Get all data - LEFT OUTER JOIN with condition

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;  

I can do this in other ways, but am looking for the "LINQ" way of doing this: Table1: People (PersonId,SchoolId)Table2: AssignedPeople (PersonId,SchoolId,RoomId) I want to select the people in Table1 within a particular SchoolId that are not in the assignedPeople table (in a particular Room).  The SQL is: select p.* from people p left outer join assignedpeople ap on p.PersonId=ap.Person and p.SchoolId=ap.SchoolIdand ap.RoomId=@roomId where p.SchoolId=@SchoolId and ap.PersonId is null I tried this LINQ (VB,NET):dim SchoolID as guid=...dim RoomID as guid=... (from p in dc.people where p.SchoolId=SchoolIdgroup join ap in dc.AssignedPeopleon p.PersonId equals ap.PersonId and p.SchoolId equals ap.SchoolId into groupfrom g in group.DefaultIfEmptywhere g.RoomID = nothing) but I can't get the ap.RoomId=@roomId part into the right place, should be something like:group join (from ap in dc.AssignedPeople where ap.RoomId=RoomId) Any help would be appreciated,Reuven

HiI have found quite a bit of info on the net, but I can't get it to work. Here's the normal SQL query:SELECT cl.ID AS ClientID, cl.Name, cl.Surname, CLC1.PHONECODE + ' ' + CLC1.PHONENUMBER AS WorkNum, CLC2.PHONECODE + ' ' + CLC2.PHONENUMBER AS HomeNum, CLC3.PHONECODE + ' ' + CLC3.PHONENUMBER AS CellNum, CLC1.PREFERRED AS WorkNumPref, CLC2.PREFERRED AS HomeNumPref, CLC3.PREFERRED AS CellNumPref, veh.ID AS VehicleID, veh.MAKE, veh.MODEL, veh.YEAR, veh.REGNO, ws.ID AS WorkshopID, ws.JOBTYPE, ws.SERVICEADVISOR, ws.TIMEFINISHED, ws.TECHNICIAN, fs.ID as FollowupID, fs.TYPE, fs.DESCRIPTION, fs.SCHEDULEDATE, fs.WRONGNUMBERFLAG FROM CLIENTS AS cl LEFT OUTER JOIN CLIENTCONTACTNUMBERS AS CLC1 ON cl.ID = CLC1.CLIENTID AND CLC1.TYPE = 'W' LEFT OUTER JOIN CLIENTCONTACTNUMBERS AS CLC2 ON cl.ID = CLC2.CLIENTID AND CLC2.TYPE = 'H' LEFT OUTER JOIN CLIENTCONTACTNUMBERS AS CLC3 ON cl.ID = CLC3.CLIENTID AND CLC3.TYPE = 'C' INNER JOIN CLIENTVEHICLES AS clveh ON cl.ID = clveh.CLIENTID INNER JOIN VEHICLES AS veh ON clveh.VEHICLEID = veh.ID INNER JOIN WSBOOKINGS AS ws ON clveh.ID = ws.CLIENTVEHICLEID INNER JOIN FOLLOWUPSCHEDULE AS fs ON fs.WSBOOKINGID = ws.ID WHERE fs.ID = 2 There is a multiple join between CLIENTS and CLIENTCONTACTNUMBERS so it would return a single row of data. If you were to do a normal join on CLIENTS and C

 Hi   I try to get this exsisting linq query to use a left outer join without success, can anyone show me how its supposed to be?   Dim product = (From f In db.tbl_Formats _ Join p In db.tbl_Products On f.FormatID Equals p.FormatID Where p.NodeId = iNodeID _ Select p, f.FormatName).SingleOrDefault   The FormatID is not always present and I therefore need a left outer join on the Formats table.   Best Regards

select A.names,B.address,C.age from A left outer join B on A.names=B.names left outer join C on C.age=B.age

select A.names,B.address,C.age from A left outer join B on A.names=B.names left outer join C on C.names=B.names

select A.names,B.address,C.age from A left outer join B on A.names=B.names left outer join C on C.address=B.address

select A.names,B.address,C.age from A left outer join B on A.names=B.names left outer join C on A.age=B.ages

how does this work, all the data in the tables A,B & C are the same, is the last query valid,bocz 'on' condition is not for the table of the left outer join

Hi All,

I have one confusion. I have been told that if I am joining the two tables using the left outer join then I cannot use columns from the right side table  in where condition, otherwise it will act as a inner join.

e.g. select tr.* from trans tr LEFT OUTER JOIN detail d on tr.hprop = d.hprop where tr.hmy between 1 and 100 and d.hprop = 2 ....(will this act as inner join as I have mentioned d.hprop =2 in where condition?)

Is it correct? anf if yes then how?

 Please Help.

Thanks!

Hello,
  how would I join fields together?

           return (from c in storedb.Product_Categories

                         where c.Category_Name.Contains(searchText)
                         orderby c.Category_Name
                         select new {
                                    c.Cat_GUID,
                                    c.Category_Key && " ;" && c.Category_Name // HOW CAN I DO THIS.....
                          

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.

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/

I have a table called Leaves. Fields are,LeaveIDPersonIDActingPersonIDIn Person's table, I have,PersonalIDEmployeeCodePersonNameNow, in the datagrid, I need to show,PersonEmployeeCodePersonNameActingPersonEmployeeCodeActingPersonNameNow, I know how to write the SQL Join to get the data populated. But, the problem is, in some cases, there won't be any acting person. In which case, I need to display data, PersonEmployeeCode = 0001 PersonName = John ActingPersonEmployeeCode = - ActingPersonName = No acting Person Now, I am stuck here. How do I do a conditional join statement?Please help! RegardsKush

Hi, Here is the situation: I have a query with the following format:       Select a.*, b.* from (select col1, col2 from tbl1 t1 left join tbl2 t2 on t1.x = t2.x where t1.colSmallDateTime= MAX(t.ColDateTime)) a                     LEFT OUTER JOIN (select col1, col2 from tbl1 t1 left join tbl2 t2 on t1.x = t2.x where t1.colSmallDateTime= MIN(t.ColDateTime)) b                     ON (a.y = b.y) When i tun this query i get the following error:            Msg 298, Level 16, State 1, Line 1            The conversion from datetime data type to smalldatetime data type resulted in a smalldatetime overflow error. Does anyone have any idea why i am getting this error? Thank in advance for your help!  

Hello! We found a problem when migrating from SQL Server 2005 to SQL Server 2008. SQL-statements like   SELECT <table1>.<fields>, <table2>.<fields>, <table3>.<fields> FROM <table1> JOIN <table2> ON <table2>.<field> = <table1>.<field> LEFT JOIN <table3> ON <table3>.<field> = <table1>.<field> WHERE (<table2>.<field> = 2 AND <table2>.<another_field> = 'some_text' OR <table3>.<field> = 2 AND <table3>.<another_field> = 'some_text')   give different results on 2005 / 2008. On 2008 I get lots of exessive rows which have NULLs instead of the values required in the WHERE-term. Changing the Compability Level does nothing. It also doesn't matter from where the query is executed (direct via ODBC, in a view or from the Enterprise Manager). 2005/2008 also use different execution plans. (Btw: how can I make an screenshot of a EP larger than the screen?)   After some hours I drilled it down to the existence of a index! By deleting or deactivating the index 2008 gives the correct results like the 2005 did, after activating the index I get these exessive NULL-rows again!   Anyone else ran into this problem? Any tips (dropping all indexes in a 25+ GB DB is NOT an option :-) ?   Thanks in advance! Holger WellenkötterMCTS SQL 2005

I'm using the Merge Join to join several different incoming flows into one flow.  I've configured the joins to use a Full Outer Join because I need all records from all sources. In the case of a no-match, I want the component to keep the values of join key fields instead of setting them to NULL.  How can I achieve that?  (Activating the checkbox doesn't help, because that adds a new field to the output instead of re-using the existing one.)

Hi, I'm having an issue with an outer join due to my data structure. I have a view and table and I need to join them so that I get all the records from the table and the associated results from the view. The view structure is: Total | cID | cName | lID | lName 50       1       2 GB      1      Stock Room 100     2       4 GB      1      Stock Room The table structure is: cID | cName 1        2 GB 2        4 GB 3        8 GB 4       16 GB The result i'm looking for should therefore look like this returning all rows from the table, matching rows from the view and NULL for non-matching rows: cName | Total 2 GB       50 4 GB       100 8 GB       NULL 16 GB     NULL Probably something very basic i've missed.

  Hey, While working SSIS in 2008 we have encountering some weird problems with Merge, Merge Join and Condition Spilt transformations, here are the details... Condition Split and Merge Join and Condition Split: Please check the below diagram(not really just tried) for the complete details. Just FYI data is in sorted order   condition Split -> 420000      | 18                                                          | 419982  Merge Join(left)  -- src1(6000)      |10  Condition Split      |9     |1   the merge join transformation is not returning the complete 18 rows to the next transformation that's why we are missing 8 rows. But if we adds a sort transformation (getting warning as data is already sorted) before merge then complete 18 rows were passing to the condition split. Also tried modifing the source query just to return 18 rows then also it was passing the 18 rows to next trasnformation except with full load.       Merge: We have two sorted data sources and first one has 40000 records and second source have 12000 records and after the Merge transformation we have Condition Split transfor

Hi all In processes of upgrading SQL Server 2000 to SQL Server 2008 I held up with one issue I am not a good pragrammer If some helps me how to modify this query,realy it help for me. "Outer join operators *= and =* are not supported in 90 or later compatibility modes" Here this query SELECT Brnd.Name, Dev.Devype FROM Prd,PrdRel, Rel, RelVer, DevSoft, DevCla, Dev, Brnd,OVer WHERE Prd.ID = PrdRel. Product AND Rel.ID = PrdRel.Release AND RelVer.Release = Rel.ID AND DevSofte.ReleaseVersion = RelVer.ID AND DevSoft.DeviceClass = DevCla.ID AND DevCla.ID = Dev.DeviceClass AND Brnd.ID = Dev.Brand AND OVer.ID =* Dev.OSVersion AND RelVer.Latest = 'Y' AND Prd.ID = @Product AND Rel.OS IN (@OS) Please some help me how to code  to come out from the problem. your help going to be greate for me.  SNIVAS

Good afternoon, I'm experiencing quite strange issue with our T-SQL code. We have inline table-valued function which is using full outer join on 1 = 1. The reason why we do it this way is - we need to combine one row from 2 different result sets either of them can have either 0 or 1 row. The strange thing, that if we have the situation when both row-sets are empty, function does not return the row (as expected). Although, select which uses this function with cross apply "uses" the result from the previous row. Below is the simplified example. First select with ID = 2 predicate does not return any rows. Although if I remove this filter, it re-uses Value2 from the previous row. create FUNCTION dbo.Func(@Id int) RETURNS TABLE AS RETURN ( with CTE1(Value1) as ( select 'Value1' where @ID = 1 ) ,CTE2(Value2) as ( select 'Value2' from CTE1 ) select CTE1.Value1, CTE2.Value2 from CTE1 full outer join CTE2 on 1 = 1 ) go select * from dbo.Func(2) go create table dbo.TestTable ( ID int not null ) go insert into dbo.TestTable values(1), (2) go select t.ID, f.Value1, f.Value2 from dbo.TestTable t cross apply dbo.Func(t.ID) f where t.ID = 2 go select t.ID, f.Value1, f.Value2 from dbo.TestTable t cross apply dbo.Func(t.ID) f order by t.id go Our SQL version is: Microsoft SQL Server 2008 (SP1) - 10.0.2531.0 (X64) &nb
