How to find the equal and opposite rows in a table.
E.g.:
book position
A 500
B -500
C -500
The output should return the rows having equal and opposite positions.
O/P:
A 500
B -500
I have tried self join on a table but in vain.Do we need to cursors for these row level handling?
Hi,
When expoting data from excel to sql server table, using SSIS package, after exporting is done, how would i check source rows are equal to destination rows. If not to throw an error message.
How can we handle transactions in SSIS
1. when some error/something happens during export and the # of rows are not exported fully to destination, how to rollback the transaction in SSIS.
Any sort of help would be highly appreciated.
Thanks,

I have a table containing the following data:
LinkingIDID1 ID2
166202180659253178
166202253178180659
166334180380253179
166334253179180380
166342180380180659
166342180659180380
166582253179258643
166582258643253179
264052258642258643
264052258643258642
264502258643258663
264502258643259562
Within the LinkingID, there are duplicates in ID1 and ID2 but just in opposite columns. I have been trying to figure out a way to remove these set based. It doesn't matter which duplicate is removed. Essentially these are just endpoints and I don't care which side they are on. The solution must recognize the duplicates and not just remove based on every 2nd row.
i have a table like below
create table staff_attendance
(

2 2014-06-30 00:00:00.0ST10122

I Need to find the duplicate rows like same entries which is having more than 1 rows.... how do i find?
I have two table in two different database. I have to found count for both table and put into other table.

I am trying to find books which have the same title and publisher name as at least two other books and need to also show the book ref (ISBN number). I have the below script so far:
SELECT isbn, title, publishername
FROM book
WHERE title in (SELECT title
FROM book
GROUP BY title
HAVING count(title)>2 or count(publishername)>2)
order by title;
This is a snap shot of the output:
ISBN Title Publishername
0-1311804-3-6 C Prentice Hall
* 0-0788132-1-2 C OSBORNE MCGRAW-HILL
* 0-0788153-8-X C OSBORNE MCGRAW-HILL
* 0-9435183-3-4 C Database Development MIS
* 1-5582806-2-6 C Database Development MIS
[Code] ....
What I should be seeing is only the ones I have put an * next to. What am I missing from the scrip?
Select statement joining file1 to file2. File 1 may have 0, 1, or many corresponding rows in file2. I need to count the corresponding rows in table2. Table2 also has a Boolean column and I need to count the number of rows where it is true. So I need to count the total number of matching rows and the count of those that are set to true. This is an example of what I have so far. I had to add each column being selected into a Group by to make it work, but I do not know why. Is there some other way this should be set up.
SELECT c.CarId, c.CarName, c.CarColor, COUNT(t.TrailerId) as trailerCount, (add count of boolian, say t.TrailerFull is true)
FROM Car c
LEFT JOIN Trailer t on t.CarId = c.CarId
GROUP BY c.CarId, c.CarName, c.CarColor
I have the below table :
IDName Date_StartDate_End Time_StartTime_End
9xxxxx@gmail.com 13/06/2015NULL 23:00.0 NULL
10xxxxx@gmail.com NULL 14/06/2015 NULL 00:00.0
11xxxxx@gmail.com 15/06/2015NULL 00:00.0 NULL
12xxxxx@gmail.com NULL 15/06/2015 NULL 00:00.0
13xxxxx@gmail.com 14/06/2015NULL 00:00.0 NULL
14xxxxx@gmail.com NULL 14/06/2015 NULL 00:00.0
Then i need to replace second row with value with first row with null and so on :
IDName Date_StartDate_End Time_StartTime_End
9xxxxx@gmail.com 13/06/201514/06/2015 23:00.0 00:00.0
10xxxxx@gmail.com NULL NULL NULL NULL
11xxxxx@gmail.com 15/06/201515/06/2015 00:00.0 00:00.0
12xxxxx@gmail.com NULL NULL NULL NULL
13xxxxx@gmail.com 14/06/201514/06/2015 00:00.0 00:00.0
14xxxxx@gmail.com NULL NULL NULL NULL

I am doing a performance testing for In-memory option is sql server 2014. As a part I want to insert 500 million rows of records into a in-memory enabled test table I have created.

I have a CTE query against a table with 32K rows that runs fine in 2008R2. I am running it in 2014 Std Ed. against the same data and it runs very slowly. Looking at the execution plan I think I see what's contributing to the slowness.
Note that the "actual number of rows" is some 351M...how is this possible?
the query:
declare @amts table (claim int,allowed decimal(12,2),copay decimal(12,2),deductible decimal(12,2),coins decimal(12,2));
;with unpaid (claimID) as (select claimID from claim where amt+copay + disct+mm + ded=0)
insert @amts
select lineID, sum(rc), sum(copay), sum(deduct),
case when sum(mm)>0 and (sum(mm)<sum(mmamt)) then sum(mm) else 0 end
from claimln
where status is null
and lineID not in (select claimID from unpaid)
group by lineID
it's like there's some massively recursive process going on?
I have a table with following rows.

Month BNQ FNB RS
JUL 1054839 89032 1067299
JUN 2000000 1000000 3000000
I tried with the following and result is coming for one month i.e. JUL but not with the second Month i.e Jun
SELECT 'Jul1' AS MON, [BNQ], [FNB], [RS]
FROM
(SELECT REVENUECODE, SUM(ROUND(((Jul/31)*30),0)) AS JUL

Can't seem to make this SQL query work!
Given one table, Table1, with columns Key1 (int), Key2 (int), and Type (varchar)...
I would like to get the rows where Type is equal to 'TypeA' and Key2 is Null that do NOT have a corresponding row in the table where Type is equal to 'TypeB' and Key2 is equal to Key1 from another row
So, given the data
**KEY1** **Key2** **Type**
1 NULL TypeA
2 5 TypeA
3 1 TypeB
4 NULL TypeA
5 NULL TypeB
I would like to return only the row where Key1 = 4 because that row meets the criteria of Type='TypeA'/Key2=NULL and does not have a corresponding row with Type='TypeB'/Key1=Key2 from another row.
I have tried this and it doesn't work...
SELECT t1.Key1, t1.Key2, t1.Type
FROM Table1 t1
WHERE t1.Key2 IS NULL
AND t1.Type LIKE 'TypeA'
AND t1.Key1 NOT IN
(SELECT Key1
FROM Table1 t2
WHERE t1.Key1 = t2.Key2
AND t1.Key1 <> t2.Key1
AND t2.Type LIKE 'TypeB')
It is possible to find table size and in that table each row size.

Hi Frinds,
How can i find out the no of rows in each table. if the no of table are more than thousands(i.e. 1000+,2000+ etc..) are there. Certainly 'select count(0) from <table>' is not the good idea. Egarly awaiting for the solution.

Consider a table with the following structure:
RecordID (PK - int) - RecordDate (DateTime)
I need to find all records that fall within a 7 day period slot based on the first RecordDate of a specific slot.
Example, consider the following records:
RecordID - RecordDate

2 - 2015-04-03 15:00
3 - 2015-04-03 16:05

2

7
8
So basically I'd like to leave record 3 and 4 out because they fall within 24 hours of record 2 and I'd like to leave record 6 out because it falls within 24 hours of record 5.I'd tried working with a CTE and set a dateadd(d, 1, recorddate), join it on itself and use a between From / To filter on the join but that didn't work. I don't think NTILE will work with this?
