Query Timout
Mar 11, 2004
OK...i have a query that looks something like what is below and is generated on the fly:
SELECT DISTINCT c.*
FROM SOMETHING c
WHERE ( X IN
(SELECT Y
FROM Z
WHERE ZXY = '1') AND
( X IN
(SELECT Y
FROM Z
WHERE ZXY = '4')OR
( X IN
(SELECT Y
FROM Z
WHERE ZXY = '9')AND
( X IN
(SELECT Y
FROM Z
WHERE ZXY = '7'))
as you can tell something like this will take a long time to process......what is the best way to handle a query like such?....is cursor the way to go......it's driving me nuts!

This error all of a sudden just started happening.

HelloConfig : SQL 2000 on WIN 2000 (IIS 5.0)In my ASP page for some queries i have this error :Microsoft OLE DB Provider for SQL Server error '80040e31'Timeout expiredMy asp page calls a stored procedure passing many parameters.I used the SQL profiler to get the exact stored procedure with allparameters.If i execute stored procedure in the Query Analyzer, it's executesuccessfully in 3-4 seconds.After executing 2-3 times the stored procedure in the Query Analyzer,the error disapear from the ASP Page which runs fine and quickly.My procedure is too long to be detailled here, but to do short, it'slook for the availabilities (the stock) of different products for adesired length of time, with different parameters (color,size,etc..).My main table look like :Day | Id_prod | Provider | Stock | Price1 1 1 2 31 2 1 1 21 1 2 4 51 2 2 0 42 1 1 1 92 2 1 3 72 1 2 1 72 2 2 4 6........366 1 1 4 4366 2 1 1 5366 1 2 2 8366 2 2 0 9The primary key is : day,Provider,Id_prodAnd the main sql statment in my stored procedure :IF @end>@beginINSERT INTO #tmptableSELECT Id_prod,Provider,MIN(stock) FROM mytable WHERE day >= @beginAND day <=@endELSEINSERT INTO #tmptableSELECT Id_prod,Provider,MIN(stock) FROM mytable WHERE day>=@begin ORday<=@end)Note : I use a temporary table to use paging, i just display 10results/pages.The problem only appears if @end<@begin (exemple; which product isavailable from dec 29th to jan 2nd in blue color)Any help would be much appreciated.Thank and happy Christmas.PS:If i set the timeout CommandTimeout = 9999 the problem is resolve butit's not a solution for me.

I'm having an interesting problem. I have a stored proc that executes from SSMS in less than 1 second regardless of the parameters I give it. But when I execute it from my ASP.Net app with certain parameters, it will always timeout. The web app is on my dev machine as is SMSS. The database (SQL Server 2005) is one a different machine a few states away. I have never seen this before ... it's quite aggravating.I found a similar thread where someone stated they fixed this by changing some database settings, but didn't specify what settings.Any help would be greatly appreciated.

Hi,
Our app uses an NT4 SQL 2k box and a Win2k IIS box. To fulfill the text searching requirements we've had to use dynamic SQL (created within a large SP). This query searches about 8000 rows in a flat table (which we create and keep up to date using a scheduled SP which trawls the underlying tables). It's a complicated SP, and can return all 8000 rows (I think we're winning the battle to have this capped though).
When we get about 50 users hitting the app and doing searches simultaneously, performance drops severely (20 secs+ for a query rather than ~2 secs), and we get a lot of errors - which report that:
Source: .Net SqlClient Data ProviderMessage: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.
We also get a lot of Invalid Viewstate errors, which i'm totally baffled by, and the odd IIS Access Denied error - as if authentication (NTLM) is timing out.
Neither the Web not the SQL machines are being hit very hard - the web server in particular is not under any strain whatsoever.
It doesn't appear to be related to connection pooling, from the logged error messages we're getting.
Does anyone have ANY suggestions as to where I should be looking?!

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.

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

-- 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,
Maurício

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 have two tables .. in one (containing user data, lets call it u).The important fields are:u.userName, u.userID (uniqueidentifier) and u.workgroupID (uniqueidentifier)The second table (w) has fieldsw.delegateID (uniqueidentifier), w.workgroupID (uniqueidentifier) The SP takes the delegateID and I want to gather all the people from table u where any of the workgroupID's for that delegate match in w. one delegateID may be tied to multiple workgroupID's. I know I can create a temporary table (@wgs) and do a: INSERT INTO @wgs SELECT workgroupID from w WHERE delegateID = @delegateIDthat creates a result set with all the workgroupID's .. this may be one, none or multipleI then want to get all u.userName, u.userID FROM u WHERE u.workgroupIDThis query works on an individual workgroupID (using another temp table, @users to aggregate the results was my thought, so that's included) INSERT INTO @users SELECT u.userName,u.userID FROM tableU u LEFT JOIN tableW w ON w.workgroupID = u.workgroupID WHERE u.workgroupID = @workGroupIDI'm trying to avoid looping or using a CURSOR for the performance hit (had to kick the development server after one of the cursor attempts yesterday)Essentially what I'm after is: SELECT u.userName,u.userID
FROM tableU u
LEFT JOIN tableW w ON w.workgroupID = u.workgroupID
WHERE u.workgroupID = (SELECT workgroupID from w WHERE delegateID = @delegateID) ... but that syntax does not work and I haven't found another work around yet.TIA!

When I run the following query from Query Analyzer in SQL Serer 2005, I get a message back that says.
Command(s) completed successfully.
What I really need it to do is to display the results of the query. Does anyone know how to do this?

I am trying to run queries against any of the user tables in my MS SQL 7.0 database. I get a message the Query Designer encountered a query error.
We have tried rebooting the SQL Server and I am still getting these messages. Also, the SQL error logs look fine - all database
maintenance are running successfully including the DBCCs which show no errors. Any help would be greatly appreciated as we are to go
into production in a few days.

After manual syncronization it goes under control.
Could anybody explain the relationship between converting error and timed out query?
If this is poor connection's problem how can I increase the query timeout for the process?

Hi Everyone:
*Before* I actually call up Microsoft SQL Customer Support Services and ask them, I wanted to ping other people to see if you have ever ran into this exact error
"Internal Query Processor Error: The query processor could not produce a query plan. For more information, contact Customer Support Services."
I would have searched the forums myself, but at this moment in time, search is broken :(
If anyone has run into this error before, what conditions would exist that this could happen? That is, if I can sniff this out with suggestions from the community, I would be happy to do so.
It is an oddity because if I alter a couple subqueries in the where clause [ i.e., where tab.Col = (select val from tab2 where id='122') ]to not have subqueries [hand coded values], then the t-sql result is fine. It's not as if subqueries are oddities... I've used them when appropriate.
fwiw - Not a newbie t-sql guy. ISV working almost daily with t-sql since MS SQL 2000. I have never seen this message before...at least I don't recall ever seeing it.
Thanks in advance for other suggested examination paths.

Hi all I'm using Sql server 2000 and sometimes i need to run my Queries in Query analizer before using them in my application just to test them...BUT most of the time when i run a query in query-analizer for second time ,query analizer populates the result (records) more quicker then the first time. Apparently it caches the query !!! i don't know but for some reasons i dont't want this , so how can i prevent Query-analizer from doing so?
Thanks in advance. Regards.

I have a vb.net page that I need to display a list of employees who work in a specific office, based on a MatterID passed in a query string. But, I don't know how to get a value returned from one sql statement into a second. Here's what I'm trying to do...
From the QueryString, we know that the MatterID = 4 ( xxx.aspx?MatterID=4)
Knowing that the Matterid=4, I query the database to get the OfficeId for that MID (Select OfficeID from tMatter where Mid=4) ~This returns an OfficeID of 6
So, then I need to do another query to get the employees where OfficeID = 6 (Select EmployeeID from tEmployees where OfficeID = 6)
How do I do these in one query, or how do I use the Calculated Value for the OfficeID in the 2nd statement?

THis is so annoying. I have 3 ADO executes in my program. THe first one creates a view, the second one performs an outer join on that view and returns a result set, the third execute drops the aforementioned view. THe program that is using this is installed on about 200 computers scattered across Germany and Italy, all querying the same MSsql server 7.0. THe queries run quite quick when few users are actively using the program (after hours for example). however in the heat of the day performance goes up and down dramatically with identical queries taking from 1 to 20 seconds to return their result set. Now I initially thought 'bandwidth issue out of our server'. However I noticed that if I take those three queries and run them from the sql server enterprise manager( running on the same computer as the aforementioned program) then the queries run instantly and the data is in my result pane in less than 2 seconds ALWAYS....even when the program is dogging it with 20 second delays before the result set returns. I know it is hanging on the return of the result set as I put a stop after before each ADO execute in order to check which one was eating up my time. Why is there this dichotomy between running the queries from my enterprise manager versus running them from an ADO object. Both are using TCP/IP (no named pipes involved). I havent monkied with the attributes of the ADO result set so they are all set to default.
I have used the sql server profiler to trace these queries and they always run in less than 33 milliseconds. THe duration is also never more than 33 milliseconds. THis stinks of a network resource issue but what always leads me somewhere else is how consistent the performance of the enterprise manager is when it runs the exact same three queries.
Here is my slightly edited connection string
Public Const connection_string = "Provider=SQLOLEDB;Server=000.000.000.000;" & _
"User ID=johndoe;Password=janedoe;Network=dbmssocn;" & _
"database=fidojoe"
Here are the 3 ADO executes:
conn.Execute (sqlstr_create_view)
Set resultset1 = conn.Execute(sqlstr_get_providers_by_DMISID)
conn.Execute (sqlstr_drop_view)
