Logical Join vs Physical Join ?

Posted By:      Posted Date: October 06, 2010    Points: 0   Category :Sql Server

HI All ,

1) Can any one please post a sample when and where hash join , Merge Join and Nested Loop joins come into picture ?

2) Logical joins : Inner Join , Outer , Full , Cross joins

    Physical Joins : Merge ,Hash , Nested Loop Joins

What are the differences between Logical and Physical joins ?

When should we go with Physical joins ?

It would really be appreciated if any one can post few samples .

Thanks in Advance .

Cannot properly join lists in SPD 2007


Ok, I have been reading all sorts of posts and such for about a week and still have no come up with any concrete answers.


I cannot properly join lists in SP 07. I say properly because I never get the option to select a field to associate one with the other. 

I select "Create new linked data source" from Data Source Library; Pane opens; Left Click "Configure Linked Data Source"; Add 4 to 5 lists from "Current Site"; Select Next; Select Join option but Next is greyed out. Is this supposed to be greyed out because they are lists? Can lists be joined? I see alot of examples on joining databases and excel pages but not too many on lists.

If I select next from the last point, open the linked sources and select my newly created linked source and click to show data, I can see all of the information in there. Problem is I don't believe the lists are really joined by anything since I never received an option for it. 

I also have been reading up on joined subviews but I never receive an option for  joined subview. Is the joined subview the way to go for lists? If so how?


I know these boards are fairly active and any information or help would be greatly appreciated.

insert into in combination with inner join


Hi All,

I have my data split in 3 tables for cascading dropdownlists.

How can I make an update statement of this select statement?

SELECT distinct BIER.Naam as naam1, BIER_L2.L2_Naam as naam2, BIER_L3.L3_Naam as naam3
	from BIER, BIER_L2, BIER_L3
	where BIER_L2.L2_ID = BIER.L2_ID and BIER_L2.L3_ID = BIER_L3.L3_ID 



Join 2 flat file data flows - retain unmatched rows

I have two data flows from two separate flat files. They may contain matching IDs (account number), in this case specific data from each flow should be used to create one row. When there is no match, the rows would stand on their own. At the end of the flow, I need both flows combined into one flow, with one record for each key record (account number). If I were able to use a look-up, I could easily union the no-match data flow back into the match data flow and have the desired result. I cannot use a look-up, since the source is flat files, but this is exactly the functionality I am trying to achieve. Solutions I want to avoid: staging tables, and cache transformations. Any ideas are appreciated.

repeating merge joins using full outer join - should be possible without sort, but cannot get the co

Hello,   I am trying to combine several source tables with Merge Join.  For the Moment I have three source tables all already sorted in the source query and the is sorted property with the correct keys set. (its an aggregate query with group by and sort by the key columns) Then I do a merge join between two of the tables - with a full outer join. Then I just want to do another merge join with the output of the next result. but as the merge join do not combine the key columns into one column I need to add a derived column which substitute null values on the left side of the join with values from the right side of the join. The second merge then says only the left columns of the first merge join is sorted, but not the comined columns. If i Replace with a derived column the left side primary key columsn with the combinded key columns the next merge join says the input is not sorrted? But the output must be sorted. So how do I get the next merge join working without the ssis sort transformation? the data is sorted, but the component does not recognize the sorted data? I do not want to use (can use) the sort because there are flowing >= 500 Mio. records through the pipeline. Any help appreciated.   Hanneshttp://www.hmayer.net/

problem with inner join

Hi, I'm trying to create an sql query with multiple inner joins, but I can't manage this. I have 3 tables (bookings, accountplan, costs), where the data come from. In accountplan are hold the accounts, in costs the cost codes and their names, in bookings the booked events. Based on a booking event, I need the account name, the name of the cost code and all data from bookings (I need the cred account name too, but I can't figure out yet, how I can get this) I tried this: "SELECT bookings.*, accountplan.accountname, costs.costname FROM bookings INNER JOIN accountplan ON bookings.debaccount=accountplan.account INNER JOIN costs ON bookings.costcode=costs.costcode" It is here a where clause too, but I tested it, it's ok. The above query results no rows. If I remove the costs table and the inner join with it, it works. What am I missing?

Left Outer Join fails to return all records

I have a table tblDrop that contains 1067 records for 8/31/2010 and a table tblSoftcount that has 739 records, some with bad serial numbers. I need to match all of the records in tblDrop with those in tblSoftcount. I have a query using Left outer join that has worked for the duration of the application, but has recently stopped returing the full set of records from tblDrop. We have not changed the SQL versions on the server (compatibility level 2005). Here is the query: SELECT   v.SlotNum_ID, s.SlotNum_ID, v.PTNumber, s.PTNumber, v.DropBillAmount AS [Drop], v.ReportDate, v.DateValue     FROM tbl_Drop v LEFT OUTER JOIN tblSoftCount s ON v.SlotNum_ID = s.SlotNum_ID AND v.ReportDate = s.ReportDate WHERE   s.ReportDate = '8/31/2010' AND v.DropBillAmount <> 0 AND s.Slotnum_ID IS NULL;
