Hi,
I was wanting to know if it is possible to create a left join when selecting from 3 seperate tables.
Select p.Project_name, p.project_id, cp.email_display_name, te.Mon
FROM tblProject p, tblCorpPerson cp, tblTimeEntry te
WHERE p.Project_ID = te.Project_ID
AND p.Person_ID = @PersonID
AND cp.Person_ID = p.Person_ID
I need to return all rows from tblProject, and any matching project_id's from tblTimeEntry.
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".
I need a small help in creating a join query in sql.
My two tables are A and B. A has got columns id, dname, counter and date. B has got two columns link and date. The primary key of A is the column Id whereas in table B, both are primary keys(composite key).
I need to get the records (id,dname,counter) from A which has no corresponding link in table B.
To be precise, If the table A has fields (id,dname,counter) (1,abc,2000) and if table B has no record for abc, this row should be returned from A.I hope using left outer join will help me in getting my desired result.I hope someone will be able to help me out.
Hi Folks,Lets assume I have three tables. Their layout is as follows. Pleasenote that tblPeople does not have an entry for Denver (this is myproblem)tblCity_________________CityName OCIDLA 1Denver 2tblCars_________________OCID CarVolume1 300,0002 200,000tblPeople_________________OCID PeopleVolume1 1,200,345tblDogs_________________OCID DogVolume1 234,9872 445,987I'd like to run a quiery that returns the following data set:CityName OCID CarVolume PeopleVolume DogVolumeLA 1 300000 1200345 234987Denver 2 200000 null or 0 445997My problem is the people table. Since there not entry for Denver, myquery is returning only a row for LA, nothing for Denver. Here's whtmy query looks likeSelect tblCity.CityName, tblCity.OCID, tblCars.CarVolume,tblPeople.PeopleVolume, tblDogs.DogVolumeFROM tblCityLEFT JOIN tblCars on tblCity.OCID = tblCars.OCIDJOIN tblPeople on tblCars.OCID = tblPeople.OCIDJOIN tblDogs on tblPeople.OCID = tblDogs.OCIDThis returns the following:CityName OCID CarVolume PeopleVolume DogVolumeLA 1 300000 1200345 234987I need this query to return a row for Denver as well. Any thoughtsanyone?Your insight is greatly appreciated. ericlangland at hotmail.com
course ID | year | level | course_desc | m_l ---------------------------------------------- 147 | 2006 | dip | k | 7 147 | 2006 | dip | b | 11
Hint ---- (1) see course table, select sum(m_l) from course where ID=147 and year=2006 and level='dip' = 18 (2) after query from (1), if user select ID=147, year=2006, level=dip, then m_l receiving 2 or less only (0,1,2).
What i've done shown as follow:-
SELECT a.ID, a.Year, a.Level, a.m_l - b.m_l [value_left_in_course] FROM academic a LEFT JOIN (SELECT SUM(m_l) [m_l] FROM course where ID=147 and year=2006 and level='dip' GROUP BY ID) b ON a.ID = b.ID where a.ID=147 and a.year=2006 and a.level='dip'
the result is ID | year | level | value_left_in_course ---------------------------------------------- 147 | 2006 | dip | 2
MY PROBLEM IS WHEN NO ROWS in course when ID=148, then i'm query as above the result is ID | year | level | value_left_in_course ---------------------------------------------- 147 | 2006 | dip | (null)
How to writing SQL to changing (null), then the result shown as follow? ID | year | level | value_left_in_course ---------------------------------------------- 147 | 2006 | dip | 12
Hello,I'm trying to link two tables... one for Employees and the other forTimecardsI need to get a list of employees that do not have timecards on anSPECIFIC DATEI tried the follonwingSELECT Employess.EmployeeIDFROM Employees LEFT OUTER JOIN Timecards on Employees.EmployeeID =Timecards.lmpEmployeeIDWHERE lmpEmployeeID is NULL and lmpTimecardDate = '10/24/2007'But it doesn't work. However, when I comment the date condition out(lmpTimecardDate = '10/24/2007') it works all right but It's not whatI needAnother interesting point... if I use the following query... it worksall rightSELECT Employess.EmployeeIDFROM EmployeesWHERE Employees.EmployeeID not in (select Timecards.EmployeeID fromTimecardswhere TimecardDate = '10/24/2007')I'd like to be able to use the Left Outer Join option.... Am I doingsomething wrong?... or is it that if It doesn't like the condition I'musgin in the WHERE clause (TimecardDate = '10/24/2007')Thanks for your helpPablo
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
Table A: ID (unique-identifier) Table B: ID_A (unique-identifier to A.ID, relation)
DTime (datetime)
Rows (id1 and id2 are Id examples): A: id1 id2 B: id1 and 12:00:00 (date not important) id1 and 13:00:00 id2 and 12:00:00
Example: SELECT A.ID, B.DTIME FROM A LEFT JOIN B ON B.ID_A = A.ID WHERE B.DTime < '14:00:00' ORDER BY NEWID()
When I run this, I get the three rows of table B. But what I want is to get each table A row once, and get the nearest datetime of WHERE expression from the relation of table B. So, the result must been two rows, id1 and id2, and id1 with '13:00:00' row because this is the nearest value of '14:00:00'.
How can I do this? DISTINCT trying by A.ID of SELECT, but doesn't work. Also ORDER BY B.DTime will work, but not random by NEWID() anymore.
I'm trying to join 3 tables in an outer join since I am loosing records that need to be included if I only use an inner join. I am pulling data from an MSDE database using the microsoft query tool.
The problem is that I get the message that I can't use an outer join on a query with more than 2 tables, but that can't be right can it?
I'm a SQL code novice so any help would be greatly appreciated!
SELECT Article.articleId , Article.articleName , Article.articleStatus , Articlegroup_2.ArticlegroupId , Articlegroup_2.g2_key , Articlegroup_2.g2_name , articleGroup.articleGroupId FROM HIP.dbo.Article Article, HIP.dbo.articleGroup articleGroup, HIP.dbo.Articlegroup_2 Articlegroup_2 WHERE articleGroup.articleGroupId = Article.articleGroupId AND Article.articleGroupId2 = Articlegroup_2.Articlegroup_2_Id
I'm trying to join 2 tables in an outer join, but MS Query won't let me do this because I have another 2 tables included in an inner join ("only two tables are allowed in an outer join"). I am pulling data from an MSDE database using the microsoft query tool.
I'm a SQL code novice so any help would be greatly appreciated!
Here is my existing SQL query (without the new outer join table):
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.
OLEDB source 1 SELECT ... ,[MANUAL DCD ID] <-- this column set to sort order = 1 ... FROM [dbo].[XLSDCI] ORDER BY [MANUAL DCD ID] ASC
OLEDB source 2 SELECT ... ,[Bo Tkt Num] <-- this column set to sort order = 1 ... FROM ....[dbo].[FFFenics] ORDER BY [Bo Tkt Num] ASC
These two tasks are followed immediately by a MERGE JOIN
All columns in source1 are ticked, all column in source2 are ticked, join key is shown above. join type is left outer join (source 1 -> source 2)
result of source1 (..dcd column) ... 4-400-8000119 4-400-8000120 4-400-8000121 4-400-8000122 <--row not joining 4-400-8000123 4-400-8000124 ...
result of source2 (..tkt num column) ... 4-400-1000118 4-400-1000119 4-400-1000120 4-400-1000121 4-400-1000122 <--row not joining 4-400-1000123 4-400-1000124 4-400-1000125 ...
All other rows are joining as expected. Why is it failing for this one row?
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?
Why does this right join return the same results as using a left (or even a full join)?There are 470 records in Account, and there are 1611 records in Contact. But any join returns 793 records.
select Contact.firstname, Contact.lastname, Account.[Account Name] from Contact right join Account on Contact.[Account Name] = Account.[Account Name] where Contact.[Account Name] = Account.[Account Name]
I'm trying to join 2 tables. I thought I was getting the correct results but it turns out I'm not. My Query: SELECT IVINVA, IVORDN, IVCSLN, IVRESR, IVCITM, CONVERT(varchar(12),CAST(IVIAMT as money),1) AS ExtPrice, CONVERT(varchar(12),CAST(IVPIVC as money),1) AS DistPrice, IVCSUM, IVQYCS, IVDESC, OIRESR, OIDPCT, CONVERT(varchar(12),CAST(IVPIVC - (OIDPCT / 100 * IVPIVC) as money),1) AS NetPrice FROM INVDET1_TBL LEFT JOIN ORDDIS_TBL ON ORDDIS_TBL.OIORDN = INVDET1_TBL.IVORDN AND ORDDIS_TBL.OIRESR = INVDET1_TBL.IVRESR WHERE IVORDN = '0859919' AND IVINVA = '00324024' Basically, my problem lies in the seonc condition of the LEFT JOIN. I needed to set the two tables equal my item number, because in some situations I need that logic to get the correct result. It most other cases, that item column in the ORDDIS_TBL is NULL, thus giving me the wrong results. In that case, I would want the JOIN to only be ORDDIS_TBL.OIORDN = INVDET1_TBL.IVORDN, and not include the second part. Is there a way I can condition this with an If statement, If ORDDIS_TBL.OIRESR is Null then do this join, if not, then do this? I'm confused how to get the proper result here.

I need all rows from table 1 bat right and left join gives me the same results, WHY
As you can see the ParentIndexID and ChildIndexID fields refer to tblIndices.IndexID I would like a stored procedure as follows: show all index names and show the wights for the indexID you passed. This is what I have so far and it is not correct yet. Not sure what the syntax should be.
alter PROCEDURE [dbo].[uspBasketIndices_Get]
@IndexIDint
AS
select i.IndexID, i.[Name], bc.Weight from tblIndices as i left join tblBasketConstituents as bc on i.IndexID = bc.ParentIndexID and i.IndexID = @IndexID order by i.[Name]
Any one know any facts and figures about maximum Left Joins allowed (or recommended) in one query?
I am running a MS SQL 2000 my database is full of relational data and most of my foreign keys (INT data type) are a Clustered Indexed, Usually I will only be pulling one record from collection of about a dozen tables, but the Database is expected to grow fast and become big.
Right now I have a Stored Proc that has eight(8) LEFT JOINs in it. My worry is that this query will kill me as the database approaches 50,000 records.
Hi all. My query works fine, it generates reports but not my expected result.
select d.fullname, p.nickname, p.birthdate, p.birthplace, p.gender, p.civilstatus, p.religion, p.nationality, p. weight, p.height, p.haircolor, p.eyecolor, p.complexion, p.bodybuilt, p.picture, p.dialectspoken, d.mobilephone, d.prprovince,[Age] = dbo.F_AGE_IN_YEARS( birthdate, getdate() ), c.name, c.address, c.telno, c.email, c.occupation, ed.year1, ed.year2, ed.degree, sch.schname from hremployees as e inner join psdatacenter as d on e.empdcno = d.dcno inner join pspersonaldata as p on e.empdcno = p.dcno left join hrappempcharrefs as c on e.empdcno = c.empdcno left join hrappempeducs as ed on e.empdcno = ed.empdcno left join hrsetschools as sch on ed.schoolcode = sch.schcode
the above query gives a 77 records
if i ran "select * from hremployees" generates 60 records
i think the error is in the left joining. hrappempcharrefs, hrappempeducs and hrsetschools must be left joined to hremployees.
Hi Guys, I started working with linq and vb9.0 but i have a small problem i could feagure how to solve in c# but not in vb I wanted to make left join or right join on vb 9.0 and linq is it possible or this is only c# feature ? Waiting to hear from u guys, Thanks Softy
Hello! I need to write a query using left outer join and I'm having trouble with it. I have 2 tables:customer and cust_info. I want to pull all records from customer table and cust_info table even if there is no related data in cust_info table. But I need one condition in this query:only records from customer table where cus_type in ("A","B","C"). I don't need all other types ("D","E").
So my query looks like this:
select customer.cus_name,customer.cus_address,customer.cu s_type,cus_info.status from customer left outer join cus_info ON customer.sxdat_pk = cus_info.sxdat_pk and cus_type in ("A","B","C") AND cus_info.cus_table = 'CUSTOMER'
The result should be like this:
cus_name cus_address cus_type status Amoco 457 bent A new Bingo 47 lone oak C NULL Sears 1020 Magic dr. B exist
But my query pulls records for customers with type "D" and "E" that I'm trying to exclude from result.
I have to left join 2 tables. The first consists of columns:id, description, descr_num. The second table: id, descr_num, value.
I need to extract description from table1 where descr_num is in the range , say, 1-10.
LEFT JOIN
extract value from table2 ,descr_num should be in the same range. in table2 some values from (1,10) and desc_num could be not present. BUT i want this left join to be limited as i said.
Is there any solution to this prob. without creating temp tables. Or actually can i do such a join? Thank you
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.
Hi, I'm getting the error Syntax error (missing operator) in query expression 'dbPWork.id = dbPWorkWord.work_id LEFT JOIN words ON dbPWorkWord.word_id = words.id'." on the query below. Everything looks in place to me. Do you see anything that shouldn't work?
Query:
Code:
Code:
SELECT DISTINCT dbPWork.id, description_e as description, w_id , dateStart, dateEnd FROM dbPWork LEFT JOIN dbPWorkW ON dbWork.id = dbPWorkW.work_id LEFT JOIN words ON dbPWorkW.word_id = words.id
Everything works fine until I add the second LEFT JOIN statement. Any ideas? I'm stumped.
