I think this is very silly question
but It is hard for me :eek:
SELECT email, host FROM WAITING_AUTH WHERE email NOT IN
(SELECT email FROM MEMBER)
AND host NOT IN (SELECT host FROM MEMBER)
thanks~ Have a nice weekend
I have written a query which fetches data from a table with huge amount of data. This query is actually being used in a stored-procedure and it takes a lot of time, hence slows down my SP.
Here is the query that I'm builiding in the stored-procedure:
-------------------------------------------------------------
SET @selectLeadsInPeriodString = ' SELECT LM_Dealer, LM_Brand, SUM(LM_ImpressionCount)
FROM LM_ImpressionCount_Dealer'
IF(@timeCriterion IS NULL OR LTRIM(RTRIM(@timeCriterion)) = '' OR LTRIM(RTRIM(@timeCriterion)) = 'NULL')
SET @selectLeadsInPeriodString = @selectLeadsInPeriodString +
' WHERE (CONVERT(varchar,[LM_ImpressionCount_Dealer].[LM_ImpressionDate],102) >= ''' +
CONVERT(varchar,@startDateTime,102) +
''' AND CONVERT(varchar,[LM_ImpressionCount_Dealer].[LM_ImpressionDate],102) <= ''' +
CONVERT(varchar,@endDateTime,102) + ''')'
ELSE IF(@timeCriterion = 'CurrentMonth')
SET @selectLeadsInPeriodString = @selectLeadsInPeriodString +
' WHERE MONTH([LM_ImpressionCount_Dealer].[LM_ImpressionDate]) = MONTH(GETDATE())'
ELSE IF(@timeCriterion = 'PreviousMonth')
SET @selectLeadsInPeriodString = @selectLeadsInPeriodString +
' WHERE MONTH([LM_ImpressionCount_Dealer].[LM_ImpressionDate]) = MONTH(GETDATE()) - 1'
ELSE IF(@timeCriterion = 'YearToDate')
SET @selectLeadsInPeriodString = @selectLeadsInPeriodString +
' WHERE ([LM_ImpressionCount_Dealer].[LM_ImpressionDate] >= cast((''1/1/''+cast(year(getdate()) AS varchar(4))) AS datetime)
AND CONVERT(varchar,[LM_ImpressionCount_Dealer].[LM_ImpressionDate],102) <= CONVERT(varchar,GETDATE(),102))'
IF(@brand IS NOT NULL AND LTRIM(RTRIM(@brand)) <> '')
SET @selectLeadsInPeriodString = @selectLeadsInPeriodString +
' AND [LM_ImpressionCount_Dealer].[LM_Brand] = ''' + @brand + ''''
SET @selectLeadsInPeriodString = @selectLeadsInPeriodString + ' GROUP BY LM_Dealer, LM_Brand'
The variables used in the query formation above are passed as input parameters to the SP.
The table being queried has columns 'LM_Dealer', 'LM_Brand', 'LM_ImpressionCount' and 'LM_ImpressionDate'.
Also, the table has a non-clustered index on the column LM_ImpressionDate.
With all this information, can anyone suggest as to how I can optimize the query above.
Thanks in advance.

hi,I have a problem asked by one of my senior person and finding theanswer .What is the step by step procedure for tune a large sql query.OR how do we tune a large SQL query with somany joins
View 6 Replies View Relatedhi here has a question for the mssql,
a problem occurs when i run a large database, the running speed is very slow.
for example, if i want to seek the record of 1500 employees with 15 per person(average) within 1 year(12 months), that mean i have to find record for 1500 * 15 * 12 time.
so, could i find a way to solve this problem? is this call tune the sql server/index/view?
what different of tune the sql server with index and view?

Hi,
I have SQL desktop version installed and for the last few days it has really slowed down. I have ran many anti-virus etc. and all is okay on that front.
Any tips regarding how I can tune things up? What should I look for and how do I go about it. Deleting LOG etc. etc???
Please guide.
Thanks.
ENVIRONMENT:
I have SQL Server6.5 running under a dedicated NT Server. NT configuration includes dual pentium 200Mhz processors, 256MB RAM and RAID system.
The Database size is 1GB with actual data size about 500MB.
PROBLEM:
I have an application which uses lots of joins to get the results. My select query is running too slow even when I run it on the server.
I updated the statistics and rebuild all the indexes on the tables used by the query.
Any suggestions on using SQL Trace and tuning the server/database are welcome.

I've create a bunch of views to expose a logical model of the underlying database of an application server.
To enforce the security control, I've also created a CLR UDF to call the application server's API for security check and audit log.
For example, we have a table, tblSecret, and the view, vwSecret, is,
SELECT
Id,
ParentId,
Description,
SecretData
FROM tblSecret
WHERE udfExpensiveApiCall(Id) = 1
The udfExpensiveApiCall will return 1 if the current user is allowed to access the SecretData else 0. The CLR UDF call is very expensive in terms of execution time and resources required.
Currently, there are millions rows in the tblSecret.
My objective is to tune the view such that when the view is JOINed, the udfExpensiveApiCall will be called the least number of time.
SELECT
ParentId,
SecertData
FROM vwParent
LEFT JOIN vwSecret ON vwSecret.ParentId = vwParent.ParentId
WHERE vwParent.StartDate > '1/1/2008'
AND vwSecret.Description LIKE '%WHATEVER%'
Is there any way to specify the execution cost of the CLR UDF, udfExpensiveApiCall, such that the execution plan will call the UDF while it is absolutely necessary?
Is there any query hint will help?
Any recommendation?
Thanks,
Simon Chan

I want to tune the indexes on my database and I am trying to use the SQL Server Profiler to collect data for the Index tuning wizard to analyze. My question is what do I need to trace with the profiler so that the Index tuning wizard can work? I am looking at the trace properties in Profiler at the Events, Data Columns, and Filters tabs but I have no idea of what I need to capture.
Thanks in advance.

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).

how do I get the variables in the cursor, set statement, to NOT update the temp table with the value of the variable ? I want it to pull a date, not the column name stored in the variable...
create table #temptable (columname varchar(150), columnheader varchar(150), earliestdate varchar(120), mostrecentdate varchar(120))
insert into #temptable
SELECT ColumnName, headername, '', '' FROM eddsdbo.[ArtifactViewField] WHERE ItemListType = 'DateTime' AND ArtifactTypeID = 10

-- 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....?

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,

Each 'Tel' will relate to a one or more records in the PHONES table that is linked back to the customer.

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!
