Nested Join To Return Only Rows With Null Values From All Tables
Oct 17, 2007
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.
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?

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 :
I have a pivot transform that pivots a batch type. After the pivot, each batch type has its own row with null values for the other batch types that were pivoted. I want to group two fields and max() the remaining batch types so that the multiple rows are displayed on one row. I tried using the aggregate transform, but since the batch type field is a string, the max() function fails in the package. Is there another transform or can I use the aggragate transform another way so that the max() will work on a string?
I have a database that has 100,000+ records in a table. Am I better off returning all of the records from a search even if it is 50,000 records or is it better to do a SELECT COUNT(*) And nested SELECT TOP x statements to only return 1 page of results? What is the best practice for a situation like this? SELECT * FROM myTable LEFT OUTER JOIN ... LEFT OUTER JOIN......WHERE something=@something AND another.... AND... OR SELECT COUNT(*) FROM myTable LEFT OUTER JOIN ... LEFT OUTER JOIN......WHERE something=@something AND another... AND... ORDER BY @OrderAnd SELECT TOP(@pagesize) FROM (SELECT TOP(@pagesize * @pagenum) FROM myTable LEFT OUTER JOIN ... LEFT OUTER JOIN......WHERE something=@something AND another... AND... ORDER BY @Order)ORDER BY @revOrder
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?
Hello, I have a stored procedure that accepts a number of different input parameters that populate some variables in my stored procedure. I want to have this stored procedure return nothing if some of these variables aren't filled out (they are populated by a search page the user fills out). I'm not very familiar with writing stored procedures, so any help you can give me is appreciated. Thanks!
I'm creating a 'dynamic where clause' with 15 parameters. I was using coalesce with the example below and it's working fine until it encounters a null value. I was trying to use nullif with coalesce to no avail. Can someone show me based on my example below how I can incorporate nullif with coalesce. Thanks in advance for you help.

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
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.
I have a subscriptions table that has many line items for each record. Each line item has a different type, dues, vol, Chapt.

Hi all My query has some inner joins to some tables. And problem is when any ON clause get null as value, the correspondent record is not displayed. SELECTTableA.A, TableB.AFROM TableAINNER JOIN TableB ON TableA.A = TableB.A What I did try: SELECTTableA.A, TableB.AFROM TableAINNER JOIN TableB ON TableA.A = TableB.A OR TableA.A IS NULL (but It generates redundant values from TableB) I need to show all values even that value from Tablea is null Thank a lot for any help
I'd like to return the following result set: CompanyModules.CompanyID | Modules.Name | Present 1 | A | True 1 | B | True 1 | C | True 2 | A | True 2 | B | False 2 | C | False
What would be the query for this? Thanks.
Edit: This is the query I have tried:
select CompanyModules.CompanyID, Modules.Name, count(Modules.ID) as Present from
CompanyModules RIGHT outer Join Modules on CompanyModules.ModuleID = Modules.ID
group By CompanyModules.CompanyID, Modules.Name
Order by CompanyID
However, it only returns a partial result set:
CompanyModules.CompanyID | Modules.Name | Present 1 | A | 1 1 | B | 1 1 | C | 1 2 | A | 1
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.
SELECT A.CID, A.ANI, A.PID, B.RD FROM T1 AS A CROSS APPLY GIVERD(A.PID) B
This should be a simple solution, but it has been a long time since I've done any query writing (mostly in Oracle) and I am stumped, so here goes:
We are in the process of converting Access database to MSSQL with web form front ends.
I have a table, all columns are nullable, and want users to be able to query from a form, which has a field for each column and defaults to a % wild card for the entered value.
I want the users to be able to put any string in any field, and have it return each row that matches that, including rows with null values in the other columns, but not the column with the entered criteria.
Here is a sample of the data:
Code: SQL> select * from test;
COL1 COL2 COL3 COL4 ----- ----- ----- ----- this is a test this is not test this is not this is test too is test too is too is too
7 rows selected.
Now, if I have this SQL run, it will return only rows that have no nulls in any columns:
Code: select col1, col2, col3, col4from test where col1 like'th%' and col2 like '%' and col3 like '%' and col4 like '%';
COL1 COL2 COL3 COL4 ----- ----- ----- ----- this is a test this is not test this is test too
Now, if I use an OR clause for each column, this mostly works, but the trouble is it will also return rows with null values for the field that has criteria entered in it:
Code: select col1, col2, col3, col4from test where (col1 like'th%' OR col1 is null) and (col2 like '%' OR col2 is null) and (col3 like '%' OR col3 is null) and (col4 like '%' OR col4 is null); COL1 COL2 COL3 COL4 ----- ----- ----- ----- this is a test this is not test this is not this is test too is test too is too is too
The idea is to only select the first 4 rows in the above example.
I was playing with ISNULL in the select clause, but all it does is substitute a string for a null, and I think CASE will do the same thing.
Is there a way I can write this query so it will return rows with NULL values in any column, except the one(column) that has user entered criteria in it?
I cannot in the life of me understand what goes wrong here... In a webapplication (C#.NET) I traced an inability to retrieve existing records to SQL Server, where I cannot do the same either. The problem is that in the parameterized query, some fields can be null, and thus when the corresponding fields in the database record are null also, they should be selected. But this won't happen for some reason.
I wrote a test SQL statement that gives me the same bogus:
DECLARE @institution int, @collection int, @serialnr int, @subnr nvarchar(50)SET @institution = 1 SET @collection = 1SET @serialnr = 240 SET @subnr = NULLSELECT ID, Institution, Collection, SerialNumber, SubNumber, AccessionYear, Sagsnummer, DanekraeNr, TaxonIdentified, Stratigraphy, TypeStatus, PlacementRoom, PlacementCabinet, PlacementDrawer, UnitNotesFROM SpecimensWHERE (Institution = @institution) AND (Collection = @collection) AND (SerialNumber = @serialnr) AND (SubNumber = @subnr) Now there is at least one row with corresponding fields values (1, 1, 240, null), but it won't be selected! What is wrong!?
I have two table, tblCharge and tblSentence, for each charge, there are one or more sentences, if I join the two tables together using ChargeID such as: select * from tblCharge c join tblSentence s on c.ChargeID=s.ChargeID , all the sentences for each charge are returned. There is a field called DateCreated in tblSentence, I only want the latest sentence for each charge returned, how can I do this? I tried to create a function to get the latest sentence for a chargeID like the following: select * from tblCharge c join tblSentence s on s.SentenceID=LatestSentenceID(c.ChargeID) but it runs very slow, any idea to improve it? thanks,
I joined different tables and got a result like this:
result | process | goal | date | ------- ---------- ------ ----------- ok | process4 | 1 | 12.10.2013 bad | process1 | 2 | 13.10.2013 ok | process1 | 4 | 12.12.2013 good | process4 | 1 | 03.01.2014 ok | process1 | 3 | 10.04.2013 bad | process3 | 6 | 09.01.2014 bad | process4 | 3 | 30.12.2013 best |NULL| NULL
Now I want to count the results by counting the processes and group them by the result.
But it should be count the latest result per process only, e.g. for goal "1" just "good" at 03.01.2014. I solved that with a subquery (date=SELECT MAX(...)..).
But now the result "best" disappears, because that column has no date.
Secondly I want to count results for a specific process, e.g. for process4. Every goal has max. one process, with different dates. But one process could have more than one goal.
I want to have this result for process4:
count | result ------ ------- 1 | good 1 | bad 0 | ok 0 | best
But I got only:
count | result ------ ------- 1 | good 1 | bad
I have tried a lot, but nothing works.
The whole result (best, good, ok, bad) are stored in an other table and I joined it.
Hey. I need to substitute a value from a table if the input var is null. This is fine if the value coming from table is not null. But, it the table value is also null, it doesn't work. The problem I'm getting is in the isnull line which is in Dark green color because @inFileVersion is set to null explicitly and when the isnull function evaluates, value returned from DR.FileVersion is also null which is correct. I want the null=null to return true which is why i set ansi_nulls off. But it doesn't return anything. And the select statement should return something but in my case it returns null. If I comment the isnull statements in the where clause, everything works fine. Please tell me what am I doing wrong. Is it possible to do this without setting the ansi_nulls to off??? Thank you
set ansi_nulls off
go
declare
@inFileName VARCHAR (100),
@inFileSize INT,
@Id int,
@inlanguageid INT,
@inFileVersion VARCHAR (100),
@ExeState int
set @inFileName = 'A0006337.EXE'
set @inFileSize = 28796
set @Id= 1
set @inlanguageid =null
set @inFileVersion =NULL
set @ExeState =0
select Dr.StateID from table1 dR
where
DR.[FileName] = @inFileName
AND DR.FileSize =@inFileSize
AND DR.FileVersion = isnull(@inFileVersion,DR.FileVersion)
Is there a way to join tables that have multiple matches to each other (2 records in one table and 2 in another) so that you get 2 records returned instead of 4 with only 1 JOIN ON qualifier?
In our warehouse DB, there is a master location table, an inventory location table, and physical table for counting all product in the warehouse. The master location table has one record per location, but there could be multiple items in that location so my outer join from the master location to the inventory table returns something like:
select M.MASTER_LOC, C.AS ORIG_ITEM, C.ORIG_LOT, C.ORIG_QTY from M_LOC M LEFT OUTER JOIN C_INVT C ON M.MASTER_LOC = C.INVT_LOC order by M.LOC_CODE
My join is returning 4 rows for location 01-03-A which I understand, but I'm wondering if I can sort within the join or make some temp tables so that instead of:
select M.MASTER_LOC, C.AS ORIG_ITEM, C.ORIG_LOT, C.ORIG_QTY, E.AS CNTD_ITEM, E.CNTD_LOT, E.CNTD_QTY from M_LOC M LEFT OUTER JOIN C_INVT C ON M.MASTER_LOC = C.INVT_LOC LEFT OUTER JOIN E_PHYS_INVT E ON M.MASTER_LOC = E.LOC_CODE order by M.LOC_CODE
I am new in SQL and i need do a query where I need sum values from 2 tables, when i do it the Sum values are not correct. this is my query
SELECT D.Line AS Line, D.ProductionLine AS ProductionLine, D.Shift AS Shift, SUM(CAST(D.DownTime AS INT)) AS DownTime, R.Category, SUM(Cast(R.Downtime AS INT)) AS AssignedDowntime, CONVERT(VARCHAR(10), D.DatePacked,101) AS DatePacked FROM Production.DownTimeReason R left JOIN Production.DownTimeHistory D
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)
I have to join two tables and i need to fetch All records from @tab2 and only max date record from @tab1 that ID is present in Tab2
1.) @Tab1 have multiple records for each ID
2.) @Tab2 also have multiple records for each ID
3.) Kind of Lef Outer join those tables with ID and take all records from @tab2 and only Max of date from @tab1 and order by ID and Date
Note: @Tab1 always have lesser dates than @tab2 for each ID
Tables looks like as follows
declare @tab1 table (id varchar(3), effDt Date, rate int) insert into @tab1 values ('101','2013-12-01',5) insert into @tab1 values ('101','2013-12-02',2) insert into @tab1 values ('101','2013-12-03',52)
[code]....
In the given ex, ID 103 should not come as it is not present in @tab2, ID 104 should come even it is not present in @tab1 as we ahve to use left outer join Result should like follows.
I am having problems joining these two tables and returning the correct values. The issue is that i have a work order table and a revenue table. I only want to return the sum of the revenue when the revenue comes after the work order date. That is simple enough, but it gets tricky when there are multiple work orders for the same ID. for those instances, we only want the sum of the revenue if it shows up post the work order date and if it is before any other work order date. So ID 312187014 should only have the 9-5 revenue from below, not the 7/7 or 8/6 revenue because the 8/7 work order date is after those revenue dates and thus will not have any revenue tied to it because there is a 9/3 work order that ties to the 9/5 revenue. Additionally the 412100368 ID has a 7/7 work order that ties to the 7/26 revenue, and the 8/7 work order will tie to the 8/23 and 9/20 revenue
--===== Create the test table with
CREATE TABLE #workorder ( Id varchar(20), wo varchar(10), wodate datetime, amount float ) GO CREATE TABLE #revenue
