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.
i have 2 columns named firstname and lastname, i need to get them into 1 column named name with a space between them. Does anyone have a tip to do this?
Hi,I was trying to retrieve some data in such a way that it 2 columns willbe merged into one, with a column in between. I am trying to dosomething like this:SELECT LastName + ", " + FirstName AS NameFROM EmployeeTBLORDER BY LastNameBut SQL Server does not like this syntax (though it does work with"LastName + FirstName").I appreciate any help.Thanks,Aaron
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 :
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..

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);

Hi,I have the following SQLSELECT Table1.Col1, Table3.Col1 AS Expr1,COUNT(Table1.Col2) AS Col2_No, COUNT(Table1.Col3) AS Col3_No etc,FROM Table3INNER JOIN Table2 ON Table3.Col1=Table2.Col1RIGHT OUTER JOIN Table1 ON Table2.Col2=Table2.Col2GROUP BY Table1.Col1, Table3.Col1The output rows have a value in either Table1.Col1 or Table3.Col1 but notboth.I'd like to combine Table1.Col1 and Table3.Col1 and group by the combinedcolumn in the result but don't know how.Thanks gratefully
I am retrieving some data from Invoices, Customers and Companies tables as follows, but would like to make the customerName and the Companies.Name as single column such Name and similarly for customerID/companyID and customerCode/companyCode.
Code: with cte as ( selectdistinct i.invoiceNumber, itemID, customers.customerID, Companies.companyID ,SUM(net_weight) as totalWeight, rate ,(select SUM(net_weight) * rate) as amount
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.
The goal is to group all this transactions by Month and Year.
Something like this....
MS030_A MS030_F MS036_A MS036_F MS040_A MS040_F Month Year
3 2 2 2 2 2 1 2006
4 4 7 9 8 9 2 2006
10 10 6 8 8
3 2006
4 4 5 5 3 2 4 2006
5 6 8 3 7 1 5 2006 For just one date column it is pretty straight forward i.e., just do a select count and group by DATEPART ( Mm, DateField) but for multiple columns i am in a total fix....
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
If i go for Group by clause (SQL) then I can group them by week but cant display the individual rows. Is there any way to do this (better if in a single query)
some one plz help me. I had a table with these columns. Table(Id int,Name varchar,Value Varchar). I have to group them by ID and each Name becomes column name of the new table
ex:- Id Name Value -------------------- 1 x a1 2 x a2 3 x a3 1 y b1 2 y b2 3 y b3 1 z c1 2 z c2 3 z c3
I need it in this way
x y z ------------ a1 b1 c1 a2 b2 c2 a3 b3 c3
(no of columns in the new table can't be pre determined)
and which one would be better option to do this in VB.Net code or in a Storedprocedure?
I have a simple question, but I can't seem to get around it. Please help.
I have a table like this: [select * from Enrollment] Course ID PersonID Role BCC110 123 Student BCC110 321 Student BCC110 456 teacher BCC123 457 Student
and I want to have a report like
Course ID Total Students Total Teachers BCC110 2 1 BCC123 1 0
I want to group data in matrix column. Lets say i have a field say Weekday which has weekdays from monday to friday. then suppose i have measure "my expenditure".
I will place Weekdays in column field of matrix and "my expenditure" in data field". lets not worry about rows.
Now i want something like this.
Group my expenditure in three categories like
1. My expenditure on monday
2. My expenditure on tuesday
3. My expenditure on days other than monday and tuesday.(means it should show me data for wednesday,thursday,friday and also if no weekday is entered)
what I am doing now is i m writting IIF expression in the column field but with that i get data for monday and tuesday but data for all the other days is not getting clubbed.
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 END
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:
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.
I am trying to create a group on this data example
RecordNo, Item, Date,NULL 1, ABBB, NULL, 0 << first group 2, ABBB, 01-06-2011,NULL << first group 3, ABBB,NULL,NULL << 2nd group 4, ABBB, 02-01-2011,NULL << 2nd group 5,CAAA,NULL,NULL << 1st group 6,CAAA,NULL,NULL << 1st group 7,CAAA,01-01-2010,NULL << 1st group 8,CAAA,01-01-2011,NULL << 2nd group 9,CAAA,01-05-2012, NULL << 3rd group
Basically 3 groups on date, by item, so for each date change/ per part the group increments been playing with row_number partitions, but cant seem to get what i need.
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.
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
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.
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.
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.
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.
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

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?
