T-SQL (SS2K8) :: Update Records Separated By Group
Jun 25, 2014
I have a pretty complex query that returns three records. For simplicity sake, the results can be simulated with this query:
Select 5 AS InternalAuditTeamEmployeeID, 1 as InternalAuditTeamID
UNION ALL
Select 11, 2
UNION ALL
Select 14, 3;
I want to take this result and update the Flag field to true in my table tblInternalAuditTeamEmployee (CREATE statement below) for any InternalAuditTeamEmployeeID that is less than or equal to the ones in the results above, but by group. My results would look something like this using the data below and the results above.
I was thinking I could somehow use ROW_NUMBER(PARTITION BY InternalAuditTeamID ORDER BY InternalAuditTeamEmployeeID DESC), but not sure how to get the results of "WHERE <= InternalAuditTeamEmployeeID For each particular group".
CREATE TABLE STATEMENT:
CREATE TABLE [tblInternalAuditTeamEmployee](
[InternalAuditTeamEmployeeID] [int] IDENTITY(1,1) NOT NULL,
[InternalAuditTeamID] [int] NOT NULL,
[EmployeeID] [int] NOT NULL,
declare @Sample table (ID int, message varchar(1000)) insert into @Sample(ID,message) select 1,'Testing 1' union all select 1,'Testing 2' union all select 1,'Testing 3' union all
[Code] ....
I need to get top three values has to be comma separated. for example id 1 has 5 rows message which comma separated. Instead i need to consider top three message group by Id
How to identify different fields with in a group of records?
Example: create table #test (ID int, Text varchar(10)) insert into #test select 1, 'ab' union all select 1, 'ab'
[Code] ...
I want to show additional field as Matched as ID 1 has same Text field on both the records, and for the ID 2 I want to show Unmatched as the Text fields are different but with the same ID.
I'm bulk loading employees into an etl table, each employee has a unique ID number, but they have multiple records in the data. Sometimes their name or birthdate will change and I want to identify those records and only insert the newest version into production. I can do this with a series of temp tables, but I'm sure there's a better way. The SQL below updates the etl table with the flag I want to mark the inserts, but it seems convoluted. (Jon's birthday changes, Jane's birthday changes, Bill's gender changes, Amy nothing changes(I handle those inserts later))
I have an address table, and a log table will only record changes in it. So we wrote a after udpate trigger for it. In our case the trigger only need to record historical changes into the log table. so it only needs to be an after update trigger.The trigger works fine until a day we found out there are same addresses exist in the log table for the same student. so below is what I modified the trigger to. I tested, it seems working OK. Also would like to know do I need to use if not exists statement, or just use in the where not exists like what I did in the following code:
ALTER TRIGGER [dbo].[trg_stuPropertyAddressChangeLog] ON [dbo].[stuPropertyAddress] FOR UPDATE AS DECLARE @rc AS INT ;
I have a query that brings back the data below. I need to divide the BudgetTotal by the Count. Then I need to go to the records that make up those €śgroups€? and enter a Budget value = BudgetTotal/Count.
How could I write this in a stored procedure or a SQL statement if possible?
Thanks.

I am trying to find a way to add into a table a flattened (comma seperated list) of email addresses based on the multiple columns of nformation in another table (joined by customer_full_name and postcode.
This is to highlight duplicate email addresses for people under the same customer_full_name and Postcode.
I have done this using a loop which loops through concatenating the email addresses but it takes 1minute to do 1000. The table is 19,000 so this isn't really acceptable. I have tried temp tables, table variables and none of this seems to make any difference. I think that it is becuase i am joining on text columns?
I need to normalise comma separated strings of tags (SQL Server 2008 R2).
E.g. (1, 'abc, DEF, xyzrpt') should become (1, 'abc') (1, 'DEF') (1, 'xyzrpt')
I have written a procedure in T-SQL that can handle this. But it is slow and it would be better if the solution was available as a view, even a slow view would be better.
Most solutions I found go the way round: from (1, 'abc'), (1, 'DEF') and (1, 'xyzrpt'), generate (1, 'abc, DEF, xyzrpt').
If memory serves, it used "FOR XML PATH". But it's been a while and I may be totally wrong.
I have a table with about half a million records, each representing a patient in my county.
Each record has a field (RRank) which basically sorts the patients as to how "unwell" they are according to a previously-applied algorithm. The most unwell patient has an RRank of 1, the next-most unwell has RRank=2 etc.
I have just deleted several hundred records (which relate to patients now deceased) from the table, thereby leaving gaps in the RRank sequence. I want to renumber the remaining recs to get rid of the gaps.
I can see what I want to accomplish by using ROW_NUMBER, thus:
SELECT ROW_NUMBER() Over (ORDER BY RRank) as RecNumber, RRank FROM RPL ORDER BY RRank
I see the numbers in the RecNumber column falling behind the RRank as I scan down the results
My question is: How to convert this into an UPDATE statement? I had hoped that I could do something like:
UPDATE RISC_PatientList_TEMP SET RRank = ROW_NUMBER() Over (ORDER BY RRank);
but the system informs that window functions will only work on SELECT (which UPDATE isn't) or ORDER BY (which I can't legally add).
We have a medium sized database with the next tables:
- PA: 525000 records - PR: 780000 records - R: 1000 records - B: 45 records
PA: PK = PAARDCODE
PR: PK = PAARDREGISTERCODE PR: FK = PAARDCODE PR: FK = REGISTERCODE
R: PK = REGISTERCODE R: FK = BOEKCODE
B: PK = BOEKCODE
When I group by B.BOEKCODE the query lasts: 10 (or more when 'where' option is added) seconds When I group by R.BOEKCODE the query lasts less than 2 seconds.
SELECT B.BOEKOMSCHRIJVING, B.BOEKCODE -- or R.BOEKCODE FROM PA INNER JOIN PR ON PA.PAARDCODE = PR.PAARDCODE INNER JOIN R ON R.REGISTERCODE = PR.REGISTERCODE INNER JOIN B ON R.BOEKCODE = B.BOEKCODE GROUP BY BOEKOMSCHRIJVING, B.BOEKCODE -- or R.BOEKCODE ORDER BY BOEKOMSCHRIJVING Why is the option of B.BOEKCODE a lot slower compared to R.BOEKCODE?
Table Clients is master table with all records, joining against Assets table that may or may not have a matching entry.
Trying to sum an asset type against table and no matter what kind of join I do I cannot get SQL to return a NULL match against the Clients ID value. All I get back are matching rows.
Here's the SQL:
select c.cindex,SUM(a.value) AS 'Total Assets' from Clients c "the join" Assets2012 a on a.clientid=c.cindex where (c.ClientClass<=7 AND c.ClientClass<>6) AND a.assettype = 2 group by c.cindex
But no matter what type of join I do, left, right, left outer, inner, I am not getting back NULL values for client records that have no matching asset records.
Strange thing is, by removing the "and assettype=2" part I get the whole database back, with NULL's but not the range I'm looking for.
I need a little help here..I want to transfer ONLY new records AND update any modified recordsfrom Oracle into SQL Server using DTS. How should I go about it?a) how do I use global variable to get max date.Where and what DTS task should I use to complete the job? Data DrivenQuery? Transform data task? How ? can u give me samples. Perhaps youcan email me the Demo Package as well.b) so far, what I did was,- I have datemodified field in my Oracle table so that I can comparewith datelastrun of my DTS package to get new records- records in Oracle having datemodified >Max(datelastrun), and transferto SQL Server table.Now, I am stuck as to where should I proceed - how can I transfer theserecords?Hope u can give me some lights. Thank you in advance.
I have a table with a text field and a grouping number.
1, A 1, B 1, C 1, D 1, E
2, A 2, C 2, D 2, E
3, A 3, B 3, C 3, F
4, A 4, B 4, D 4, F 4, G
I assemble the text fields into strings by group, using the FOR XML PATH('') function, so that I end up with
1, A-B-C-D-E 2, A-C-D-E 3, A-B-C-F 4, A-B-D-F-G
This all works fine. I now have a requirement to leave out some groups, based on whether the GROUP does or does not contain a certain text. For instance, if I want only GROUPS with 'E', my result set should be
1, A-B-C-D-E 2, A-C-D-E
If I want only those GROUPS that DO NOT have 'E', my result set should be
3, A-B-C-F 4, A-B-D-F-G
I can (and have) put a condition on the assembled string, but it seems to me that it should be possible to make the cut earlier. That is, rather than assembling the string, scanning it with a Like '%E%' condition and discarding what doesn't meet my needs, I would like to stop scanning the incoming GROUP as soon as a mismatch is detected.
If I want all groups that will not contain an 'A', for instance, it is pointless for the query engine to read in 'A', 'B', 'C', 'D', 'E', put them all together into a string, compare it with a wildcard and throw it away. As soon as it sees the 'A', it has enough information to completely skip over the rest of that group. The abbreviated examples here are trivial, but the real code is not.
All I've been able to dream up so far results in skipping the RECORD that contains the 'A', but not the entire group.
CREATE TABLE #Turnover ( location varchar(50), Total int )
insert into #Turnover (location,Total) values('A', 500) insert into #Turnover (location,Total) values('AB', 200) insert into #Turnover (location,Total) values('ABC', 100) insert into #Turnover (location,Total) values('BA', 100) insert into #Turnover (location,Total) values('BAC', 500) insert into #Turnover (location,Total) values('BAM', 100)
Now i want output order by total but same time i want to create two groups. i.e. location starting with A and order by total and after locations starting with B and order by total.
I've got a fairly standard query that does a group by a type column, and then sums the lengths of a VARCHAR column. I'd like to add into that a concatenated version of the string always concatenating in primary key order. Is that possible?
Is it possible to check for Active Directory group.. ie see if the user running the Stored Proc, is in a specific Active Directory Group? Or if I set up Login's using Active Directory, can I get the Login that way... or will it give me the user's account?
I'm trying using the GROUP BY CUBE aggregation. Currently I have this working as such:
SELECT ISNULL(CONVERT(VARCHAR,Date), 'Grand Total') Date ,ISNULL([1 Attempt],0) [1 Attempt] ,ISNULL([2 Attempts],0) AS [2 Attempts] ,ISNULL([3 Attempts],0) AS [3 Attempts] ,ISNULL([4 Or More],0) AS [4 Or More]
[Code] .....
Basically this is used to work similar to a Pivot table in excel. My data will look as follows:
Date 1 Attempt2 Attempts3 Attempts4 Or MoreTotal 2012-09-04 239 68 2 8 317
The problem I'm having is the Total column. Although this is summing the line values correctly, the total should be based on the sum not count of attempts i.e. 1 x 239, 2 x 68, 3 x 2, 4 x 8
If I change the FROM select clause to use SUM instead of COUNT
SELECT CONVERT(DATE,[Date]) Date ,ISNULL(AttemptsFlag,'Total') as Attempt ,SUM(NoOfTimes) AS Totals FROM XXXXX GROUP BY CUBE([Date],AttemptsFlag)
It will return the correct Total amount but not the right numbers for the Attempt groupings...
We sell & ship packages that contain multiple items within them. The actual package (we call it the "parent item") is in the same table as the items within it ("child items"). If the record is a child item within a package, its "ParentId" field will contain the ItemId of the package.
So some sample records of a complete package would look like this:
ItemId's 2 & 3 are items contained within the ItemId 1 package.
Now however, the client wants us to build a report showing all packages (all items where ParentId is NULL) however, they want to see the QtyAvailable of not only the package but the items as well (a total of 15 when using the example above), all grouped into a single line. So a sample report line would look like this:
Name | Available Qty -------------------------- Package A | 15 Package B | 100
How can I do a SELECT statement that SUMS the "QtyAvailable" of both the parent & child items and displays them along with the package name?
In Outer join, I would like to add the outer columns that don't exist in the right table for each order number. So currently the columns that don't exist in the right table only appear once for the entire set. How can I go about adding PCity, PState to each order group, so that PCity and PState would be added as null rows to each group of orders?
if OBJECT_ID('tempdb..#left_table') is not null drop table #left_table; if OBJECT_ID('tempdb..#right_table') is not null drop table #right_table; create table #left_table
For code reuse, I am trying to get a table valued function to return users of a given AD group name. I can easily get this with hard-coding the group name. But because OpenQuery wont accept parameters, I can't insert my group name there. And because functions can't call dynamic SQL, I can't do it via dynamic sql. I have seen people do it with CLR, but I rather not go that route. I can use a stored procedure + cursor and iterate through each group and store the results into real tables and create a cache, but I rather query Active Directory itself to save space, but I rather do the caching then the CLR. Any approach I am missing on how to do this?
The following works fine:
SELECT DISTINCT sAMAccountName FROM OPENQUERY(ADSI, 'SELECT sAMAccountName, sn FROM ''LDAP://OU=SomeOU,OU=SomeOtherOU,DC=SomeDC,DC=SomeOtherDC'' WHERE objectCategory=''Person'' AND objectClass=''USER'' AND memberOf=''CN=SomeGroupName,OU=SomeOU,OU=SomeOtherOU,DC=SomeDC,DC=SomeOtherDC''') a WHERE sn IS NOT NULL
The following gives me the error:

I'd like to find the record in table #1 "Matter" which has exact record of "GID" in table #3 "Security Assignment" compare with table #2 "Category"
In this case, it is record of "002" bacause "002" in table#1 "Matter" and the record "a" in table #2 "category" both has exact GID records(g01, g02, g03) in table #3, "Security Assignment"
How can I create qury to find all the possible record in the table #2?
I need to query to return a result for each unique machine with the latest date. The example result below would be returned because they have the latest date.
MachineA 5/7/2011 MachineB 5/5/2010
Select Distinct would almost do it, but I need each unique machine that has the latest date.
tblPerson - holds basic person data. tblPersonHistorical - holds a dated snapshot of the fkPersonId, fkInstitutionId, and fkDepartmentId tblWebUsers - holds login data specific to a web account, but not every person will have a web account
I want to allow my admins to search for users (persons) with web accounts. They need to be able to search by tblPerson.FirstName, tblPerson.LastName, tblInstitutions.Institution, and tblDepartments.Department. The only way a Person record is joined an Institution or Department record is through many -> many junction table tblPersonHistorical.
People place orders and make decisions in our system. Because people can change institutions and departments, we need an historical snapshot of where they worked at the time they placed an order or made a decision. Of course that means some folks will have multiple historical records. That all works fine.
So when an admin user wants to search for webusers, I only want to return data, if possible, from he most recent/current historical records. This is where I am getting bogged down. When I search for a specific webuser I simply do a TOP 1 and ORDER BY DateCreated DESC. That returns only the current historical record for that person/webuser.
But what if I want to return many different webusers, and only want the TOP 1 historical for each returned?
Straight TOP by itself won't do it. GROUP BY by itself won't do it.
