select SERIALNO, Max(TIME)
from dbo.TASK A
join dbo.Status B
on A.TID=B.TID
where A.ID in ('1111',2222')
and A.TYPE='Pen'
group by B.SERIAL_NO, B.TIME
order by BM.TIME
For this query I may get serial no duplicates but times are unique
For that serial no, I have to find the recent time. But if I use group by, I am getting the wrong no
I work for an organization that repairs serialized devices. Each time a device is repaired it's serial number is recorded in a database table along with the date it was repaired along with other information about the device. There are multiple cases where a unit has been repaired more than once.
I am trying to write a query that will return the serial only once and that record will be the record of the latest repair date. To sum it up,
Return a list of serials where if a serial exists more than once in the table, return only the instance of the serial record(s) with the max(created_dt). The end result will be a list of distinct serial numbers.
Here is my Query. The problem I believe is in my sub-query but I am not sure how to structure it.
Please give me the correct function name, otherwise please ignore in sending reply. I had used all the functions like identity, ident and so on. I need while selecting a querry, i need to generate serial numbers. I dont have identity column in my table. But, i need to generate serial numbers..
In Sybase SQL Any where, we have a function called Number (*) which will in turn generate serial numbers like ex..
Select Number (*) from x
The output will be
Number(*) 1 2 3 4 5 6 and so on..
I need a equivalent function in SQL Server 7.0 in which if i do select on that particular function with a table i should return above values..
I need a query to find max serial number by comparing two different tables. Here is my requirementI am having two tables named Table1 and Table2. Each tables having more than 30,000,000 records.I want a simple query to find Max srno from two tables.For exampleIf Table1 max is 245 where partno=2 and ano=2and Table2 max is 343 where partno=2 and ano=2Then 343 is max serial noIf Table1 max is 435 where partno=2 and ano=2and Table2 max is 34 where partno=2 and ano=2Then 435 is max serial noI used this query but its taking more time select max(v.MaxSrNo) from ((select max(MaxSrNo) as MaxSrNo from Table1 where partno=@partno and ano=@ano)union all (select max(MaxSrNo) from Table2 where partno=@partno and ano=@ano)) as v Pls give me a simple query to find max srno.
I need a new field added 'Field1' which will add SEQUENCE number 1,2,.. based ON GROUP BY MasterID..AND another field TotalCount which will COUNT total masterID (here it will be 2)
I have this table of Marks as shown below. All I need is to find the average Marks at various intervals of S.no. That is I need averages at every 3rd S.No. as shown.
S.No. Marks 1 ------ 5 2 ------ 5 3 ------ 6 1st Average Value here (16/3) 4 ------ 5 5 ------ 6 6 ------ 7 2nd Average Value here (18/3) 7 ------ 7 8 ------ 7 9 ------ 8 3rd Average Value here (22/3) 10 ----- 8 11 ----- 9 12 ----- 8 4th Average Value here (26/3)
So basically I need a new table which will have 4 average values for the table above. Of-course the table can be much bigger and the average values can be at any nth value of S.No.
I have Logs table and want to assign a serial number to the techs using the following query
Select Date, Case_ID, Site, Dept, Tech, Start_Time, ROW_NUMBER () OVER (PARTITION BY Date, Site, Dept, Tech ORDER BY Start_Time) as Row_Num FROM Logs Where Date = Getdate()
I get the following results.
Date Case ID Site DeptTechStart TimeRow_Num 7/28/14 10023 TartvilleMaintcAmy P.7:301 7/28/14 56789 TartvilleMaintcRem W.8:051 7/28/14 23098 TartvilleMaintcAmy P.8:352 7/28/14 70004 TartvilleMaintcAmy P.9:103 7/28/14 12708 TartvilleMaintcMag O.10:001 7/28/14 10004 TartvilleMaintcAmy P.12:304 7/28/14 40056 TartvilleServiceJoe F.7:301 7/28/14 23458 TartvilleServiceJoe F.7:552 7/28/14 69200 TartvilleServiceRus T. 7:301
Please notice the cases in Maintc department. See how Amy P.'s shift is broken by Rem W. and Mag O. But the Row Number does not recognize this, it still says Amy P's case as 2 and 4 the even though Rem's and Mag's cases were in between.
This is what I really wanted.

I tried many combination of columns for Partition by () and Order by () and the best I can get is the result at the top. How should I achieve it.

Get the records with the latest date and time in the destination table TransactionsImport Get the records with the latest date and time in the destination table TransactionsImportDelta table Insert the records from the TransactionsImportDelta table into TransactionsImport that have a greater date & time than the current records in TransactionsImport table.
Problem is date & time are in separate columns:
Table structure:

Is the Date/Time of the latest SQL Server 2005 instance restart stored somewhere in the system catalog? This value is quite relevant when retrieving information on the costliest unused indexes in the instance.
I know of one way of doing this, which is to search the SQL Logs for this info. This solution is very unwieldy - we recycle the logs daily and we only keep the logs of the last 7 days.
I need to find the missing months in a table for the earliest and latest start dates per ID_No.  As an example:

I have a table name farmer data and it has attributes like farmer name, father name, pesticides used, town etc (these attributes would be required for query). also the data type of columns is var char.
I have to write a query to calculate the average no of farmers in each town.
How can I write this query? I have tried this query but its not giving me the count of all the farmers in each town. its not giving me the count of distinct farmers
select town, count (*) from farmer_data group by town

I have a table with PO#,Days_to_travel, and Days_warehouse fields. I take the distinct Days_in_warehouse values in the table and insert them into a temp table. I want a script that will insert all of the values in the Days_in_warehouse field from the temp table into the Days_in_warehouse_batch row in table 1 by PO# duplicating the PO records until all of the POs have a record per distinct value.
Example:
Temp table: (Contains only one field with all distinct values in table 1) Days_in_warehouse 20 30 40

In my database times are stored as integers. Therefore if someone arrives a 1am the value is 60, 2am 120 etc. Is there a way to convert these integer values to 1:00, 2:00. I've tried converting to a decimal so if somene arrives at 1:30 it returns 1.5, but I still only get the integer value...

As the Microsoft Time Series algorithm implementation is based upon the Autoregressive Tree approach described in:
C. Meek, D. M. Chickering, D. Heckerman. Autoregressive Tree Models for Time-Series Analysis. In Proc. 2nd Intl. SIAM Conf. on Data Mining, 2002 (SDM-02). SIAM, pp. 229 €“ 244. http://www.siam.org/meetings/sdm02/proceedings/sdm02-14.pdf.
The model estimated is refererred to as an instance of "... autoregressive tree models of length p, denoted ART(p). An ART(p) model is an ART model in which each leaf node of the decision tree contains an AR(p) model, and the split variables for the decision tree are chosen from among the previous p variables in the time series..." (see the last paragraph of p. 2 of the paper).
What is the value of "p" used in the Microsoft Time Series implementation -- specifically, how many previous time series variables are used in estimating the model? It doesn't appear that this value can be specified in the algorithm parameters -- is that correct?
I have to build a database model, create tables and use triggers or/and procedures on it. It's about a library. Books are borrowed by students. They can make a reservation of a book.
I built the database model so far. My problem is how to represent following tasks:
- Students can borrow a maximum of 5 books at the same time. - bookings/book reservations should be later processed in the order they occurred. That is, who first flagged the book also gets the book/books first
I have following entities:
- Book - Book exemplar - Borrowed by (a table between the entities Book exemplar and Student) - Reserved for (a table between the entities Book exemplar and Student) - Student
How would you represent the tasks I mentioned above in terms of triggers or procedures?...
