SQL Server 2012 :: Identify Sets Of Rows
Jul 15, 2015
I have the following sets of records:
ColA ColB
----- -----
21 A
22 A
23 A
24 B
25 B
26 D
What I want is to be able to identify a set sequence (1,2,3) based upon ColB such that I'd get the following result:
ColA ColB ColC
----- ----- -----
21 A 1
22 A 1
23 A 1
24 B 2
25 B 2
26 D 3
I know that I should be able to get it using ROW_NUMBER() OVER (PARTITION BY ColB ORDER BY ColA), but instead of getting the sequence (1,1,1,2,2,3) I get (1,2,3,1,2,1). Using DENSE_RANK gave me the same results.

I am struggling to come up with a set-based solution for this problem (i.e. that doesn't involve loops/cursors) ..A table contains items (identified by an ItemCode) and the set they belong to (identified by a SetId). Here is some sample data:
SetIdItemCode
1A
1B
24
28
26
310
312
410
[code]....
You can see that there are some sets that have the same members:
- 1 and 10
- 2 and 11
- 7, 8 & 9
What I want to do is identify the sets that have the same members, by giving them the same ID in another column called UniqueSetId.

I want to identify rows that go negative but only for 2 cents or more as well as identify rows that 2 or more.
I have this expression that does not work how I want it to work:
CASE
WHEN (SUM(FavUnfavCostChange) < (2/100) THEN 'Less'
WHEN SUM(FavUnfavCostChange) > (2/100) THEN 'More'
ELSE NULL
END AS 'Flag'
But I get:
0.00000815000000000000More -- this is not more than 2 cents, is just a positive number
-0.00094700000000000000Less -- this is not less than 2 cents, is just negative number
-0.00222000000000000000Less -- this is not less than 2 cents, is just negative number
-0.00012250000000000000Less -- this is not less than 2 cents, is just negative number
0.00000000000000000000NULL -- this is zero so null is fine
0.01188576000000000000More -- this is not more than 2 cents, is just a positive number

I am in process to develop TSql code to identify change in data.
I read about Binary_checksum and hashbyte. Some people say hashbyte is better than binay_checksum as chances of collision are less.
But if we may consider following, chances exist in hashbyte too. My question is what is the best way to compare data to identify change (I can't configure CDC) ?
select HASHBYTES('SHA','121'+'34'), HASHBYTES('SHA','12'+'134'),BINARY_CHECKSUM('121','34'),BINARY_CHECKSUM('12','134');

A DB2 store procedure returns two data sets, when executed from SSMS, using linked server. Do we have any simple way to save the two data sets in two different tables ?

so async cursor population is supposed to create the cursor and return the cursor id quickly, while the server works on async populating the results. For a keyset-driven cursor, SQL Server stores the key sets in tempdb, which it then uses to fetch data for cursor results. Anyway, this works fine for smaller tables, but I'm finding for large result sets, the async cursor population is very slow and indeed seems to approximate synchronous time. The wait stat I get while it is running (supposedly asynchronously) is TRANSACTION_MUTEX.
Example:
--enable async cursor
exec dbo.sp_configure 'cursor threshold', 0; reconfigure;
declare @cursor int, @stmt nvarchar(max), @scrollopt int, @ccopt int, @rowcount int;
--example of giant result set
set @stmt = 'select * from sys.all_objects o1, sys.all_objects o1';
[code]...
Note that using the SQL "select * from sys.all_objects o1" is much faster than "select * from sys.all_objects o1, sys.all_objects o2". However, if cursor population is async, I'd expect the time to return a cursor id to be similar between the two.

Hi folks. Hope all the gurus including Brett,Pat Phalen, RdjBarov, r937 are fine. ;)
been so long to ask stupid question. Here's the question and i really need help on this.
i have data that tracks patterns of bus stops from one point to another.
like point a, to point b, point b to point c forms one pattern.
point a to point c , point c to point b should be a different pattern.
create table #journeypatterns (patternid int ,points varchar(100))
go
insert #journeypatterns
select 1 ,'a' union all select 1 ,'b' union all select 1,'c'
union all select 2,'a' union all select 2,'c' union all select 2,'b'
union all select 3 ,'a' union all select 3 ,'b' union all select 3,'c'
select * from #journeypatterns
patternid points
1 a
1 b
1 c
2 a
2 c
2 b
3 a
3 b
3 c
what i want is to get unique pattern value of sequence of points by grouping on patternid. if the sequence of points change, i need a unique value against that pattern.
like for patternid 1, sequence of points a,bc for example should be abc.
for patternid 2, sequence of points a,c,b for example should be acb.
again patternid 3, sequence of points a,bc for example should be abc.
i tried CHECKSUM_AGG which brutally failed in production because the checksum values for each single point when summed produce SAME result for different patterns.
select checksum_agg(binary_checksum(points)) ,patternid
from #journeypatterns
group by patternid
961
962
963
here patternid 2 should be different because sequence is acb. i know checksum is not the right approach for what i need.
I NEED A GENERIC FUNCTION, that marks the pattern differences, my ultimate goal was to create a procedure, whom a patternid should be passed, and it would result the NEXT patternid in the table which has the SAME ORDER OF point sequences.
now folks, i can do this holding all data into a temp table and write a cursor to traverse through each patternid and concatenate the sequence of points.
BUT, using this approach is the ugliest, as it has slow down the process badly and boss is not happy with the performance. the table holds a lot of data.
I NEED a query rather than a cursor on the fly to resolve this.
Here's the query i am using to get the current sequence of a pattern and then i have to search all sequences similarly against it.
declare @patternid int
set @patternid =1
declare @sequence [varchar] (100)
declare @id varchar(10)
declare cr_sequence cursor fast_forward for select points from #journeypatterns where patternid=@patternid
open cr_sequence
fetch next from cr_sequence into @id
while @@fetch_status = 0
begin
select @sequence = isnull(@sequence,'')+@id
fetch next from cr_sequence into @id
end
print @sequence -- next i have code to find the similar sequence for another patternid.... which is not mentioned here but is similar

Hello,
I want two different set of rows in a single output. For example - the query gets records from the same tables, but first condition is a date range of 60 days and value = '1'
then the second condition is a date range of 180 days and value = '2'
Is it possible?

Given an ID (column B), I need to find which IDs have identical data.That is, given '200', I want the desired result to be:100The idea is that the system sees that id=200 has 5 records with theindicated data in cols C and D.It should then find any other ids with the exact same data for thosecolumns.Note, in this case, both 200 and 100 have (30:1, 30:2, 30:3, 40:4,40:5) so they match. 300 and 400 should NOT be returned.Any bright ideas out there? Thanks!DECLARE @a TABLE(A int, B int, C int, D int)DECLARE @b TABLE(A int, B int, C int, D int)INSERT INTO @a (A, B, C, D) VALUES (1, 100, 30, 1)INSERT INTO @a (A, B, C, D) VALUES (2, 100, 30, 2)INSERT INTO @a (A, B, C, D) VALUES (3, 100, 30, 3)INSERT INTO @a (A, B, C, D) VALUES (4, 100, 40, 4)INSERT INTO @a (A, B, C, D) VALUES (5, 100, 40, 5)INSERT INTO @a (A, B, C, D) VALUES (6, 200, 30, 1)INSERT INTO @a (A, B, C, D) VALUES (7, 200, 30, 2)INSERT INTO @a (A, B, C, D) VALUES (8, 200, 30, 3)INSERT INTO @a (A, B, C, D) VALUES (9, 200, 40, 4)INSERT INTO @a (A, B, C, D) VALUES (10, 200, 40, 5)INSERT INTO @a (A, B, C, D) VALUES (11, 300, 30, 1)INSERT INTO @a (A, B, C, D) VALUES (12, 300, 30, 2)INSERT INTO @a (A, B, C, D) VALUES (13, 300, 40, 3)INSERT INTO @a (A, B, C, D) VALUES (14, 400, 40, 4)INSERT INTO @a (A, B, C, D) VALUES (15, 400, 40, 5)SELECT * FROM @a

I have a table with multiple rows per staff person. Each of these rows has staff_id, start_date, and end_date. Per staff, if any start_date comes between the start_date and end_date of a different row, or if any end_date comes between the start_date and end_date of a different row, then I have to flag these records as being identical.
How can I do this? I have tried doing a Cross Apply because I thought that would do Cartesian product (comparing every row), and I've also tried temp tables. But I haven't gotten either of these to work. Here is some dummy data:
if exists (select * from tempdb.dbo.sysobjects o where o.xtype in ('U') and o.id = object_id(N'tempdb..#staff_records')
) DROP TABLE #staff_records;
create table #staff_records
(
staff_id varchar(max),

In MySQL we use "SELECT (....) LIMIT 0, 10" to only return the first 0 to 10 records. Alternatively we could do "LIMIT 10, 20" to return the 10th to 20th records.
What's the equivilent of this in SQL Server?
Thanks

I need to get 3 rows per set based on a date given (must be this date) but I want the rows to be based on this date as...
1 ( row where the date from the date column is the next date after given date )
0 ( row where the date is the closest date prior to the date given )
-1 ( prior to the date at 0 )
And add a column with the relative number.
** The dates for the same name and item will never repeat.
For example, a set of rows...
Row ID, Name, Item, Number, Date
1 Andy, Item1, 12030, 2014-06-30
2 Andy, Item1, 62030, 2014-03-31
3 Andy, Item1, 30300, 2013-12-31
4 Andy, Item1, 40030, 2013-10-31
5 Andy, Item1, 50030, 2013-08-30
6 John, Item2, 50240, 2014-04-30
7 John, Item2, 41400, 2014-03-31
8 John, Item2, 40509, 2014-01-31
9 Andy, Item2, 24004, 2014-03-31
10 Andy, Item2, 20144, 2013-12-31
11 Andy, Item2, 20450, 2013-09-30
12 Andy, Item2, 25515, 2013-06-30
If I have 2014-03-15 as the date and search for 'Andy', I expect...
Row ID, Item, Date, Relative Date
2, Item1, 2014-03-31, 1
3, Item1, 2013-12-31, 0
4, Item1, 2013-10-31, -1
9, Item2, 2014-03-31, 1
10, Item2, 2013-12-31, 0
11, Item2, 2013-09-30, -1
This is what I'm using which I have no issues switching if necessary...
DATEDIFF( quarter, 2014-03-31, date )
date BETWEEN DATEADD( quarter, -1, '20140315' ) AND
DATEADD( day, 1 ( DATEADD ( quarter, 2, '20140315' ) )
which returns...
Row ID, Item, Date, Relative Date
2, Item1, 2014-06-30, 1
3, Item1, 2014-03-31, 0
4, Item1, 2013-12-31, -1
9, Item2, 2014-03-31, 0
10, Item2, 2013-12-31, -1
Not sure if date math is the best option here. Perhaps using row_number() in some way?
I'm trying to avoid having to process the entire table programmatically given the size of the data set.

I have an odd one. I have a SQL job that doesn't have a schedule and is being run each morning. It is a legacy system and I am trying to document the data flow process and I am having a hard time tracking down where/what is starting the job. I see which user executed the job:
SELECT message FROM sysjobhistory WHERE job_id = 'jobid' AND run_date > 'yesterday'
Which is useful, but I want to know what is starting the job.

2) STUD_COURSE_PERF: TABLE: for course performance.
I've got to group the result set on STUD_ID,ANNUAL_YEAR, Course_ID and the other essential
3) STUD_SUB_PREF: TABLE: Evaluating Subjects difficulty
I've got to group the result on STUD_ID,ANNUAL_YEAR, Course_ID, SUBJECTS_OPTED and other essentail.

I run the following statement and it will not update beyond 7 million plus rows and I have about 38 million to complete. I keep checking updated row counts and after 1/2 day it's still the same so I know something is wrong because it was rolling through no problem when I initiated it. I need to complete ASAP so it's adding to my frustration. The 'Acct_Num_CH' field is an encrypted field (fyi).
SET rowcount 10000
UPDATE [dbo].[CC_Info_T]
SET [Acct_Num_CH] = 'ayIWt6C8sgimC6t61EJ9d8BB3+bfIZ8v'

I have a dataset that contains an EmployeeID, StartDate, EndDate, and Location. Each record tells me at which location and employee was during a payroll period (fortnightly). So the data looks like:
EMP_KEYSTART_DTEND_DTLOCATION
120130117201301318103
120130117201301318103

120130214201302283354
220130214201302281234
Employees can be at multiple locations during the two weeks. They can work at one location, stop working there, start working somewhere else, and then maybe go back to their old location. There are duplicate records here as each employee can be at the same location multiple times during the two week period. What I need to capture is the actual start and end date of an employee at each location for each 'assignment'. An assignment is defined as a continual period of employment at a location with gaps of no less than 4 days - if there is a gap of more than four days then that is classed as a new assignment.

12222-222-2222
21111-111-1111

1111-111-1111222-222-2222
2111-111-1111NULL
3NULL222-222-2222
Basically if the type code is 1 one then move the data to column phone1, if the type is 2 then move it to column phone2.
This would be fairly simple if we always have type codes 1 and 2. But sometimes we can have type 1 and not type 2, or we could have type 2 and not type1.
Right now we only have 2 type codes. But, in the future we could be adding a 3rd type. So that would add a 3rd column (phone3).
Below is my code that I have written. I move the data into a temp table then list it. I am thinking of making this a view to my table. It works just fine. My question is, is there a better and more efficient way of doing this?
CREATE TABLE #Contacts (
id INT PRIMARY KEY,
phone1 VARCHAR(15),
phone2 VARCHAR(15)
)
-- Insert the records for type 1
INSERT INTO #Contacts
SELECT id,
phone_num,
NULL
FROM test1
WHERE type_code = '1'
-- Insert the records for type 2, if the id does not exist for type 1
INSERT INTO #Contacts
SELECT id,
NULL,
phone_num
FROM test1
WHERE NOT EXISTS (
SELECT 1
FROM #Contacts
WHERE #Contacts.id = test1.id
)
AND test1.type_code = '2'
-- if the id has both type 1 and 2, update the phone2 column with the data from type 2
UPDATE #Contacts
SET phone2 = test1.phone_num
FROM #contacts
JOIN test1 ON test1.id = #Contacts.id
WHERE type_code = '2'
SELECT id, phone1, phone2
FROM #Contacts
DROP TABLE #Contacts

In a t-sql 2012 sql script, I have the following script, that only works for a few records since the value of TST.dbo.LockCombination.seq only contains the value or 1 in most cases. Basically for every join listed below, there should be 5 records where each record has a distinct seq value of 1, 2, 3, 4, and 5. Thus my goal is to determine how to add the missing rows to the TST.dbo.LockCombination where there are no rows for seq values of between 2 to 5. I would like to know how to insert the missing rows and then do the following update statement. Thus can you show me the sql on how to add the rows for at least one of the missing sequence numbers?
UDATE LKC
SET LKC.combo = lockCombo2
FROM [LockerPopulation] A
JOIN TST.dbo.School SCH ON A.schoolnumber = SCH.type
JOIN TST.dbo.Locker LKR ON SCH.schoolID = LKR.schoolID AND A.lockerNumber = LKR.number
JOIN TST.dbo.Lock LK ON LKR.lockID = LK.lockID
JOIN TST.dbo.LockCombination LKC ON LK.lockID = LKC.lockID
WHERE LKC.seq = 2
A normal select statement looks like the following:
select * from TST.dbo.Locker LKR
JOIN TST.dbo.Lock LK ON LKR.lockID = LK.lockID
JOIN TST.dbo.LockCombination LKC ON LK.lockID = LKC.lockID
where LKR.number in (000,001,1237)
In case you need the ddl statements for the tables affected here are the ddl statements:
CREATE TABLE [dbo].[Locker](
[lockerID] [int] IDENTITY(1,1) NOT FOR REPLICATION NOT NULL,
[schoolID] [int] NOT NULL,
[number] [varchar](10) NOT NULL,
[serialNumber] [varchar](20) NULL,
[type] [varchar](3) NULL,
[locationID] [int] NULL,

Is there a efficient way to compare two different columns of 2 different rows in a data set as shown below.
For eg: I would like to DateDiff between Date2 of RowID 1 and Date1 of RowID 2 of IDNo 123. After this comparision , if datediff between two dates are <=14 then i want to update 1 else 0 in IsDateDiffLess14 of RowID1 . In below example its 0 because datediff of two dates >=14. So, want to compare the Date2 and Date1 in this sequence for the same IDNo. For RowID 6 there is only 1 row and no other row to compare, in this case IsDateDiffLess14 should be updated with 0.
RowID IDNo Date1 Date2 IsDateDiffLess14
1 123 04/10/2013 04/12/2013 0
2 123 05/10/2013 05/11/2013 1
3 123 05/21/2013 05/25/2013 0
4 112 01/10/2013 01/14/2013 1
5 112 01/27/2013 01/28/2013 0
6 120 03/10/2013 03/12/2013 0

I have a query that produces unique rows. However, some of the unique rows have the column called testname that has the same test listed more than once. All I want to do is drop the older testname and keep the testdate column.
Select
Distinct
TestID,
TestDate,
TestName
From third.test
I want to keep testdate in the query....guessing I need to put in to a temp table then drop the oldest one somehow by doing a subquery using Select Max....

This is a followup to a previous question to a previous but in reverse of Find rows where value in column not found in another row
Given one table, Table1, with columns Key1 (int), Key2 (int), and Type (varchar)...
I would like to exclude any two rows where Type is equal to 'TypeA' and Key2 is Null that 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
6 26 TypeC
7 NULL TypeD
8 NULL TypeD
I would like to return all the rows except where Key=1 and Key=3 because those rows together meet the criteria of Type='TypeA'/Key2=NULL and does have a corresponding row with Type='TypeB'/Key1=Key2.

I have a table (represented by #Events) that holds modifications made to another table. I do have some control over the table structure and indexing. I want to pull all of the change records that were made between two dates.
The tricky part is to include the previous version of each record, which will usually be found prior to the start date in question.
The code that I have provided below works. So you can use it to easily see what should be returned. But it's very slow in production.
Any better method to pull this data together?
-- Production version of this table has 4.5 million rows (roughly 1,000 rows per day)
-- Primary key is on L4Ident (clustered)
-- nonclustered index on ProcessDate, LinkRL4
DROP TABLE dbo.#Events;
DROP TABLE dbo.#Results;
CREATE TABLE dbo.#Events (
L4Ident int IDENTITY(1,1) NOT NULL,
[Code] ....

I am finding it difficult to find an example that allows for insertion of additional rows into a table, without dropping the table I'm inserting into. Or inserting specific values. Like this example..
[URL] ....
I have 6 table I am formatting the data to conform to the final table as I'm inserting it into, but none of these examples gives me the example needed. I am using SQL 2012.
<code>
SELECT
CONVERT(VARCHAR(50),[FName]) + ' ' + CONVERT(VARCHAR(50),[LName]) AS [CustName]
,CAST('ALARMCOM' as nvarchar(8)) as VendorName
,CONVERT(VARCHAR(25),[CUSTOMER_CS_ACCOUNT_NUMBER]) AS [Cust_ID]
,CONVERT(VARCHAR(40),[Charge_Description])as [ChargeType]
,CASE
[Code] ....
