Transact SQL :: How To Get First Table All Rows In Left Join If Condition Is Applied On Second Table
Aug 15, 2015
I am using stored procedure to load gridview but problem is that i am not getting all rows from first table[ Subject] on applying conditions on second table[ Faculty_Subject table] ,as you can see below if i apply condition :-
Faculty_Subject.Class_Id=@Class_Id
Then i don't get all subjects from subject table, how this can be achieved.
Sql Code:-
GO
ALTER Proc [dbo].[SP_Get_Subjects_Faculty_Details]
@Class_Id int
AS BEGIN
I was writing a query using both left outer join and inner join. And the query was ....
SELECT S.companyname AS supplier, S.country,P.productid, P.productname, P.unitprice,C.categoryname FROM Production.Suppliers AS S LEFT OUTER JOIN (Production.Products AS P INNER JOIN Production.Categories AS C
[code]....
However ,the result that i got was correct.But when i did the same query using the left outer join in both the cases
i.e..
SELECT S.companyname AS supplier, S.country,P.productid, P.productname, P.unitprice,C.categoryname FROM Production.Suppliers AS S LEFT OUTER JOIN (Production.Products AS P LEFT OUTER JOIN Production.Categories AS C ON C.categoryid = P.categoryid) ON S.supplierid = P.supplierid WHERE S.country = N'Japan';
The result i got was same,i.e
supplier country productid productname unitprice categorynameSupplier QOVFD Japan 9 Product AOZBW 97.00 Meat/PoultrySupplier QOVFD Japan 10 Product YHXGE 31.00 SeafoodSupplier QOVFD Japan 74 Product BKAZJ 10.00 ProduceSupplier QWUSF Japan 13 Product POXFU 6.00 SeafoodSupplier QWUSF Japan 14 Product PWCJB 23.25 ProduceSupplier QWUSF Japan 15 Product KSZOI 15.50 CondimentsSupplier XYZ Japan NULL NULL NULL NULLSupplier XYZ Japan NULL NULL NULL NULL
and this time also i got the same result.My question is that is there any specific reason to use inner join when join the third table and not the left outer join.
I am still new to SQL and I am having trouble obtaining the results I need from a query. I have worked on this command for some time and searched the internet but cannot seem to still get it correct.
I have a table called Patient. It's primary key is pat_id.
I have a second table called Coverage. It has no primary key. The foreign keys are pat_id, coverage_plan_id, and hosp_status.
I have a third table called Coverage_History. It has a primary key consisting of pat_id, hosp_status, copay_priority, and effective_from.
I want to get the pat_id and all the coverage information that is current. The coverage table contains specific insurance policy information. The coverage_history table will indicate the effective dates for the coverage. So the tables could contain something like this:
Patient (pat_id and lname) P123 Monto P124 Minto P125 Dento P126 Donto
Coverage (pat_id, coverage_plan_id, hosp_status, policy_num) P123 MED1 OP A1499 P123 ACT4 OP H39B P124 MED1 OP C90009 P124 RAC OP 99KKKK P124 RAC OP 99KKKK P124 MED1 OP C90009 P125 ARP OP G190 P126 BCB OP H88
Coverage_History (pat_id, hosp_status, copay_priority, effective_from, coverage_plan_id, effective_to) P123 OP 1 20150102 MED1 NULL P123 OP 2 20150102 ACT4 NULL P124 OP 1 20150203 RAC 20150430 P124 OP 2 20150203 MED1 20150430 P124 OP 1 20150501 MED1 NULL P124 OP 2 20150501 RAC NULL P125 OP 1 20150801 ARP NULL P126 OP 1 20150801 BCB 20160101
select p.pat_id, p.lname, ch.coverage_plan_id, ch.hosp_status, ch.effective_from, ch.effective_to, ch.copay_priority, from patient p left join ( coverage_history ch left join coverage c on ch.coverage_plan_id = c.coverage_plan_id and ch.patient_id = c.patient_id and (ch.effective_to is NULL or ch.effective_to >= getdate() ) ) on ch.patient_id = p.patient_id
where ( ch.effective_to is NULL or ch.effective_to >= getdate() )
So I want to see:
P123 Monto MED1 OP 20150102 NULL 1 P123 Monto ACT4 OP 20150102 NULL 2 P124 Minto MED1 OP 20150501 NULL 1 P124 Minto RAC OP 20150501 NULL 2 P125 Dento ARP OP 20150801 NULL 1 P126 Donto BCB OP 20150801 20160101 1
I have a query that based 2 tables. I wrote a query with a left join on the base table but the result set returns multiple rows for each occurrence in the second table because of the left join. I want but to return all records from on table A and only matching records from table B which id but I would wan tit to keep return them vertically as the because it make it difficult to read when put in a spreadsheet. It want it to return the values horizontally so the rows are not increasing for each occurrence on table b.
Hi, I want to get join of two tables A and B in such a way that all the Data from A for a particular Date should be extracted and then from table B Reqired column should selected against that data (it can be null). But if i use the following query: 1) Select A.*,B.Reqired from A Left Outer Join B on A.Same=B.Same Where A.Date = '1/22/2008' it first joins the Table A and B (A contains millions of records) which takes a lot of time and then where is applied which takes a lot of time. And if I use the following query: 2)Select A.*,B.Reqired from A Left Outer Join B on A.Same=B.Same AND A.Date = '1/22/2008' in this case A.Date = '1/22/2008' has no effect and all the data from the table A comes. I have also tried first making the temp table for A.Date = '1/22/2008' and the joining with B but its cost is same as 1. For this purpose Oracle allows the use of (+) operator like: 3)Select A.*,B.Reqired from A,B Where A.Same=B.Same(+) AND A.Date = '1/22/2008' which means all data from A for '1/22/2008' Plus B.Required against it whether its null or not. Please let me know if there is a way around in MS SQL SERVER 2005. Thanx.
Left join on condition has no effect in the left table itself? I have two tables: one named student
studentID studentName -------------------------------------------------- -------------------------------------------------- 1 Jom 2 Jim 3 Tom 4 Kate 5 LinDa 6 DaiAnna
The other is grade table
studentID subject grade -------------------------------------------------- -------------------------------------------------- ----------- 1 math 90 2 Chinese 90 1 Chinese 80 3 math 98 4 math 76
And I write two SQLs 1: select students.studentName , grades.grade as math_grade from student as students left outer join grade as grades on students.studentID = grades.studentID and grades.subject = 'math' 2: select students.studentName , grades.grade as math_grade from grade as grades left outer join student as students on students.studentID= grades.studentID and grades.subject = 'math'
After execute, the answer is 1: studentName math_grade -------------------------------------------------- ----------- Jom 90 Jim NULL Tom 98 Kate 76 LinDa NULL DaiAnna NULL
2: studentName math_grade -------------------------------------------------- ----------- Jom 90 NULL 90 NULL 80 Tom 98 Kate 76
The math_grade of the second answer is all the grade rows of the grade table. on grades.subjec='math' has no effect. Why SQL will act it like this? I know it's not a bug. But I really wanna know the inside work. Thanks in advance, with very appreciation.

To join the table but MUST follow the condition as bitActiv = TRUE: select emp.nvcEmpName, emp.nvcEmpAddress, ety. nvcEmployeeType from cst_EmpProfile emp left join cst_EmpType on emp.intEmployeeTypee = ety.intEmpType and emp.bitActiv = 1.
But, the sql statement doesnt output the my expected result. Because the data row return must be 1st and 2nd row as it bitActiv = true. So, how's I going achieve what i want. tq.
I have an problem with the order of the results after a join.
My first query works fine and the order of field Name ist correct.
Select * FROM (SELECT * FROM dtree A1 WHERE A1.Subtype=31356 AND A1.DataID IN (select DataID from dtreeancestors where AncestorID=9940974)) t
When I do a join the order of the left table changes
Select * FROM (SELECT * FROM dtree A1 WHERE A1.Subtype=31356 AND A1.DataID IN (select DataID from dtreeancestors where AncestorID=9940974)) t, llattrdata A4 WHERE t.DataID = A4.ID
How can I do a join and keep the order of the left table?
I have a query that include a single LEFT JOIN. I would like to be able to select at most 1 row of the second table (providing that the JOIN represents a one to many relationship).
Does anyone knows how to do that? Thanks in advance, Joannès
I have a query that has a left join with a large partitioned table. The partitioned table has 10s of millions of records, and each partition has about 100,000 records.
The left join is part of an insert that gets a column from the partitioned table, if the column exists. The query contains the partition ID and all other joined columns are part of a non-clustered index.
Through the profiler, I found that there were millions of reads and the execution plan was giving me a table scan on the partitioned table.
I changed the query to do the insert followed by an update with inner join. That did the trick, but it worries me that SQL Server 2014 behaves differently from 2012 or 2008R2, which can make upgrading very time consuming.
I need to find the rows that exist in one table but not in the otherwith this condition:(prod_name exist in table1 and not in table2.prod_name ) AND(prod_name exist in table1 and not in table2.'S'+prod_name )explanation:i want to know if the product not exit and if the combination of thecharachter "S" with the product Name also not exist at the othertableB.Ryuvi
Looking to improve performance of the following code.
It basically generates future days for each dog. So there is a dog table and a day table with every day.
These 2 table cross join and then fill in missing rows. As time moves i will fill in further future dates but will need the initial insert to be a reasonable query.
All columns are covered by index's but the queries at the end take quite a long time. I would hope for index scan to just point out the missing rows especially on the final query.
How to make the last query as fast as possible.
IF OBJECT_ID('dbo.[AllDates]', 'U') IS NOT NULL DROP TABLE dbo.[AllDates] CREATE TABLE dbo.[AllDates] ( [Date] date not null PRIMARY KEY ) ;WITH Dates AS

I am trying to tweak some code which is used to display the newest comments left on photos created by my members.
The existing code is this:
SELECT top 15 pnumber,pcomment,puser FROM photocomments order by pdate DESC
So the latest comment left was for photo #210879 from user "Cla" (redacted user names). The 2nd newest comment would be for photo #211072 from a member named "mo". pdate is a date field
However for the script I have coded I don't want all of the photo comments to show up. This is because I use access levels based on the type of location (higher levels mean more restricted galleries). I check the access levels as I go through the recordsets.
I use this method to get the top 15 comments:
SELECT top 15 pnumber,pcomment,puser FROM photocomments order by pdate DESC
Now I have to use two other tables to determine the access level. Since PHOTOCOMMENTS is just a list of photo #'s and the people who left comments for those photos, I need to:
a) determine what location the photo is from and b) determine the access level of that location
I use: select creator,access from locations where id=(select dir from photos where id="&pnumber&")"
This is a two step process as you can see. The first part is:
select dir from photos where id=(pnumber)
ID is the same value as pnumber seen in PHOTOCOMMENTS. That is to say PHOTOS.ID = PHOTOCOMMENTS.PNUMBER
If I haven't confused you yet, the executed code for the first example would be:
select dir from photos where id=210879
which would get me a value for DIR. DIR is the location number which would be:
select creator,access from locations where id=(dir value)
Just to simplify it a bit....
There are three tables (shown below)
PHOTOCOMMENTS PHOTOS LOCATIONS
I need to: SELECT top 15 pnumber,pcomment,puser FROM photocomments order by pdate DESC (first table shown)
but then also
select creator,access from locations (The last table shown) where id=(select dir from photos where id="&pnumber&")"
So the first table PHOTOCOMMENTS has to also join PHOTOS table where PHOTOS.DIR = PHOTOCOMMENTS.PNUMBER in order to get the value of "DIR" and then DIR is joined to the LOCATIONS tables where PHOTOS.DIR = LOCATIONS.ID
Here is the actual code, which I am trying to make into a single SQL command
strSQL = "SELECT top 15 pnumber,pcomment,puser FROM photocomments order by pdate DESC" set ors = oconn.Execute(strSQL) tl = 0 do until ors.eof or tl > 15 ' until we have 15 results because not every recordset will be of the proper security level
[Code] ....
Bonus points if you can also get it to select from LOCATIONS only WHERE userlevel >= 2
I have around 3 tables having around 20 to 30gb of data. My table A related to table B by a FK and same way table B related to table C by FK. I would like to delete all rows satisfying certain condition from table A and all corresponding related records from table B and C. I have created a query to delete the grandchild first, followed by child table and finally parent. I have used inner join in my delete query. As you all know, inner join delete operations, are going to be extremely resource Intensive especially on bigger tables.
What is the best approach to delete all these rows? There are many constraints, triggers on these tables. Also, there might be some FK relations to other tables as well.
SELECT A.EmpId,A.IncidentDate FROM EmployeePoints1 as A WHERE IncidentDate= (SELECT MAX(IncidentDate) FROM EmployeePoints1 WHERE EmpId = A.EmpId) AND (DATEADD(day,28,DATEADD(WEEK, DATEDIFF(WEEK, 0,A.IncidentDate), 0)) < DATEADD(WEEK, DATEDIFF(WEEK, 0,GetDate()), 0)) AND (A.IncidentCode = 'I' OR A.IncidentCode = 'A') LEFT JOIN EmployeeTotalPoints1 ON EmployeeTotalPoints1.EmpId = A.EmpId
I am working on SQL server 2005 Reports. I have one report, one dataset is assigned to it, and one table which displays it. Now I come accros requirement that, the column value in the filter condition for the table is present in one textbox.
I can not use textbox i.e. reportItems in filter condition. Can someone suggest me how to use textbox value in filters?
I want to display parent/child records on report. I am not getting the proper solution.
The data is like this:
Sequence ItemCode IsParent
1 XYZ 0 'do not have child record
2 PQR 1 'have child records with sequence no 3
3 ASD 0
3 AFDGE 0
3 VDC 0
4 ASR 1 'have child records with sequence no 5 5 ASR 0
If IsParent = 1, that record has child records with sequence = parent sequenece + 1
I think u can understand the data I need to bind, and it is like:
XYZ
+ PQR
ASD
AFDGE
VDC
ASR
On + click we can do show/hide of child records.
I m not getting how to achive this in SQL server report. Can u give some hint?
SELECT [tblSections].[pageTitle], [tblSections].[sectionURL], [tblSectionContents].[articleID], [tblSectionContents].[fileID], [tblSectionContents].[linkID], [tblCopy].[copyText], [tblFiles].[fileName], [tblFiles].[fileCaption], [tblGroupings].[grouping], [tblLinks].[linkURL] FROM [tblSections] LEFT JOIN [tblSectionContents] ON [tblSectionContents].[sectionID] = [tblSections].[id] LEFT JOIN [tblCopy] ON [tblSectionContents].[articleID] = [tblCopy].[id] LEFT JOIN [tblFiles] ON [tblSectionContents].[fileID] = [tblFiles].[id] LEFT JOIN [tblGroupings] ON [tblFiles].[groupingID] = [tblGroupings].[id] LEFT JOIN [tblLinks] ON [tblSectionContents].[linkID] = [tblLinks].[id] WHERE [tblSections].[id]=2 ORDER BY [tblSectionContents].[articleID], [tblSectionContents].[fileID], [tblSectionContents].[linkID]
If I pass it the ID of a section that has files or copy or [stuff in other tables] attached, then I get a result set that makes sense.
But if I pass it a section ID that doesn't reference any other content tables (ie: the section just has a title and a link URL), I don't get anything back.
Shouldn't it should still get me the fields from the row in tblSections that matches the ID I'm passing it?
I have a SQL script to insert data into a table as below:
INSERT into [SRV1INS2].BB.dbo.Agents2 select * from [SRV2INS14].DD.dbo.Agents
I just want to set a Trigger on Agents2 Table, which could delete all rows in the table , before carry out any Insert operation using above statement.I had below Table Trigger on [SRV1INS2].BB.dbo.Agents2 Table as below: But it did not perform what I intend to do.

SELECT U.UserFamilyName, F.FamilyName FROM Users U LEFT JOIN User_Friends F ON U.UserID = F.UserID WHERE U.UserName = ‘JOHN’
How do I adjust my query to select just the very first record from Users_friends, I want only the top first one.And if there are no friends how can I return an empty string instead of Null.
SELECT * FROM a LEFT OUTER JOIN b ON a.id = b.id instead of
SELECT * FROM a LEFT JOIN b ON a.id = b.id
generates a different execution plan?
My query is more complex, but when I change "LEFT OUTER JOIN" to "LEFT JOIN" I get a different execution plan, which is absolutely baffling me! Especially considering everything I know and was able to research essentially said the "OUTER" is implied in "LEFT JOIN".
SELECT PR.WBS1, PR.WBS2, ledgerar.invoice, SUM(CASE WHEN ledgerar.transtype = 'in' AND ledgerar.period = '200405' THEN ledgerar.amount * - 1 END) AS amount FROM PR LEFT OUTER JOIN LedgerAR ON LedgerAR.WBS1 = PR.WBS1 AND LedgerAR.WBS2 = PR.WBS2 AND LedgerAR.WBS3 = PR.WBS3 WHERE (LedgerAR.wbs1 = '001-333') AND ledgerar.period = '200405' GROUP BY pr.wbs1, pr.wbs2, ledgerar.invoice
But I don't know how to get the query to display all of wbs2 whether it is null or not. So, for each invoice number there should be five records according to the wbs2 codes (500, 100, 140, 150, 160)
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
We have a service that inserts some rows into a parent table (P) and child table (C). This operation is atomic and performed within a transaction.
We also have a service that queries these tables such that rows are (should only be) returned from P where there are no children for that parent.
The SQL that performs this is simplified below:
SELECT P.SomeCol FROM P LEFT OUTER JOIN C ON P.PKofP_Value = C.PkofP_Value WHERE C.PkofPValue IS NULL AND P.SomeOtherCol=0
Our expectation is that the query service should only return rows from P where there are no rows in C.
However, this seems not to be the case, and occasionally we find that rows from P are returned where there are matching rows in C.
We are sure that the process that inserts rows into P and C does so within a single transaction.
We have traced this with SQLTrace and can see the txn stag and committing and all operations using the same transactionid within the transaction.
We are running the default isolation level committed.
In SQLTrace we can see the query process start, the inserter process start and complete and then the query process continue (after presumably being blocked).
So how can the query process "miss" the child rows and return the parent from the above query?
Is it possible that, in this isolation level, the inserter process can block the query process such that when the inserter process commits and when the query process continues it does not see the child rows inserted because they were inserted in the table/index "behind" where the query process has already read - some kind of phantom phenomenon?
I am using SQL Server 2008.Each stock item will have default 4 document type (1, 5, 6, 7) and each will have 3 zone's (1, 2, 3) to qualify. Each zone will be updated to 1 for that document type if the item successfully pass through it. If all zone are NULL means no transaction. How to retrieve only the failed rows which means not all zone are 1 or NULL.In the image GJ-00064 has one row failed. So how to get the count of failed rows for each item
I want to join this table with itself on reg. no. But not all the rows in table must be joined.
But for example, rows with load_date 01-07-2015 to be joined with rows with load_date 02-07-2015. And the rest of the rows should not used in join (for example, rows having other load_dates)
I need to create a query to get 1 row per location and get the minimum PolicyBookingDt and RowUpdateDt from the policy table. All the attributes from the Location table should also be from the Policy that has the minimum PolicyBookingDt.
So from the above example, i need to get the following:
Getting a little confused on how to create the syntax for this.
select sq.*, p.numero, p.nombre from paf p right outer join dbo.GetListOfSquaresForShippingLot(@lot) sq on sq.number = p.numero and sq.version = p.numero
The @lot parameter is declared at the top ( declare @lot int; set @lot = 1; ). GetListOfSquaresForShippingLot is a CLR TVF coded in C#. The TVF queries a XML field in the database and returns nodes as rows, and this is completed with information from a table.
If I run a query with the TVF only, it returns data; but if I try to join the TVF with a table, it returns empty, even when I'm expecting matches. I thought the problem was the data from the TVF was been streamed and that's why it could not be joined with the data from the table.
I tried to solve that problem by creating a T-SQL multiline TVF that is supposed to generate a temporary table. This didn't fix the problem.
What can I do? Does anybody know if I can force the TVF to render its data somewhere so the JOIN works? I was thinking a rowset function could help, but I just can't figure out how.
PLEASE HELP!!!!
Let me know if you want the code for the CLR TVF. This is the code for the T-SQL TVF:
CREATE FUNCTION [dbo].[GetTabListOfSquaresForShippingLot] ( @ShippingLot int ) RETURNS @result TABLE ( Number int, Version int, Position smallint, SubModel smallint, Quantity smallint, SquareId nvarchar(5), ParentSquareId nvarchar(5), IsSash smallint, IsGlazingBead smallint, Width float, Height float, GlassNumber smallint, GlassWidth float, GlassHeight float ) AS BEGIN INSERT INTO @result SELECT * FROM dbo.GetListOfSquaresForShippingLot(@ShippingLot)
