an order has 10 line items, the header information (invoice number, PO number, ivoice date) are repeated on each of the lines
I am writing a query to show the following
Order number, Invoice total, Date
select invoice_no, sum(line_total + freight + tax) as invoiceTotal, customerNumber, Invoice_date from invoices group by invoice_no, Invoice, customerNumber
This works great - for each invoice I get the invoice number, InvoiceTotal, and Date
Then I was asked to add the PO Number – this is where I can’t get it right.
When I added “PO_number� to the query, I got two lines for each invoice
select invoice_no, sum(line_total + freight + tax) as invoiceTotal, customerNumber, Invoice, PO_number from invoices group by invoice_no, Invoice, Sold_To_Cust_No, PO_number
Please help - I need to end up with: invoice_no, invoiceTotal, customerNumber, Invoice_date and PO_number (sequence does not matter)
Thanks

I have a table that is used for employee evaluations. There are six questions that are scored either 1, 2, 3, 4, or 5. I want to tally the responses on a page, but I wonder if I can do it without 35 separate calls to the database (I also want to get the average response for each question). I know I can do "SELECT COUNT(intWorkQuality) AS Qual1 FROM dbo.Summer_Project_Req WHERE intWorkQuality = '1' " and then "SELECT COUNT(intWorkQuality) AS Qual2 FROM dbo.Summer_Project_Req WHERE intWorkQuality = '2' " and so on. But can I somehow do the aggregating at the page level, and just refer back to a datasource that uses a generic statement like "SELECT intWorkQuality, intDepend, intAnalyze, intWrite, intOral, intCompatibility FROM dbo.Summer_Project_Req"? If I can, I am not sure what type of control would be best to use or what syntax to use to write the code-behind. I would like the results to be displayed in a grid format. Thanks in advance for your help.

View 3 Replies View RelatedWhat I'm trying to solve:
I have an application that generates SQL queries, and sometimes uses
DISTINCT where the result set has no dupe rows. In terms of database
resources, I'm trying to figure out if it's worth it to change to app to be
smart enough to not use DISTINCT where it won't serve any purpose, or
whether to let it do the DISTINCT and save added complexity to the query
building application. I.e. what is the cost of DISTINCT where there are no
dupe rows?
What I want to know:
Can someone explain how the stream aggregate operator actually goes about
doing its work?
Does this always create a temp table for sorting and discarding duplicates
(for DISTICNT)? If the answer is "no or sometimes", how does it do so in
the case where a temp table is not involved? I noticed the the estimated
I/O for this operator was zero for some queries I wrote agains pubs. Does
this mean that the optimizer believes the temp table needed will fit
in-memory and creates it in-memory? Or does the estimated I/O figure not
included disk writes for work tables?

Hello,
I was told that on Oracle there's something called an Aggregate Navigator which should be capable of changing the table you're addressing in a query to another table (with aggregate data) and in this way optimize performance in a data warehousing environment.
Is there anything similar in MS SQL Server?
MS Access provides FIRST and LAST aggregates to select the first and last values from a group.
These aggregates apparently do not exist in TSQL.
I am after a workaround for the lack of these aggregates.
Any advice would be appreciated.
Hi, I am wanting to query the identifier field via the MAX function.
eg.
need to retrieve the BookID of the greatest Book Price
Code:
SELECT BookID,MAX(BookPrice)
FROM Book
this errors, with:
Column 'BookID' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.
I realise there are other ways such as referencing back on the same table eg.
Code:
SELECT BookID FROM Book WHERE BookPrice = (SELECT MAX(BookPrice) FROM Book)
but was hoping would be a more direct way, is there a specific direct use of MAX for this purpose or another SQL command?

I'm hoping for a little insight for a novice.
Here's what I have:
1 table that looks like this...
Code:
rep_id answer
1 2
1 1
2 1
3 0
3 1
3 1
4 2
What I want is a recordset returned as ... (columns that tally the 1s and 2s respectively with the rep's id#)
Code:
rep_id total1 total2
1 1 1
2 1 0
3 2 0
4 0 1
What I can do so far is get individual recordsets returned for either total1 or total2 but not together.
Here's what I'm using for these...
Code:
SELECT rep_id, COUNT(answer) as total1
FROM myTable
WHERE answer = '1'
GROUP BY rep_id
and
Code:
SELECT rep_id, COUNT(answer) as total2
FROM myTable
WHERE answer = '2'
GROUP BY rep_id
So how do I form a SQL statement that will combine the 2 columns I have created into 1 joined by the rep_id?
To make it a little stickier there may be some nulls in the existing answers but hopefully that is not going to bung me up.
Any help will be thankfully received!!!

I need to find an aggregate for several fields in a row

I can pass this to a delimited string,
pass the string to an UDF that returns a table

Hai frns small help needed.
I have a table called sample and i have the following requirement. i.e i need sum(credit) group by ssn no.
One special condition is as follows:
For each distinct ssn if "flag" has the same CX value,then out of all the records with the same CX value, the highest "credit" value is added to the sum for that "ssn" and the rest are ignored.
If while adding "credit" to the sum and if "credit" value is equal to zero then "sum" value is used for summing else "credit" value is used.
Can any one help me out in trying this logic. I have tried but i could'nt able embed the conditions inbetween the Sql statetment.

select ssn,flag,sum(case credit when 0 then sem else credit end) as sum from sam2
group by ssn,flag
ssn flag sum_val
101C13.5
103C12.0
102C34.2
101C98.5
The above output is wrong one.
Expected output
101 4.5+3.5=8.0
102 4.2
103 2.0
Any help would be appreciated
Regards,
I have implemented a login audit on a particular system which catches the users login details, including their application logon name and NT username.
What I want to do is report on users who have logged on to the software using someone else's workstation (i.e. logged on to more than one workstation).
Here's some sample stuff to play with
DECLARE @logins table (
loginName char(20)
, ntUsername char(25)
, loginDate datetime
)
--Insert test data. Please note that loginName and ntUsername are rarely the same
INSERT INTO @logins (loginName, ntUsername, loginDate)
SELECT 'Amy', 'Amy', '20070101' UNION
SELECT 'Amy', 'Amy', '20070102' UNION
SELECT 'Amy', 'Amy', '20070103' UNION
SELECT 'Bob', 'Bob', '20070101' UNION
SELECT 'Bob', 'Bob', '20070102' UNION
SELECT 'Bob', 'Amy', '20070103' UNION --Bob has logged on using 2 different NT accounts
SELECT 'Cal', 'Cal', '20070102' UNION
SELECT 'Cal', 'Amy', '20070102' UNION --So has cal
SELECT 'Dom', 'Dom', '20070102' UNION
SELECT 'Dom', 'Dom', '20070102'
Any ideas? I just can't think of the logic needed to get what I want.
Any extra info needed - just ask!
Cheers
This query not start, why?
Code:
[SQL] SELECT
DTZZ,
[NUM],
[ENER],
MAX ([MYDATE]) AS max_date
[Code] .....
[Err] 42000 - [SQL Server]An aggregate may not appear in the WHERE clause unless it is in a subquery contained in a HAVING clause or a select list, and the column being aggregated is an outer reference.
Hi
I have a query where I need to use an aggregate function MAX in where clause, I know that MAX cannot be used in a Where clause because it is an aggregate function. Can anyone help me out in writing this query?
SELECT * FROM ACCOUNT_REVIEW AR INNER JOIN
QUESTION_RESPONSE ON
AR.Review_ID = QUESTION_RESPONSE.Review_ID
WHERE (MAX(AR.Review_Date) IS NULL)
I need it asap. Thanks in advance,
K
