Any Way To Optimise This Query?
Oct 11, 2005
Hi guys
Is there any way I can run this query faster? Should I take out the ORDER BY
clause? This is supposed to return 17,000 rows and takes around 30 minutes or
so. Is there no way at all to get this result faster?
select r.AttorneyName, r.sitename, r.applicationid, r.clientsurname, r.
clientinitials, r.clientidno, r.grantedamount, r.bankname,
r.accountnumber, r.status, r.grantdate, r.consultantname, r.propertyaddress,
r.erfdescription, r.commenthistory, br.expectedregdate
from bondtrak..rptdetail r
join ebondprd..bankresponse br
on br.applicationid = r.applicationid
where
r.rundate = '20051010'
and r.primarybankind = 'Y'
and r.status = 'granted'
and r.statusdate between '20020101' and '20050930'
and r.businessunit in ('bond choice', 'ppl')
order by r.sitename, r.consultantname, r.statusdate
Thanks for any help.

Hello All,
I have a query that I could use some help with. I would like to see how I could make this query more optimised. I am not hte best at Joins so if someone could help me with this that would be great. Right now its taking about 24-30 secs to run which is a no go. Im wondering if some kind of join would work better?
thank you much

I have these 3 queries - they are the same except each fetches record countsfor one of 3 different record types, nSubsets (type 0), nAssets (type 1) andnImages (type 2). Is there any way I could get all 3 of these (based on theNode.Type integer) with a single query?IF @Error = 0BEGINSELECT @nSubsets = COUNT(*)FROM NodeINNER JOIN AdjacencyON Adjacency.ID_Node = Node.IDWHERE Adjacency.Path LIKE @nodepath + '%'ANDNode.Type = 0SET @Error = @ERRORENDIF @Error = 0BEGINSELECT @nAssets = COUNT(*)FROM NodeINNER JOIN AdjacencyON Adjacency.ID_Node = Node.IDWHERE Adjacency.Path LIKE @nodepath + '%'ANDNode.Type = 1SET @Error = @ERRORENDIF @Error = 0BEGINSELECT @nImages = COUNT(*)FROM NodeINNER JOIN AdjacencyON Adjacency.ID_Node = Node.IDWHERE Adjacency.Path LIKE @nodepath + '%'ANDNode.Type = 2SET @Error = @ERROREND

Hi,
I use this piece of code in a trigger to check if new entered row has unique order number in the given year:
IF EXISTS
(
SELECT COUNT(*)
FROM SPD_Orders
GROUP BY ORD_Year, ORD_Number
HAVING COUNT(*) <> 1
)
RAISERROR('Order with this No exists in given year, 11, 1)
but this code causes deadlocks in my database.
Any suggestions how can I change it to avoid these deadlock?
1. Some constrain? If yes, so how to write it?
2. Index like to enable query optimiser to change execution plan?
CREATE NONCLUSTERED INDEX [_dta_index_SPD_Orders_10_1429580131__K8_K7] ON [dbo].[SPD_Orders]
(
[ORD_Year] ASC,
[ORD_Number] ASC
3. Same index as above but unique and then I will not have to use this trigger, cause database itself with return an error?
4. Any other, the best solution ?
Please help.
Thanks.

Ok I have the following SQL, I have a subquery in the SELECT part but also the same subquery in the WHERE part as well.What I'm trying to do is get all parents that have children OR get all parents with no children OR just get all parents regardless (@HasResponses is a BIT that can be 1, 0 or null). At the same time I want to count the total number of children in the select list, but I'm having to copy the same subquery in the SELECT and WHERE parts which doesn't seem terribly optimal to me (maybe it is, that's why I'm asking). I've tried referencing the column alias in the select list (AS [Responses]) for the where part (@HasResponses = 0 AND [Responses] = 0), but it doesn't seem to work.Is this the most optimal way to do it? Is there a better way? I'm working with SQL Server 2005.SELECTf.FeedbackText AS [Feedback Comment],u.Name AS [Feedback Author],f.CreatedDate AS [Created On],(SELECT COUNT(*)FROM FeedbackResponse frWHERE fr.FeedbackID = f.ID) AS [Responses]FROM Feedback fINNER JOIN [User] u ON f.StaffID = u.StaffIDWHERE f.CreatedDate >= @DateFromAND f.CreatedDate <= @DateToAND(@HasResponses IS NULLOR(@HasResponses = 1 AND(SELECT COUNT(*)FROM FeedbackResponse frWHERE fr.FeedbackID = f.ID) > 0)OR(@HasResponses = 0 AND(SELECT COUNT(*)FROM FeedbackResponse frWHERE fr.FeedbackID = f.ID) = 0))

Hi,
Please can you help me,
I have created an database with 3 indexed (not clustered) fields
key : bytes 100
error : integer
status : bytes 6
I would like to know how to import 3 million or more records quickly.
If I don't index the the fields, the operation takes 3 hours. With indexed fields it takes overnight. Therefore, how can i optomise the import operation from a .txt file.
Thanks and regards.

Hi, please excuse me if this seems like a daft or badly formed question.
A colleage mentioned that when constructing the where clause in a query that it was important what order the criteria were entered. They weren't sure themsleves but the idea was that starting from the bottom of the query you should add the criteria that will have the effect of reducing the data the most and then work 'up' the query back to the from clause.
As a dodgy example, if you have a staff table and you want to run a specific query on all staff over 75 that are male, then:
where gender = "male"
and age >- 75
The reasoning being that the age criteria would reduce the size of the data being worked on more than the gender criteria.
It's been a while since I've had to look at intermediate tables etc but i'm pretty sure this suggestion will not make any difference to the performance of a query.
Thanks,
Matt

Have built tables with stitistical data (very large)in SQL Server 2000
All with 2 fields in common: "Node" and "Datestamp"
At the moment none is indexed.
Tables will have joins added in Business Objects Universe.
How do I know if adding indicis would improve speed of queries?
And if so how are these best added?
Do all tables need indicis or just some?
What does it mean to Optimise the db above adding Index columns?
Can the DB be made optimise itself automatically?
Any prompts very appreciated,

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).

Please help!

-- 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,

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,
Scott Chang

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?
declare @SniierId as uniqueidentifierset @SniierId = '85555560-AD5D-430C-9B97-FB0AC3C7DA1F'declare @SniierAlias as nvarchar(50)declare @AlwaysShowEditButton as bitdeclare @SniierName as nvarchar (128)/* Check access for Sniier */SELECT TOP 1 @SniierName = Sniiers.SniierName, @SniierAlias = Sniiers.SniierAlias, @AlwaysShowEditButton = Sniiers.AlwaysShowEditButtonFROM SniiersWHERE Sniiers.SniierId=@SniierId

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.

Message: Error converting data type nvarchar to numeric.
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?
