I am writing an in house utility to attempt to compare different
aspects of databases.
I am currently writing the queries to list all of the indexes in the
database (including primary key indexes at present - I may move these
and compare separately at some point).
I would like the following information, in one result set if possible:
Table Name
Index Name
Column Name
Column Position
Unique?
Now on Oracle, this is easily done with the following query:
SELECT IND.TABLE_NAME, IND.INDEX_NAME, IND.COLUMN_NAME,
IND.COLUMN_POSITION, COL.UNIQUENESS
FROM USER_IND_COLUMNS IND,
USER_INDEXES COL
WHEREIND.INDEX_NAME = COL.INDEX_NAME
ORDER BY 1, 2, 3, 4, 5
I have been trying for over an hour now to get the equivalent, and I
really cannot figure it out. If anybody can come up with this then I
would greatly appreciate it!
First, soapbox questions for someone who might have more direct pull with Microsoft (or at least knowledge of how I should work with what they've given us), then a more specific question: Scenario: You install SQL Server Express (or any other version, it doesn't matter) and the feedback with all the little green checkmarks tells you it has installed successfully. "Oh goody," say people (like me) who are not super experienced with SQL Server, "it installed successfully; now I can jump in and start using it!" But it aint so--there are so many other hoops to jump through before it really becomes operational. After successful installation, why can't some link become visible indicating what you have to do after that? I mean, it's fine to wade through all the questions in this forum and get answers from all you nice and informed guys, AFTER the problems start coming; but I would rather not have to associate with you, to be honest, in terms of time spent that could be going into my projects. Why isn't there a comprehensive guide right off the bat? That is, something referenced immediately that tells you such things as: how to register a database with emphasis on the fact that just creating a database won't do the trick for your application; how to set permissions and rights; that (what was I reading in the advice of one post?) you have to register both the database and the user, blah blah; all about instances, the web.config file, etc. etc. I mean, doesn't it seem logical that by virtue of a person installing the database, come on, that this is a pretty good indication that he/she in all likelihood is new at it? As it is now, all they tell you on the SSE site is that you have to have the .NET Framework installed; and the green checkmarks indicating that you've installed it correctly (sorry for mentioning that twice). "OK, self," I say, "I have the Framework installed and SSE installed correctly, so let's get to work." Then the trouble begins. Unless Microsoft's purpose is to keep you tech guys and book writers in business, I don't understand why they don't give more up-front guidance. Any thoughts on why they work it this way? Bueller, Bueller? Anyone, anyone? Now, to the question that's pressing me at the moment: I've installed SSE and I'm going through a tutorial ("How Do I: Create Data-Driven Web Sites?" on http://www.asp.net/getstarted/default.aspx?tabid=61). Yeah, the guy makes it look really easy. He creates a database then shuts down the connection. I try to do the same things and I'm informed that I don't even have a valid connection! How SQL-Server-Express fun and easy is that? It's a real AdventureWorks, if you ask me. OK, that's my rant; and since MS didn't think in advance and implement my idea of a link to jump off from the installation menu, I have to face the reality of learning this by putting all the pieces together myself. So, my question is, before I try to go through the video and get more frustrated, WHERE DO I GO FOR THE MOST BASIC OF ALL THE STEPS I NEED TO DO, ONE BY ONE? This is like the second "beginner" video I've tried to go through but even these don't start at the very beginning with information on how to register a new database, making the user a part of aspnetWHATEVER, what permissions to dole out, etc. Guidance is solicited and will be most appreciated. Thanks, Bryan
Hi, Does anyone here know of any on-line references on how to optimize index maintenance in sql 2005? Also do you know of any good DBA books that will explain database maintenance and or best practices?
please explain the differences btween this logical & phisicall operations that we can see therir graphical icons in execution plan tab in Management Studio
I have some troubles with IBM WebSphere Application Server using MS SQL Server 2005 JDBC Driver. I always get the error e.g. java.lang.SecurityException: class "com.microsoft.sqlserver.jdbc.SQLServerDatabaseMetaData"'s signer information does not match signer information of other classes in the same package
I found this Feedback but it seems to be closed.
A temporary solution for me was to delete the meta-inf directory of the JAR-File, but that can't be the solution.
I am using Full Text Index to index emails stored in BLOB column in a table. Index process parses stored emails, and, if there is one or more files attached to the email these documents get indexed too. In result when I'm querying the full text index for a word or phrase I am getting reference to the email containing the word of phrase if interest if the word was used in the email body OR if it was used in any document attached to the email.
How to distinguish in a Full Text query that the result came from an embedded document rather than from "main" document? Or if that's not possible how to disable indexing of embedded documents?
My goal is either to give a user an option if he or she wants to search emails (email bodies only) OR emails AND documents attached to them, or at least clearly indicate in the returned result the real source where the word or phrase has been found.
Web Base application or PDA devices use to initiate the order from all over the country. The issue is this table is not Partioned but good HP with 30 GB RAM is installed. this is main table that receive 18,0000 hits or more. All brokers and users are using this table to see the status of their order.
The always search by OrderID, or ClientID or order_SubNo, or enter any two like (Client_ID+Order_Sub_ID) or any combination.
Query takes to much time when ever server receive more querys. some orther indexes are also created on the same table like (OrderDate, OrdCreate Date and Status)
My Question are:-
Q1. IF Person "A" query to DB on Client_ID, then what Index will use ? (If any one do Query on any two combination like Client_ID+Order_ID, So what index will be uesd.? How does MS-SQL SERVER deal with these kind of issues.?
Q2. If i create 3 more indexes on ClientID, ORderID and OrdersubID. will this improve the performance of query.if person "A" search record on orderNo so what index will be used. (Mind it their would be 3 seprate indexes for Each PK columns) and composite-Clustered index is also available.?
Q3. I want to check what indexes has been used? on what search?
Q4. How can i check what table was populated when, or last date of update (DML)?
My Limitation is i Dont Create a Partioned table. I dont have permission to do it.

My SSIS package is running very slow taking so much time to execute, One task is taking 2hr for inserting 100k records, i have disabled unused index still it is taking time.I am rebuilding/Refreshing indexes and stats once in month if i try to execute on daily basis will it improve my SSIS Package performance?
hello friends i have table1 and 200 coulumn of table1 :) i have 647.600 records. i entered my records to table1 with for step to code lines in one day :) i select category1 category2 and category3 with select code but i have just one index.. it is productnumber and it is primarykey..So my select code lines is so slow.. it is 7-9 second.. how can i select in 0.1 second ? Should i create index for category1 and category2 and category3 ? But i dont know create index.. My select code lines is below.. Could you learn me and show me index for it ?? or Could you learn me and show me fast Select code lines and index or etc ??? Also my search code line have a dangerous releated to attaching table1 with hackers :) cheersi send 3 value of treview1 node and childnode and child.childnode to below page.aspx :) Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load If Not Me.IsPostBack Then If Request("TextBox1") IsNot Nothing ThenTextBox1.Text = Request("TextBox1") End If If Request("TextBox2") IsNot Nothing ThenTextBox2.Text = Request("TextBox2") End If If Request("TextBox3") IsNot Nothing ThenTextBox3.Text = Request("TextBox3") End If End If Dim searchword As String If Request("TextBox3") = "" And Request("TextBox2") = "" Then searchword = "Select * from urunlistesi where kategori= '" & Request("TextBox1") & "'" End If If Request("TextBox3") = "" Then searchword = "Select * from urunlistesi where kategori= '" & Request("TextBox1") & "' and kategori1= '" & Request("TextBox2") & "'" End If If Request("TextBox3") <> "" And Request("TextBox2") <> "" And Request("TextBox1") <> "" Then searchword = "Select * from urunlistesi where kategori= '" & Request("TextBox1") & "' and kategori1= '" & Request("TextBox2") & "' and kategori2= '" & Request("TextBox3") & "'" End If SqlDataSource1.SelectCommand = searchword End Sub
I'm running a merge replication on a sql2k machine to 6 sql2k subscribers. Since a few day's only one of the merge agents fail's with the following error:
The merge process could not retrieve generation information at the 'Subscriber'. The index entry for row ID was not found in index ID 3, of table 357576312, in database 'PBB006'.
All DBCC CHECKDB command's return 0 errors :confused: I'm not sure if the table that's referred to in the message is on the distribution side or the subscribers side? A select * from sysobjects where id=357576312 gives different results on both sides . .
Hi everyone, When we create a clustered index firstly, and then is it advantageous to create another index which is nonclustered ?? In my opinion, yes it is. Because, since we use clustered index first, our rows are sorted and so while using nonclustered index on this data file, finding adress of the record on this sorted data is really easier than finding adress of the record on unsorted data, is not it ??
I have a clustered index that consists of 3 int columns in this order: DateKey, LocationKey, ItemKey (there are many other columns in this data warehouse table such as quantities, prices, etc.).
Now I want to add a non-clustered index on just one of the other columns, say LocationKey, like this: CREATE INDEX IX_test on TableName (LocationKey)
I understand that the clustered index keys will also be added as key columns to any NC indexes. So, in this case the NC index will also get the other two columns from the clustered index added as key columns. But, in what order will they be added?
Will the resulting index keys on this new NC index effectively be:
LocationKey, DateKey, ItemKey OR LocationKey, ItemKey, DateKey
Do the clustering keys get added to a NC index in the same order as they are defined in the clustered index?
Quick question about the primary purpose of Full Text Index vs. Clustered Index.
The Full Text Index has the purpose of being accessible outside of the database so users can query the tables and columns it needs while being linked to other databases and tables within the SQL Server instance. Is the Full Text Index similar to the global variable in programming where the scope lies outside of the tables and database itself?
I understand the clustered index is created for each table and most likely accessed within the user schema who have access to the database.
Is this correct?
I am kind of confused on why you would use full text index as opposed to clustered index.
One of the major syntax inside the SELECT statment is ..
WHERE FIELDA IN (SELECT PARAVALUE FROM PARATABLE WHERE SESSIONID = "XXXXX" AND PARATYPE='A') AND WHERE FIELDB IN (SELECT PARAVALUE FROM PARATABLE WHERE SESSIONID = "XXXXX" AND PARATYPE='B') AND WHERE FIELDC IN (SELECT PARAVALUE FROM PARATABLE WHERE SESSIONID = "XXXXX" AND PARATYPE='C') AND WHERE FIELDD IN (SELECT PARAVALUE FROM PARATABLE WHERE SESSIONID = "XXXXX" AND PARATYPE='D') AND WHERE FIELDE IN (SELECT PARAVALUE FROM PARATABLE WHERE SESSIONID = "XXXXX" AND PARATYPE='E') AND WHERE FIELDF IN (SELECT PARAVALUE FROM PARATABLE WHERE SESSIONID = "XXXXX" AND PARATYPE='F')
(It's to compare the field content with some user input parameter inside a parameter table... )
I think properly is that the SELECT ... IN is causing much slowness in the sql statement. I have indexed FIELDA , FIELDB, FILEDC etc and those PARAVALUE and PARATYPE in the PARATABLE table. But perfromance is still slow and execution takes >20 seconds for 200000 rows of records.
Do any one know if still any chance to improvide the performance like this?
I'm trying to find whether there is a dmv or system view that can help me see the last time an index was rebuilt or created. Assuming I rebuilt an index using tsql commands (not a job with a history), is there a way to find out the last time that index was rebuilt?
SELECT a.AssetGuid, a.Name, a.LocationGuid FROM Asset a WHERE a.AssociationGuid IN ( SELECT ada.DataAssociationGuid FROM AssociationDataAssociation ada WHERE ada.AssociationGuid = '568B40AD-5133-4237-9F3C-F8EA9D472662')
takes 30-60 seconds to run on my machine, due to a clustered index scan on our an index on asset [about half a million rows]. For this particular association less than 50 rows are returned.
expanding the inner select into a list of guids the query runs instantly:
SELECT a.AssetGuid, a.Name, a.LocationGuid FROM Asset a WHERE a.AssociationGuid IN ( '0F9C1654-9FAC-45FC-9997-5EBDAD21A4B4', '52C616C0-C4C5-45F4-B691-7FA83462CA34', 'C95A6669-D6D1-460A-BC2F-C0F6756A234D')
It runs instantly because of doing a clustered index seek [on the same index as the previous query] instead of a scan. The index in question IX_Asset_AssociationGuid is a nonclustered index on Asset.AssociationGuid.
The tables involved:
Asset, represents an asset. Primary key is AssetGuid, there is an index/FK on Asset.AssociationGuid. The asset table has 28 columns or so... Association, kind of like a place, associations exist in a tree where one association can contain any number of child associations. Each association has a ParentAssociationGuid pointing to its parent. Only leaf associations contain assets. AssociationDataAssociation, a table consisting of two columns, AssociationGuid, DataAssociationGuid. This is a table used to quickly find leaf associations [DataAssociationGuid] beneath a particular association [AssociationGuid]. In the above case the inner select () returns 3 rows.
I'd include .sqlplan files or screenshots, but I don't see a way to attach them.
I understand I can specify to use the index manually [and this also runs instantly], but for such a simple query it is peculiar it is necesscary. This is the query with the index specified manually:
SELECT a.AssetGuid, a.Name, a.LocationGuid FROM Asset a WITH (INDEX (IX_Asset_AssociationGuid)) WHERE a.AssociationGuid IN ( SELECT ada.DataAssociationGuid FROM AssociationDataAssociation ada WHERE ada.AssociationGuid = '568B40AD-5133-4237-9F3C-F8EA9D472662')
To repeat/clarify my question, why might this not be doing a clustered index seek with the first query?
Found out a while back that my facts-tabel has an non-clustered index on its facts_id. In a bunch of procedures an update is executed against a facts_id unfortunately on it's facts-table. I was wondering if changing it into a clustered index is worth the effort / would make sense considering a +110 million facts and re-indexing the other indexes as well? Facts are loaded sequentially, so I would suspect them facts are in the ordered already?
I have a job that runs each night that deletes all records from a table that are older than two weeks old. Is there some way I can view how many records were deleted from the table each night. Is it written to a log somewhere? Thanks in advance!
Hi all, This is my first thread here. I got an information about SET NO_BROWSETABLE ON/OFF in your forum.. The replier told that this is an undocumented option. My question is how you guys find information on such undocumented things....
I am trying to get job information and have a query set up. However, I would also like to get the owner information. However, the job only stores the sid of the owner. Does anybody know how I could change this query to get the owner name instead of sid? Don't want to use the sp_help_job command.

Hi!This is a very simple question and I'm sure you guys will help me a lot.I'm using Visual Basic 2005 for programming. I have one table on my MS SQL 2005 database that has an int column with a counter that needs to be incremented when a user registers.So when reading the value I use a simple SQL query like this: SELECT counter FROM companies WHERE company=0 then I store the value in a local int variable and then I increment it. Then I update the incremented value. UPDATE companies ... I need every single customer to have an individual value. My question is how can I prevent an error, data corruption or whatever if two or more users want to register at the same time? I've been reading about lock update but I'm not sure how to implement it on Visual Basic 2005 and I don't want to store scripts on SQL Server. I'll appreciate your comments and help on this situation.
Hi, I have a problem here in my SQL Server Database. I want to find which trigger is working backend affecting my table input. Since the original author of this trigger was somebody else, I am not able to find the trigger information A simple line of syntax would be great. Thanks in advance sandeep
I am doing an audit of user information in our database and was wondering if there is a way for me to see the last time a user logged into the database. I am using a SQL Server 7.0 box. Any Information would be greatly appreciated. Thanks!
Hi, In my database one user is aliased like a guest. When i run sp_helpuser on the particular database it is giving following result.
username login name database -------- ----------- -------- aaaa NULL XYZ
NOrmally we fill see like this for GUEST User. Now i want to drop this user 'aaaa' only. IF i use sp_dropuser 'null' i think guest user will also drop from XYZ database. So can anyone pls suggest me how to drop this user. I have to add a same user with full permissions. i know in 65 we have sysalternates table gives all alias information. Is there any table gives the same information in sql7. Pls suggest me regarding this.
I administering SQL server and one of or Db (size ~7 Gb) have a table with size 396 MB and 25 indexes created on this one. We working with this DB using Siebel Call center. I have met a very strange situation: when I tried to get some data (using Siebel) my request take ~5 min. I run Profiler and catched this T-SQL statement which Siebel send to SQL server. After that, I run this T-SQL query using Query Analyser and found that Query Optimiser used wrong index. (clustered index) and try to compare every 470436 rows from the tables. This is the statement. @P1, @P2, and @P3 just variable which siebel transfer to SQL server.
SELECT ........ FROM dbo.S_EVT_ACT T1 LEFT OUTER JOIN dbo.S_CONTACT T2 ON T1.TARGET_PER_ID = T2.ROW_ID WHERE ((T1.APPT_REPT_FLG != @P1 OR T1.APPT_REPT_FLG IS NULL) AND (T1.TEMPLATE_FLG != @P2 OR T1.TEMPLATE_FLG IS NULL)) AND (T1.SRA_DEFECT_ID = @P3)
But I found the very strange situation - when I manualy put the value '1-FRK' instead of @P3 - Query Optimizer used RIGHT index and I had a very good performance.
And addition when I tried to run the first Query on the same table but with the only 1000 rows the Query Optimiser choose right index.
Wat's on, wat happend with My Query Optimizer? Wy his decision so different from time to time?
Thank's a lot for any information about how to make Optimiser obedient.
