Stored Procedure Not Optimized
Feb 1, 2005
Hi ,
I created a page that list the total of hours, lunch time and expenses for the employees of the company.
I am trying to optimize this stored procedure , but it still takes more than 40 seconds for 50 employees.
select @StartDate As DateLigne, TPerson.Name, TPerson.idperson,
(select sum(coalesce(hours,0) - coalesce(lunch,0)) FROM Thereport
WHERE etridperson=TPerson.idperson AND etridproject=TUserProject.etridproject AND DateDIFF(day, @StartDate, datereport) >= 0 AND DateDIFF(day, datereport, @endDate) >= 0 ) As hours,
(select sum(coalesce(nonbillable,0)) FROM Thereport
WHERE etridperson=TPerson.idperson AND etridproject=TUserProject.etridproject AND DateDIFF(day, @StartDate, datereport) >= 0 AND DateDIFF(day, datereport, @endDate) >= 0 ) As nonbillable,
(select sum((coalesce(miles,0)*@mil)+ coalesce(perdiem,0)+coalesce(supplies,0)+coalesce(airfare,0)+ coalesce( gas,0) + coalesce(autorental,0)+ coalesce(other,0) ) FROM ThereportWHERE etridperson=TPerson.idperson AND etridproject=TUserProject.etridproject AND DateDIFF(day, @StartDate, datereport) >= 0 AND DateDIFF(day, datereport, @endDate) >= 0 ) As Expenses
FROM TUserProject, TPerson
WHERE TUserProject.etridperson=TPerson.idperson AND etridproject =89
Do you have any idea of how I could optimize this stored procedure?
Thanks

We are planning to upgrade. We are using Sql 2008R2 now. Which is the better option migrating to SQL 2012 or migrating to 2014?I am thinking 2014 has memory optimized tables and updatable column stored index. So it is better option.

Hi all - I'm trying to optimized my stored procedures to be a bit easier to maintain, and am sure this is possible, not am very unclear on the syntax to doing this correctly. For example, I have a simple stored procedure that takes a string as a parameter, and returns its resolved index that corresponds to a record in my database. ie
exec dbo.DeriveStatusID 'Created'
returns an int value as 1
(performed by "SELECT statusID FROM statusList WHERE statusName= 'Created')
but I also have a second stored procedure that needs to make reference to this procedure first, in order to resolve an id - ie:
exec dbo.AddProduct_Insert 'widget1'
which currently performs:SET @statusID = (SELECT statusID FROM statusList WHERE statusName='Created')INSERT INTO Products (productname, statusID) VALUES (''widget1', @statusID)
I want to simply the insert to perform (in one sproc):
SET @statusID = EXEC deriveStatusID ('Created')INSERT INTO Products (productname, statusID) VALUES (''widget1', @statusID)
This works fine if I call this stored procedure in code first, then pass it to the second stored procedure, but NOT if it is reference in the second stored procedure directly (I end up with an empty value for @statusID in this example).
My actual "Insert" stored procedures are far more complicated, but I am working towards lightening the business logic in my application ( it shouldn't have to pre-vet the data prior to executing a valid insert).
Hopefully this makes some sense - it doesn't seem right to me that this is impossible, and am fairly sure I'm just missing some simple syntax - can anyone assist?

Hi all,
I have 2 sets of sql code in my SQL Server Management Stidio Express (SSMSE):
(1) /////--spTopSixAnalytes.sql--///
USE ssmsExpressDB
GO
CREATE Procedure [dbo].[spTopSixAnalytes]
AS
SET ROWCOUNT 6
SELECT Labtests.Result AS TopSixAnalytes, LabTests.Unit, LabTests.AnalyteName
FROM LabTests
ORDER BY LabTests.Result DESC
GO
(2) /////--spTopSixAnalytesEXEC.sql--//////////////
USE ssmsExpressDB
GO
EXEC spTopSixAnalytes
GO
I executed them and got the following results in SSMSE:
TopSixAnalytes Unit AnalyteName
1 222.10 ug/Kg Acetone
2 220.30 ug/Kg Acetone
3 211.90 ug/Kg Acetone
4 140.30 ug/L Acetone
5 120.70 ug/L Acetone
6 90.70 ug/L Acetone
/////////////////////////////////////////////////////////////////////////////////////////////
Now, I try to use this Stored Procedure in my ADO.NET-VB 2005 Express programming:
//////////////////--spTopSixAnalytes.vb--///////////
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim sqlConnection As SqlConnection = New SqlConnection("Data Source = .SQLEXPRESS; Integrated Security = SSPI; Initial Catalog = ssmsExpressDB;")
Dim sqlDataAdapter As SqlDataAdapter = New SqlDataAdaptor("[spTopSixAnalytes]", sqlConnection)
sqlDataAdapter.SelectCommand.Command.Type = CommandType.StoredProcedure
'Pass the name of the DataSet through the overloaded contructor
'of the DataSet class.
Dim dataSet As DataSet ("ssmsExpressDB")
sqlConnection.Open()
sqlDataAdapter.Fill(DataSet)
sqlConnection.Close()
End Sub
End Class
///////////////////////////////////////////////////////////////////////////////////////////
I executed the above code and I got the following 4 errors:
Error #1: Type 'SqlConnection' is not defined (in Form1.vb)
Error #2: Type 'SqlDataAdapter' is not defined (in Form1.vb)
Error #3: Array bounds cannot appear in type specifiers (in Form1.vb)
Error #4: 'DataSet' is not a type and cannot be used as an expression (in Form1)
Please help and advise.
Thanks in advance,
Scott Chang
More Information for you to know:
I have the "ssmsExpressDB" database in the Database Expolorer of VB 2005 Express. But I do not know how to get the SqlConnection and the SqlDataAdapter into the Form1. I do not know how to get the Fill Method implemented properly.
I try to learn "Working with SELECT Statement in a Stored Procedure" for printing the 6 rows that are selected - they are not parameterized.

I have some code that I need to run every quarter. I have many that are similar to this one so I wanted to input two parameters rather than searching and replacing the values. I have another stored procedure that's executed from this one that I will also parameter-ize. The problem I'm having is in embedding a parameter in the name of the called procedure (exec statement at the end of the code). I tried it as I'm showing and it errored. I tried googling but I couldn't find anything related to this. Maybe I just don't have the right keywords. what is the syntax?
CREATE PROCEDURE [dbo].[runDMQ3_2014LDLComplete]
@QQ_YYYY char(7),
@YYYYQQ char(8)
AS
begin
SET NOCOUNT ON;
select [provider group],provider, NPI, [01-Total Patients with DM], [02-Total DM Patients with LDL],

let said, i have a table which contains a column with value such as:
,1,2,3,4,5,6,
,3,4,5,
,1,2,4,
and then i use the query:
select col1, col2 from table (nolock) where (col3 like ',1,' or col3 like ',3,')
is there any function which can be used to speed up the query or which more optimized one? Maybe something similar to IN(xxxx,xxxx,xxxx)

I started with this query:
SELECT procs.name as ProcName,

types.name as ParamType,
params.max_length,
params.precision,
params.scale,
params.is_output,
params.has_default_value

AND procs.name = 'webservices_BENEFICIAL_USES_DM_SELECT'
ORDER BY procname,
params.parameter_id
Now, all I need from it is the column params.is_output.
I have modified it down to what I need, but I'm wondering if I can remove some of the joins or anything else for better performance without losing the proper results:
SELECT params.is_output

LEFT OUTER JOIN sys.types types

Any idea how I could do this efficiently?
For example, the SiteName & SLAClass field using select statements each time may bog down the system.
Also, I’d like to feed the CustID and Subject fields from another table call Profile instead of typing the CustID field each time.
The result of this statement is to search for customers in the subject line and if customer is found then add the customer information into the Detail table. The Profile table contains all customer information.
UPDATE [TEST3].[dbo].[Detail]
SET [CustID] = 'Book Fairs' /*fill in with field from the Profile table automatically*/
,[SiteName] = (SELECT distinct([Profile].[SiteName] )
FROM [TEST3].[dbo].[Profile], [TEST3].[dbo].[Detail]
WHERE [Profile].[CustID] = [Detail].[CustID])
,[SLAClass] = (SELECT distinct([Profile].[SLAClass])
FROM [TEST3].[dbo].[Profile], [TEST3].[dbo].[Detail]
WHERE [Profile].[CustID] = [Detail].[CustID])
WHERE [Detail].[CallID] IN
(SELECT [CallLog].[CallID] FROM [TEST3].[dbo].[CallLog], [TEST3].[dbo].[Subset], [TEST3].[dbo].[Asgnmnt]
WHERE [CallLog].[CallType] = 'DREAM' AND
[CallLog].[Subject] LIKE '%Book Fairs%' ) /*fill in with field from the Profile table automatically*/

Can anyone give me any suggestions of how I could speed this up?
Also, I have noticed that sqlservr.exe is using more than 1.5GB of the 2GB in the machine while doing conversions from flat files to the database while the CPU is under 3% load, is this action typical of MSSQL2005?
Any help with this would be greatly appreciated.

I have a stored procedure that calls a msdb stored procedure internally. I granted the login execute rights on the outer sproc but it still vomits when it tries to execute the inner. Says I don't have the privileges, which makes sense.
How can I grant permissions to a login to execute msdb.dbo.sp_update_schedule()? Or is there a way I can impersonate the sysadmin user for the call by using Execute As sysadmin some how?

Has anyone encountered cases in which a proc executed by DTS has the following behavior:
1) underperforms the same proc when executed in DTS as opposed to SQL Server Managemet Studio
2) underperforms an ad-hoc version of the same query (UPDATE) executed in SQL Server Managemet Studio
What could explain this?
Obviously,
All three scenarios are executed against the same database and hit the exact same tables and indices.
Query plans show that one step, a Clustered Index Seek, consumes most of the resources (57%) and for that the estimated rows = 1 and actual rows is 10 of 1000's time higher. (~ 23000).
The DTS execution effectively never finishes even after many hours (10+)
The Stored procedure execution will finish in 6 minutes (executed after the update ad-hoc query)
The Update ad-hoc query will finish in 2 minutes

Hi,
I am used to writing Sub-Correlated queries within my main queries. Although they work fine but i have read alot that they have performance hits. Also, as with time our data has increased, a simple SELECT statement with a few Sub-Queries tends to run slower which may be between 10-15 seconds. Following will be a simple example of what i mostly do:
SELECT DISTINCT C.CusID, C.Name, C.Age,
(
SELECT SUM (Price)
FROM CusotmerOrder
WHERE CusID_fk = CO.CusID_fk
) Total_Order_Price,
(
SELECT SUM (Concession)
FROM CusotmerOrder
WHERE CusID_fk = CO.CusID_fk
) Total_Order_Concession,
(
SELECT SUM (Price) - SUM (Concession)
FROM CusotmerOrder
WHERE CusID_fk = CO.CusID_fk
) Total_Difference
FROM Customer C
INNER JOIN CustomerOrder CO
ON C.CusID = CO.CusID_fk
......
WHERE (conditions...)
My question is what would be a better way to handle the above query? How can i write a better yet simple query with optimized performance. I would also mention that in some of my asp.net applications, i use inline queries assigned to SqlCommand Object. The reason i mention it that since these queries are written in some class files, how would we still accomplish what i have mentioned above. Kindly could any Query Guru guide me writing better queries. I shall be obliged...

Hello :-)My question is: If I query a partitioned view, but don't know the valuesin the "where x in(<expression>)" clause, i.e.: select * from viewAwhere intVal in(select intVal from tbl1) . Compared to: select * fromviewA where intVal in(5,6).Of course "intVal" is partitioning column.Will this result in an optimized query that searches only the relevanttables?*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!

I have a question concerning where to put certain database files for the followinig RAID configurations. The server has 2 RAID configs: 2 hds in a RAID 1 and 4 hds in a RAID 10. The server will host 4 database instances: A replicated db, a Reporting Services db (which technically constitutes 2 db instances) and an application db.
In order to get the best performance, should I put the OS, SQL binary and log files on the RAID 1 config with the data and tempdb on the RAID 10? If not, please explain the best solution. Thank you!

Whenever I tried to right click stored procedure and select step into store procedure> i get following error
"User 'Unknown user' could not execute stored procedure 'master.dbo.sp_enable_sql_debug' on SQL server XXXXX. Click Help for more information"
I am not sure what needs to be done on sql server side
We tried to search for sp_enable_sql_debug but I could not find this stored procedure under master.
Some web page I came accross says that "I must have an administratorial rights to debug" but I am not sure what does that mean?
Please advise..

We have a situation where queries against a partitioned view ignore a suitable index and perform a table scan (against 200+MB of data), where the same query on the underlying table(s) results in a 4 page index seek. I can€™t find any mention of the situation, so I€™m trying a post here.
We€™re running SQL Server 2005 Enterprise edition sp2 on Windows 2003 Enterprise Edition sp1 on a two node cluster, and it also occurs on a stand-alone development box with Developer edition. We have four tables, named Options#0, Options#1, Options#2, and Options#3. All are almost identical (script generated by SSMS and edited down a bit):
SET ANSI_NULLS OFF
SET QUOTED_IDENTIFIER ON
CREATE TABLE [dbo].[Options#0](
[ControlID] [tinyint] NOT NULL CONSTRAINT [DF_Options#0__ControlID] DEFAULT ((0)),
[ModelCode] [char](8) NOT NULL,
[EquipmentID] [int] NOT NULL,
[AdjustmentContextID] [int] NOT NULL,
[EquipmentCode] [char](2) NOT NULL,
[EquipmentTypeCode] [char](1) NOT NULL,
[Description] [varchar](50) NOT NULL,
[DisplayOrder] [smallint] NOT NULL,
[IsStandard] [bit] NOT NULL,
[Priority] [tinyint] NOT NULL,
[Status] [bit] NOT NULL,
[Adjustment] [int] NOT NULL,
CONSTRAINT [PK_Options#0] PRIMARY KEY CLUSTERED
(
[ModelCode] ASC,
[EquipmentID] ASC,
[AdjustmentContextID] ASC,
[ControlID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
ALTER TABLE [dbo].[Options#0] WITH CHECK ADD CONSTRAINT [CK_Options#0__ControlID] CHECK (([ControlID]=(0)))
ALTER TABLE [dbo].[Options#0] CHECK CONSTRAINT [CK_Options#0__ControlID]
The only differences between the tables are in the names and in the value defaulted to and CHECKed, which matches the table name (to support the partitioned view, of course).
We receive and load data ever week and every two month, and use an unlikely algorithm to load and manage its availability by running an ATLER on the view (to maintain the access rights defined for the hosting environment). Scripted out via SSMS, the view looks like:
SET ANSI_NULLS ON
SET QUOTED_IDENTIFIER ON
CREATE VIEW [dbo].[Options] AS select * from Options#1 union all select * from Options#3
The problem is that when we issue a query like
SELECT count(*)
from Options
where ControlID = 1
and ModelCode = '2004NIC9'
The resulting query (as checked via the query plan and SET STATISTICS IO on) will get €œpartitioned€?, running against the proper table, but it will ignore the query, perform a table scan, and churn through 200+MB of data. A Similar query run against the underlying table
SELECT count(*)
from Options#1
where ControlID = 1
and ModelCode = '2004NIC9'
(with or without the ControlID = 1 clause) will perform a Clustered Index Seek and read maybe 4 pages.
Analyzing the execution plan shows that the table query work like you€™d think, but for the query against the view we get a Clustered Index Scan, with predicate:
[DBName].[dbo].[Options#1].[ControlID]=(1) AND CONVERT_IMPLICIT(char(8),[ DBName].[dbo].[Options#1].[ModelCode],0)=€™2004NIC9€™
I get the same results when explicitly listing all columns in the view. The code page on the view and tables is the same (as determined by checking properties via SSMS).
Why is the table data column being implicitly converted to the data type that it already is? Why does this occur when working with the partitioned view but not with the actual table? Can this behavior be controlled or modified without losing the (incredibly useful) data loading management benefits of the partitioned view? I€™m guessing (and hoping) it€™s some subtle quirk or mis-setting, please set me on the right path!

I'm just beginning to experiment with memory optimised tables.
I have two sets of near identical tables - one set normal, the other set memory optimised with DURABILITY=SCHEMA_ONLY - and am running test queries against these. When I say that the two sets are "near identical", I mean that they are the same except for the primary keys: for the normal tables these are defined as PRIMARY KEY CLUSTERED whereas for the memory-optimed ones they are defined as PRIMARY KEY NONCLUSTERED HASH WITH (BUCKET_COUNT=nnnn) as per the requirements for such tables.
I then run a pair of test queries, again identical but one referencing the normal tables and the other referencing the memory optimised ones.
(The query uses an inner join on three tables with row counts of approx 3m rows, 100000 rows and 5000 rows.)
The query against the normal tables runs noticeably faster than that against the memory optimised ones. To try to find out why, I examined the execution plans. the plan for the memory optimised query suggests that I have a missing index: but of course I can't create this againsty a memory optimised table. Is this a bug or am I missing something? Why the performance between the two should be so different?

I read this: [URL] ....
Which says you must drop the database to remove the filegroup.
I deleted all the objects and then backed up the DB and restored it and the filegroup is still there.
I was skeptical but some of the comments made me think this might work.
Do I really have to restore from a pre-memory optimized state?

I have a store procedure (e.g. sp_FetchOpenItems) in which I would like to call an existing stored procedure (e.g. sp_FetchAnalysts). The stored proc, sp_FetchAnalysts returns a resultset of all analysts in the system.
I would like to call sp_FetchAnalysts from within sp_FetchOpenItems and insert the resultset from sp_FetchAnalysts into a local temporary table. Is this possible?
Thanks,
Kevin

The above stored procedure is related to a search screen where in User is able to search from a variety of fields that include userID (corresponding column Batch.Created_By) and batchID (corresponding column Batch.BatchID). The column UserID is a varchar whereas batchID is a numeric.
REQUIREMENT:
The stored procedure should cater to a typical search where any of the fields can be entered. meanwhile it also should be able to do a partial search on BatchID and UserID.
Please help me regarding the same.
Thanks in advance.

I have a stored procedure that among other things needs to get a total of hours worked. These hours are totaled by another stored procedure already. I would like to call the totaling stored procedure once for each user which required a loop sort of thing
for each user name in a temporary table (already done)
total = result from execute totaling stored procedure
Can you help with this
Thanks

Hi there
i have a stored procedure like this:
CREATE PROCEDURE SP_Main
AS
SET NOCOUNT ON
BEGIN TRANSACTION
exec SP_Sub_One output
exec SP_Sub_Two output
IF @@ERROR = 0
BEGIN
-- Success. Commit the transaction.
Commit Tran
END
ELSE
Rollback Tran
return
GO
now the problem is, when i execute the stored procedure's inside the main stored procedure, and these sub sp's has an error on it, the main stored procedure doesnt rollback the transation.
now i can put the "begin transation" in the two sub stored procedure's. The problem is
what if the first "SP_Sub_One" executed successfully, and there was error in "SP_Sub_Two"
now the "SP_Sub_One" has been executed and i cant rollback it... the error occured in the
"SP_Sub_Two" stored procedure ... so it wont run ... so there will be error in the data
how can i make a mian "BEGIN TRANSACTION" , that even it include the execution of stored procedure in it.
Thanks in advance
Mahmoud Manasrah
