I have a table with several indexes, currently most of them are very narrow (one column), and the question is, when I modify the table by updating a record, does all the indexes are calculated again?? Even if the modified field isn't indexed??? Or the server is smart and knows what indexes to calculate if any.
Second question, can I give to a query a low priority(In dynamic SQL), for example when I don't want my query to exploit too many system resources so it won't interfere the main system ?
I am using SQL Server 2008 R2 SP1, and BIDS 2008 SP1. The problem I am about to define does NOT happen when the report is deployed to the report server, but only within the report development environment (BIDS).
From within BIDS my reports are fed by stored procedures. The problem is when I modify a stored procedure in Management Studio, and refresh the report from within BIDS, the report does not reflect the new changes made in the stored procedure. So far I have found one clumsy solution to this problem:
1) Go to the folder where the project is saved on the file system.
2)Find the ".data" file that is associated to the particular report, then delete it. For instance, if my report name is TestReport.rdl, find the file named TestReport.rdl.data, then delete it.
I created am inventory table with few columns say, Servername, version, patching details, etc
I want a tracking of the table.
Let's say people are asked to modify the base table and I want a complete capture of the details modified and the session of the user ( ) who (system_user) is actually modifying the details.
Does anyone know how to get a table's 'last modified date' in SQL 7 ? Sysobjects contains the 'create date', but I can't find a 'last modified date' anywhere......
I am looking for two sql scripts,1. How can i check when a tables structure was last modified? 2. How can i find the structure differences between two databases that were created the same but changed over time individualy?Looking for sql scripts to do this. Any help on either would be great.Thanks
Is anyone aware of a method of determining when a table was last modified or accessed?
Some of our databases have tables that I am sure are not being used and I would like to generate a list of tables that have not been accessed or modified for some period of time.
I looked for a system procedure but didn't see anything that satisfied my need.
Currently I rename suspect tables and wait for someone or some process to gripe, but I don't care for that method for obvious reasons.

I want to pick the recent modified date for DepCode and sum Yearly and Monthly Amount. I have tried this query and not able to get the output. This is the single table.
select B1.[ID], B1.[AppName], B1.[DepCode], B1.[DepName], B1.[Group], B2.ModifiedDate, B2.YearlyAmount, B2.MonthlyAmount, B1.[FuBded], B1.[AppCategory], B1.[Research] FROM Business B1 INNER JOIN (select [ID], MAX(ModifiedDate) as ModifiedDate, SUM(YearlyAmount) as YearlyAmount, SUM(MonthlyAmount) as MonthlyAmount from Business Group by ID) B2 ON B1.ID = B2.ID AND B1.ModifiedDate = B2.ModifiedDate
If I have a view such as: SELECT T.* FROM T When I add a column to table T the view is not updated to reflect that change. Furthermore, if there are other columns after the * in the view (for example SELECT T.*, GETDATE() as "My Date" FROM T) the last columns will contain incorrect data.
Is there a work around for this? An "auto-recompile when tables are modified" kind of option?
Thanks Nick
PS: This is the script I used for testing:
create table tt ( test1 int primary key, test2 int) go insert into tt (test1, test2) values (1,2) go create view vw_tt as select *, getdate() as "My Date" from tt go select * from vw_tt go create view vw_tt2 as select * from tt go alter table tt add test3 int go select * from vw_tt select * from vw_tt2 select * from tt drop table tt drop view vw_tt drop view vw_tt2
Hello, I am using SQL Server 2005 and ASP.NET 2.0. We have a very simple content management system where we have to keep track of date last modified for each row in all of our content tables. I know there's a "timestamp" datatype that is used for replication scenarios, but is there anything similar that I can use to set up a date_modified column for each of my content tables that will automatically update with GETDATE() whenever anything in a given row is updated? Or do I have to create a date_modified column of smalldatetime datatype and write a trigger on update for EVERY single table of content that I have in the database? It seems there should be an easier way to do this than to write 20 triggers for my 20 content tables. Thanks!
I've a table with more columns and 1 identifier. I need to write this table when a modified row is detecting respect to the columns not to the identifier.
So I've created a temporary table to put the potential rows to write on the real table, but I want to detect the modified rows. I've thought to use the checksum function, but I don't know how to use it and if it could be useful in this scenario.
Moreover, in the temporary table I've collected daily the rows to write: the first day a row could have a value respect to his columns, the next day a different value and the next one the same value respect to the first day.
I need a little help here..I want to transfer ONLY new records AND update any modified recordsfrom Oracle into SQL Server using DTS. How should I go about it?a) how do I use global variable to get max date.Where and what DTS task should I use to complete the job? Data DrivenQuery? Transform data task? How ? can u give me samples. Perhaps youcan email me the Demo Package as well.b) so far, what I did was,- I have datemodified field in my Oracle table so that I can comparewith datelastrun of my DTS package to get new records- records in Oracle having datemodified >Max(datelastrun), and transferto SQL Server table.Now, I am stuck as to where should I proceed - how can I transfer theserecords?Hope u can give me some lights. Thank you in advance.
Any one please tell me is there any possible way to identify the table modified date.
I have checked the table created date from sysobjects or by right click properties. my requirement is to identify the exact date of table modification and column creation,alter dates. Is there any such provision in sql server 2000 or 2005 , My application is in sql server 2000.
I need to confirm this because some database structure modification has affected my application and causing dataloss i need to check with the date of structural change of table and lost data date can any one help
I am using the Maintencance Plan wizard, but it only allows me to either select the "reorganize data and indexes" option or the "update statistics" option (in the Optimizations tab). I can't select both of them. What is the reason for this?
We are planning to standardize our newly deployed sql server, As a part of it we have configured 2 maintenance plans 1) Update Statistics which runs daily and 2) Index Reorganize which runs on weekly.
Apart from above, any other things to be in place for better maintenance of the sql server.
Also, how to Index Rebuild activity for clustered indexes requires any downtime.
I have a requirement to only rebuild the Clustered Indexes in the table ignoring the non clustered indexes as those are taken care of by the Clustered indexes.
In order to do that, I have taken the records based on the fragmentation %.
But unable to come up with a logic to only consider rebuilding the clustered indexes in the table.
Can someone tell me if it is possible to add an index to a Table variable that is declare as part of a table valued function ? I've tried the following but I can't get it to work.
ALTER FUNCTION dbo.fnSearch_GetJobsByOccurrence ( @param1 int, @param2 int ) RETURNS @Result TABLE (resultcol1 int, resultcol2 int) AS BEGIN

I'm looking for information on how to add indexes to a table in a SQL Server 2000 Database, why add them etc? Any source of good information on the web regarding this?
I'm working to improve performance on a database I've inherited, and there are several thousand indexes. I've got a list of ones which should definitely exist within the database, and I'm looking to strip out all the others and start fresh, though this list is still quite large (1000 or so).
Is there a way I can remove all the indexes that are not in my list without too much trouble? I.e. without having to manually go through them all individually. The list is currently in a csv file.
I'm looking to either automate the removal of indexes not in the list, or possibly to generate the Create statements for the indexes on the list and simply remove all indexes and then run these statements.
As an aside, when trying to list all indexes in the database, I've found various scripts to do this, but found they all seem to produce differing results. What is the best script to list all indexes?
