How do I output a row number for a table solely for the purpose of
querying for a unique row?
In my problem, the table from a legacy system does not have a primary
key, so it limits various querying I'd like to do that identifies
uniqueness in the table.
The problem is that since I'm using DTS to simply copy the table to
SQL, I don't want to create identity rows.
Ok,I just need to know how to get the last record inserted by the highestIDENTITY number. Even if the computer was rebooted and it was twoweeks ago. (Does not have to do with the session).Any help is appreciated.Thanks,Trint

How to calculate the overall average number of days taken to complete something.
The two fields are enquiry_date (date enquiry is recorded) and complete_date (date enquiry completed/closed).
Each enquiry has a enquiry_number
Sample data typically looks like:
Enquiry number - enquiry_time - complete date
1 - 01/01/2014 - 12/01/2014
2 - 01/01/2014 - 11/01/2014
3 - 01/01/2014 - 10/01/2014
4 - 01/01/2014 - 07/01/2014
5 - 01/01/2014 - 12/01/2014
6 - 01/01/2014 - 04/01/2014
etc.
What is the piece of SQL which looks at the average date difference for each enquiry and then sums it all up to give an overall average number of days it takes?
I've got a string of numbers, say 123456 (the actually number is 12 digitslong). I need to calculate the sum of each individual number in the stringof numbers, so in the example of 123456 the sum would be 21 (1+2+3+4+5+6).Thanks
View 5 Replies View RelatedHow to write a query that calculate the number of days (approx) that it takes to a customer to pay an invoice.
Document Types
1 Payment
2 Invoice
3 Credit Memo
4 Finance Charge Memo
5 Reminder
6 Refund
There are three methods to consider when calculating the days to pay logic.
Method 1 - Simple : Look for Document Type 2 (Invoice), if "closed at date" > "posting date" then number of days = ("closed at date" - "posting date")
Method 2 - A Document Type 1 (payment) closes a Document Type 2 (Invoice)
For this method the formula would be: Payment Record (1) "posting date" - Invoice Record (2) "posting date"
Method 3 - An Invoice closes the payment.
On a payment entry “closed by entry no.” refers to an Invoice entry.
a. In our code we are not on the payment looking for the invoice, we are on the invoice.
i. Because of this we need to find the entry that our current invoiced has closed.
I am taking this from a page that has the pascal code that I need to translate to SQL.
IF (CustLedgEntry2."Document Type" = CustLedgEntry2."Document Type"::Invoice) AND
NOT CustLedgEntry2.Open
THEN
IF CustLedgEntry2."Closed at Date" > CustLedgEntry2."Posting Date" THEN
UpdateDaysToPay(CustLedgEntry2."Closed at Date" - CustLedgEntry2."Posting Date")

If we see at the data above Test has 2 rows because he changed his specialty in the middle.My requirement is to calculate the total number of employees in each month for last 2 years in each speciality. For example if we look at the example above, Test was in Inside property from 2009 Aug to 2010 Aug but if i use just the date start and take the month for each adjuster it gives me the number of adjusters started in that year and month but what i want is Test should be counted in all the months for Inside property until 2010 07 month. Which means i want to have the total number of adjusters present by each speciality for each month of last 2 years .

Aim – Calculate the number of days between the [CreatedDate] and getdate, however if stage name = ‘Live Transactions’ then Calculate the number of days between [CreatedDate] & [CloseDate]
This is my query so far
SELECT [CreatedDate]
,[StageName]
,[CloseDate]
,DATEDIFF(dd,CONVERT(datetime,[CreatedDate]),GETDATE()) as Age
FROM [FDMS].[Dan].[Raz_Reporting_LCS]
Which produces the following
CreatedDate2012-12-17
StageNameLive Transactions
CloseDate2012-12-31
Age424
When in fact the age should be 14days
I have a requirement to calculate the % change in the number of orders received today with the number of orders that were received 3 days back. All data is in the same table. There is a received date column.
I have two count(*) queries - one for today and one for 3 days back running separately and getting the results. Is it possible I can get the % change in orders received from 3 days back and today in one query.Also if I want to get the number of orders received today between 12:00am today and current time. How would I modify the query.
Hi,
I need to calculate the number of working days from a date backwards. For example 2 working days before Thursday would be the Tuesday (as a basic example)
I use the following code and a Calendar table to calculate the working days from a date but can anyone help with reworking this query to do the reverse
declare @WorkingDate as datetime
SELECT @WorkingDate=dt

WHERE (dt >= @StartDate) AND (dt <= c.dt) AND (IsWeekday = 1) AND (IsHoliday = 0))) AND (IsWeekday = 1)
AND (IsHoliday = 0)
-- Return the result of the function
RETURN convert(varchar(12),@WorkingDate,106)
Hope someone can help

I am looking for a formula to calculate the number of weekdays/business days between two dates in power pivot.I do the same in SQl using the following query
DATEDIFF(dd, Date1, GETDATE()) - (DATEDIFF(wk, Date1, GETDATE()) * 2) -
CASE WHEN DATEPART(dw, Date1) = 1 THEN 1 ELSE 0 END +
CASE WHEN DATEPART(dw, GETDATE()) = 1 THEN 1 ELSE 0 END END

Our fiscal year starts on July 1st. Each month they call a period - so July is period 1, August is period 2, etc.
They are wanting a report that pulls numbers for a given period. There are parameters for them to select the fiscal year and the fiscal period, and then it calculates the numbers for that period. That part works fine.
Now they want me to do some calculations, and one of them is to divide one of the numbers by the # of days since the fiscal year. So if they choose July, it would be 31 days. If they choose August, it would be 61 days, etc. How can I set this up to calculate the number of days when they really aren't entering a start date, it's just a fiscal year and period.
Is there a way to calculate a date field that is 07/01/xxxx where xxxx is the fiscal year they chose? Also a way to calculate a date field that would be the last date of the month for the fiscal period and year they chose?
I suppose I could add 2 other parameters where they enter the start of the current fiscal year, and the last day of the period they're running it for, and use a datediff to calculate that. Just seems kind of redundant.
I have a challenge and I'm not sure the best route to go. Consider the following dataset.

CustomerNumber SalesDate

1234 02/20/2011

I need to calculate the last two columns (noofgrp and grpsize) No of Groups (count of Clientid) and Group Size (number of clients in each group) according to begtim and endtime. So I tried the following in the first Temp table
GrpSize= count(clientid) over (partition by begtime,endtime) else 0 end
and in the second Temp Table, I have
select
,GrpSize=sum(grpsize)
,NoofGrp=count(distinct grpsize)
From Temp1
The issue is for the date of 5/26, the begtime and endtime are not consistent. in Grp1 (group 1) all clients starts the session at 1030 and ends at 1200 (90 minutes session) except one who starts at 11 and end at 1200 (row 8). For this client since his/her endtime is the same as others, I want that client to be in the first group(Grp1). Reverse is true for the second group (Grp2). All clients begtime is 12:30 and endtime is 1400 but clientid=2 (row 9) who begtime =1230 but endtime = 1300. However, since this client begtime is the same as the rest, I wan that client to be in the second group (grp2) My partition over creates 4 groups rather than two.

I am a student, and I am so confused by SQL code that calculates incomes of my contract in a year or each month of year.
I have 3 tables:

day_begin datetime,
day_end datetime,
day_register datetime
money_per_month money

Water:
id_Water indentity primary key,
id_room varchar(4),

number_last int,
Sum_Number int,
money_water money,
status bit
Now what I want to do are statistics on how much money I got in a year or month. Here is my code to calculate incomes of year.
Select Year(day_register) as 'Year'
, Sum(money_per_month * month(day_end-day_register)) + sum(b.money_electric+c.money_water) as 'Incomes'
From lodgings_Contract a
, electric b
, Water c
Where a.id_room = b.id_room
And a.id_room = c.id_room
And b.status = 1
And c.status = 1
Group by Year(day_register)
Is there a function or a code that I can use to get the value of the next Identity column number?? (the auto incrementing column)
thanks a lot!
hi.i am using ms sql server 2000. can somebody tell me what the code would be to remove all the values in a given column and replace them with the associated number of the row with each execution. so, if i have a column:nums|1||2||3||4|and somebody deletes record |2|i would like the nums colum to update to|1||2||3|not:|1||3||4|it seems simple but i am having a hard time with this. how is it done?thanks.
View 14 Replies View RelatedAll of my tables in my database have keys that are autonumbered (datatype int with identity set to 1).
Whenever I go to insert a new entry into the table I execute an INSERT INTO command and leave off the key field, so that it is automatically inserted with the new row.
However, I need to that number, so that I may insert it as foreign key into another table. How would I go about retrieving this number? I thought about doing a Max() on that field, but I am not confident that SQL server would always use a higher number than everything previous. Is there a better way of accomplishing this? Is my design flawed from the start? Any feedback would helpful. Thank you.
Hi,
I have the following two tables:
Code:
create table RECORD
(
ID int not null,
Issue_descr varchar(256) not null,
Priority varchar(5) not null,
Status varchar(12) not null,
Date_add varchar(10) not null,
Date_due varchar(10) not null,
Date_complete varchar(10),
PName varchar(32),
primary key(ID),
foreign key(PName) references PROJECT(PName)
);
and
Code:
create table STEPS
(
ID int not null,
Num int not null,
Descr varchar(256),
Date_due varchar(10) not null,
Date_complete varchar(10),
Status varchar(12),
primary key(ID, Num),
foreign key(ID) references RECORD(ID)
);
I have set PK "ID" in table RECORD to auto identity(1,1). I have done the same for PK "num" in table STEPS.
However I am seeking this behavior in STEPS:
ID num
-- ----
19 1
19 2
19 3
20 1
20 2
21 1
but what I'm getting is PK num doesn't "reseed" or reset to 1 as "ID" changes. PK num just auto-increments regardless of ID. Is there a workaround?
Thanks.
I am migrating a web application I wrote from ASP to ASP.Net, and fromAccess to MS SQL server.In the Access version, I did not use the auto number for creatinginvoices and other documents, because I heard somewhere (perhapsincorrectly) that if the db was ever compacted or otherwise changed,it could change the values of the auto-numbers. Not a good thing.So I wrote a routine that, just before creating a new record, wouldlook for the highest value in the table and create the new record withthe next number.So my question is, am I safe in assuming that in MS SQL that I can seta starting number for the next, let's say, invoice and that newnumbers will be issued in sequence, and that these numbers will neverchange? What happens if an invoice is deleted? is the number goneforever? Just wondering how others deal with these issues...thanks.Larry- - - - - - - - - - - - - - - - - -"Forget it, Jake. It's Chinatown."

Hi ,,
How to write the Sql Query to return the next generated Identity from the Sql server database.
I am attempting to import data from a Lotus Notes database using DTS. The SQL table I am importing to has an identifying auto-number. I can't insert directly into it because the SQL server should, however I get an error if I ignore it in the DTS package. Is there any way to get around this?
View 4 Replies View RelatedTable structure: col1 IDENTITY (seed=1 increment=1) + few other columns (col2...col7) + one text column (col 8)
I have around 50,000,000 rows per day inserted in the table T1. At the end of the day 40,000,000 rows are deleted. I have to keep the records for 12 months and then archive it. Database is 24/7 web serving and there is no down time allowed. IDENTITY column will go out of range (overflow) after less than two years, unless the identity seed is reset to the start value (seed=1, increment=1).
At the end of 12th month data is archived in another table and only last month is kept in the table T1. So table T1 enters new year with data from last month of the previous year. There are few other tables that refer to this table by using there own field with values from T1.IDENTITY column (referential integrity is not enforced). Identity column in T1 is needed as a unique id for some search actions. Performance is an issue therefore bigint data type is used for this identity column rather than decimal.
Another problem I have is how to do table update on one column (1 mil rows to be updated out of 2 mil of rows) with the minimum impact on the users who are querying this table heavily. Not need to mention that it is web app 24/7 no down time.
Thank you in advance.

Hi. I am trying to figure out the code for sorting a manual (non-identity) number column in my table. the purpose is to
show the user's pictures in perfect order (1,2,3,4,5,6...).
The Jist of my problem... When a user first inserts six pictures, he gets:
|1|
|2|
|3|
|4|
|5|
|6|
All is good. But, say he deletes picture |3|. Now the list order looks like this:
|1|
|2|
<- |3| is removed
|4|
|5|
|6|
And, then he inserts two more pictures, now he his this:
|1|
|2|
|4|
|5|
|6|
|7| <- |7| & |8| are added
|8|
What i want to acheive is a "reshuffling" of the number order every time a picture is removed. So, when |3| is removed, |4| becomes |3|, |5| becomes |4| and so on. There should never be a gap in the order.
I am new to stored procedures, and have been trying to figure this out. Below is my guesswork:
Code:
ALTER PROCEDURE dbo.sp_NewPersonalPic
(
@photo_name VARCHAR(50) = NULL,
@photo_location VARCHAR(100) = NULL,
@photo_size VARCHAR(50) = NULL,
@user_name VARCHAR(50) = NULL,
@photo_caption VARCHAR(150) = NULL,
@photo_default BIT = NULL,
@photo_private BIT = NULL,
@photo_number INTEGER = NULL,
@photo_date DATETIME = NULL
)
AS
BEGIN
SELECT @photo_date = CONVERT(DATETIME,convert(char(26), getdate(), 109))
END
BEGIN
SET @photo_number = 1
SELECT
@photo_number = (
SELECT COUNT(*)
FROM dbo.PersonalPhotos b
WHERE
a.photo_date < b.photo_date
)
FROM
dbo.PersonalPhotos a
ORDER BY
a.photo_date
END
BEGIN
My thinking is that it would be a safe bet to use the "photo_date" column as a litmus for my "photo_number" column (ie, the most recent record inserted by the user will always be at a later date than the previously inserted record). So:
photo_number photo_date
|1| 2006-06-26 21:43:36.653
|2| 2006-06-26 21:43:50.000
|3| 2006-06-26 21:45:25.217
|4| 2006-06-26 21:45:33.763
|5| 2006-06-26 22:39:42.670
|6| 2006-06-26 22:39:49.200
If |3| is removed above, the numbers are reordered based on the time of entry sequence.
Any suggestions on how to acheive this in my stored procedure? Currenly, i get the correct order, but it goes crazy when i delete and add.
Thanks and sorry for the verbose post.
