Return NULL Values In SELECT Statement With INNER JOIN ?
May 16, 2005
If I try to run the code below, and even one of the values in the INNER
JOIN statements is NULL, the DataReader ends up with zero rows.
What I need is to see the results even if one or more of INNER JOIN
statements has a NULL value. For example, if I want info on
asset# 2104, and there's no value in the DriverID field, I need the
rest of the data to display and just have the lblDriverName by
blank. Is that possible?
<code>
Sub BindSearchGrid()
Dim searchUnitID As String
Dim searchQuery As String
searchUnitID = tbSearchUnitID.Text
lblIDNum.Text = searchUnitID
searchQuery = "SELECT * FROM Assets " & _
"INNER JOIN Condition ON Condition.ConditionID = Assets.ConditionID " & _
"INNER JOIN Drivers ON Drivers.DriverID = Assets.DriverID " & _
"INNER JOIN Departments ON Departments.DepartmentID = Assets.DepartmentID " & _
"INNER JOIN AssetCategories
ON AssetCategories.AssetCategoryID = Assets.AssetCategoryID " & _
"INNER JOIN Store ON
Store.[Store ID] = Assets.StoreID WHERE RTRIM(Assets.[Unit ID]) = '"
& searchUnitID & "'"

I have table Products and Orders that has the following columns:
table Products: ProductID, ProductName
table Orders: OrderID, ProductID, OrderDate, Quantity, Price
The Orders table contains orders placed on all the dates. I want to obtain a list of orders for a particular date, if there is no order for a product on the requested date, I want to return null values for the Quantity and Price fields.
I tried the following select statement:
select Products.ProductName, Orders.Quantity, Orders.Price from Products left join Orders on Products.ProductID = Orders.ProductID where Orders.OrderDate = '10/16/2004'
Where, there are a total of three products (A,B,C) in table Products. Product-C has no order on 10/16/2004, but I want it to return :
ProductName / Quantity / Price
Product-A 5 1.89
Product-B 6 2.43
Product-C null null
Obviously, my sql statement won't work becaue the where clause will filter out Product-C.
Could anyone help me figure out how to modify my sql code to get the resultset I want?
Thanks in advance.

Hello,
I have this INNER JOIN that is fine to show all possible combinations. But I need to show only rows that have one or more Null values in tbIntersect.
Should I use nested LEFT JOINT? How?
This is the SQL statement:
sSQL = "SELECT DISTINCT tbCar100.Car100_ID, tbCar100.Description100 AS [Caractéristique 100], " & _
"tbCar200.Car200_ID, tbCar200.Description200 AS [Caractéristique 200], " & _
"tbCar300.Car300_ID, tbCar300.Description300 AS [Caractéristique 300], " & _
"tbCar400.Car400_ID, tbCar400.Description400 AS [Caractéristique 400], " & _
"tbCar500.Car500_ID, tbCar500.Description500 AS [Caractéristique 500], " & _
"tbCar600.Car600_ID, tbCar600.Description600 AS [Caractéristique 600], " & _
"tbCar700.Car700_ID, tbCar700.Description700 AS [Caractéristique 700], " & _
"tbProducts.Prod_ID, tbProducts.PartNumber AS [Part Number] , tbProducts.Description AS [Description] , tbProducts.DateAdded AS [Date] " & _
"FROM tbProducts INNER JOIN (tbCar700 INNER JOIN (tbCar600 INNER JOIN (tbCar500 INNER JOIN (tbCar400 INNER JOIN (tbCar300 INNER JOIN (tbCar100 INNER JOIN " & _
"(tbCar200 INNER JOIN tbIntersect ON tbCar200.Car200_ID = tbIntersect.Car200_ID) " & _
"ON tbCar100.Car100_ID = tbIntersect.Car100_ID) ON tbCar300.Car300_ID = tbIntersect.Car300_ID) ON tbCar400.Car400_ID = tbIntersect.Car400_ID) ON tbCar500.Car500_ID = tbIntersect.Car500_ID) ON tbCar600.Car600_ID = tbIntersect.Car600_ID) ON tbCar700.Car700_ID = tbIntersect.Car700_ID) ON tbProducts.Prod_ID = tbIntersect.Prod_ID " & _
";"
Here is the content of the tbIntersect table:
Car100_ID Car200_ID Car300_ID Car400_ID Car500_ID Car600_ID Car700_ID Prod_ID ID
1 1 1 1 1 1 1 1 1
1 2 1 1 1 1 1 19
1 3 1 1 1 1 1 20
I need to return the rows that have null data, ex: second row because Prod_ID is NULL and third row because Car300_ID is NULL. In fact I need the data from the other joint tables that correspond to these ID fields.
Thanks

Ok I have a query "SELECT ColumnNames FROM tbl1" let's say the values returned are "age,sex,race".
Now I want to be able to create an "update" statement like "UPATE tbl2 SET Col2 = age + sex + race" dynamically and execute this UPDATE statement. So, if the next select statement returns "age, sex, race, gender" then the script should create "UPDATE tbl2 SET Col2 = age + sex + race + gender" and execute it.

Hello all,
I have been working with a DetailsView control for the past week and it is a great control, but also lacks on some departments. Anyhow I need to know what the best approach for this scenerio would be?
I have a SqlDataSource"
<asp:SqlDataSource ID="SqlUpsertAffiliateDetails" runat="server" ConnectionString="<%$ ConnectionStrings:connectionstring %>"
SelectCommand="SELECT am.affiliate_id AS AffiliateId, am.member_id AS MemberId, m.First_Name, m.Last_Name, am.category_id AS CategoryId, ac.category_name, am.profile_web_address AS WebAddress, am.profile_email_1 AS Email, am.comments AS Comments, am.date_modified FROM tAffiliateMaster AS am WITH (NOLOCK) INNER JOIN tAffiliateCategories AS ac WITH (NOLOCK) ON am.category_id = ac.category_id INNER JOIN rapdata..Member AS m WITH (NOLOCK) ON am.member_id = m.Member_Number WHERE (am.affiliate_id = @AffiliateId)"

<SelectParameters>
<asp:QueryStringParameter Name="AffiliateId" QueryStringField="affiliate_id" />
</SelectParameters>
<UpdateParameters>
<asp:Parameter Name="Action" Type="Byte" DefaultValue="2" />
</UpdateParameters>
</asp:SqlDataSource>
And my SP:/* 09-19-07 Used to update affiliate profile */
CREATE PROCEDURE spUpsertAffiliateProfile
@Action tinyint,
@AffiliateId int,
@MemberId int = -1,
@CategoryId int,
@WebAddress varchar(50),
@Email varchar(50),
@Comments varchar(1500)
AS
SET NOCOUNT ON
-- Find errors first, check is not needed if deleting
IF @Action <> 3
IF NOT EXISTS (SELECT Member_Number FROM rapdata..Member_Association WHERE Member_Number = @MemberId AND Status = 'A' AND Association_ID = 'TRI' AND Bill_Type_Code LIKE '%AF%')
BEGIN
SELECT retval = 'A qualified member ID was NOT found. Action Failed.', errorcount = 1, 0 AS affiliate_id
RETURN
END
IF @Action = 1
IF EXISTS (SELECT member_id FROM tAffiliateMaster WHERE member_id = @MemberId)
BEGIN
SELECT retval = 'This member has already been listed. Action Failed.', errorcount = 1, 0 AS affiliate_id
RETURN
END
IF @Action = 1 AND @AffiliateId = 0-- insert
BEGIN
INSERT INTO tAffiliateMaster
(member_id, category_id, profile_web_address, profile_email_1, comments)
VALUES
(@MemberId, @CategoryId, @WebAddress, @Email, @Comments)
SELECT retval = 'Record Entered', errorcount = 0, @@IDENTITY AS affiliate_id
RETURN
END
ELSE IF @Action = 2 AND @AffiliateId > 0-- update
BEGIN
UPDATE
tAffiliateMaster
SET
category_id= @CategoryId,
profile_web_address=@WebAddress,
profile_email_1=@Email,

affiliate_id = @AffiliateId AND member_id = @MemberId

RETURN
END
ELSE IF @Action = 3 AND @AffiliateId > 0-- delete
BEGIN
DELETE
tAffiliateMaster
WHERE
affiliate_id = @AffiliateId
SELECT retval = 'Record Deleted', errorcount = 0, 0 AS affiliate_id
RETURN
END
GO
My question is how will I be able to return the retval? Will I need to do it within the code behind of the SqlDataSource Updated Event?
Thanks!

Hey guys,
This is what I think and hope is a fairly straight forward SQL question
Essentially, I have a table which has the following columns that are relevent to my question:
PROJID
ACTIVITY_NAME
COMPLETION_DATE
Rows in this table are, for example:
PROJID ACTIVITY_NAME COMPLETION_DATE
1 Prepro 10/12/2007 3:42:30
2 Prepro 10/13/2007 9:16:27
2 QA 10/13/2007 10:00:01
2 Delivery 10/14/2007 09:31:12
etc.
So, really the key is the PROJID & the ACTIVITY_NAME (really, there's a unique column ID, but for this question, I'll leave it at that).
(Though this should be much easier to accomplish in code, the system is not built that way so) Is there a good way that I could return a status for a given PROJID based on whether a row exists for a given PROJID). In other words, ultimately, I would like to return something like this:
PROJID LAST_ACTIVITY
----------------------------------------------
1 Prepro
2 Delivery
where the activity order (in this case) is Prepro, QA, Delivery. So because a Delivery row exists for PROJID 2, then the LAST_ACTIVITY would return "Delivery" and because only Prepro exists for PROJID 1, the LAST_ACTIVITY returned would be Prepro
I really appreciate the help
Thanks,
Steve

I have a stored procedure that selects the unique Name of an item from one table.
SELECT DISTINCT ChainName from Chains
For each ChainName, there exists 0 or more StoreNames in the Stores. I want to return the result of this select as the second field in each row of the result set.
SELECT DISTINCT StoreName FROM Stores WHERE Stores.ChainName = ChainName
Each row of the result set returned by the stored procedure would contain:
ChainName, Array of StoreNames (or comma separated strings or whatever)
How can I code a stored procedure to do this?

I am trying to return all the names of employees and their managers
this query returns all the employees except for 1
SELECT E.FNAME,E.LNAME,M.FNAME,M.LNAME
FROM EMPLOYEE E,EMPLOYEE M
WHERE E.SUPERSSN=M.SSN
the one that isn't returned has a null SUPERSSN, but when I add in:
OR E.SUPERSSN IS NULL
it returns a row with the name of the employee whose SUPERSSN is null 8 times (where each time the M.FNAME,M.LNAME are other employee names)
How do I ammend the first query to return each employee and their respective manager once, the employee without a manager having null values for the manager name columns?

Hi All,
I need a bit of help with a join. I have 2 tables :
TradeSummary
has fields : SymbolID, CurrentPrice, TotalValue
Trades
has fields : SymbolID, TradeID, ExecutionTime, TradeValue
TradeSummary has one entry for each SymbolID, while Trades contains one or more entries per SymbolID
and what I want to retreive is :
For every item in TradeSummary get CurrentPrice, TotalValue from TradeSummary
and also get TradeValue from Trades for the record for max(ExecutionTime)
tables are joined on TradeSummary.SymbolID = Trades.SymbolID
Every attempt of mine so far returns multiple rows for each SymbolID - I want only one row per SymbolID
thanks in advance

I have two tables:
1. tblProducts
columns: ProductID, ProductName
2. tblProductCodes
columns: ProductID, CustomerID, ProductCode
The 2nd table is for storing product codes for customers, in other words, one product can have different ProductCode for different customers. But some customers do not have ProductCode for a ProductID.
I want to create a query to return all the Products and its ProductCode (null is valid) for a specific customer.
I tried:
SELECT dbo.tblProductCodes.ProductCode, dbo.tblProductCodes.CustomerID,
dbo.tblProducts.ProductName,
dbo.tblProducts.ProductID
FROM dbo.tblProducts LEFT OUTER JOIN
dbo.tblProductCodes ON dbo.tblProducts.ProductID = dbo.tblProductCodes.ProductID
WHERE dbo.tblProductCodes.CustomerID = 2
But the query left out all products that does not have ProductCode value in tblProductCodes table for CustomerID = 2. I want all the ProductName returned from query and render null or empty string for ProductCode value if the code does not exist in tblProductCodes table for the customer.
Any help is highly appreciated.

I have tables and a function as representated by the code below. The names for objects here are just for representation and not the actual names of objects. Table RDTEST may have one or multiple values for RD for each PID. So the function GIVERD will return one or multiple values of RD for each value of PID passed to it.
When I run the following query, I get the required result except the rows for CID 500 for which PID is NULL in table T1. I want the rows for CID 500 as well with PID values as NULL.

I am new to SQL and I am trouble-shooting a problem with a home-grown app someone else wrote using PERL. It has a web interface with names of boards. I found the program where i need to add the board names into and did that. The new board names show up in the drop-down list in the Web page for the app. Alerts are sent to the new board names and show up on the new boards. Users are granted access to the new boards and they can clear items off the new boards. Yet when i try to use a report function for the new boards i added, nothing is returned. I even ran a simple SQl select statement specifying the new board names and nothing is returned. The older board names, some of which i added myself, return values. I don't know what is going on. Any help is appreciated.

I use the merge statement in a sproc to insert, update and delete records from a staging table to a production table.
In the long sql, here is a part of it,
When Matched and
((Student.SchoolID <> esis.SchoolID
OR
Student.GradeLevel <> esis.GradeLevel
OR
Student.LegalName <> esis.LegalName
OR
Student.WithdrawDate <> esis.WithdrawDate
Student.SPEDFlag <> esis.SPEDFlag
OR
Student.MailingAddress <> esis.MailingAddress)
Then update
Set Student.Schoolid=esis.schoolid,
.....
My question is how about if the column has null values in it.for example
if schoolID is null in production table is null, but in staging table is not null, will the <> return true.or if either side of <> has a null value, will it return true.
I don't want it to omit some records and causing the students records not get updated.If not return true, how to fix this?

I am working on some data that is JOINing to another table. Not a big thing. In the child table, there are different values for a single ID. I want to be able to select the Max ColorID that is Not Null, for each distinct CarID. The CarID is what I am joining the other table with. I need selecting the distinct row with the Max ColorID that is not Null. All this data is made up, so nothing looks logical in the design.
DECLARE @ColorList TABLE
(
CarID float
, ColorID int

INSERT INTO @ColorList
SELECT 1.55948815793043E+15, 9 UNION ALL

We are just upgrading a server from 2000 to 2005 and we are getting the message below when we execute a sql statement against a table with a date field with null values:
"Error converting data type DBTYPE_DBTIMESTAMP to datetime."

Hello everyone,
I have a little problem here. I need to select data from multiple columns and multiple tables, some of those columns can have NULL value. I have tried few things, and havent find the right way so far. Problem that i am incountering is that when i run SELECT statment as it is right now, i dont get back results which match search parameters but have NULL value in one or more column in select statment. How can i fix this problem?
SELECT Person2role.person2roleID,Person.firstname, Person.lastname, Person.sex
FROM Person LEFT OUTER JOIN
Person2Role ON Person.personID = Person2Role.personID
WHERE (Person.firstname LIKE '%' + ISNULL(@firstname + '%', ''))
AND (Person.lastname LIKE '%' + ISNULL(@lastname + '%', ''))
AND (Person.sex = ISNULL(@sex, Person.sex))
This is a part of SELECT statment..just so you can get the idea of what i am doing..i have few more parameters
I am working with SQL Server 2005 Express Version
Thank you,
Alex
