I have two tables in SQL 6.5 database with identical fields and indexes. One
contains the data of August 2003 and other July 2003. Now the august table
is larger ( about 40000 more rows ) than the july table but i've noticed
that the same queries perform much faster on the august table than the july
table. Ive tried this with many different queries so i'm wondering whats the
reason behind this. Is there a way to optimize a table? Remember , I'm using
SQL 6.5
CREATE TABLE [Sales].[Test_inmem] ( [c1] [int] NOT NULL, [c2] [nvarchar](20) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL, [ModifiedDate] [datetime2](7) NOT NULL CONSTRAINT [IMDF_Test_ModifiedDate] DEFAULT (sysdatetime()),
[Code] ....
I have to generate 1000000 random records into it. I tried various ways to insert records, but not being a developer could not do it. I hope to make the C1 as a serial number, C2 can be anything, C3 I want to be the timestamp.
I've been having some trouble getting a single-column "varchar(5)" field to reliably use a table seek instead of a table scan. The production table in this case contains 25 million rows. As impressive as it is to scan 25 million rows in 35 seconds, the query should run much faster.
Typically, this table is accessed with a query that includes:
SELECT ... FROM SummaryTable WHERE ixZIP IN (SELECT ZipCode FROM @ZipCodesForMO)
This query insists on using a table scan. I've tried WITH (FORCESEEK) for example, but that just makes the query fail.
As I've investigated this issue I also tried:
SELECT * FROM Summaries WHERE ZipCode IN ('xxxxx', 'xxxxx', 'xxxxx')
When I run this query with 64 or fewer (actual, valid) ZIP codes, the query uses a table seek.But when I give it 65 or more ZIP codes it uses a table scan.
To summarize, the production query always uses a table scan, and when I specify 65 or more ZIP codes the query also uses a table scan. I'm wondering if the data type of the indexed column (Latin1_General_100_BIN2) is somehow the problem. I'll likely try converting the ZIP codes to an integer to see what happens.
I try to load data into a memOpt table (INSERT INTO ... SELECT ... FROM ...). The source table has a size about 1 Gb and 13 Mio Rows. During this load the LDF File grows to size of 350 GB (until the space if the disk is run out of space). The Server has about 110 GB Memory for the SQL Server reserved. The tempdB doesn't grow. The Bucket Size in the create statement has a size of 262144. The Hash key as 4 fields`(2 fields have the datatype int,1 has smallint, 1 has varchar(200). ) The disk for the datafiles has still space for the datafiles (incl. the hekaton files).
How can I reduce the size of the ldf files during the load of the data ?
Is it some how The following sp can be optimized? IF @groupID='812846' BEGIN IF (SELECT count(*) from Employee where SSN= @SSN and groupID=@groupID) > 0 BEGIN UPDATE Employee SET NameLast=@LastName, NameFirst=@FirstName, NameMiddle=@MI,

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:

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*/
I have this query that is taking more than 5 minutes to run, granted it involves 7 tables, 4 of which have over 100000+ rows, but there must be a quicker way of executing this.

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?
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?
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!
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?
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.
How do i find Total allocated space and used space of a memory optimized filegroup?
use memory_optimized_db Go select (SUM(size)*8.0)/1024.0 as Space, FILEGROUP_NAME ( data_space_id ) , type_desc from sys.database_files group by data_space_id,type_desc;
above query gives "current used size of the container " of memory optimized file group but doesn't give Total space detail.
- An MSSQL 2014 Standard server that houses multiple small databases (in excess of a hundred). - These databases are frequently dropped and restored by an application that uses this SQL Server. - There is a business need for this setup at this time, so I can't get away from it. Therefore answers like "don't have so many small databases that are frequently dropped and restored" would be somewhat unuseful
This is the problem I have:
- When I connect SSMS 2014 to the server and expand the "Databases" node, it takes forever to display. In comparison, SSMS 2008 connected to SQL 2008R2 server with the same number of databases displays the Databases tree very quickly.
I ran a trace to see what exactly SSMS 2014 is doing. When the "Databases" node is expanded, it runs a query that checks each database for Memory-Optimized Tables (new and wonderful feature of SQL 2014 for sure, but I'm not using it, at least yet). Naturally, when you have to loop through over a hundred DBs, it takes time. Worse yet, if one of these DBs is in process of being restored, the query sits and waits to time out before proceeding to the next DB. Sometimes this causes outright timeouts. Here is the query:
use [MyDatabase] SELECT ISNULL((select top 1 1 from sys.filegroups FG where FG.[type] = 'FX'), 0) AS [HasMemoryOptimizedObjects]
To be sure, this is NOT a SQL Server performance issue. This server processes a rather heavy workload and has been doing so for over a month, and the workload completes within expected time limits or better. Even so I've done some basic performance measuring, and the server itself is quite all right.
Moreover, if I connect SSMS 2008 to it, I get an error message (Index out of bounds or somesuch), but SSMS 2008 does connect, and displays the Databases tree much faster than SSMS 2014.
I'd like to turn off the option to check for Memory Optimized Objects altogether, as I'm not using the feature.
I've a database with a memory optimized filegroup on it. How can I remove it?I have removed the memory optimized table I had on it, but when I try to remove the filegroup I receive an error.
I am using SQL Server 2005 and trying to create a linked server on Oracle 10. I used the commands below: EXEC sp_addlinkedserver @server = 'test1', @srvproduct = 'Oracle', @provider = 'MSDAORA', @datasrc = 'testsource' exec sp_addlinkedsrvlogin @rmtsrvname = 'test1', @useself = 'false', @rmtuser='sp', @rmtpassword='sp'
When I execute select * from test1...COUNTRY I get the error. "The OLE DB provider "MSDAORA" for linked server "...." does not contain the table "COUNTRY". The table either does not exist or the current user does not have permissions on that table." The 'sp' user I am connecting is the owner of the table. What could be the problem ? Thanks a lot.
I have created a table Table with name as Varchar and id as int. Now i have started inserting the rows like, insert into Table values ('arun',20).Yes i have inserted a row in the table. Now i have got the values " arun's ", 50. insert into Table values('arun's',20) My sqlserver is giving me an error instead of inserting the row. How will you solve this problem?
I am having a table called as status ,in that table one field is there i.e. currentstatus. the rows which are having currentstatus as "ticket closed",i want to move those rows into other table called repository which is having same table structure as status table. I can do programatically. but is there any way for every 3 months system has to check and do this action means moving to repository table automatically?
I'm inserting from TempAccrual to VacationAccrual . It works nicely, however if I run this script again it will insert the same values again in VacationAccrual. How do I block that? IF there is a small change in one of the column in TempAccrual then allow insert. Here is my query
INSERT INTO vacationaccrual (empno, accrued_vacation, accrued_sick_effective_date, accrued_sick, import_date)
For reasons that are not relevant (though I explain them below *), Iwant, for all my users whatever privelige level, an SP which createsand inserts into a temporary table and then another SP which reads anddrops the same temporary table.My users are not able to create dbo tables (eg dbo.tblTest), but arepermitted to create tables under their own user (eg MyUser.tblTest). Ihave found that I can achieve my aim by using code like this . . .SET @SQL = 'CREATE TABLE ' + @MyUserName + '.' + 'tblTest(tstIDDATETIME)'EXEC (@SQL)SET @SQL = 'INSERT INTO ' + @MyUserName + '.' + 'tblTest(tstID) VALUES(GETDATE())'EXEC (@SQL)This becomes exceptionally cumbersome for the complex INSERT & SELECTcode. I'm looking for a simpler way.Simplified down, I am looking for something like this . . .CREATE PROCEDURE dbo.TestInsert ASCREATE TABLE tblTest(tstID DATETIME)INSERT INTO tblTest(tstID) VALUES(GETDATE())GOCREATE PROCEDURE dbo.TestSelect ASSELECT * FROM tblTestDROP TABLE tblTestIn the above example, if the SPs are owned by dbo (as above), CREATETABLE & DROP TABLE use MyUser.tblTest while INSERT & SELECT usedbo.tblTest.If the SPs are owned by the user (eg MyUser.TestInsert), it workscorrectly (MyUser.tblTest is used throughout) but I would have to havea pair of SPs for each user.* I have MS Access ADP front end linked to a SQL Server database. Forreports with complex datasets, it times out. Therefore it suit mypurposes to create a temporary table first and then to open the reportbased on that temporary table.
The following dbo.Tables of Northwind.mdf in my .SQLEXPRESS (SQL Server Management Studio Express) are missing: dbo.Categories dbo.CustomerCustomerDemo dbo.CustomerDemographics dbo.Customers dbo.Employees dbo.EmployeeTerritories dbo.Order Details dbo.Orders dbo.Products dbo.Regions dbo.Shippers dbo.Suppliers dbo.Territories.
But, I have these dbo.Tables in a different Database "xyzDatabase". How can I copy each of these dbo.Tables to the another blank dbo.Table of Northwind Database?
I right clicked on the dbo.Categories and I saw the following thing: dbo.Categories New Table... Modify Open Table Script Table as |> CREATYE To |> DROP To |> SELECT To |> INSERT To |> New Query Editor Window File.... Clipboard UPDATE To |> DELETE to |> From the above observation,I think it is possible to copy the dbo.Table from the one Database to the Northwind Database that needs to be repaired. Please help and advise me how to do this task or tell me where I can find the Microsoft document that gives the details of this X-copy thing.
Thanks in advance, Scott Chang
P. S. I am using VB 2005 Express to create a project to learn "Calling Stored Procedures with ADO.NET" (see Paul Kimmel's article in http://www.developer.com/db/article.php/3438221) that needs the dbo.Tables of Northwind Database and my Northwind Database has been screwed up for quite a while and needs a big repair.
