How To Join Two Tables By Select Command?
Apr 11, 2008
Hi
I have a tables like below
TblA
ID(unique)---SessionID(unique)----Ref
TblB
VisitID(unique)---SessionID(Multiple)----Page--Pdcode
My question : How Do I bring all rows from TblB and matching single row from TblA (I have more than one sessionID in TblB and only one Unique SessionID in TblA).
The Select query I was using is
SELECT PageViews.ID AS ID, PageDetailView.VisitID, PageViews.PageAccessed, PageDetailView.PageAccessed AS Expr1, PageViews.QueryString,
PageDetailView.QueryString AS Expr2, PageViews.Referer, PageViews.SessionID, PageDetailView.SessionID AS Expr3, PageDetailView.PdtID,
PageDetailView.Pcode, PageDetailView.CustID, PageDetailView.OrdTot, PageViews.[Date]
FROM PageViews RIGHT OUTER JOIN
PageDetailView ON PageViews.SessionID = PageDetailView.SessionID
ORDER BY PageViews.ID DESC

Why would I use a left join instead of a inner join when the columns entered within the SELECT command determine what is displayed from the query results?

In my new job I have to administer an existing SQL-database with approx. 50 tables. In this database are no joins :confused: defined between the tables. We use a Visual Basic 6 application to create a GUI and within this VB6 app. there are several SELECT statements to retrieve the required data. In these SELECT statements are all the INNER and OUTER JOINS between the tables defined.
My question: is this a correct way to work with or is it better to create all the JOINs between the tables on the database itself? Or should I create different views and define the JOINs in there? My main concern is the speed to retrieve data and second the required time to administer this database.

I have got the following union statement:
SELECT plan2008.jahr, plan2008.monat, plan2008.kdkrbez, plan2008.kdgrbez, plan2008.abgrbez, plan2008.artnr,
FROM plan2008
GROUP BY plan2008.jahr, plan2008.monat, plan2008.kdkrbez, plan2008.kdgrbez, plan2008.abgrbez, plan2008.artnr
UNION
SELECT fsp_auftrag.jahr, fsp_auftrag.monatnr, fsp_auftrag.kundenkreis, fsp_auftrag.kundengruppe, fsp_auftrag.abnehmergruppe, fsp_auftrag.artnr
FROM fsp_auftrag
GROUP BY fsp_auftrag.jahr, fsp_auftrag.monatnr, fsp_auftrag.kundenkreis, fsp_auftrag.kundengruppe, fsp_auftrag.abnehmergruppe, fsp_auftrag.artnr
My problem is that each table contains additional values like art_amount, art_turnover etc... whereby the first table contains plan values while the second table contains actual values.
My goal is to get plan as well as the actual values in one row, how is that possible? If I put the values into each of the selects I get two rows, which is not the wished output.
Is it possible to join the tables after the union took place?
Thanks in advance!

Hi guys,
I'll appreciate any help with the following problem:
I need to retrieve data from 3 tables. 2 master tables and 1 transaction table.
1. Master table TBLOC contain 2 records :
rcd 1. S01
rcd 2. S02
2. Master table TBCODE contain 5 records:
rcd 1. C1
rcd 2. C2
rcd 3. C3
rcd 4. C4
rcd 5. C5
3. Transaction table TBITEM contain 4 records which link to 2 master table:
rcd 1. S01, C1, CAR
rcd 2. S01, C4, TOY
rcd 3. S01, C5, KEY
rcd 4. S02, C2, CAR
I use Left Join & Right Join to retrieve result below (using non-ASNI method) but it doesn't work.
Right Join method:
SELECT C.LOC, B.CODE, A.ITEM FROM TBITEM A RIGHT JOIN TBCODE B ON A.CODE = B.CODE
RIGHT JOIN TBLOC C ON A.LOC = C.LOC
GROUP BY C.LOC, B.CODE, A.ITEM ORDER BY C.LOC, B.CODE
When I use Non-ASNI method it work:
SELECT C.LOC, B.CODE, A.ITEM FROM TBITEM A, TBCODE B, TBLOC C
WHERE A.CODE =* B.CODE AND A.LOC =* C.LOC
GROUP BY C.LOC, B.CODE, A.ITEM ORDER BY C.LOC, B.CODE
Result:
LOC CODE ITEM
-----------------------------
S01 C1 NULL
S01 C2 NULL
S01 C3 CAR
S01 C4 TOY
S01 C5 KEY
S02 C1 NULL
S02 C2 CAR
S02 C3 NULL
S02 C4 NULL
S02 C5 NULL
Please Help.

Hello,
I have only started VBS and SQL a week ago so..
The scenario is that I have 1 SQL db and 3 tables as follows:
tblSAVDetails (columns SERVERS : SAVGroup : SAVParent)
tblSAVComputers (Columns SERVERS)
tblSAVResults (Columns SERVERS : SAVGroup : SAVParent)
The tblSAVDetails has raw data from all of our servers nationwide
The tblSAVComputers have a list of servers in our site
The SAVResults will store the results of the query
I want compare the list of servers in tblSAVComputers with the list contained in tblSAVDetails and IF it finds the server to then retrieve the details. However if it doesn't find the server I want to flag it (with a NULL or NA or somthing). After all that I want it to insert the results into tblSAVResults.
The SQL command I am using is:
---------
SELECT *
FROM tblSAVComputers LEFT OUTER JOIN
tblSAVDetails ON tblSAVComputers.SAVComputers = tblSAVDetails.SERVERS
---------
I have tried so many ways, but I just cant get it to work. I know how to insert data into a DB, but I just cant get this command to work in vbScript (it works fine if I run it directly on the SQL server)
Any help would be brilliant! If you need more info, please let me know.
Thanks

The select command below will output one patient’s information in 1 row:
Patient id
Last name
First name
Address 1
OP Coverage Plan 1
OP Policy # 1
OP Coverage Plan 2
[code]...
This works great if there is at least one OP coverage. There are 3 tables in which to get information which are the patient table, the coverage table, and the coverage history table. The coverage table links to the patient table via pat_id and it tells me the patient's coverage plan and in which priority to bill. The coverage history table links to the patient and coverage table via patient id and coverage plan and it gives me the effective date.
select src.pat_id, lname, fname, addr1,
max(case when rn = 1 then src.coverage_plan_ end) as OP_Coverage1,
max(case when rn = 1 then src.policy_id end) as OP_Policy1,
code]...

I'm using the following Select Command:SELECT MAX(Document) AS DOC FROM dbo.Communicator WHERE (ReleaseDate <= { fn NOW() })It shows the most current date in the ReleaseDate column - even if the date is in the future. I don't want it to show future dates. If I change the command to WHERE (ReleaseDate >= { fn NOW() }) it doesn't work at all. I only want it to return one row - the latest releases date that is equal to or less than now.Any ideas?

I have a web form that has textbox1, textbox2 and DropDownList1. Let’s say textbox one is first name, textbox2 is last name and dropdownlist1 is age. How do I write a query that will select from database table dbo.emoployee where last name = dbo.employee.lastname and all other fields are blank, I want it to return all employees with that last name. If someone types in the last name and selects the age from the drop down list then I want to return all employees where last name = dbo.employee.lastname and age = dbo.employee.age. If someone types in just the first name then I want to return all employees where first name = pub.employees.firstname? I have been trying to do this using the SQLDatasource but cannot seem to figure it out.

I currently have a webpage that allows visitors to post links to their own website. As a spam filter I want to create a scheduled task that selects repeat entries in the database under the column name domain. I already made a filter to take everything out of the link the provide and leave it with just the domain name. I tested it and it works. Now I need a SQL command to select all the rows with repeats of the domain. Look at the following table example to better understand what I mean uid x y domain1 100 110 www.spam.com2 100 120 www.spam.com3 110 130 www.homepage.com4 210 220 www.myaspspam.com5 510 560 www.myaspspam.com in this example I would like 1 and 2 to be selected as well as 4 and 5 into a dataadapter so that I can delete them accordingly.

I have a SqlDataSource object that is bound to a GridView control. I have configured the SqlDataSource with a default select command. Under certain values of query strings on the URL for this page (Default.aspx), I want to change the select command. So I put the statements in the Page_Load method for Default.aspx to define SqlDataSource1.SelectCommand. The changed SelectCommand works fine for the first page of GridView data and shows 5 GridView pages, but if I switch to one of the other pages, it seems to revert to the default SelectCommand (which generates 19 GridView pages). I assume I should put my code to change the SelectCommand somewhere else. Can someone help me with where to put it? Thanks!

Hi,
I'm trying to use a CheckBoxList to display certain records in a Grid View. I have a Grid View, a CheckBoxList with four items and a SqlDataSource and when the user check or uncheck one or more items in the CheckBoxList the Grid View should show records accordingly. I’ve tried to make it work but it’s only the first checked item in the Grid View that has any effect. I use VB. Thanks

Hi Guys,
I'm fairly new to .Net and have reached a point in the coding I can't seem to get past.
I've created a table with Visual Studio 2005 and MySQL Server 2008 (Beta) and am trying to make the "Select" button bind a result from that table (in this case, image_id) then open up that image ID in a Image details page, I've created the table in Visual Studio 2005.
Here's what I've got so far;
Page 1Protected Sub GridView1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs)Dim row As GridViewRow = GridView1.SelectedRowSession("session_current") = row.Cells(1).TextServer.Transfer("page2.aspx")End SubI think this page isn't at fault as it reads the parameter into a text box on page2
Page2</asp:GridView><asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString3 %>"ProviderName="<%$ ConnectionStrings:ConnectionString3.ProviderName %>" SelectCommand="SELECT * FROM [profiles] WHERE ([profile_id] LIKE '%' + ? + '%')"><SelectParameters><asp:SessionParameter Name="profile_id" Type="String"/></SelectParameters>
I'd sincerly appreciate any help, any one may be able to offer,
Cheers,
Craig

I need to move various records from a production database to an archive database. The fields in the two databases are identical but the archive database has an additional "Transfer Date" field. Can anyone recommend an easy way to create an SQL statement to move the record from production to archive? I've tried
INSERT INTO ARCHIVE (SELECT * FROM PRODUCTION WHERE ACCOUNTNO='XYZ')
but I get an error saying the columns among the two tables do not match (obviously because of the "Transfer Date" column). Is there a way to use a similar SQL statement that will populate the "Transfer Date" column w/ today's date?
Thanks in advance for your help.

Hi All,
Does anyone know if you can add columns to a local pulled table and if so can you use a select command to push the table back and exclude the added columns.
Basically I need to know if a record has been added on the PDA so I can get an ID from the server before pushing it back. I cannot alter the sql server database because it is part another application.
Cheers,
Jiggy!
