I appreciate how difficult it is to resolve a problem without all the
information but maybe someone has come across a similar problem.
I have an 'extract' table which has 1853 rows when I ask for all rows where
period_ = 3. The allocation table for info has 210 rows.
I have two scripts below. The first script where I specify a period on a
join, brings back 1853 lines and works. The second script where I specify
the period in the where clause only brings back 1844 rows. I have located
the missing 9 rows and they don't look any different to the other 1844 rows.
Can someone educate me as to the difference between specifying a condition
on a join and a condition in a where clause.
SELECT
a.costcentre_,
b.nett_,
a.*,
b.*
FROMextract a
LEFT OUTER JOIN
allocation b
ONa.e_reg_ = b.reg_no_
ANDb.period_ = 3
WHERE
a.period_ = 3
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.
and so on following the series for every set of same ID with 5 entries for each ID
I need to Find Maximum interval time for each ID and for condition in given message (between message like Start and Stop) I used below query and it works fine
select Id, max(CreatedDate) AS 'MaxDate',min(CreatedDate) AS 'MinDate', DATEDIFF(second,min(CreatedDate),max(CreatedDate)) AS 'MaxResponseTimeinSeconds' from Table where Id in ( SELECT distinct Id from Table where Message like 'stop') group by Id
Above query displays max response time for ID A00ze as 20 minutes, but stop message has occured at 7.15. I would need to modify the query to return max response time as 15 min(from 7.00 to 7.15).
Difference of starttime(where A00ze id started) and stoptime(where stop string is found in message).
Dear GroupI'd be grateful if you can send me on the right track in achieving this.I have three tables A,B,C outlined as follows:Table: AField: RowIDField: EntityIDField: TypeIdentifierTable: BField: RowIDField: NameTable: CField: RowIDField: NameLet's assume I've the following records:Table A:1,1,02,1,1Table B:1,SmithTable C:1,XYZCorporationThe table joins are as follows:A.EntityID = B.RowIDA.EntityID = C.RowIDI would like to select all records from Table A and display the Names fromeither Table B or Table C, depending on the Field TypeIdentifier.E.g.: SELECT Name FROM A JOIN B ON (A.EntityID = B.RowID) JOIN C ON(A.EntityID = C.RowID) IF TypeIdentifier = 0 SELECT Name FROM B IFTypeIdentifier = 1 SELECT Name FROM CResultset:SmithXYZCorporationIs this somehow possible?Thanks very much for your time & efforts!Martin
I'm trying to join two tables based on a like condition. The first table contains the full IP, e.g. '166.27.12.24' and the second contains a 2 octet range, e.g. '166.27', which I need to join.
Hello! I have two tablestable1: table2:person Manager---------- -----------------*id *id*Manager_id *Name*Branch *Title Now I want to select person.* and Mangager.Name, where person.Manager_id=Manager.id.Ok, that would be easy for me, but the point is, that the column person.Manager_id might be empty or =0 (as integer), and in that case I want to have the person.* data too.So, something like Select person.*, Manager.id From person, Manager Where person.id=4 AND person.Manager=id=Manager.id doesn't work. Can somebody explain me how to fix it? I'm using MS-SQL2000 if it is important.... Best regards!
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.
I was having a conversation with another developer about the order that the join conditions are placed. More specifically, about the order the tables are referenced in the join condition. There are two ways to do it, for example:-- Here the table that is referenced first was "declared" first. SELECT* FROM Logon LEFT OUTER JOIN Thread ON Logon.LogonID = Thread.LogonID LEFT OUTER JOIN Message ON Thread.ThreadID = Message.ThreadID
-- Here the table that is referenced first is the table being joined directly above it. SELECT* FROM Logon LEFT OUTER JOIN Thread ON Thread.LogonID = Logon.LogonID LEFT OUTER JOIN Message ON Message.ThreadID = Thread.ThreadID I realize this is not that big of a deal, but I was wondering if anyone had a good/valid reason for doing one versus the other.
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.
Update WACTS_Inventory_Part_Loc_Tbl SET WIPLT_Part_New_Qty = WIPLT.WIPLT_Part_New_Qty + tmp.MATIN_QTY FROM
WACTS_Inventory_Part_Loc_Tbl WIPLT
INNER JOIN
Temp_MatIn_Data tmp
ON
WIPLT.WIPLT_Part_Number_MSBA=tmp.PARTS_ShortID
WHERE
WIPLT.WIPLT_Location_Code='MF'
I have a Problem with this satment becoz my Temp_Matin_Data_Tmp table contains two records with the same PartNumber that is (ShortId) and the two records have two different quantities.
The WACTS_Inventory_Part_Loc_Tbl has only one Part NUmber Record and the key is the PartNUmber and Location_Code.
Now when the Update Satement runs it updates the qty only from the first record of the temp table and does not update the quantity of the second record from tne source table.
I needed to get a list of rows from a table that is not present inanother table.My problem lies in the fact that I only want SOME of the rows in table2 used in determining existance.

Is there any difference between explicit inner join and implicitinner joinExample of an explicit inner join:SELECT *FROM employeeINNER JOIN departmentON employee.DepartmentID = department.DepartmentIDExample of an implicit inner join:SELECT *FROM employee, departmentWHERE employee.DepartmentID = department.DepartmentID
I want to join 2 tables, table a and table b where b is a lookup table by left outer join. my question is how can i generate a flag that show whether match or not match the join condition ?
**The lookup table b for column id and country are always not null values, and both of them are the keys to join table a. This is because same id and country can have multiples rows in table a due to update date and posting date fields.
example table a id country area 1 China Asia 2 Thailand Asia 3 Jamaica SouthAmerica 4 Japan Asia
example table b id country area 1 China Asia 2 Thailand SouthEastAsia 3 Jamaica SouthAmerica 5 USA America
Expected output id country area Match 1 China Asia Y 2 Thailand SouthEastAsia Y 3 Jamaica SouthAmerica Y 4 Japan Asia N
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'm having a problem... maybe it's very simple, but with soo many work, right now I can't think well...
I need to filter rows in a dataflow...
I created a condition spli to that... maybe there is a better solution...
And the condition is: Datex != NULL(DT_DATE)
(Some DATE != NULL)
[Eliminar Datex NULL [17090]] Error: The expression "Datex != NULL(DT_DATE)" on "output "Case 1" (17123)" evaluated to NULL, but the "component "Eliminar Datex NULL" (17090)" requires a Boolean results. Modify the error row disposition on the output to treat this result as False (Ignore Failure) or to redirect this row to the error output (Redirect Row). The expression results must be Boolean for a Conditional Split. A NULL expression result is an error.
I am trying to write an visibility function to have message shown based on two different IIF conditions:
If behavior is to Add a customer ( if message =NAME ALREADY EXISTS, return " NAME ALREADY EXISTS", otherwize return " NAME CREATED")If behavior is to Delete a customer (( if message =NAME DOES NOT EXIST, return "NAME DOES NOT EXIST", otherwize return "NAME SUCCESSFULLY DELETED") I tried the following which doesn't work: =IIF((UCase(First(Fields!Message.Value, "DataSetName")) = "NAME ALREADY EXISTS"), "WARNING: NAME ALREADY EXIST", "NAME CREATED"), IIF((UCase(First(Fields!Message.Value, "DataSetName")) = " NAME DOES NOT EXIST"), "WARNING: NAME DOES NOT EXIST", " NAME DELETED")
I am developing a scientific application (demographic forecasting) and have a situation where I need to update a variety of rows, say the ith, jth and kth row that meets a particular condition, say, x.
I also need to adjust rows, say mth and nth that meet condition , say y.
My current solution is laborious and has to be coded for each condition and has been set up below (If you select this entire piece of code it will create 2 databases, each with a table initialised to change the 2nd,4th,8th and 16th rows, with the first database ignoring the condition and with the second applying the change only to rows with 'type1=1' as the condition.)
This is an adequate solution, but if I want to change the second row meeting a second condition, say 'type1=2', I would need to have another WITH...SELECT...INNER JOIN...UPDATE and I'm sure this would be inefficient.
Would there possibly be a way to introduce a rank by type into the table, something like this added column which increments for each type:
ID Int1 Type1 Ideal Rank by Type
1 1 1 1
2 1 1 2
3 2 1 3
4 3 1 4
5 5 1 5
6 8 2 1
7 13 1 6
8 21 1 7
9 34 1 8
10 55 2 2
11 89 1 9
12 144 1 10
13 233 1 11
14 377 1 12
15 610 1 13
16 987 2 3
17 1597 1 14
18 2584 1 15
19 4181 1 16
20 6765 1 17
The solution would then be a simple update based on an innerjoin reflecting the condition and rank by type...
I hope this posting is clear, albeit long.
Thanks in advance

All other rows are joining as expected. Why is it failing for this one row?
I'm having trouble with a multi-table JOIN statement with more than one JOIN statement.
For each order, I need to return the following: CarsID, CarModelName, MakeID, OrderDate, ProductName, Total ordered the Car Category.
The carid (primary key) and carmodelname belong to the Cars table. The makeid and orderdate belong to the OrderDetails table. The productname and carcategory belong to the Product table.
The number of rows returned should be the same as the number of rows in OrderDetails.
