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;  

how to return records in squence of inner join table?

Hi, I have test database with following script. I am trying to explain my problem with this sample db script. I am creating a temp. table with the ordered column from other table and then using that table to join the other table. If you notice the output of the below select query, the returned rows from first table are in the sequence of insertion not in the sequence of the temp. table. Is there any other way to retrieve rows in the sequence of temp. (joined) table? CREATE TABLE [dbo].[Table_2]( [c1] [int] NULL, [c2] [nvarchar](50) NULL ) ON [PRIMARY] GO INSERT [dbo].[Table_2] ([c1], [c2]) VALUES (1, N'z') INSERT [dbo].[Table_2] ([c1], [c2]) VALUES (2, N'y') INSERT [dbo].[Table_2] ([c1], [c2]) VALUES (3, N'x') INSERT [dbo].[Table_2] ([c1], [c2]) VALUES (4, N'a') INSERT [dbo].[Table_2] ([c1], [c2]) VALUES (5, N'b') INSERT [dbo].[Table_2] ([c1], [c2]) VALUES (6, N'c') CREATE TABLE [dbo].[Table_1]( [c1] [int] NULL, [c2] [nvarchar](50) NULL ) ON [PRIMARY] GO INSERT [dbo].[Table_1] ([c1], [c2]) VALUES (3, N'x') INSERT [dbo].[Table_1] ([c1], [c2]) VALUES (2, N'y') INSERT [dbo].[Table_1] ([c1], [c2]) VALUES (1, N'z') INSERT [dbo].[Table_1] ([c1], [c2]) VALUES (6, N'c') INSERT [dbo].[Table_1] ([c1], [c2]) VALUES (5, N'b') INSERT [dbo].[Table_1] ([c1], [c2]) VALUES (4, N'a&

Cannot get distinct records from a multiple inner join request


Hello everybody,

This is my first post here because this request is giving me serious headache.

What I'm trying to do : This is a small search engine. I ask SQL Server 2008 to return the 20 records I need in a specific page from a larger set of 1000 records. Then I want it to return only distinct records on the key t_ye.numenr (VID).

This returns doubled or tripled records. What am I doing wrong ?



declare @explicitMaximum int <br/>
declare @chosenPage int <br/>
declare @recordsPerPage int <br/>
set @explicitMaximum = 1000 <br/>
set @chosenPage = 1 <br/>
set @recordsPerPage =20; <br/>
WITH X AS (<br/>
SELECT DISTINCT TOP(@explicitMaximum) t_ye.numenr AS VID, <br/>

joining 3 tables and using join to only include records not found in other table



I have 3 tables. I would like to get the number of records in table A that do not have cooresponding co_asset_ids in TABLE C but also need
to be be found in TABLE B and where the asset_id = 3. Said another way: If TABLE A record is in TABLE B and does not find a co_asset_id of 3 as found in table C then show these records.

assetno 4 and 5 are irrelevant but added to fill out the data more.

I know I could do this getting the co_asset_id column into TABLE A and then do some joins between TABLE A and TABLE C and leave TABLE B out, which I have done in the past. I would like to finally know if this can be done by using the 3 tables together in one elegant query.

The result of this query for this example data  would be:

Table A

Table B
assetno    co_asset_id
1              11
2              22
3              33
4              44
5              55

dropdownbox which selects records based on criteria (TODAY, THIS WEEK, THIS MONTH, etc)


I have a dropdownbox which I want to use to search records based on a timescale. The gridview populates results based from that search.

So here is how I want to work this;

If a user selects "today" - a list of records input today are populated. If "this week" is selected, a list of all records added within that week from todays date is populated.

I created a forum on this issue previously but to no avail whatsoever. How do I work around this problem?

Help would be much appreciated
