Data Access :: How To Do Grouping Using Three Columns
Oct 7, 2015
I am using sql table named as product which is having columns partno,partnm,weight,surfacearea,totalhr,type
I want sum of weight,surfacearea,totalhr and grouping on partno,partnm,type
If I use query select partno,partnm,sum(weight),sum(surfacearea),sum(totalhr) from product GROUP BY partno,partnm then its working correctly with sum and grouping but if I use query select partno,partnm,sum(weight),sum(surfacearea),sum(totalhr),type from product  GROUP BY partno,partnm,type then it is not grouping as expected.
why if third column included in group by clause its not working correctly...Is there any way to group as I want.

Till recently we were using the following code to retreive schema information of columns of tables
Dim schemaTable = connection.GetOleDbSchemaTable( _
System.Data.OleDb.OleDbSchemaGuid.Columns, _
New Object() {Nothing, Nothing, tableName, Nothing})
Now instead of getting the name of table (which i was using as param for filtering) i'm going to receive a sql-query. Now my question is if I were to get a query like the following :
SELECT
[EmployeeID],
[Title] + ' ' + [LastName] + ' ' + [FirstName] AS FullName,
[BirthDate],
[Address],
[City] + ', ' + [Region] + ', ' + [Country] + ' - ' + [PostalCode] AS FullAddress
FROM [dbo].[Employees]
Then how can I retrieve the schema information of only the columns present in the query.
(Its possible that i might get a query with multiple tables with joints)...

Hello guys !!
I'm actually a Mysql user, not a SQL Server user, just becouse the business I work uses it. But the problem I've had I think doesn't have any relation on the plataform it's running...
This is a construction software... I'll try my best to explain you : My table has 4 main columns (Face,Station,Combination,sAs). Face , Station and Combination form a primary key (never repeat together) and the "sAs" represents a calculus between some parameters.
The problem (it became a challenge already :D) consists in selecting the Face,Station and Combination where sAs is maximus, BUT grouping ONLY Face and Station.
For example :
Face Station Combination sAs
F1 0 Comb1 45
F1 0 Comb2 13
F1 0 Comb3 30
---
F1 10 Comb1 42
F1 10 Comb2 60
F1 10 Comb3 12
---
F2 0 Comb1 32
F2 0 Comb2 15
F2 0 Comb3 01
---
F2 10 Comb1 02
F2 10 Comb2 07
F2 10 Comb3 23
Here is the challenge :
If you execute the following query : "select Face,Station,Combination,max(sas) as sAS from test group by Face,Station" it returns you an arbitrary Combination for the rows in the resultset.
Face Station Combination sAs
F1 0 Comb1 45
F1 10 Comb1 60
F2 0 Comb1 32
F2 10 Comb1 23
But the combination I'd like to have is the combination related to the maximus sAs in F1/10, Comb2 instead of Comb1 returned..... The same occurs with the last row F2/10.
The query I wanna find should return the following resultset.
Face Station Combination sAs
F1 0 Comb1 45
F1 10 Comb2 60
F2 0 Comb1 32
F2 10 Comb3 23
Please, if somebody has any idea, share it to help me....
Thanks a lot..
Rodrigo
Some code to make it easier to try.... Maybe it has some difference between SQL Server and MySQL.
////////////// CUT HERE
create table test(
Face varchar(20),
Station int,
Combination varchar(20),
sAs int
);
insert into test values('F1', 0, 'Comb1', 45);
insert into test values('F1', 0, 'Comb2', 3);
insert into test values('F1', 0, 'Comb3', 30);
insert into test values('F1', 10, 'Comb1', 42);
insert into test values('F1', 10, 'Comb2', 60);
insert into test values('F1', 10, 'Comb3', 12);
insert into test values('F2', 0, 'Comb1', 32);
insert into test values('F2', 0, 'Comb2', 15);
insert into test values('F2', 0, 'Comb3', 01);
insert into test values('F2', 10, 'Comb1', 02);
insert into test values('F2', 10, 'Comb2', 07);
insert into test values('F2', 10, 'Comb3', 23);
select Face,Station,Combination,max(sas) as sAS from test group by Face,Station;

Hi,
I just read on web that we can not use grouping columns in a variable when using PIVOT operator. For example like,
USE AdventureWorks
GO
SELECT VendorID, [164] AS Emp1, [198] AS Emp2, [223] AS Emp3, [231] AS Emp4, [233] AS Emp5
FROM
(SELECT PurchaseOrderID, EmployeeID, VendorID
FROM Purchasing.PurchaseOrderHeader) p
PIVOT
(
COUNT (PurchaseOrderID)
FOR EmployeeID IN
( [164], [198], [223], [231], [233] ) // cannot put these in a variable like @Col
) AS pvt
ORDER BY VendorID;
Though it can be achieved using when making the query using dynamic sql. If some can make it clear why it is possible using dynamic sql and not with the above code.

I think I am definitely thrashing and am not getting anywhere on something I think should be pretty simple to accomplish: I need to pull the total amounts for compartments with different products which are under the same manifest and the same document number conditionally based on if the document types are "Starting" or "Ending" but the values come from the "Adjust" records.
So here is the DDL, sample data, and the ideal return rows
CREATE TABLE #InvLogData
(
Id BIGINT, --is actually an identity column
Manifest_Id BIGINT,
Doc_Num BIGINT,
Doc_Type CHAR(1), -- S = Starting, E = Ending, A = Adjust
Compart_Id TINYINT,
[Code] ....
I have tried a combination of the below statements but I keep coming back to not being able to actually grab the correct rows.
SELECT DISTINCT(column X)
FROM #InvLogData
GROUP BY X
HAVING COUNT(DISTINCT X) > 1
One further minor problem: I need to make this a set-based solution. This table grows by a couple hundred thousand rows a week, a co-worker suggested using a <shudder/> cursor to do the work but it would never be performant.

I'm trying to re-write my database to de-couple the interface (MS Access) from the SQL Backend. Â As a result, I'm going to write a number of Stored Procedures to replace the MS Access code. Â My first attempt worked on a small sample, however, trying to move this on to a real table hasn't worked (I've amended the SP and code to try and get it to work on 2 fields, rather than the full 20 plus).It works in SQL Management console (supply a Client ID, it returns all the client details), but does not return anything (recordset closed) when trying to access via VBA code.The Stored procedure is:-
USE [VMSProd]
GO
/****** Object: StoredProcedure [Clients].[vms_Get_Specified_Client] Script Date: 22/09/2015 16:29:59 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
[code]....

I have a set of data that contains duplicates and I am running a group by query to get a unique set of rows.
The group by works upto a certain state, but I need to be able to tell it to take the first appearance of an address field as you can in Access?
current query is:
select ID,Address1,max(value)
from test
group by id,address1
I have tried using First(Address1) but it doesn't recognise that as a function?

Hi Everyone,
I am trying to develop a report query that will dynamically group the data by day,week, quarter, month, or year. The user will select the interval from the site and pass it to the query. The query will convert the date field using a function I created. Is this the most efficient way to do this?
QUERY
------------------
SELECT dbo.FormatDate(DateCreated,3) As DateCreated, Count(*) As NumOfCalls
FROM Agent.LeadTracker
WHERE DateCreated BETWEEN '1/1/2008' AND '2/7/2008'
GROUP BY dbo.FormatDate(DateCreated,3)
RESULT
------------------
DateCreated NumOfCalls
2008-02-01 5442
2008-01-01 14150
FUNCTION------------------
CREATE FUNCTION [dbo].[FormatDate]
(
@Date datetime,
@Time int
)
RETURNS datetime
AS
BEGIN
DECLARE @Res datetime
IF @Time = 1 --Day
SELECT @Res = DATEADD(day,DATEDIFF(day,0,@Date),0)
ELSE IF @Time = 2 --Week
SELECT @Res = DATEADD(week,DATEDIFF(week,0,@Date),0)
ELSE IF @Time = 3 --Month
SELECT @Res = DATEADD(month,DATEDIFF(month,0,@Date),0)
ELSE IF @Time = 4 --Quarter
SELECT @Res = DATEADD(quarter,DATEDIFF(quarter,0,@Date),0)
ELSE IF @Time = 5 --Year
SELECT @Res = DATEADD(year,DATEDIFF(year,0,@Date),0)
RETURN @Res

I'm really stumped on this one. I'm a self taught SQL guy, so there is probobly something I'm overlooking.
I'm trying to get information like this in to a report:
WO#
-WO Line #
--(Details)
--Work Order Line Detail #1
--Work Order Line Detail #2
--Work Order Line Detail #3
--Work Order Line Detail #etc
--(Parts)
--Work Order Line Parts #1
--Work Order Line Parts #2
--Work Order Line Detail #etc
WO#
-WO Line #
--(Details)
--Work Order Line Detail #1
--Work Order Line Detail #2
--Work Order Line Detail #3
--Work Order Line Detail #etc
--(Parts)
--Work Order Line Parts #1
--Work Order Line Parts #2
--Work Order Line Parts #etc
I'm unable to get the grouping right on this. Since the line details and line parts both are children of the line #, how do you do "parallel groups"?
There are 4 tables:
Work Order Header
Work Order Line
Work Order Line Details
Work Order Line Requisitions
The Header has a unique PK.
The Line uses the Header and a Line # as foreign keys that together are unique.
The Detail and requisition tables use the header and line #'s in addition to their own line number foreign keys. My queries ends up looking like this:
WO WOL WOLR WOLD
226952 10000 10000 10000
226952 10000 10000 20000
226952 10000 10000 30000
226952 10000 10000 40000
226952 10000 20000 10000
226952 10000 20000 20000
226952 10000 20000 30000
226952 10000 20000 40000
399999 10000 NULL 10000
375654 10000 10000 NULL
etc
Hierarchy:
WO > WOL > WOLD
WO > WOL > WOLR
It probobly isn't best practice, but I'm kinda new so I need some guidance. I'd really appreciate any help! Here's my query:
SELECT [Work Order Header].No_ AS WO_No, [Work Order Line].[Line No_] AS WOL_No,
[Work Order Requisition].[Line No_] AS WOLR_No, [Work Order Line Detail].[Line No_] AS WOLD_No
FROM [Work Order Header] LEFT OUTER JOIN
[Work Order Line] ON [Work Order Header].No_ = [Work Order Line].[Work Order No_] LEFT OUTER JOIN
[Work Order Line Detail] ON [Work Order Line].[Work Order No_] = [Work Order Line Detail].[Work Order No_] AND
[Work Order Line].[Line No_] = [Work Order Line Detail].[Work Order Line No_] LEFT OUTER JOIN
[Work Order Requisition] ON [Work Order Line].[Work Order No_] = [Work Order Requisition].[Work Order No_] AND
[Work Order Line].[Line No_] = [Work Order Requisition].[Work Order Line No_]

I have a business need to create a report by query data from a MS SQL 2008 database and display the result to the users on a web page. The report initially has 6 columns of data and 2 out of 6 have JSON data so the users request to have those 2 JSON columns parse into 15 additional columns (first JSON column has 8 key/value pairs and the second JSON column has 7 key/value pairs). Here what I have done so far:
I found a table value function (fnSplitJson2) from this link [URL]. Using this function I can parse a column of JSON data into a table. So when I use the function above against the first column (with JSON data) in my query (with CROSS APPLY) I got the right data back the but I got 8 additional rows of each of the row in my table. The reason for this side effect is because the function returned a table of 8 row (8 key/value pairs) for each json string data that it parsed.
1. First question: How do I modify my current query (see below) so that for each row in my table i got back one row with 19 columns.
SELECT A.ITEM1,A.ITEM2,A.ITEM3,A.ITEM4, B.*
FROM PRODUCT A
CROSS APPLY fnSplitJson2(A.ITEM5,NULL) B
If updated my query (see below)Â and call the function twice within the CROSS APPLY clause I got this error: "The multi-part identifier "A.ITEM6" could be be bound.
2. My second question: How to i get around this error?
SELECT A.ITEM1,A.ITEM2,A.ITEM3,A.ITEM4, B.*, C.*
FROM PRODUCT A
CROSS APPLY fnSplitJson2(A.ITEM5,NULL) B, Â fnSplitJson2(A.ITEM6,NULL) C
I am using Microsoft SQL Server 2008 R2 version. Windows 7 desktop.

1/7/2007 250.00

1/6/2007 50.00
100.00 350.00
Sam 1/6/2007 50.00
0 50.00
Because the deposit and withdrawal data is only related by customer, I€™ve broken it into 2 datasets.
I€™m totally stumped! Can someone get me going in the right direction on this?

Hello all
I am using SQL Server 2000. I have a table of over 1 million accounting transactions. I need to be able to remove all items that have contra items.
e.g
debit £100 - credit £100 - debit of £125 ( I only want to see the debit of £125)
I can achieve this in MS Access by grouping the key fields, suming the value fields and using the First() or Last() command for columns that I need to display but not group.
How can I achieve this in SQL?
All help appreciated.

Here's another one of my bitchfest about stuff which annoy the *** out of me in SSIS (and no such problems in DTS):
Do you ever wonder how easy it was to set up text file to db transform in DTS - I had no problems at all. In SSIS - 1 spent half a day trying to figure out how to get proper column data types for text file - OF Course MS was brilliant enough to add "Suggest Types" feature to text file connection manager - BUT guess what - it sample ONLY 1000 rows - so I tried to change that number to 50000 and clicked ok - BUT ms changed it to 1000 without me noticing it - SO NO WONDER later on some of datatypes did not match. And boy what a fun it is to change the source columns after you have created a few transforms.
This s**hit just breaks... So a word about Derived Columns - pretty useful feature heh? ITs not f***ing useful if it DELETES SOME of the Code itself after there have been changes in dataflow. I cant say how pissed off im about that SSIS went ahead and deleted columns from flow & messed up derived columns just because the lineageIDs dont match.
Meta-data - it would be useful if you could change it and refresh it - im just sick and tired of it that it shows warnings and errors when there's nothing wrong - so after a change i need to doubleclick all my transforms so that those red & yellow boxes would disappear.
Oh and y I passionately dislike Derived columns - so you create new fields based on some data - you do some stuff - combine multiple columns to one, but you have no way saying remove the columns from the pipeline. Y you need it - well if you have 50K + rows with 30+ columns then its EXTRA useless memory overhead for your package.
Hopefully one day I will understand how SSIS works (not an ez task I say) - I might be able to spend more time on development and less time on my bitchfest - UNTIL then --> Another Day - Another Hassle with SSIS

Hello,
I have a table similar to the following (XYZ). I would like to write a select statement that will return the count of the unique items for each user that also happen to be less than 1 year old. The less than one year old part is rather easy dateadd(year, -1, getdate()), but I seem to be having a hard time figuring out how to get my desired result without using subselects. Any help greatly appreciated. Thanks in advance - Dan.
So my goal results are:
User Count
Dan 2
Dave 1
Table XYZ
ID User Item Value Date
1 Dan 1 20 5/5/2007
2 Dan 1 30 6/5/2007
3 Dave 2 25 6/1/2007
4 Dan 2 22 5/1/2007
5 Dan 3 23 5/1/2006

Hi Fellows
I am trying to organize these information.the data come form two tables that are not relating, but I did a join and my primary key is the filed polygon. I have a list of points(geomseq) for each polygon but the number of points(geomseq) can change. I have this inofrmation in a data base.
geomseq polygon xc yc x1 y2
0 17 21 22.5 0 0
3 17 21 22.5 40 40
2 17 21 22.5 0 20
4 17 21 22.5 20 0
1 17 21 22.5 0 10
5 17 21 22.5 10 10
1 18 40 40.5 0 20
4 18 40 40.5 20 30
0 18 40 40.5 0 0

9 18 40 40.5 80 80
7 18 40 40.5 45 45
8 18 40 40.5 50 60
I want something like this
geomseq polygon xc yc x1 y2

I have what at first site should be a simple reporting services issue but cannot resolve:-
I have a complex report comprising over 90 pages of various sections but when analysed in detail , 80% of it follows a simple pattern i.e. it comprises around 100 instances of the same sub-report bound to the same data source BUT grouped and filtered on different groupings and filter values.
The pattern is as follows:-
Each sub-report instance is bound to an SSAS cube which has fields L1, L2...L7
Each sub-report instance groups the data dynamically by one or more groups G1,G2..G7, the actual fields to be used being defined by the parent report (i.e. one instance may group by fields L7, L3, L4, another by L2,L3 etc)
Each sub-report instance has up to 7 filters defined (F1..F7) may filter the data i.e. the parent may pass a filter stipulating that L7="A", L3="B". To do this, the parent sets filter parameters F7="A" and F3="B"
The approach I have adopted is to set up parameters in the sub-report for dynamically grouping the data i.e. the
sub-report has 7 parameters defined G1..G7 and the parent report populates G1..G7 with the grouping breakdown required for any given instance. This works fine!!!!
However what I am trying to do is prevent each sub-report performing major round trips to the underlying cube for each sub-report instance by specifying the filter as part of the MDX query by defining the 7 filter parameters as query parameters. (I could of course not filter the query and place the filter in the report but this would almost certainly lead to performance issues). Instead what I am struggling to do is to create the MDX query in such a way that when a filter is not supplied by the parent, the MDX query does not filter the data.
Can anyone advise on this. I guess my question is more of an MDX question than a reporting services one.

Hello everyone,
I am developing an SSIS solution where the Data Flow task extracts data from a source csv file, then performs several transformations on the source data and then starts inserting the cleansed data into several destination tables.
The Data Flow task is getting too large!
Question:
Is there a way (best practice) for grouping components in the Data Flow - similar to the Container concept in the Control Flow?
I know this question sounds too luxurious, but I really loose the overall picture, when the Data Flow canvas gets too crowded.
Thank you in advance.

I have a table with couple of hundred thousand records, i have added a new column to the table named MD_Group.
Now i need this column populated, so that every 10,000 row set in that table gets a numeric (incremental number) assigned starting from 1.
So the first 10,000 rows will have MD_Group = 1, next 10,000 rows will have MD_Group = 2 , next 10K MD_Group = 3 etc.
For testing purpose here is a results table with total of 11 rows where we want data grouped every 3 rows.
MD_Group
CustomerNumber
AmountBilled
1
12
15243
1
1231234
15243
[code]....
-- Create Sample Table
Declare @GroupRelation_Test TABLE (
MD_Group [varchar](20),
CustomerNumber [varchar](20) ,
AmountBilled [varchar](20) ,
[code]....
-- Test data
INSERT INTO @GroupRelation_Test
( CustomerNumber, AmountBilled,MinAmounttBilled)
SELECT'12','15243','' UNION ALL
SELECT'1231234','15243','' UNION ALL
SELECT'463','15243','' UNION ALL
SELECT'442','15243','' UNION ALL
[code]....

For each of the items I am summing, all I have is a datetime of when the event happened. This is a relational database (not a cube), so I am struggling with how to create the 'buckets' based on period. I think the best way is to dynamically create the buckets based on a given date. Is there a way in RS that it can do this bucketing for you?
Thanks, Mike
