Dose It Make Sense To Create Indexted Views On A Single Table?
Apr 24, 2007
Hi, all experts here,
Thank you very much for your kind attention.
I am wondering if there is any sense to create indexed views on single table? I simple want to improve the report query performance as most of the reports data are from a single table. As views most of the time are created as for joined across tables.
Thank you very much for your advices and I am looking forward to hearing from you shortly.
I have inherited a SQL 2005 server with a few small databases on it. There's a maintenance plan here that doesn't seem to make a lot of sense to me. Can anyone comment:
Every Sunday at 4:00 AM
1. Reorganize index on All user database Tables and Views - compact large objects. 2. Rebuild index on local server connection, All user databases, Tables and view, Original amount of free space. 3. Shrink database. All user databases. Limit 100MB.
I'm confused a little about item 3. Won't a shrink be kind of useless after all of the work that goes on in steps 1 and 2. When I ran this manually, the transaction logs jumped significantly.
l've written a cursor to koop through a table and then insert the last 100 records into a table.Reason why l want the last 100 records is to monitor and log the last 100 trans avery hr or so.
-- Declare the variables to store the values returned by FETCH. SET ROWCOUNT 100 DECLARE @customer_No char(15), @loan_No char(12), @date_Issued datetime , @maturity_Date datetime , @status int
DECLARE loan_cursor CURSOR FOR SELECT customer_No, loan_No, date_Issued, maturity_Date, status
FROM loan
OPEN loan_cursor
-- Perform the first fetch and store the values in variables.
FETCH NEXT FROM loan_cursor INTO @customer_No, @loan_No, @date_Issued , @maturity_Date, @status,
-- Check @@FETCH_STATUS to see if there are any more rows to fetch.
WHILE @@FETCH_STATUS = 0 BEGIN
-- This is executed as long as the previous fetch succeeds. FETCH NEXT FROM loan_cursor INTO @customer_No , @loan_No , @date_Issued , @maturity_Date , @status END
CLOSE loan_cursor
DEALLOCATE loan_cursor;
insert into Loan1 (customer_No, loan_No, date_Issued , maturity_Date , status )
select @customer_No, @loan_No, @date_Issued, @maturity_Date, @status FROM loan ORDER BY date_Issued desc;
I need any one's advice/imput on this...PLEASE!My computer will now begin the process of taking all the MS Access (NativeJet Engines - x30 total departmetns) and put the tbles/BE on SQL Server 2005and the Ms Access FE on MS Sharepoint.This is the kicker, say 20 out of the 30 (ball park) was created by oneperson and that is their whole job function was to create/maintain a QAtracking system and more.The person who created the 20 out 30 only knows intermediate ms access andsome vba, but NOT sql or net conversions (visual studio - all the differentlanguages), so the IT director asks me (I develop in MS Access andintermediate in VBA and can create web sites using publisher, front page andHTML) he asks me and this other person if we want to take on the challenge ofhelping him and the other IT guy in the conversion process of all of thesedb's.What does this do the developers who developed and still maintain thesecurrent 30 ms access db's, well you guessed it, it now takes all that hardwork that those developers did and still do (they still add more forms,updates) and it NOW takes the databases owners away from them and grant itnow to the person (s) who will maintain SQL Server 2005 ( I hope will be aDBA)???Is this true, once all the databases are converted, the owners will no longerbe able to go behind the scenes in tables, queries,etc.... It will now be inthe hands of a DBA?You know the funny thing is the IT Director wasn't even sure if he was goingto hire a DBA, who in the heck will maintain all of those db's on the server?There is only one other guy and he certainly does not have the training orskills or TIME.MY POINT QUESTION IS:when these conversion take place like this at a company, most of the time thems access dbs that have now be put into sql will now take the ownership awayfrom the owner (they cannot develop no more, unless they are sql friendly/dba)and put all of that into one persons hand (DBA) to maintain and development??????--Message posted via SQLMonster.comhttp://www.sqlmonster.com/Uwe/Forum...eneral/200606/1
Thanks to several guys here, I now understand how SQL Server configuration option works... Pretty nifty stuff.
Now, I'm trying to see if I can configure the Server property of the Connection Manager that holds the information for where my configuration table is. I thought about this and tried it, but it doesn't work. Then it occurred to me, this may not make sense to try to do because it is like the question, "what came first? the egg or the chicken?"
I am new to SSIS. i am trying to port database from SQL SERVER 2000 to 2005. i am using "Transfer SQL Server Objects" for this. i am just trying to move one object for testing wether it works or not. and it is not working. i am getting this error.
[Transfer SQL Server Objects Task] Error: Execution failed with the following error: "ERROR : errorCode=-1071636471 description=An OLE DB error has occurred. Error code: 0x80040E37.

Both DBs are on seprate machines. of you need any more info please let me know. that would be great help.
We started to develop a datawarehouse solution for client back in December 2008 based on SQL 2008. We are convinced that we can use some of the new feature included in the new version which is the reason we we chossed to go down this path.
Due to the delay of the next version we have some question that I would like to hear you opinion on.
The estimatet "go live" date is during spring (march/april)
Is it wrong to contiue the development on the 2008 version?
We would need to run Release candidate at the customer site until the product is released. Is there any major changes coming up that are already known?
So far in the development we have had no big problems with releasecandidate.
We are importing a very small subset of a big desktop database into a CE database on a mobile device for an occasionally connected application. The idea is that the mobile device can use this CE database as a fall back database in case we are not connected.
The database is a very simple list of barcodes.
Basically a single field as primary key
EAN13 bigint
When we import 200K rows (yes we have quite a lot of them). The database is 7MB!!!! A bit big I would say since 8 bytes times 200.000 is only 1.5 MB. Where does the extra space come from?
I'm troubleshooting a stored procedure that suddenly decided to stop working. I narrowed down the problem to the last part of the stored procedure where it selects data from a temp table and inserts it into a physical table in the SQL2000 database.
I keep receiving the following error:
Server: Msg 8115, Level 16, State 8, Line 140 Arithmetic overflow error converting numeric to data type numeric.
The data values all appear to be correct with none of them seeming to be out of precision, but I keep getting the error. I've tried casting all the values and it didn't work. It executes w/o error when I comment out that particular insert. I just don't get it.

I've looked at the other threads on this topic, and don't see an answer to the following question:
Why should an error destination time out waiting for error rows?
I'm using SQL Server Destinations both for my staging tables and for my "Error Staging" tables. Yet it seems that these are timing out if the package runs a long time without any error rows. This leads to two questiosn:
Why should an error destination time out waiting for error rows?
I can solve this by setting the timeouts to some very large number. But, is there a better way to do this? Right now, if the package takes five minutes, I need to set the timeouts to longer than five minutes. That does not sound like a good idea.
In short, we have started deploying Office 2007 to our users and Excel is currently the only client we use to interact with our AS2005 cubes.
A few users have reported issues (which I've verified), but the explanation in the KB article doesn't make any sense to me. These reports were originally developed in Excel 2003 and when opening them up in Excel 2007, we'll see a message saying that Excel found unreadable content in the .xls file and after clicking 'Yes' to recover contents of the workbook, we then receive a message that a PivotTable report was discarded due to integrity problems. If I opened up this report in Excel 2003, I don't receive these errors or messages.
Per the KB's explanation (http://support.microsoft.com/default.aspx/kb/929766):
This issue occurs if the following conditions are true: €¢The workbook contains a PivotTable that uses key performance indicators (KPIs).€¢The KPIs are created in the Analysis Services Business Intelligence Development Studio.€¢One or more of the KPIs have an expression in the Current Time Member property. Now, we are running 2005 Standard Edition with no SP, but will be deploying SP2 in a few days. Our cubes do not have any KPIs defined. Can I even define KPIs if we are only running Standard Edition?
I would like to create a procedure which create views by taking parameters the table name and a field value (@Dist).
However I still receive the must declare the scalar variable "@Dist" error message although I use .sp_executesql for executing the particularized query.
Below code.
ALTER Procedure [dbo].[sp_ViewCreate] /* Input Parameters */ @TableName Varchar(20), @Dist Varchar(20) AS Declare @SQLQuery AS NVarchar(4000) Declare @ParamDefinition AS NVarchar(2000)
I'm a real novice user and I we use SQL Server. I have a table called TableLog that has the 4 columns. The first column is repeated x number of times for each value in the second column. I'd like to see this information put into a matrix where I could tell if there are any missing intersections. In addition, I need to insert a WHERE clause that says "BETWEEN 20090000 AND 20100000" for the first and second columns.
i have 6 table in SQL Server and i have created one view and create single table by linking all the table,now i want to join two column like
Column A and Column B = Column C e.g A B C Atul Jadhav Atuljadhav Vijay vijayvijay
in above exambe column A having firstName and Column B having second name and i want to join this two column in C column "atuljadhav" and if column B is blank then it join A value tow timestriger code as it is auto update column and every time (update, append, modify, delete) it should be update automatic
I am trying a create views that would join 2 tables:
Table 1: Has all the columns need by a view ( Name: Product Structure: ID, Attribute 1, Attribute 2, Attribute 3, Attribute 4, Attribute 5 etc Table 2: Is a lookup table that provides the names of columns Name: lookupTable Structure: tableName, ColumnName, columnValue Values: Product, Attribute1, Color Product, Attribute2, Size Product, Attribute3, Flavor Product, Attribute4, Shape
We are trying to do some utilization calculations that need to factor in a given number of holiday hours per month.
I have a date dimension table (dimdate). Has a row for every day of every year (2006-2015)
I have a work entry fact table (timedetail). Has a row for every work entry. Each row has a worked date, and this column has a relationship to dimdate.
Our holidays fluctuate, and we offer floating holidays that our staff get to pick. So we cannot hard code which individual dates in dimdate as holidays. So what we have done is added a column to our dimdate table called HolidayHoursPerMonth.Â
This column will list the number of holiday hours available in the given month that the individual date happens to fall within, thus there are a lot of duplicates. Below is a brief example of dimdate. In the example below, there are 0 holiday hours for the month of June, and their are 8 holiday hours for the month of July.
I have a pivot table create based of the fact table. I then have various date slicers from the dimension table (i.e. year, month). If I simply drag this column into the pivot table and summarize by MAX it works when you are sliced on a single month, but breaks if anything but a single month is sliced on. Â
I am trying to create a measure that calculates the amount of holiday hours based on the what's sliced, but only using a single value for each month. For example July should just be 8, not 8 x #of days in the month.Â
Listed below is how many hours per month. So if you were to slice on an entire year, the measure should equal 64. If you sliced on Jan, Feb and March, the measure should equal 12. If you were to slice nothing, thus including all 15 years in our dimdate table, the measure should equal 640 (10 years x 64 hours per year).
I have two separete databases, what Ineed is that I want to make a single database of the two. Although all the table definitions of both the database are same.
I will be glad to know "how to make a single database from two" and i will be happy to see the query to insert the values from one database to another one.
I've a doubt regarding deploying and creating package (MSI and EXE files) for SQL Stored procedures,views,tables,functions,triggers etc.,just like ASP.NET application by publishing and deploying..Is it possible in the same way for sql objects.If so,pls help me how to do it?
I have 2 views which contain the following fields: EVENT, WEEK, SUBSCRIPTION, QTY, GROSS_AMOUNT, SEASON
The 2 views differ by SEASON. I'm attempting to combine the 2 views in to a single view or table grouping by EVENT, WEEK and SUBSCRIPTION:
EVENT, WEEK, SUBSCRIPTION, Q6 (qty of season 1), A6 (gross_amount of season 1), Q7 (qty of season 2), A7 (gross_amount of season 2)
Below is my select command:
------
SELECT TOP 100 PERCENT dbo.vw_SEASON06.EVENT, SUM(dbo.vw_SEASON06.QTY) AS Q6, SUM(dbo.vw_SEASON06.GROSS_AMOUNT) AS A6, SUM(dbo.vw_SEASON07.QTY) AS Q7, SUM(dbo.vw_SEASON07.GROSS_AMOUNT) AS A7, dbo.vw_SEASON06.WEEK, dbo.vw_SEASON06.SUBSCRIPTION
FROM dbo.vw_SEASON06 FULL OUTER JOIN dbo.vw_SEASON07 ON dbo.vw_SEASON06.WEEK = dbo.vw_SEASON07.WEEK AND dbo.vw_SEASON06.SUBSCRIPTION= dbo.vw_SEASON07.SUBSCRIPTION AND dbo.vw_SEASON06.EVENT = dbo.vw_SEASON07.EVENT
GROUP BY dbo.vw_SEASON06.EVENT, dbo.vw_SEASON06.WEEK, dbo.vw_SEASON06.SUBSCRIPTION
ORDER BY dbo.vw_SEASON06.EVENT
-----
This creates the view but there are some issues. If an 'EVENT' exists in dbo.vw_SEASON07.EVENT and doesn't exist in dbo.vw_SEASON06.EVENT the value of the field 'EVENT' is set to NULL because the 'EVENT' name is returned from dbo.vw_SEASON06.EVENT. The same issue exists for 'SUBSCRIPTIONS' and 'WEEK'.
How can I create a single view/table that will include all the data from these 2 views without the NULL values in EVENT or SUBSCRIPTION?
I am developing an application for a big office which uses SQL Server 2000. Apart from my database, on that server, there are two databases by other companies. The administrator also has access to server but the client only wants him to backup the database.
I have two questions:
1) First of all (if it is possible) I would like to protect my own database from the other companies.
I don't want them to:
see the data in the tables (around 20 tables) make changes to the stored procedures (more than 100 stored procedures) be able to backup the database
2) The client will save sensitive data to the database (mainly currency amounts, salaries etc) which he wants to keep hidden. I am using float type for these fields and I would like to make the data encrypted. I could do it for nvarchar fields but changing these float to nvarchar would be time consuming.
When I create a view using Enterprise Manager, I can click on the 'Add Table' button to select a table. Is there any way I can tell EM that I want to include a table from another server?
I am using SqlServer2005 and asp.net 2005. I have a large database for which I have to provide reports for it. I need a report that user will specify a date, and the report will be run, from this month & year and I will calculate the first day of the month and the last day of the month and these will serve as the input parameters for a long SELECT query.For my previous reports i've used views . But for this functionality i need a parameterized view, which i cant create.Please help me how to create a parameterized view.... Thanks in Advance...
I am very new to database and have a question about views, that I hope someone can help me with, i am sure its simple:
I have to tables for storing different users, I want(for a log in function),to make a view that combine these to tables.
so all names stored in table1 under column customer_name, and all names stored in table2 under column name contact_name will in the view be stored under column username.
I am stuck on creating views using the variables. I keep on getting the 'CREATE VIEW' must be the first statement in a query batch error. I understand that views need to be the first statement, but I have a lot of views that need to reference specific variables - is there any way to do this?
The code I am using is as follows:
DECLARE @view varchar(MAX) DECLARE @database varchar(30) SET @database = 'KateTEST3'
--Insert views SET @view = 'USE ['+@database+'] SET ANSI_NULLS ON SET QUOTED_IDENTIFIER ON;
CREATE view [dbo].[userssupplier] as SELECT * FROM dbo.Users WHERE (User_Type = 4.0) OR (User_Type = 5.2)' EXEC(@view)
I have my program create and load (restore) a database, then create a login and make it dbowner by running a script like below via OSQL:
EXEC sp_addlinkedserver 'SETUP1myserver','SQL Server' EXEC sp_serveroption 'SETUP1myserver','DATA ACCESS', 'TRUE' GO DROP DATABASE [mydb] GO EXEC sp_droplogin 'mylogin' GO CREATE DATABASE [mydb] ON (NAME = N'mydb_data', FILENAME = N'C:AppfolderSQLmydb.mdf' , SIZE = 100, FILEGROWTH = 10%) LOG ON (NAME = N'mydb_log', FILENAME = N'C:AppfolderSQLmydb.ldf' , FILEGROWTH = 10%) COLLATE Latin1_General_CI_AS GO RESTORE DATABASE mydb FROM DISK = 'C:AppfolderSetupmydb.bak' WITH REPLACE, MOVE 'mydb_data' TO 'C:AppfolderSQLmydb.mdf', MOVE 'mydb_log' TO 'C:AppfolderSQLmydb.ldf' GO EXEC sp_addlogin 'mylogin','pass1$' GO USE mydb EXEC sp_changedbowner 'mylogin' GO
This works fine to a point. The program can then connect to the database and carry out normal processing with the "mylogin" user/password but it cannot do administration activities that a dbowner can do.
How do I create a login that does have true dbowner rights?
In SQL 2K...i need to write a script that writes a script that creates all views in the order that they are nested and I am feeling lazy. Does anyone have anything handy?For example if View_BOB says...CREATE VIEW VIEW_BOBASSELECT COL_1 FROM VIEW_JOHNI need the script to generate a script that creates View_JOHN before View_BOB.
Hi,I am not getting option as 'new view' and 'new table' when I rightclick onviews and tables option in VisualStudio.net IDE server explorersqlservers database to create new objects.Looks like some setup issue in my database.Thanks for your help in advance.RgdsCV
I have a pretty large database that has tables that will contain millions of rows of records. I will predominantly be using Views just to select the data. (I will not be performing any updates or inserts). I propose creating indexes on the views. My question is - if I create indexes on my views, do I have to create them on the tables as well? Is it good practice to create indexes on tables by default even if I am not going to be performing select statements directly on my tables but via my indexed views? Any advice is appreciated.
