SQL Server 2012 :: Get Only Records Which Row-number Is 0 Or 1 In Module 20?
Mar 5, 2015
With this query i get only the records i need, but i would like to output in this way
1 - 20
21 - 30
31 - 40
of course in the real environment the ID are not consecutive, this is just one example of data.
declare @temp table (ID int)
declare @i int = 1
while(@i<1000) begin
insert into @temp values (@i)
set @i=@i+1
end
select ID from (
select ID, row_number() over (order by ID)
as rn
from @temp
) q where (rn % 20=0) OR (rn % 20=1)
A New Monthly data is being loaded, checked and finally approved after 6 or 7 iteration before approval.Because of this iteration the monthly data set is being added then deleted then added then deleted few times.Because the table is big this process takes time, any thoughts on how to make the delete insert process faster.Keep in mind I cannot do much because it is a production table and is being access by other users to do other analysis.
Delete is done based on trx_date which is a year/month combo, like 201508.
The table has monthly sales by customer aggregated.
The table structure is:
CREATE TABLE [dbo].[Sales]( [batch_key] [int] NOT NULL, [Company_key] [int] NOT NULL, [customer_key] [char](22) NOT NULL, [Trx_Date] [int] NOT NULL, [account] [nvarchar](35) NOT NULL,
Is it possible to change the EXECUTE AS principal on a module (such as a stored procedure or function) without having to redefine the entire module in an ALTER statement? I didn't find anything in BOL about it in the ALTER PROCEDURE or ALTER FUNCTION articles. If there is a system sproc that does it, I couldn't find it. Changing system tables is not an option (assuming that is an option) for me.
writing the query for the following, I need to collapse the continuity. If the termdate for an ID is one day less than the effdate of the next id (for the same ID) i need to collapse the records. See below example .....how should i write the query which will give me the desired output. i.e., get min(effdate) and max(termdate) if termdate is one day less than the effdate of next record.
I have a table of Customers & their data in about 20 Columns.
I have another table that has potential Customers with 3 Columns.
I want to append the records from Table 2 onto Table 1 to the Columns with the same names.
I've thought of using UNION ALL or Select Insert but I'm mainly stuck on the most efficient way to do this.
There is also no related field that can be used to join the data as these Customers in table 2 have no Customer ID yet as they're only potential Customers.
Can I just append the 3 columns from Table 2 to the same 3 columns in table 1?
I have a large table of customers. I would like to add a column that contains an integer, unique to that customer. The trick is that this file contains many duplicate customers, so I want the duplicates to all have the same number between them.the numbers dont have to be sequential or anything, just like customers having the same one.
Hi We are using the SQL Server 2005 Full Text Service. The data is not huge, but the kind of data is that each record is small and there are a large number of records. There are 35 million records now with 11 GB of data and about 1.6 GB of FT catalog on the table. This is expected to grow to at least 10 times the size of this data. The issue is with FTS taking a long time to return results when the number of hits (rows) getting returned from FTS is large for some searches, it takes a very long time. With the same data & catalog, those full text queries for less common words return timely. The nature of the problem doesnt allow us to only have top results. We need all the results. So it’s not about the size of data but the number of results getting returned from FT. (As the catalog is inverted). The machine is dual processor with 4 GB RAM.
I am considering splitting the table and hence the catalog and using multiple servers to do full text searches in smaller catalogs. Is there any other way this issue can be solved ?
If splitting is the only way, can you give me an idea as to what is a statistical/standard limit to the number of search results/cataog size as which FTS gives good results
I have duplicate records in table.I need to count duplicate records based upon Account number and count will be stored in a variable.i need to check whether count > 0 or not in stored procedure.I have used below query.It is not working.
SELECT @_Stat_Count= count(*),L1.AcctNo,L1.ReceivedFileID from Legacy L1,Legacy L2,ReceivedFiles where L1.ReceivedFileID = ReceivedFiles.ReceivedFileID and L1.AcctNo=L2.AcctNo group by L1.AcctNo,L1.ReceivedFileID having Count(*)> 0 IF (@_Stat_Count >0) BEGIN SELECT @Status = status_cd from status-table where status_id = 10 END
I have a challenge and I'm not sure the best route to go. Consider the following dataset.
I have a table of sales. The table has fields for customer number and date of sale. There are 1 - n records for a customer. What I want is a record per customer that has the customer number and the average number of months between purchases. For example, Customer 12345 has made 5 purchases.
I have one stored proc that uses the Row_number over partition that looks like this:
Select TargetID, Academic_Year_id, Course_Mode, UK_Enrol, Int_Enrol, Notes, Revision_Number from (SELECT ROW_NUMBER() OVER (partition by [Academic_Year_id] order by [Revision_Number] DESC) as [RevNum],TargetID, Academic_Year_id, Course_Mode, Target_Year, UK_Enrol, Int_Enrol, Notes, Revision_Number FROM tbl_targets where course_mode=@course_mode) RV where (RV.RevNum=1)
Now the next store proc needs to use the above but i need to add the Academic_year from the tbl_acyear_lookup table also add filter the target_year ='year 1'
I have come to know from the SQL Server documentation that the Hardware Security Modules (HSM) can be used for Cryptographic Key storage within SQL Server to increase the level of protection of data at rest. We provide a HSM Solution which protects cryptographic keys and performs cryptographic operations onboard. The aforesaid fact about SQL Server and HSMs motivates us to test our HSM product with the SQL Server. Our HSM solution provides SDK for applications/servers to communicate with the HSM hardware. The SDK basically consists of two libraries:
-MS CAPI Interface (CSP Library)
-PKCS#11 Interface (cryptoki Library)
I have found this forum best for such kind of discussion. So could you guys on the list let me know:
- How the CSP or PKCS#11 library can be integrated with the SQL Server for HSM box to protect the cryptographic keys?
- Would I need to write a new Interface/Wrapper for this integration, If yes please help?
I have problem when installing SQL 2005 Enterprise to my Windows 2003 R2 cluster. I install the SQL instance on the first node in my cluster, it analyses the cluster and comes up with no errors or warnings, i answer all the installation questions and proceed with the installation. When installing the SQL engine I see the status changing as the instance is started and then stopped again etc, finally the status changes to "removing backup files" when it get an error that reports:
"The setup has encountered an unexpected error while Completing Commit. The error is: The specified module could not be found."
Unfortunately there isnt any more information to go on. Any help would be appreciated.
How to create a row number for a consecutive action. Example: I have a listing of people who have either completed a goal or not. I need to count by person the number of consecutively missed goals.
My sql table is this: PersonId, GoalDate, GoalStatus (holds completed or missed)
My first thought was to use the rownumber function however that doesn’t work because someone could complete a goal, miss a goal, then complete one and when they complete a goal after a missed goal the count has to start over.
In a t-sql 2012 select statement, I have a query that looks like the following:
SELECT CAST(ROUND(SUM([ABSCNT]), 1) AS NUMERIC(24,1)) from table1. The field called [ABSCNT] is declared as a double. I would like to know how to return a number like 009.99 from the query. I would basically like to have the following:
1. 2 leading zeroes (basically I want 3 numbers displayed before the decimal point)
2. the number before the decimal point to always display even if the value is 0, and

add a number to the end of an ID to create a series.For example, I have an EventID that may have many sub events. If the EventID is 31206, and I want to have subEvents, I would like have the following sequence. In this case, lets say I have 4 sub Events so I want to check the EventID and then produce:
312061 312062 312063 312064
How can I check what the EventID is, then concatenate a sequence number by the EventID?
For example in a table with this fields "field1, L1,L3,L100" field2 the count is 3
it would be better to match a number into the like but i thinks it cannot be done in the like so i've to add another condition to ensure all the text after L is a number.
is this the best way to do it?
Select count(*) from Information_Schema.Columns Where Table_Name = @Table AND column_name like 'L%' and ISNUMERIC(SUBSTRING(column_name,2, len(column_name)-1))=1
I am developing a form for a mortgage company. There can be any number of borrowers on a given loan, and the business has asked that this form return only 2 borrowers at a time for a loan. For example, if there are 3 borrowers for a loan, they want the first copy of the form to print the first 2 borrowers and then another copy of the form to print the 3rd. No matter how many copies are printed, they want the borrower information to be labeled as 'Borrower1' xyz and 'Borrower2' xyz. Also, there will be a LOT more fields returned on the real form, so the sample information below is very simplified test data.
I don't want that 2nd record to return. This result is what makes me think of gaps and islands, but I don't know if the 2nd record is really an island since it's (1) not stored this way...it's returning this way because of the query and (2) it's not sequential data..I tried restricting this by putting this into a CTE and then returning only the odd numbered records like I have below. This runs pretty quickly when dealing with one loan. But...I am concerned that the CTE will be slow when we run batches of loans.
Attempt with CTE: --With CTE ;WITH cte AS (SELECT Borrower1 = BorrowerName , Borrower2 = LEAD(BorrowerName) OVER(ORDER BY BorrowerOrder) , RowNumber = ROW_NUMBER() OVER(ORDER BY BorrowerOrder)
[code]...
Is there a better, cleaner way to do this? Or is the CTE the best way to go?
I have to create a table like this across a bunch of servers. I'm thinking that I'm overlooking something with needing two additional CTEs, but maybe not. I have it at 17 seconds, which isn't much faster than a while loop solution that's currently in place.
