ps Id only want to work out how many years old they are. si!
Hey all! First post-- I apologize for the newbness of the question, but I'm having an issue with a basic query... here goes:
I want to calculate the percentages of statuses found from two tables. Let say T1 is my list of statuses:
T1
Passed
Failed
Not Completed
and T2 is the table where I derive my total # of statues for each id and how many in each status.
T2
ID, Desc, Status , numtimesinstatus
1, Test1, Failed, 3
1, Test1, Passed, 1
3, Blah, Failed, 5
3, Blah, Not Completed, 1
What I'd like to do is get the percentages for each available status in T1, from T2-- I can do this; however, I'm having trouble in the cases where a particular ID hasn't been in one of the status (in other words, calculating a 0%). What I'd like to get from these two tables is:
Result
ID, Desc, Status, %age
1, Test1, Failed, 75.0
1, Test1, Passed, 25.0
1, Test1, Not Completed, 0.0
3, Blah, Failed, 83.3
3, Blah, Passed, 16.67
3, Blah, Not Completed, 0.0
Can anyone shed some light? Thanks!
Hello there. I've been debating the best way to store the age of a ticket in a queue. Here's a little overview:
The application has a form that has users enter the current count and oldest ages of tickets in several queues. The format in the application they pull this data from stores it as Day:Hour:Minute (0:04:59)
The first time around, I stored them as datetime. But since you can't store a Day as zero (some tickets may be 0 days, 23:54 Hours old) I stored the day as a year. Well that proved to be stupid, because the averages in reports were way off. Next I stored the age as text, like this: 10459 (1 Day, 04:59 Hours old). Now my problem is when using that number in a report, I have to convert it to decimal and multiply the day by 24 and add it to the hour, just so they will be weighted correctly.
This is a mess... and I've searched all over the internet for examples, but every search result is for storing a persons age, not the age of a ticket.
Any one have any ideas?
Hope someone can help me with this because its driving me potty!
I have a .NET script that sends really simple queries to SQL server that works perfectly 50% of the time but for the other 50% it takes ages (2-3 minutes) and then fails, I'm assuming because it times out. I then check the SQL by excecuting it via query analyzer and it again takes ages but will work eventually (I'm assuming because this bypasses the timeout settings, but changing these isn't on).
This happens randomly, the scripts will be working fine and then fail a few times before magically working again!
Any ideas? Perhaps some database features that commonly cause this problem? The problem only occurs with one database, all our others are fine but we can't spot any differences!
Any help or tips would really be appreciated.
Thanks.
On SQL 2012 (64bit) I have a CLR stored procedure that calls another, T-SQL stored procedure.
The CLR procedure passes a sizeable amount of data via a user defined table type resp.table values parameter. It passes about 12,000 rows with 3 columns each.
For some reason the call of the procedure is verz very slow. I mean just the call, not the procedure.
I changed the procdure to do nothing (return 1 in first line).
So with all parameters set from
command.ExecuteNonQuery()to
create proc usp_Proc1
@myTable myTable read only
begin
return 1
end
it takes 8 seconds.I measured all other steps (creating the data table in CLR, creating the SQL Param, adding it to the command, executing the stored procedure) and all of them work fine and very fast.
When I trace the procedure call in SQL Profiler I get a line like this for each line of the data table (12,000)
SP:StmtCompleted -- Encrypted Text.
As I said, not the procedure or the creation of the data table takes so long, really only the passing of the data table to the procedure.
I want to sum up a column, but only summing up the top 25 quantites and then I want to subtract the sum of all quantities from the total of the top 25...how would this be done with t-sql?

I am interested in your opinion on the creation of primary keys in a table - simple ones that is. It would be the replacement for an Identity column.
Some say calculate the value off a lookup table, others say use an external object like c++ dll reading/incrementing from a flat file.
Using an identity column reduces portability of the table.
Thoughts ?

Hi,
What the best way to calculate the age given two datetimes.
I tried using the DATEDIFF(yyy,startdate,enddate) but that seems to only compare the year and not look at the specific day.
I am looking for something that would return the following output
birthday= 12/6/1973
EndDate = 11/30/2001
then the age should be 27
If birthday = 12/6/1973
enddate = 12/11/1973
then the age should be 28
thanks in advance

I'm in the process of developing a Kimball-method CRM data warehouse and I'd like to have Recency, Frequency, Monetary "scores" at the customer level. Am I better off creating these in the relational database and feeding them to SSAS or have SSAS do the aggregations and assign the "scores"?
Also, has anyone located any SSIS transform scripts that would calculated RFM scores? This is probably a pretty easy task in VB.net but I haven't gone down that road yet.

View 5 Replies View RelatedI needed to come up with an algorithm to create unique user- friendly account numbers such as AC0000000001, AC0000000002, etc...Where they increment by 1. I created a SQL function that retrieves the previous number generated, adds 1 to it, inserts the new value into the table, then returns the new value. I started thinking, what if the function is ran at the same time? What if function # 1 creates the new number, and function #2 creates a new number as well before function #1 inserts it? Is this a possible scenario? If so, how do I lock the process until the function completes to prevent this? Thanks for any help you provide.

First off, let me state that i am new to ASP.net... and have had to hit the ground running... I have looked on the net but have not found a suitable explanation on how to do this.
Let me explain what i am trying to do: In my aspx page, i have 2 dropdown boxes where the user will select a skill catagory, and then a skill. Based on that selection, i would like to compute what the Service line will be. There is a primary and foreign key on CatID on the skills and SkillCat tables. This data would need to be inserted into the another table aswell, and this would need to go into a report later.
How do i go about doing this? Some examples would be greatly appreciated. And if you know of a good link, please post it for me.

Hi,
I'm fairly new to MS SQL, but I'm trying to query the time elapse between two dates. Example below...
Select
dbo.res.book_date,
dbo.res.arrive_date,
Cast (dbo.translog.systemdate as datetime)
From
dbo.res
Where
dbo.res.resid > '500'
The third line is where I need help with a statement. I need the elapse time. Ex. if the book date is 20050820100000 and the arrive date is 20050820120000, I would like the third Select statement to return 2:00 hours or something similar. Thanks.
Hello,
I am fairly new to this, but I need to write a query that calculates whether an order made a shipping cutoff based on creation time, and when it actually shipped, based on local customer time. All times in the table below are central time.
Heres where it gets complicated for me. If the order was created after 8:00am local customer time the same day, and shipped prior to 5pm local customer time, it would be considered a pass, or a 1. If an order was created after 8am local customer time, BUT didnt ship until AFTER 5pm local customer time, it would be considered a failure or a 0. And to complicate things even more, if the order is created after 5pm local customer time, the order create time would be treated as it was created at 8am local customer time the following day local customer time, and would need to be shipped prior to 5pm local customer time that day. Would CASE be appropriate for this? Or am I thinking wrong? Any help would really be appreciated!!

Hi All,
I have a table that of server names and their execution times that run in to hundreds of thousands of records. What i need is some SQL that gives me the median execution times for each of these different servers. At the moment i have some SQL that only gives me the median for all the records in the table not the median execution time for every different server name. For example my tables looks something like this;
ServerName | ExecTime
-----------------------
server1 | 0.07
server2 | 0.17
server1 | 0.27
server1 | 0.37
server2 | 0.47
server1 | 0.57
server1 | 0.67
server2 | 0.77
My SQL below gives me
ServerName | ExecTime
-----------------------
server1 | 0.37
Where as i want
ServerName | ExecTime
-----------------------
server1 | 0.37
server2 | 0.47
Here is my SQL, hope someone can modify it and thanks in advance.
Code:
SELECT DISTINCT instance, exec_time AS median
FROM (SELECT instance, exec_time
FROM (SELECT TOP 1 exec_time = exec_time * 1.0, instance
FROM (SELECT TOP 50 PERCENT exec_time, instance
FROM llserverlogs
ORDER BY exec_time) sub_a
ORDER BY 1 DESC) sub_1
UNION ALL
SELECT instance, exec_time
FROM (SELECT TOP 1 exec_time = exec_time * 1.0, instance
FROM (SELECT TOP 50 PERCENT exec_time, instance
FROM llserverlogs
ORDER BY exec_time DESC) sub_b
ORDER BY 1) sub_2)
I have a table in my sql server that calculates renewal dates for me, that date is based on the final suit date. The table has the ssn, and the FinalSuitDate its in a one to many relationship with the employeetable.
the Finalsuit table is suppose to calculate the renewal dates(which I'm trying to do in a query) my original expression in access was using dateserial FirstRenewal: DateSerial(Year([FINALSUITDONE])+2,Month([FINALSUITDONE])+1,Day([FINALSUITDONE])=30), but sql does not recognize that.
For Example
If the Finalsuit is 12/01/2000
then the renewal would be 12/31/2002
the renewal are to be done on the last day of the month and two years from the finalsuit date. Problems is I'm having problems doing this in sql servers query?

Hi All,
I have a very complicated project and for some reason I have decided to use SQL server as the backend database. I am new to it and have encountered my first problem. In basic terms what I want to be able to do is increment/decrement a field in a table according to something that happens in a different table. Where do I start?
So for example, a stereo system/cd player can have 10 cds at one particular time, when 2 cds are removed, then 8 slots are available. Then when 1 of the 2 remaining slots are filled then 1 slot remains and so on....so I want some sort of a counter field. Using that field I want to be able to generate a report on what is currently available.
Please Excuse my lame example but can anyone please help?
Thanks

One more for you while I'm trying to remember my SQL skill from a few years ago (last one of the day - promise):
My database looks like:
(Ignore that the ERD is in Access, the database is SQL Server 2005)
How do I calculate sales percentages?
I.E. how do I calculate the percentage that each product has sold as a percentage of the total sales?
What I'm aiming for is each row of products is shown, with its percentage of the whole sales.
AVG is involved this time, isn't it?
The productID is of the int datatype (not that you need to know that field - but never mind) and the quantity is a smallint, before you ask

My site has members. Each member has a certain goal, an amount that they are hoping to raise. Here's my tables:
---------------------
Members
---------------------
ID | Goal
---------------------
---------------------
Donors
---------------------
Amount | MemberID
---------------------
I'm trying to get the percentage of money raised compared to their goal. Basically 100*(SUM(Amount)/Goal). Here's my stored procedure:
CREATE PROCEDURE sproc_GetGoalPercentage
(
@memberid int
)
AS
SELECT(SUM(D.Amount)/M.Goal)*100
FROMMembers AS M INNER JOIN Donors AS D
ON M.ID = D.MemberID
WHEREM.ID = @memberid
GROUP BY M.Goal
RETURN
All it does is return 0.
I'm putting together a manual system that tracks data growth in a certain database. I was going to use sp_spaceused as a part of it, but then realized the datatypes for size are CHAR, not INT or BIGINT. I was going to do counts, averages, etc. on those columns but that wouldn't work against a CHAR field obviously. I could easily write a little something to strip out the KB, but was hoping there was another way to get those figures.
Secondly...has anynoe seen a stored procedure/code/etc. that just calculates the largest/smallest/average row size for a table? I haven't been able to find anything anywhere...
Any insight would be greatly appreciated...
Thanks!

Hi,
Our tables have a reference field which users can enter their own references into.
However, they can choose to have the system calculate the next reference number.
The reference can contain any characters from a-z, A-Z and 0-9.
In our system, reference AAAA is greater than reference ZZZ; the next reference after AAAA is AAAB.
How would I calculate the greatest current reference in the table?
I have a project where I need to populate a table with a Begin and an end date based on another field with in the table. my example is that the other field will have a value of "monthly" I want then a record to be entered on the table with a begin date of November 1 and the en date as November 30th. I want this record to get populated only on business days. my thinking is a stored procedure that runs daily and only creates a record at a time. i am thinking if the user selects weekly the dates populated would be november 1 = begin date and Novemeber 2nd = end date
i want to fill out a current month at a time as if the account closes i will not need the extra cases.
thanks

Hi, I'm in the process of creating a database table and was wondering if it's better to store calculated values or recalculate them each time. So for example, I am creating a table that stores articles and then a table to store the pages to the article. If a new page is added should I update the pages field in the articles table or should I calculate the number of pages for an article when it's queried? Thanks,John
View 3 Replies View RelatedHi I am quite struggling to work out how to calculate profit in stored procedure.
The problem is
I have the table:
share name / transaction date/ is it buy or sell / no of shares bought or sold /total cost
I need to calculate how much profit was made on sold shares
The problem is that I need to always assume that you sell shares which were bought first first.
So if I have in chronological order:
tesco buy 50 £200
tesco buy 40 £100
tesco sell 55 £600
profit is
costtobuy of 55 shares: 50 shares at £200 + 5 shares at (£100/40*5 =)£12.50 = £212.50
profit = £600 - £212.5 = £387.50 (too good to be true)
my plan was (if it is too confusing please ignore it and just read the part above)
1 to work out no of shares sold and total cost of sold shares
so
select sum(no of shares) as nosold ,sharename where transaction = sell and sharename= @sharename return noofshares
select sum(totalsold) as totalcostsold , sharename where transaction = sell and sharename = @sharename return totalsold
now i need to loop through buys to work out cost to buy of number of shares sold:
so i need to loop through a table which would have buy transactions only(share name, nobought, totalcost) and check what was the cost to buy of this number of shares:
@nosold(from above table)
@sharename
output totalcosttobuy = 0
if(nobought = nosold) totalcosttobuy = totalcostobuy + totalcost
retrun
else if (nobought>nosold)totalcosttobuy = totalcostobuy + (totalcost/nobought)*nosold
return
else if( nobought<nosold)totalcosttobuy = totalcostobuy + totalcost
nosold = nosold-nobought (go back to beginning of if)
where sharename = @sharename
group by sharename
Well I need this if statement to loop through the rows in the table how can I do that?
Then I can do profit = totalcosttosell - totalcosttobuy
I have table with three columns: 1) TodaysDate,
2)
DueBackDate,
3) DaysOverdue
The problem I am having is creating a formula in MS SQL, so that when
the 'DueBackDate' column is more than todays date, I want the
'DaysOverdue' column to be incremented accordingly.
I have tried creating an SQL Query something like this:
UPDATE rental
SET DaysOverdue = DaysOverdue + 1
WHERE ({ fn NOW() } > DueBackDate)
But the problem with this that it only increments the 'DaysOverdue'
field by 1. When I want it to basically subtract todays date by
'DueBackDate'.
I have tried to also create a formula within MS SQL but I come up with
errors. I have done something like this in Access which worked. The
Formula looked like this:
IIF(Now()>[DueBackDate],int(Now()-[DueBackDate]),0)
Is there a way to convert this formula so that is would work in MS SQL?
Thanks.
