Annoying Inner Join Problem
Dec 13, 2006
Greetings SSIS friends,
I have the following problem in SSIS and it's driving me nuts!!!!!
My situation is as follows :
Data Source 1 & Data Source 2are joined using a merge join. This bit works fine.
The output of the above join is then joined to a third data source but this time, I only get 63 rows coming through instead of 77097 even though the join key in the second merge join component is the same as the first one!!!
I thought I was going mad so I decided to see if the same problem occurs if I was to do this with T-SQL. I created 3 temporary tables for each of my data sources.
I did an inner join between tmpTable_Source1 and tmpTable_Source2, I then stored the result in tempTable4
The final inner join was performed between tempTable4 and tempTable3 and the result produced 77097 and not 63 rows.
What the hell is SSIS playing at?! The merge keys I used in T-SQL is the same one I used in my SSIS package!!!!

I have a very confusing/complicated query that I am trying to run and getting not the results that i want.
Essentially I have three tables (t1, t2, t3) and I want to select data from two of them, but there are conditions on the data where I need fields to match across pairs of tables.
When I run my select query I am getting far too many records - it's giving me all possible combinations, instead of the proper combinations that I want.
Select t1.*, t3.field2, t3.field3
FROM, t1, t2, t3WHERE t2.field4=t3.field4 AND t1.field5=x AND t1.field6=t2.field6
I suspect there is plenty wrong with this query - where should I start correcting it?

Hey guys, I bet you didn't guess it but I'm posting here because i need help :P
What I'm trying to do is create a procdure that will run a task on the first Working day of the week.
Normally monday but then theres public holidays etc etc.
on a normal week the task runs monday, on public holiday weeks it is tuesday, and christmas even pushs it back to wednesday.
so far im using the dts designer to do this
What I have is:
a table with the last run date(not sure I even need this now)
a table with a list of public holidays(date) along with a year column
a sql statment getting the last ran date and storing it into a global variable glastrundate
a activex vbscript getting the current year, which is then stored into a globalvariable(gcurrentyear)
then gcurrentyear is then used in a select statement to get the public holidays that are in that year, which are then stored to a rowset (gpubdays)
(select pubdays from tbl_pubdays where pubyear = ?)
Now the problem, I am trying to use another axtivex script to check the current date against each row in the global gpubdays. well really I just can't get the for each loop to work, was trying to use it like:
for each row(or pubday) in gpubdays
if day = today then
task fails and will not run the rest of the procedure
end if
next
sorry if it isnt very clear, still kinda new to SQL server
thanks if you help ^_^
ps. please dont go writing all the code for me, just a nudge in the general right direction

I know I shouldn't rely on sysdepends because it's got all sorts of problems with broken dependency chains, etc. But it's better than nothing for finding dependencies, short of rolling your own t-sql parser. So I use sysdepends anyway, with all its faults. I just don't rely on it. anyway, to the point, just an fyi really:
Here's something about sysdepends discovered today that annoys me. If you introduce a dependency of a proc on a table by selecting from the table in the proc, the sql parser discovers this and dutifully adds a row to sysdepends. Very well. But if you do the same select into a temp table, sysdepends doesn't pick up the dependency! Here's what I mean:
use master
go
drop database test_sysdepends
go
create database test_sysdepends
go
use test_sysdepends
go
create table MyTable01 (id int)
go
create proc MyProc01
as
select id from MyTable01
go
create proc MyProc02
as
create table #t (id int)
-- comment this next line out and the dependency is picked up.
-- but as long as we insert into the temp table, we don't pick it up... :(
insert into #t
select id from MyTable01
select id from #t
go
select
so2.name as parent
,so1.name as dependent
from sysdepends d
join sysobjects so1 on d.id=so1.id
join sysobjects so2 on d.depid=so2.id
go
results:
parent dependent
--------- ---------
MyTable01 MyProc01
i am seeing this on 2005 sp1, also on 2000 (msde)
grrr...

Well all bugs are annoying, but this one is particularly annoying because it kills the BIDS session with consequent loss of all changes made since the last save.
Click on a control flow task. Position the cursor so that it changes to the 4-way pointer. Drag the task a little bit. The UI locks up, and then BIDS disappears.
I can't repro this on demand, but it has happened about 6 times in the past month. Anyone else seen this one?

Can someone please help me.
I am running a 'simple' stored procedure from the Query Analyser (command - FindCustomer L18239, [ ]) which should return a name from a customer table from the input id. It does return the name but I keep getting the message

I'm recieving the following error:
The SQL Server System Configuration Checker cannot be executed due to WMI configuration on the machine 'machine information' Error: 2147749896 (0x80041008).
I've researched the error and found out some people were running batch scripts to reinstall wmi, but none of them worked for me. One of them I gave up on after thirty minutes and it wasn't doing anything.
Please give some suggestions on how I can resolve this issue.

Hello,
I recently migrated from 2000 to 2005 database. On the new server, I kept getting this type of error message when there is some sort of join involved and they are not complex join either.
Error - "A severe error occurred on the current command. The results, if any, should be discarded."
ie
select A.Cookie1, A.Cookie2
into BookersLookers_Cookie
from BookersLookers_DataSet A
LEFT JOIN ActionSetup B on A.ActionID = B.ActionID
group by A.Cookie1, A.Cookie2
Is there something in the code where I could prevent this error from happening?
Any insight is appreciated,
-Lawrence

Hi,
Pbbly most of you know this:
Intra-query parallelism caused your server command (process ID #57) to deadlock. Rerun the query without intra-query parallelism by using the query hint option (maxdop 1).
I've seen MS KnowledgeBase for that (http://support.microsoft.com/default.aspx?scid=kb;EN-US;837983)
But I have some probs with it:
1. I don't have permissions for this kind of queries
"USE master
EXEC sp_configure 'show advanced option', '1'
RECONFIGURE WITH OVERRIDE
GO"
2. I don't know what is an "intra-query parallelism"...
I'm attaching the query I use. The query runs OK for some parameters but gets this error msg on other parameters.
I'm using a single CPU on 2003 STD Edition.
Query:
create table #mytemp_table
(client_id int not null, commission_value int null)
insert into #mytemp_table (client_id, commission_value)
select client_id, sum(transfer_value) from users_transfers where transfer_type in (1,3) and is_paid = 1 group by client_id
select
u.name [Vendor],
u.email,
sum(cost) as Payment,

ua.name [Agent],

I have SQL Server Manager 8.00.2039 installed because I have one program(app) installed that requires it be installed. For the first littlewhile when I had SQL server installed it would only show up in thetaskmanager tray, now MOST of the time, it shows up as a popup on mydesktop and also in my task tray when I first start XP (SP2). It staysthere until I close it. Is there a way to prevent the SQL from poppingup?Thanks

I am having a problem connecting to my SQL Server 2005 database at the same time with SQL Management Studio Express and from the website at the same time.
Everytime I want to view any pages in my site that access the database, I have to close management studio and restart the server for some reason or i get a failed login error message.
Is it NOT possible to work on the database at the same time as viewing pages in the website that access the database?
This freaking error is realy starting to bug me.
I sure hope that there is a work around or something for this.

Hello, I am having problems inserting information into my DB.
First is the code for the insert
Sub AddCollector(Sender As Object, E As EventArgs)
Message.InnerHtml = ""
If (Page.IsValid)
Dim ConnectionString As String = "server='(local)'; trusted_connection=true; database='MyCollection'"
Dim myConnection As New SqlConnection(ConnectionString)
Dim myCommand As SqlCommand
Dim InsertCmd As String = "insert into Collectors (CollectorID, Name, EmailAddress, Password, Information) values (@CollectorID, @Name, @Email, @Password, @Information)"
myCommand = New SqlCommand(InsertCmd, myConnection)
myCommand.Connection.Open()
myCommand.Parameters.Add(New SqlParameter("@CollectorID", SqlDbType.NVarChar, 50))
myCommand.Parameters("@CollectorID").Value = CollectorID.Text
myCommand.Parameters.Add(New SqlParameter("@Name", SqlDbType.NVarChar, 50))
myCommand.Parameters("@Name").Value = Name.Text
myCommand.Parameters.Add(New SqlParameter("@Email", SqlDbType.NVarChar, 50))
myCommand.Parameters("@Email").Value = EmailAddress.Text
myCommand.Parameters.Add(New SqlParameter("@Password", SqlDbType.NVarChar, 50))
myCommand.Parameters("@Password").Value = Password.Text
myCommand.Parameters.Add(New SqlParameter("@Information", SqlDbType.NVarChar, 3000))
myCommand.Parameters("@Information").Value = Information.Text
Try
myCommand.ExecuteNonQuery()
Message.InnerHtml = "Record Added<br>"
Catch Exp As SQLException
If Exp.Number = 2627
Message.InnerHtml = "ERROR: A record already exists with the same primary key"
Else
Message.InnerHtml = "ERROR: Could not add record"
End If
Message.Style("color") = "red"
End Try
myCommand.Connection.Close()
End If
End Sub
No matter what I get a "Could not add record" message
Even substituting the insert command string with my stored procedure I would get the same thing
Stored Procedure:
CREATE Procedure CollectorAdd
(
@Name nvarchar(50),
@Email nvarchar(50),
@Password nvarchar(50),
@Information nvarchar(3000),
@CustomerID int OUTPUT
)
AS
INSERT Collectors
(
Name,
EMailAddress,
Password,
Information
)
VALUES
(
@Name,
@Email,
@Password,
@Information
)
GO
Can anyone see any problems with this code? It looks good to me but I get the same message always.
Thanks

Originally I started using SQL Server Management Studio on the server directly. When I would right click on a view->edit I would essentially get a Alter Script of the view. Clicking on view-> design would open the query editor.
However I decided to connect to the server from my desktop instead using a local installation of SQL Server Management Studio. Now when I right click on a view I only get the modify option which opens the Query Editor and not the actual code that can be scripted. I know I can just right click->script view as->alter to to get similar results. I just can't seem to find any options to change this functionality. Does anybody know how to change this or is this a limitation of a desktop installaion?
Thanks

So on my local server I have a username CWI. I have my main DB: CW.
CWI is the owner of 5 schemas on CW, and everything works great.
---
I now go and create a new DataBase called CWTest. I want to now add the user CWI to the security section of CWTest (The same way I did it in 2000).
However, now I get the error message:
"The login already has an account under a different user name."
When I created my DataBase, IT had the default user, but now I want to add another user so I can create my schemas.
---
On our live servers, we will have 100-300 Databases all using the same useraccount as the "God Mode" user.
Any advice?

Hello, does anyone hate the new interface where you
manage the Table Relationships, Indexes, and etc?
I hate it a lot for these reasons.
1) Dialog window cannot be resized (really really annoying)
2) The Table-Relationship configuration dialog window is not as convenient to use as SQL Server 2000 Enterprise Manager.
I hope this is the correct place to provide feedback and
I hope this will get modified a bit in the next service pack (or) update....

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.

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.

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?

I'm using SQL Server 2005.
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?
Thanks,
john

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.
Below is my Implict join query
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 , #RIF_TEMP0 prevrow
[Code] ....
and below is explict join query
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
But how to do this in SSIS?
Thanks - Ken

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.)
