T-SQL (SS2K8) :: Group By With Nulls?
Jun 12, 2015
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'm working on a join between two tables where I only want one row returned... I'm matching on two columns between two tables. One of those columns in the target table could be null. I only want one record returned.
create table #vehicle(id int, vehiclemake varchar(10), vehiclemodel varchar(10), classtype varchar(1))
create table #class(id int, classtype varchar(1), value int)
insert into #vehicle values(1, 'AUDI', 'R8', 'A')
insert into #vehicle values(2, 'AUDI', null, 'B')
insert into #class values(1, 'A', 100)
insert into #class values(2, 'B', 1)
[Code] ....
Using the above example, if VehicleModel is anything other than 'R8' is specified then I want it to return the other class type record.
This is going to be used as a join within a bigger statement, so I'm not sure ordering and returning top 1 is going to work.

I have been away from SQL for a couple of months, and for the life of me cannot work out a simple way to do what i want to do.
select bu1.name,bu2.name, bu3.name, bu4.name, bu5.name
from
Sale
INNER JOIN
Sysuser on sale.userid = sysuser.userid
INNER JOIN businessunitBU1
on BU1.Businessunitid = sysuser.businessunitid
left JOIN businessunitBU2
on BU2.Businessunitid = bu1.parentbusinessunitid
left JOIN businessunitBU3
on BU3.Businessunitid = bu2.parentbusinessunitid
left JOIN businessunitBU4
on BU4.Businessunitid = bu3.parentbusinessunitid
left JOIN businessunitBU5
on BU5.Businessunitid = bu4.parentbusinessunitid
So effectively i am trying to go through the hierarchy to find all the levels. Unforunately not every entry has the same amount of levels.
So its coming out like this.....
Bu1 BU2 BU3 BU4 BU5
L5 L4 L3 L2 L1
L4 L3 L2 L1
L3 L2 L1
L5 L4 L3 L2 L1
So whats the easiest way to move everything along to fill in the blanks, but move the blanks to the end - so it would be more like this:
Bu1 BU2 BU3 BU4 BU5
L5 L4 L3 L2 L1
L4 L3 L2 L1
L3 L2 L1
L5 L4 L3 L2 L1

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?

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.

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.
InternalAuditTeamEmployeeIDInternalAuditTeamIDEmployeeIDFlag
1 1 619 1
218581
316041
425181

1012340
1129541
1228910
1329500
143321
1539450
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](

[InternalAuditTeamID] [int] NOT NULL,
[EmployeeID] [int] NOT NULL,

Given the following example;
declare @CustIfno table (AccountNumber int, StoreID int, Distance decimal(14,10))
insert into @CustIfno values ('1','44','2.145223'),('1','45','4.567834'),

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 | ParentId | Name | QtyAvailable
----------------------------------------
1 | NULL | Package A | 10
2 | 1 | Item 1 | 2
3 | 1 | Item 2 | 3
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:
Invalid use of a side-effecting operator 'EXECUTE STRING' within a function.
CREATE FUNCTION [dbo].queryADGroupMembers

I have two SSIS packages that import from the same flat file into the same SQL 2005 table. I have one flat file connection (to a comma delimited file) and one OLE DB connection (to a SQL 2005 Database). Both packages use these same two Connection Managers. The SQL table allows NULL values for all fields. The flat file has "empty values" (i.e., ,"", ) for certain columns.
The first package uses the Data Flow Task with the "Keep nulls" property of the OLE DB Destination Editor unchecked. The columns in the source and destination are identically named thus the mapping is automatically assigned and is mapped based on ordinal position (which is equivalent to the mapping using Bulk Insert). When this task is executed no null values are inserted into the SQL table for the "empty values" from the flat file. Empty string values are inserted instead of NULL.
The second package uses the Bulk Insert Task with the "KeepNulls" property for the task (shown in the Properties pane when the task in selected in the Control Flow window) set to "False". When the task is executed NULL values are inserted into the SQL table for the "empty values" from the flat file.
So using the Data Flow Task " " (i.e., blank) is inserted. Using the Bulk Insert Task NULL is inserted (i.e., nothing is inserted, the field is skipped, the value for the record is omitted).
I want to have the exact same behavior on my data in the Bulk Insert Task as I do with the Data Flow Task.
Using the Bulk Insert Task, what must I do to have the Empty String values inserted into the SQL table where there is an "empty value" in the flat file? Why & how does this occur automatically in the Data Flow Task?
From a SQL Profile Trace comparison of the two methods I do not see where the syntax of the insert command nor the statements for the preceeding captured steps has dictated this change in the behavior of the inserted "" value for the recordset. Please help me understand what is going on here and how to accomplish this using the Bulk Insert Task.

I have an SSRS 2012 table report with groups; each group is broken ie. one group for one page, and there are multiple groups in multiple pages.
'GroupName' column has multiple values - X,Y,Z,......
I need to group 'GroupName' with X,Y,Z,..... ie value X in page 1,value Y in page 2, value Z in page 3...
Now, I need to display another column (ABC) in this table report (outside the group column 'GroupName'); this outside column itself is another column header (not a group header) in the table (report) and it derives its name partly from the 'GroupName' values:
Example:
Value X for GroupName in page 1 will mean, in page 1, column Name of ABC column must be ABC-X Value Y for GroupName in page 2 will mean, in page 2, column Name of ABC column must be ABC-Y Value Z for GroupName in page 3 will mean, in page 3, column Name of
ABC column must be ABC-Z
ie the column name of ABC (Clm ABC) must be dynamic as per the GroupName values (X,Y,Z....)
Page1:
GroupName Clm ABC-X
X
Page2:
GroupName Clm ABC-Y
Y
Page3:
GroupName Clm ABC-Z
Z
I have been able to use First(ReportItems!GroupName.Value) in the Page Header to get GroupNames displayed in each page; I get X in page 1, Y in page 2, Z in page 3.....
However, when I use ReportItems (that refers to a group name) in the Report Body outside the group,
I get the following error:
Report item expressions can only refer to other report items within the same grouping scope or a containing grouping scope
I need to get the X, Y, Z ... in each page for the column ABC.
I have been able to use this - First(Fields!GroupName.Value); however, I get ABC-X, ABC-X, ABC-X in each of the pages for the ABC column, instead of ABC-X in page 1, ABC-Y in page 2, ABC-Z in page 3, ...

Hi!
I've posted a feedback with Microsoft to see if we can get them to fix the issue described below, but so far no one from Microsoft has commented to let us know what they're doing about this problem! I'm posting this here to see if maybe we can get more people to rate this feedback or chime in on what a pain it is! Please feel free to add your own comments or how you had to work around this issue and whether or not you think this is something Microsoft should be addressing NOW.

Provide Individual Page Numbering per Group and Total Pages per Group
Currently in a Reporting Services report, you can't readily reset the page number for each group in a table, nor can you display the total number of pages per group. For example, if I'm printing invoices and each invoice is a separate group, I'd like to be able to print "Page 1 of 5" , "Page 2 of 5" etc. for the first invoice, then "Page 1 of 3" when the next invoice begins, and so on. This was easy in Crystal Reports. I realize that Crystal Reports has a two-pass process that enables that kind of pagination. However, this is REALLY important functionality that's just missing from Reporting Services and I'm hoping you'll provide it REALLY SOON! Yeah, I know there are work-arounds if you can know exactly how many rows of information there are on each page. But gosh! That's not practical, especially if you have second level groups inside the main group or text blocks in rows that can 'grow' to more than one line. I've read a couple of work-arounds, but none of them works correctly and consistently when more than one user is running the same report or when you print the report while you're looking at it on the screen. I still may need access to the overall report page number and the overall total number of pages, so don't get rid of that. It's just that if you're doing this already for the entire report, I don't see why you can't do it per group! Lots of people have been asking for this for years, and I don't understand why it hasn't been implemented.
I've read a few articles on this topic, but no one has come up with a decent work around. My theory is that Microsoft should be addressing this immediately. This is major functionality that's just plain missing from SSRS and should have been there from the start. If anyone from Microsoft can let us know what's going on with this issue or if anyone would like for me to clarify this further, feel free to let me know.
Thanks!

I'm having a fight with Reporting Services at the minute when trying to compute an average at the row group level for a value summed in a column group.I have the following column groups:
Year
Month
Date
And the following row groups:
Region
Product
SubType (hidden, data at the date level is summed to Product)
At the moment I'm computing the average for SubType for each Date at the Product level (giving a decimal value), so for each day I end up with a nice average, that works. However I am unable to average that average over the whole Year for a Product. The issue being that I'm trying to combine Row Groups (Product) and Column Groups (Date/Year)

I have a need to show a row inside a table group to simulate a header row for the data rows inside the group. The table will not have a real header or footer. Thanks for the help.
