HI ,
I am joining two tables
a--3 million records
b--58 million records
i am doing inner join based on common column, but
it is doing cross join, giving 174 million records..
When i saw showplan it is showing
physical---merge join
logical ---inner join.
Could any one pls suggest me..
thank u
i want to create a join query (for view) that will show one data per day for each agent. just a select query joing these two tables..Seems like the date field is given me problem i want result like below
I have the following tables:members--------------member_idmember_tpc_id ( = tpc.tpc_id)tpc------tpc_idcourse------------course_idtpc_assignment---------------------------tpc_assignment_idcourse_idenrollment-------------------member_idcourse_idenrollment_status Now I want to select all members where member_tpc_id>0 and get the enrollment_status of each member in each course where course_id IN (Select course_id From tpc_assignment)Now what i did was get all the members and then all the courses and did a cross join between them. There are about 1900 members and 80 courses and when I do a cross join I get 1900*80 rows (152000) and the status of each member for all the 80 courses. If not enrolled it returns Not Enrolled (i have a UDF which takes a member_id and a course_id and returns the status). The BIG problem is that its taking about 6-8 mins to run the query and as a result its timing out on the aspx page. Can someone please tell me how I can do what i am trying to do without using the cross join because I suspect its the culprit here. The query I came up with is Select *, dbo.returnStatus(temp1.user_id, temp2.course_id) As Status, (Select tpc_title From tpc Where tpc_id = temp1.member_tpc_id) As Tpc_Title From (Select member_id As user_id, member_name, member_tpc_id From members Where member_tpc_id> 0 And organization_id = '1' )temp1 cross join (Select course_id As course_id, course_title As course_title From course Where course_id IN (Select course_id From tpc_assignment Where tpc_requirement_id IN (Select tpc_requirement_id From tpc_requirement) And course_id<>0 And organization_id = '1') )temp2 Order By member_name, Tpc_TitlePlease help. Thank you.

hi, I have settup up sql mail and did the following: 1. created an E-mail account and configured Out look by creating a pop3 mail profile. tested it by sending and receiving mail, that is ook 2. I Created one domain account for MSsqlserver and Sql Agent service. both services use same account and start automatically in the control panel-services 3. I used the profile that I created in outlook to test the sql mail but got an error: Error 22030 : A MAPI error ( error number:273) occurred: MapiLogon Ex Failed due to MAPI Error 273: MAPI Logon Failed
I really do not know what went wrong. I followed the steps from bol and still having a problem. Am I missing something.
I do have a valid email account I do have a valid domain account I tested outlook using the email account and it worked. so why sql server does not recognise MAPI.
My next question, How to configure MAPI in Sql server if what I did was wrong.
Hi, I have 2 windows 2000 server in cluster with sql server 2000 enterprise edition installed. I have activated the Server-Requested Encryption by using the sql server network utility (Force Protocol Encryption). After this, I have stoped sql server service. But I can't start it at this moment. The error is: 19015: The encrypton is required but no available certificat has been found.
Hello, I am facing a huge problem in my sql server database using access as a front end.The main problem is trying to execute queries "views" ,since they reside on sql server now,and using variables or parameters in reports and forms to filter on this query. Ex. how can the following be implemented using the same query but in sql server? Access ------ SELECT MAT_Charts.YYYYMM FROM MAT_Charts WHERE ((([Area_Code] & "-" & [GROUP_CODE])=[Reports]![MAT_Chart_C1].[MAT_Key])) GROUP BY MAT_Charts.YYYYMM;
It is specifically this statement in which I am interested: [GROUP_CODE])=[Reports]![MAT_Chart_C1].[MAT_Key]))
I was writing a query using both left outer join and inner join. And the query was ....
SELECT Â Â Â Â Â Â Â S.companyname AS supplier, S.country,P.productid, P.productname, P.unitprice,C.categoryname FROM Â Â Â Â Â Â Â Production.Suppliers AS S LEFT OUTER JOIN Â Â Â Â Â Â (Production.Products AS P Â Â Â Â Â Â Â Â 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 Â Â Â Â Â Â Â S.companyname AS supplier, S.country,P.productid, P.productname, P.unitprice,C.categoryname FROM Â Â Â Â Â Â Â 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?
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.
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?
I have a merge join (full outer join) task in a data flow. The left input comes from a flat file source and then a script transformation which does some custom grouping. The right input comes from an oledb source. The script transformation output is asynchronous (SynchronousInputID=0). The left input has many more rows (200,000+) than the right input (2,500). I run it from VS 2005 by right-click/execute on the data flow task. The merge join remains yellow and the task never finishes. I do see a row count above the flat file destination that reaches a certain number and seems to get stuck there. When I test with a smaller file on the left it works OK. Any suggestions?
A piece of software I wrote starting timing out on a query that left outer joins a table to a view. Both the table and view have approximately the same number of rows (about 170000).
The table has 2 very similar columns, one is a varchar(1) and another is varchar(100). Neither are included in any index and beyond the size difference, the columns have the same properties. One of the employees here uses the varchar(1) column (called miscsearch) to tag large sets of rows to perform some action on. In this case, he had set 9000 rows miscsearch value to "g". The query then should join the table and view for all rows where miscsearch is set to g in the table. This query takes at least 20 minutes to run (I stopped it at this point).
If I remove the "where" clause and join all rows in the two tables, the query completes in about 20 seconds. If set the varchar(100) column (called descrip) to "g" for the same rows set via miscsearch, the query completes in about 20 seconds.
If I force the join type to a hash join, the query completes using miscsearch in about 30 seconds.
So, this works:
SELECT di.File_No, prevPlacements, balance,'NOT PLACED' as status FROM Info di LEFT OUTER HASH JOIN View_PP pp ON di.ram_file_no = pp.file_no WHERE miscsearch = 'g' ORDER BY balance DESC
and this works:
SELECT di.File_No, prevPlacements, balance,'NOT PLACED' as status FROM Info di LEFT OUTER JOIN View_PP pp ON di.ram_file_no = pp.file_no WHERE descrip = 'g' ORDER BY balance DESC
But this does't:
SELECT di.File_No, prevPlacements, balance,'NOT PLACED' as status FROM Info di LEFT OUTER JOIN View_PP pp ON di.ram_file_no = pp.file_no WHERE miscsearch = 'g' ORDER BY balance DESC
What should I be looking for here to understand why this is happening?
We are trying to migrate from sql 2005 to 2012. I am changing one of the implicit join to explicit join. As soon as I change the join, the number of rows returned are fewer than before.
INSERT #RIF_TEMP1 (rf1_row_no,rf1_rif, rf1_key_id_no, rf1_last_date, rf1_start_date) SELECT currow.rf0_row_no, currow.rf0_rif, currow.rf0_key_id_no, prevrow.rf0_start_date, currow.rf0_start_date FROM #RIF_TEMP0 currow LEFT JOIN #RIF_TEMP0 prevrow ON (currow.rf0_row_no = prevrow.rf0_row_no + 1)
[Code] ....
the count returned from both the queries is different.
I am not sure what am I doing wrong. The count of #RIF_TEMP0 is always 32, it never changes, but the variable @countTemp is different for both the queries.
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]
Is there a way to do a super-table join ie two table join with no matching criteria? I am pulling in a sheet from XL and joining to a table in SQLServer. The join should read something like €œfor every row in the sheet I need that row and a code from a table. 100 rows in the sheet merged with 10 codes from the table = 1000 result rows.
This is the simple sql (no join on the tables):
select 1.code, 2.rowdetail from tblcodes 1, tblelements 2
I read that merge joins work a lot faster than hash joins. How would you convert a hash join into a merge join? (Referring to output on Execution Plan diagrams.) THANKS
There is a table called "tblvZipCodes" that contain a zipcode of all cities, area code that are located in that zip code.
The problem I have with the inner join is that there are more than 1 cities in one zipcode code. Is there a way to just return only the 1st row and not return the rest of the rows from the tblvZipCodes in the INNER JOIN query?
Thanks..
Code:
SELECT TOP 100 PERCENT dbo.tblPurchaseRaw.Year, dbo.tblPurchaseRaw.Make, dbo.tblPurchaseRaw.Model, dbo.tblPurchaseRaw.ModelType, dbo.tblPurchaseRaw.Color, dbo.tblvZipCodes.ZIPCode, dbo.tblvZipCodes.City, dbo.tblvZipCodes.County, dbo.tblvZipCodes.State, dbo.tblvZipCodes.AreaCode, dbo.tblvZipCodes.Region, dbo.tblaAccounts.Name, dbo.tblaAccounts.PhoneOne, dbo.tblaAccounts.AccountID, dbo.tblPurchaseRaw.AcceptedID, dbo.tblPurchaseRaw.Series, dbo.tblPurchaseRaw.BodyStyle, dbo.tblaAccounts.WebSite, dbo.tblaAccounts.SalesEmail, dbo.tblPurchaseRaw.EmailTo, dbo.tblPurchaseRaw.PhotoURL, dbo.tblPurchaseRaw.Mileage, dbo.tblPurchaseRaw.RawID, dbo.tblvRegions.Name AS RegionName, dbo.tblPurchaseRaw.VIN, dbo.tblPurchaseRaw.Style, dbo.tblPurchaseRaw.StockDate FROM dbo.tblPurchaseRaw INNER JOIN dbo.tblaAccounts ON dbo.tblPurchaseRaw.AccountID = dbo.tblaAccounts.AccountID INNER JOIN dbo.tblvZipCodes ON dbo.tblPurchaseRaw.ZipCode = dbo.tblvZipCodes.ZIPCode INNER JOIN dbo.tblvRegions ON dbo.tblvZipCodes.Region = dbo.tblvRegions.RegionID WHERE (CONVERT(char, dbo.tblPurchaseRaw.StockDate, 101) <> '01/01/1900') AND (dbo.tblPurchaseRaw.SoldRawID IS NULL) AND (dbo.tblPurchaseRaw.AcceptedID <> - 10) AND (dbo.tblPurchaseRaw.AcceptedID <> - 1) ORDER BY dbo.tblvZipCodes.ZIPCode

I have 2 tables, I will add sample data to them to help me explain...Table1(Fields: A, B)=====1,One2,Two3,ThreeTable2(Fields: A,B)=====2,deux9,neufI want to create a query that will only return data so long as the key(Field A) is on both tables, if not, return nothing. How can I dothis? I am thnking about using a 'JOIN' but not sure how to implementit...i.e: 2 would return data- but 9 would not...any help would be appreciated.
Hi,Just curious. Would you use ANSI style table joining or the 'oldfashion' table joining; especially if performance is the main concern?What I meant is illustrated below:ANSI Styleselect * from a join b on a.id = b.idOld Styleselect * from a, b where a.id = b.idI noticed that in some SQL, the ANSI is much faster but sometimes, theold style looks much better.It's ridiculous to try out both styles to see which is better wheneverwe want to write an SQL statement.Please comment.Thanks in advance.
Hello, everyoneI have one question about the standard join and inner join, which oneis faster and more reliable? Can you recommend me to use? Please,explain me...ThanksChamnap
Where function_code is the function of the area e.g. Auditorium, Classrom, etc, etc. And not all components are available for all functions e.g. Carpeting is available for Classrooms but not Power Plants or Warehouses.
I need to self join the above table to itself on system_code and system_component_code and find out which rows are missing from each side.
A query that I've been banging away at with no success is:
SELECT c1.*, c2.* FROM [dbo].[component_multiplier_table] c1 FULL OUTER JOIN [dbo].[component_multiplier_table] c2 ON (c1.system_component_code = c2.system_component_code) AND (c1.[system_code] = c2.[system_code]) WHERE c1.function_code = '2120' AND c2.[function_code] = '2750' AND (c1.[system_code] IS NULL OR c2.system_code IS NULL);
I added the is null conditions, no joy. I've tried every flavor of outer join w/o success.
Could any T-SQL gurus out there help me figure out how to do this in a set before I start coding
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".
