Lend A Hand With A Query
Aug 23, 2007
I have a question about a query.
I have 2 tables:
As an example I have the following tables (not my real tables)
1) lstParts: Complete list of parts with 2 fields: partID, partName.
2) tblOrders: table of orders with 2 fields: partID, custID
Obviously the partID’s are keys to each other.
What I want is a list of all the records in lstParts that are not in tblOrders for an individual customer. So it might answer, “what parts has this customer NOT ordered?�
What I have so far is close but it is repeating the correct result for each row in tblOrders.
Here is what I have so far
SELECT
p.partID,
p.partName
FROM
lstParts p
LEFT OUTER JOIN tblOrders o
ON p.partID <> o.partID
WHERE
o.custID = ‘123’
Any help would be appreciated
-Thanks

i've been writing an app for my company that has a front end screen in which the user types in all infos needed (ie. name, address, city, state, etc - 82 fields to be exact) then clicks an "add" button, which i put at the bottom, and have that data dumped into a SQL table... the page is then redirected to another page which reads the record just added and displays all the fields that the user submitted...
here is my front end "add" screen code behind written in C#:

Hello !
I came across some interesting issues that solving them will definately help me a lot !
1) Is there a way to insert my database a row, and that it will automatically fill up the datetime column with the local machine time ? (so that I won't have to worry about users local time)
2) I'm trying to synchronize between two data sources - one is my DB and the other is a file. The data in the file should represent the data to be in the DB. However, I don't want to delete all the records and then just insert everything in the file, but to perform Insert, Update or Delete operations according to the file's changes. I managed to do the Insert and Update, but I can't find a solution to a scenario where old data, which is on the DB but not on the file, could be deleted from the DB.
I appreciate the help A LOT !

Hi -
Is there a resource I can go to that lists people who I pay to talk me through stuff like getting SQL Server Express installed, get some sample data input and then get that data into Excel? I just cannot seem to get any help that works for me to learn SQL Server; the books are obtuse, the online help too indirect. Once I get something working I hope to enhance it on my own, but I have been stuck at the start for a very long time. There is stuff for me to do that is not getting done.

I have a table control on a report that is when it is displayed it shows the right side of the report being cut off. If I go to the next page the report displays properly. When I go back to the first page it then displays properly.
How can I get it to display properly the first time it is viewed?

Folks,
On matrix reports, when viewed with IE through the ReportServer URL access page, Matrix reports are getting cut off on the right-hand side to the original size of the report. However, this corrects itself immediately if you toggle any item, or change the zoom level.
What's really confusing is that most of our reports that have expanding functionality work just fine -- there's just a couple that don't. We have spent a couple days trying to figure out what's different with no luck.
EDITED: navigating away from the page by typing another URL in the address bar, and then hitting back, corrects this. The problem is also not present with &rc:Toolbar=false, but with the toolbar on, it's there.
Any ideas?
Thanks so much!

We are running SQL Version 7.0.
I recently set up a simple snapshot replication. After restarting enterprise manager a hand symbol showed up under the database barrel as if a share symbol.
Am I correct in assuming the symbol means replication. Is there a source that explains what the various symbols mean?

I'm trying to run some reports on SQL 2005, but can't even pass the first step of launching the report builder. I have SQL2005 on my local machine, but the report server is installed on a remote server. I launched SQL Business Intelligence Development Studio, which brings Visual studio, but i keep getting a prompt to enter a connection string. How do i get the connection string, or how do i set up my datasource?

I have a problem with ordering and I am hoping that someone is able to help.
In my table I have two fields, "requestdate" and "sentdate", and when I display the records I would like to sort by BOTH fields. I want to do this so that the full query is in order by date.
I tried:
ORDER BY requestdate, sentdate DESC
But obviously all that does is order by requestdate (which is NULL or a date) and than it will order by sentdate.
Can somebody tell me how to order by both as if they were the same field?
Thanks!

Hi, I have created a search page which needs to perform different
search function in same page. I have setuped a sqldatasource then
manual
setup the connection string and command inside the codefile. So the
select command can be various depends on the event. The problem is
all of those setting will be reset after I click on the pageindex in
the girdview control to go to next pages. Since this gridview is linked
with this sqldatasource control, I need to restore the connection
string/command when user choose decide to view next page of data inisde
the
gridview.
I think I must have done something wrong in here becuase it will end up
retrieving the total amount of data when everytime user choose to
view next
or perivous page.
Can someone give me a hand on this ? Thanks

I want to calculate stock aging (qty, cost) based on the on hand quantity.
Currently I am recording only in/out transaction only.

Since as soon as you extend your mdx datasets manually you can no longer switch back into design mode without losing your changes, right?
If that's the case, is there some way to disable design mode completely? i'm finding that the GUI has the tendency to SILENTLY revert the dataset editor back to design mode while I'm busy editing a layout, thereby losing my carefully crafted MDX.

SQL Server 2005 9.0.3161 on Win 2k3 R2
I receive the following error:
"Error: 8624, Severity: 16, State: 1 Internal Query Processor Error: The query processor could not produce a query plan. For more information, contact Customer Support Services."
I have traced this to an insert statement that executes as part of a stored procedure.
INSERT INTO ledger (journal__id, account__id,account_recv_info__id,amount)
VALUES (@journal_id, @acct_id, @acct_recv_id, @amount)
There is also an auto-increment column called id. There are FK contraints on all of the columns ending in "__id". I have found that if I remove the contraint on account__id the procedure will execute without error. None of the other constraints seem to make a difference. Of course I don't want to remove this key because it is important to the database integrity and should not be causing problems, but apparently it confuses the optimizer.
Also, the strange thing is that I can get the procedure to execute without error when I run it directly through management studio, but I receive the error when executing from .NET code or anything using ODBC (Access).

Hey, i've written a query to search a database dependant on variables chosen by user etc etc. Opened up a new sqldatasource, entered the query shown below and went on to the test query page. Entered some test variables, everything works as it should do. Try to get it to show in a datagrid on a webpage - nothing. No data shows.

AFAIK I have configured the source to pick up the dropdownlist value and the textbox value (the text box is autopostback).
Am i not submitting the data correctly? (It worked with a simple query...just not with this one). I have tried a stored procedure which works when testing just not when its live on a webpage.
Please help!

I have the following code.
SELECT _bvSerialMasterFull.SerialNumber, _bvSerialMasterFull.SNStockLink, _bvSerialMasterFull.SNDateLMove, _bvSerialMasterFull.CurrentLoc,
_bvSerialMasterFull.CurrentAccLink, _bvSerialMasterFull.StockCode, _bvSerialMasterFull.CurrentAccount, _bvSerialMasterFull.CurrentLocationDesc,
_bvSerialNumbersFull.SNTxDate, _bvSerialNumbersFull.SNTxReference, _bvSerialNumbersFull.SNTrCodeID, _bvSerialNumbersFull.SNTransType,
_bvSerialNumbersFull.SNWarehouseID, _bvSerialNumbersFull.TransAccount, _bvSerialNumbersFull.TransTypeDesc,
[code]...
However, as you can see, the original select query is run twice and joined together.What I was hoping for is this to be done in the original query without the need to duplicate the original query.

I'm trying to find the command to open up an odbc conection inside sql2005 express. I only have ues of an odbc connector, we're conection to remedy. We will eventually be using stored procedures to extract the data we need from remedy and doing additional data crunching. I'm a foxpro programmer so once I get the correct syntax for making the odbc connector I shold be ok. Also I need a really good advanced book on sql2005. The type of book that would have my odbc answer. I've spent all morning trying to find this information and was unable to.
Thanks in advance

If this was the wrong forum to post this on, please move this question to the correct one. I need this answer soon.

insert into #temptable

-- The 3rd query uses an incorrect column name in a sub-query and succeeds but rows are incorrectly qualified. This is very DANGEROUS!!!
-- The issue exists is in 2008 R2, 2012 and 2014 and is "By Design"
set nocount on
go
if object_id('tempdb.dbo.#t1') IS NOT NULL drop table #t1
if object_id('tempdb.dbo
[code]....
This succeeds when the invalid column name is a valid column name in the outer query. So in this situation the sub-query would fail when run by itself but succeed with an incorrectly applied filter when run as a sub-query. The danger here is that if a SQL Server user runs DML in a production database with such a sub-query which then the results are likely not the expected results with potentially unintended actions applied against the data. how many SQL Server users have had incorrectly applied DML or incorrect query results and don't even know it....?

Hello everybody,
I'm developing a report using the following structure :
declare @sql as nvarchar(4000)
declare @where as nvarchar(2000)
set @sql = 'select ....'
If <conditional1>
begin
set @where = 'some where'
end
If <conditional2>
begin
set @where = 'some where'
end
set @sql = @sql + @where
exec(@sql)
I run it in query analyser and works fine, but when I try to run in Reporting Services, Visual studio stops responding and the cpu reaches 100 %.
I realize that when I cut off the if clauses, then it works at Reporting services.
Does anybody know what is happening?
Why the query works in query analyser and doesn't work in Reporting Service ?
Thanks,
MaurÃcio

For each customer, I want to add all of their telephone numbers to a different column. That is, multiple columns (depending on the number of telephone numbers) for each customer/row. How can I achieve that?
I want my output to be
CUSTOMER ID, FIRST NAME, LAST NAME, TEL1, TEL2, TEL3, ... etc
Each 'Tel' will relate to a one or more records in the PHONES table that is linked back to the customer.
I want to do it using SELECT. Is it possible?

When viewing an estimated query plan for a stored procedure with multiple query statements, two things stand out to me and I wanted to get confirmation if I'm correct.
1. Under <ParameterList><ColumnReference... does the xml attribute "ParameterCompiledValue" represent the value used when the query plan was generated?
<ParameterList>
<ColumnReference Column="@Measure" ParameterCompiledValue="'all'" />
</ParameterList>
</QueryPlan>
</StmtSimple>
2. Does each query statement that makes up the execution plan for the stored procedure have it's own execution plan? And meaning the stored procedure is made up of multiple query plans that could have been generated at a different time to another part of that stored procedure?

I executed the code successfully and I got a box which asked for "Enter the query string".
I typed in the following: EXEC dbo.SalesByCategory @Seafood. I got the following box: Query attempt failed. Must declare the scalar variable "@Seafood". I am learning how to enter the string for the "SQL query programed in the subQuery_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnQuery.Click" (see the code statements listed above). Please help and tell me what I missed and what I should put into the query string to get the information of the "Seafood" category out.
Thanks in advance,
