Designing Table to Record Hierarchy - Database Discussion Boards

I've created a stored procedure which retrives a list of worklogs for a specific week, log time is added together, joined to user table based on UserID and then returned as HoursWorked.

This worked fine as the following code:

ALTER procedure [dbo].[GetAllUsersWhoHaventSubmittedTimeForWeek]
(
@MinimumHours float,
@EndDate datetime,
@AmountOfDaysBack int
)
as
begin
SELECT u.Email, u.FirstName + ' ' + u.LastName AS Usersname, round(sum(WorkDone) / 60, 1)
FROM Users u LEFT OUTER JOIN 
(
	select sum(WorkDone) WorkDone, UserId UserId, WorkUnitTypeId WorkUnitTypeId
	FROM worklog
	WHERE WorkLogDateTime >= dateadd(d, -@AmountOfDaysBack, @EndDate) and WorkLogDateTime <= dateadd(d, 1, @EndDate)
	GROUP BY UserID, WorkUnitTypeId
	HAVING round(sum(WorkDone) / 60, 1) < @MinimumHours
) w
ON u.UserId=w.UserId
WHERE u.userid not in (SELECT User_ID FROM ReportUsers WHERE Status = 0) and u.isactive = 1
GROUP BY w.UserId, u.FirstName, u.LastName, u.Email, WorkUnitTypeId
ORDER BY sum(WorkDone) DESC

END

I then realised WorkDone can sometimes store hours, days or weeks and is defined in 'WorkUnitTypeID' so I added a CASE statement to the Select:

ALTER procedure [dbo].[GetAllUsersWhoHaventSubmittedTimeForWeek]
(
@MinimumHours float,
@EndDate datetime,
@AmountOfDaysBack int
)
as
begin
SELECT u.Email, u.FirstName + ' ' + u.LastName AS Usersname,
	CASE w.WorkUnitTypeId
		WHEN 1 THEN ISNULL(round(sum(w.WorkDone / 60),1), 0) --Minutes
		WHEN 2 THEN ISNULL(round(sum(w.WorkDone),1), 0)		 --Hours
		WHEN 3 THEN ISNULL(round(sum(w.WorkDone * 24),1), 0) --Days
		WHEN 4 THEN ISNULL(round(sum(w.WorkDone * 168),1), 0) --Weeks
		ELSE 0
	END WorkDone
FROM Users u LEFT OUTER JOIN 
(
	select sum(WorkDone) WorkDone, UserId UserId, WorkUnitTypeId WorkUnitTypeId
	FROM worklog
	WHERE WorkLogDateTime >= dateadd(d, -@AmountOfDaysBack, @EndDate) and WorkLogDateTime <= dateadd(d, 1, @EndDate)
	GROUP BY UserID, WorkUnitTypeId
	HAVING round(sum(WorkDone) / 60, 1) < @MinimumHours
) w
ON u.UserId=w.UserId
WHERE u.userid not in (SELECT User_ID FROM ReportUsers WHERE Status = 0) and u.isactive = 1
GROUP BY w.UserId, u.FirstName, u.LastName, u.Email, WorkUnitTypeId
ORDER BY sum(WorkDone) DESC

END

Again this worked but presented a new issue, the procedure now returns multiple rows for the same user but for each of the WorkUnitTypeID - instead of adding them together.

I'm new to SQL in general and have that feeling I've missed something really simple! Any feedback would be much appreciated.

Try replacing

GROUP BY w.UserId, u.FirstName, u.LastName, u.Email, WorkUnitTypeId

Group by u.Email, u.FirstName + ' ' + u.LastName,
	CASE w.WorkUnitTypeId
		WHEN 1 THEN ISNULL(round(sum(w.WorkDone / 60),1), 0) --Minutes
		WHEN 2 THEN ISNULL(round(sum(w.WorkDone),1), 0)		 --Hours
		WHEN 3 THEN ISNULL(round(sum(w.WorkDone * 24),1), 0) --Days
		WHEN 4 THEN ISNULL(round(sum(w.WorkDone * 168),1), 0) --Weeks
		ELSE 0
	END

Thanks for the reply but no joy:

Cannot use an aggregate or a subquery in an expression used for the group by list of a GROUP BY clause.

Sorry,

My mistake. Try this group by clause:

Group by u.Email, u.FirstName + ' ' + u.LastName

Can anyone else offer any more on this? Sorry for the spam but it's quite urgent. I've tried playing about with it more by placing the case inside the JOIN - which I got my hopes up about but still the same result of recieving multiple user rows with different worklogs Mad | :mad:

ALTER procedure [dbo].[GetAllUsersWhoHaventSubmittedTimeForWeek]
(
@MinimumHours float,
@EndDate datetime,
@AmountOfDaysBack int
)
as
begin
SELECT	u.Email,
		u.FirstName + ' ' + u.LastName AS Usersname,
		w.WorkDone
from Users u LEFT OUTER JOIN 
	( 
	Select	UserID,
			WorkUnitTypeId,
			CASE WorkUnitTypeId
			WHEN 1 THEN ISNULL(round(sum(WorkDone / 60),1), 0)	--Minutes
			WHEN 2 THEN ISNULL(round(sum(WorkDone),1), 0)		--Hours
			WHEN 3 THEN ISNULL(round(sum(WorkDone * 24),1), 0)	--Days
			WHEN 4 THEN ISNULL(round(sum(WorkDone * 168),1), 0)	--Weeks
			ELSE 0
			END as WorkDone
			FROM worklog
			WHERE WorkLogDateTime >= dateadd(d, -@AmountOfDaysBack, @EndDate) and WorkLogDateTime <= dateadd(d, 1, @EndDate)
			--HAVING round(sum(WorkDone) / 60, 1) < @MinimumHours
			GROUP BY	UserId, 
						WorkUnitTypeId
	) w
ON u.UserId=w.UserId
WHERE u.userid not in (SELECT User_ID FROM ReportUsers WHERE Status = 0) and u.isactive = 1
GROUP BY w.UserId,
			u.FirstName,
			u.LastName,
			u.Email,
			WorkUnitTypeId,
			WorkDone
ORDER BY sum(WorkDone) DESC

Got it working! Bascilly deleted it and started again and managed to get it working from the advice you both gave (Wrapping the case in a sum and removing Workunittypeid from the top level group by).

Thanks for the help - first and last stored procedure I attempt Laugh | :laugh:

Designing Table to Record Hierarchy

vhassan5-Aug-09 0:58

Hi,

How we can design a database tables that record hierarchical data. The levels of hierarchy are not fixed. For example:

Table Header:
A B C D E F G SomeOtherHeader

Respective record:
1 4 3 2 6 t a PK_of_Another_Table
2 3 4 6 8 y a PK_of_Another_Table

Now the record has upto Level "G" with different values. But it can be up to different level for another block of record.

So what is best relational implementation of this Dynamic Hierarchy?
Please refer any link that is worth reading related to this topic.

Thanks.
Good Day.

Hello,

I am developping ASP.NET 2008. My data is stored in SQL server 2008.
The problem is when I query, I got 0 records and this is because the data is stored in hebrew.
I tried to change the collation property in Column of the table but it doesn't help
Please help

Return ""

End Function

The Location field contains hebrew words and when I am querying by changing the database content in english it works perfectly with the same code I post upstair. So I am sure that the problem is because the hebrew. I need to config anywhere that the Location column can contain hebrew characters. Again, I success to insert hebrew words in the databse but when I am querying no records are found

How do you know that is the problem? AFAIK, if table has records, query will return irrespective of the type of data. Are you sure the table has records? What data type are you using for keeping values?

This is a new table that I insert record in it and yes I am sure there are records and i am sure that my query is OK. I just need to know how to config the column that store hebrew characters to get abiility for query on it

Invalid column name error?

Error: saving tester - TST-000-341 - item :: System.Data.SqlClient.SqlException: Invalid column name 'TST'.

update tbl_swbom_checklist_testers set passfail='No' where package=992-700-358 and tester=TST-000-341

That is part of the exception thrown by my web app. There is no column named TST, the column is named TESTER, which is why the SQL statement is 'where tester=TST-000-341'. The PACKAGE column is the same syntax and it has no complaints. What am I missing here? Here is my entire SP:

CREATE PROCEDURE dbo.sp_UpdateTesterColumn 
(
@PACKAGE nvarchar(255),
@TESTER nvarchar(100),
@COLUMN nvarchar(100),
@VALUE nvarchar(100),
@LASTCHANGEBY nvarchar(100)
) 
AS 

declare @sql nvarchar(1024)
set @sql=''

set @sql=@sql+'update tbl_swbom_checklist_testers set '+@COLUMN+'='''+@VALUE+''' '
set @sql=@sql+'where tester='+convert(nvarchar(100),@tester)+' and package='+convert(nvarchar(255),@package)

print @sql

exec sp_executesql @sql
GO

Obviously the print is when I uncomment the print statement. What am I missing here?

Instead using four single quotes then use CHAR(39)

set @sql=@sql+' where tester='+CHAR(39)+convert(nvarchar(100),@tester)+CHAR(39)+'  and package='+CHAR(39)+convert(nvarchar(255),@package)+CHAR(39)

How to edit Dataset value (NOT DATA GRID)

Hi All,

i want to edit DataSet value before binding to GridView. How can i do that..?

conn.open();

string result="select name,address,age";
sqlCommand cmnd=new sqlCommand(result);
sqlDataAdapter ad=new sqlDataAdapter(result,conn);
DataSet ds=new DataSet();
result.Connection=conn;
ad.SelectCommand=result;

// in here i want to edit (divide age value by 2) before bind data to gridview.

ad.fill(ds);
GridView1.DataSource=ds;
GridView1.DataBind();

conn.close();

i want to divide age value by 2 before bind data to gridview.How can i do that...???

Thank you very much .....

A DataSet object is a collection of DataTable objects. You could loop through the table and update the age with something like this:

For Each row As DataRow In ds.Tables(0).Rows<br />
   row("age") = row("age") / 2<br />
Next

Or you could just do it in the select by changing your select statement to this string:
"select name, address, age/2 as age"

Hope this helps.
