You know how it is, a request for a change or enhancement comes in, that requires some new tables. Do this 5 or 6 times and you spot a better way of doing it so decide to change the schema, then your old data is screwed to you have to write a monster migration!!

I now find I have quite a few "attribute" tables in my schemas. Customer now wants 2nd mobile - add a phone attribute linked to the customer table.
I have one app that is ALL attributes, it tends to get nasty when trying to retrieve data, monstrous number of joins. Which goes to prove you can go too far down that path.

Hello,
I write a query (combine of 2 queries using UNION):
query1
UNION
query2
I want the result of query 2 (there is only one result in query2) will be placed in the last row of the results of the big query.
I mean the results of query1 will be in the first rows and the result of the query2 will be in the last row.
How can i do it?
|
|
|
|
|
Example
select * from table1 <br />
union<br />
select * from table2

OK,
I know that.
But the problem is that the results are mixed.
I want the results of the second query will be the last (in the last rows of the result big table)
|
|
|
|
|
Remember that SQL unions are based on set theory, so if value A is from table 1 and value A is also from table 2 you would only get one value A is your result set. By introducing the sort indicator that "Ashfield" suggests, you would get 2 values of A.
You would get 1,A and 2,A.
I'm not sure if this would impact your algorithm, but I just wanted to make you aware of it.
Cheers,
David

The easiest way I know of is to introduce a sorting column
select '1' as seq,* from table1
union
select '2' as seq from table2
order by seq

Good Day All
I have SQL 200 and a SQL 2008 in one Machine. At First there was SQL 2000 and i install SQL 2008. Now we have a ilog Application written in C++. am not sure what that developer uses to connect to the SQL. Now the Application can connect to SQL 2000 but not to SQL 2008.
I had a thought that the Default instance still points to SQL 2000
I dont know what is wrong
Thanks

Yes... If you have already installed SQL server 2000, the default instance will be held by it. You can only install 2008 as Named instance(Only if you dont configure it to uninstall 2000 default instance).
I think it points to the default instance, can you check the connectionstring of the application to trace how they are connecting.

Thank you , The Problem was not on the SQL side. we have a C++ App and the Developer is developing in his way and i think the Connection string is hard coded and that is a bad idea. but the problem is now resolved. i had to check the registry to resolve it.
Thanks

All,
I have been reading and trying diffrent ways to get this to work but the gist is I am trying to create a temp table that is slecting cloumns from multiple tables
I cant see how a join would work and I have tried pass the columns from table2 as a varible..no luck
The goal is to create one big table I can export off to a file
I am using SQL 2008 Ent.
Here is what I have:
BEGIN
If NOT Exists(Select * from tempdb..sysobjects Where id = object_id('tempdb.dbo.#temp'))
SELECT firstname,lastname, INTO #TEMP FROM Table1
Select email, username into #temp from Table2
END

Hulicat

I needed to use a cross join....

Ok, if anyone knows anything about the subject please help.
Here's the setup: I have written a dll using vs 2005 that reads data from an excel file. It works fine when I reference the dll in my windows app...but when I create the assembly/function combo in SQL I get an OleDB Unspecified error. The weird thing is that it was working on Monday, then when I came back in on Tuesday the server gave me weird errors and now the conn.Open throws an exception I cannot figure it out: (Thanks in advance for any help!)
Here is the error when I try to call the Function in SQL
Declare @a int
set @a = (Select dbo.ExcelTester())
A .NET Framework error occurred during execution of user-defined routine or aggregate "ExcelTester":
System.Data.OleDb.OleDbException: Unspecified error
System.Data.OleDb.OleDbException:

Here are the errors that happened on the server Tuesday:
AppDomain 122 (KWCDB_WBU.dbo[runtime].121) is marked for unload due to common language runtime (CLR) or security data definition language (DDL) operations.
and
AppDomain 130 (KWCDB_WBU.dbo[runtime].129) is marked for unload due to memory pressure.
and
AppDomain KWCDB_WBU.dbo[ddl].131 was unloaded by escalation policy to ensure the consistency of your application. Out of memory happened while accessing a critical resource.

Thank you for your reply Abhishek...I will post some code shortly (I have to log in to work as I'm at home now). Basically the ExcelTester (at this point) just creates an OleDB Connection to an excel file and attempts to open it. This is not my first CLR function integration project and I had the program working almost perfectly by Monday afternoon. Then I came in on Tuesday and started cleaning up some comments, re built the project and once again attempted to create the assemblies. It was at this time I began receiving the errors listed in my post and basically I spent all week trying to make it work again. It would probably be much easier to figure out if OleDB was not returning Unspecified Error when I catch the exception. The whole thing is weird and I'm sure it is something simple that I am just overlooking.
Basically, the function just returns a string "Success" if it works and "Failure" if it doesn't (or an Integer 0 if it works and -1 if not..I've tried many variations). It is breaking on the conn.Open and I feel pretty certain the connection string is okay. If I remove the .Open call the function works perfectly and I'm able to create the assemblies and function and call it with no problem.

Abhishek,
Here is the class I am using (along with my AssemblyInfo file). The only section at this point I am worrying about is the ExcelTester...I had the chgCardRead working by calling it in SQL on Monday, but again, something has gone wrong and I'm at a loss. Also, I am creating the assemblies as Unsafe already. Like I said before, it worked just fine and then just stopped and I have no idea why. Thank you for your assistance.

I have been guided to put my question to this forum.
I am using vb express and MsAccess as database.
I am trying to write a query for the calculation of Stock.
My tables are as under:
PId PDate ItemId Description Price Quantity Amount
1 28/8/2009 1 Coca Cola Normal 1,00 10 10,00
2 28/8/2009 2 Coca Cola Zero 1,00 5 5,00
3 29/8/2009 1 Coca Cola Normal 1,00 5 5,00
4 29/8/2009 2 Coca Cola Zero 1,00 10 10,00
Data in Sales Table is as under:
SId SDate ItemId Description Price Quantity Amount
1 30/8/2009 1 Coca Cola Normal 2,70 2 5,40
2 30/8/2009 2 Coca Cola Zero 2,70 3 7,10
3 31/8/2009 1 Coca Cola Normal 2,70 1 2,70
4 31/8/2009 2 Coca Cola Zero 2,70 2 2,70
I tried something like this to have balance of stock at any date or interval between two dates
Dim cmdText As String = "SELECT pt.ItemId, pt.Description, SUM(pt.Quantity)AS QuantityPurchased, SUM(st.Quantity) AS QuantitySold, (SUM(pt.Quantity) - SUM(st.Quantity)) AS Balance FROM PurchaseTable pt INNER JOIN SalesTable st ON pt.ItemId=st.ItemId WHERE pt.PDate Between @START and @END GROUP BY pt.ItemId, pt.Description"
If con.State = ConnectionState.Closed Then con.Open()
Dim cmd As OleDb.OleDbCommand = New OleDb.OleDbCommand(cmdText, con)
cmd.CommandType = CommandType.Text
cmd.Parameters.AddWithValue("@START", OleDb.OleDbType.Date).Value = TextBox1.Text
cmd.Parameters.AddWithValue("@END", OleDb.OleDbType.Date).Value = TextBox2.Text
Dim dr As OleDb.OleDbDataReader
If con.State = ConnectionState.Closed Then con.Open()
dr = cmd.ExecuteReader
If Not dr.HasRows Then
MessageBox.Show("No Records Found for Date: " & TextBox1.Text)
Else
MessageBox.Show("Record found for Date: " & TextBox1.Text)
ListView1.Items.Clear()
ListView1.ForeColor = Color.DarkRed
ListView1.GridLines = True
While dr.Read
Dim ls As New ListViewItem(dr.Item("ItemId").ToString())
ls.SubItems.Add(dr.Item("Description").ToString())
ls.SubItems.Add(dr.Item("QuantityPurchased").ToStr ing())
ls.SubItems.Add(dr.Item("QuantitySold").ToString() )
ls.SubItems.Add(dr.Item("Balance").ToString())
ListView1.Items.Add(ls)
End While
End If
But i could not get the desired results. Please advise what i am doing wrong with this.
Thanks

The first thing that I notice from your query is that you are using an inner join. This will only return information for items that have an entry in both the Purchase table and the Sales table. If you have any items that are only in one table (e.g a Purchase but no Sale for the same item), they will not show up in your results.
The second thing I notice is that you are selecting on the basis of the date in the Purchase table, but you are ignoring the date in the Sales table. So, you will pick up a subset of the Purchase data but all of the Sales data, which seems a bit wrong to me.
When you say that you are not getting the desired results, what exactly is going wrong? That would help us to narrow down the problem.

The problem i am having is as under:
Data in PurchaseTable
PId PDate ItemId Description Price Quantity Amount
1 28/8/2009 1 Coca Cola Normal 1,00 10 10,00
2 28/8/2009 2 Coca Cola Zero 1,00 5 5,00
3 29/8/2009 1 Coca Cola Normal 1,00 5 5,00
4 29/8/2009 2 Coca Cola Zero 1,00 10 10,00
Data in Sales Table is as under:
SId SDate ItemId Description Price Quantity Amount
1 30/8/2009 1 Coca Cola Normal 2,70 2 5,40
2 30/8/2009 2 Coca Cola Zero 2,70 3 7,10
3 31/8/2009 1 Coca Cola Normal 2,70 1 2,70
4 31/8/2009 2 Coca Cola Zero 2,70 2 2,70
The result of query with date range of 28-08-2009 to 29-08-2009 and also with the date range of 28-08-2009 to 31-08-2009 is displayed as under:
Coca Cola Normal 30 6 24
Coca Cola Zero 30 10 20
whereas actually for date range of 28-08-2009 to 29-08-2009 the result should be as under:
Coca Cola Normal 15 0 15
Coca Cola Zero 15 0 15
And with the date range of 28-08-2009 to 31-08-2009 the result should be as under:
Coca Cola Normal 15 3 12
Coca Cola Zero 15 5 10
Pleae advise what i am doing wrong with the query.
Thanks again for your guidance.

I have already told you what the problem is. Re-read my previous post. You are not including the date on the Sales table in your query.

I saw that this class (easy_odbc) have serious memory leak. I try to insert one record every second, it makes the increase of memory without limit(every insert deals memory about 500kb). It seems that no frees statament memory, how can i resolve this problem?
At moment i close and open continuously the database, but in my opinion this isn't best solution.
thank you

I'm apologize...
Easy_ODBC class : EasyODBC[^]
this is my code(m_pDbM is valid pointer to open database):
m_pDbM.Close();
m_pDbM.Open("nChart","","");
CString query;
query.Format("INSERT INTO %s (%s... (continue)");
m_pDbM.Execute(query);
