DB Engine :: Retrieving Table And Index Object Definitions In Server
Jul 20, 2015
I am currently investigating the best way to handle partition swapping where the partition scheme is built on several file groups. In order to swap partitions, both partitions need to be on the same file group. In addition, the file groups and partitions are automatically updated once a month meaning that there is a scheduled job that adds a new file group, file group files, and updates the related partition objects.If I am forced to create a new non-partition table on the same file group as the partition of the target table, what would be the best way to create the target table without hard coding the full table definition and clustered index? I know that I can query the systables and syscolumns views to reconstruct a basic SQL statement to build the table definition and views Is there a SQL Server function that I can use to just give me the object definitions? Unfortunately, the OBJECT_ DEFINITION function doesn't apply to tables or indexes. URL....
I was wondering if there is an easy way to get a database schema out of a MS SQL 7 database indicating specs on each field (datatype,length,table it resides in, whether it allows nulls, default values, primary keys, foreign keys, etc.)
Hi There,This is related to a ms access database but since I use the SqlDataSource control I thought I should post here.I have a project that I was working on with this ms access db and using sql controls, everything was working just finesince one day I started getting "Object reference not set to an instance of an object" messages when I try to designa query or retrieve a schema, nothing works at design time anymore but at runtime everything is perfect, its a lotof work for me now to create columns,schemas and everything manually, I've tried reinstalling visualstudio, ado componentsbut nothing seems to fix it, did this ever happen to any of you guys?any tip is really appreciated thanks a lot
I have one partition table "tablea" with partition key dateentry on yearly basis and table have four partition with name y2013,y2014,y2013,y2015 with one partition schema . How I can create partition index on tablea that first time create partition  index  and next time I want to rebuild index only on y2015 partition .Â
I have a problem with multiple databases on a server. I originally read another post that went into detail on this same error. After reading the post I decided to re-index the table to see if that would fix my issue. I started on Saturday by re-indexing a table on database 'a' - the process completed after that; I received another error on database 'b' on Monday i subsequently re-indexed all indexes on this database; today I have received the same message on database 'c' and 'd'. All post that I have read seem to point to an issue with only one database and not multiple databases. I have approximately 100 databases on this cluster - SQL 2000. The physical server logs only error shown is '000009ac.00001744::2007/12/29-15:12:58.848 ERR [CP] CppReadCheckpoint unable to copy file U:Disk12Partition1d61e68e-a60f-4ca6-b9ae-df3b893e4bb2 0000001.CPT to C:DOCUME~1mscsLOCALS~1TempCLS302F.tmp, error 3 000009ac.00001744::2007/12/29-15:12:58.848 ERR [CP] CppReadCheckpoint - Was that due to quorum resource not being up ??? ' before corruption of database 'a'.
Here is the entire error if you think it will help. The error has been the same on all databases: 12/28/2007 6:23 AM A possible database consistency problem has been detected on database ‘ substituted_name'. DBCC CHECKDB and DBCC CHECKCATALOG should be run on database 'substituted_name'..
When I run the DBCC CHECKDB command I got these errors on Substite name database: DBCC results for 'FVD_A'. Msg 2511, Level 16, State 1, Line 1 Table error: Object ID 165575628, Index ID 2. Keys out of order on page (1:12743984), slots 97 and 98. There are 72920059 rows in 2281375 pages for object 'FVD_A'. CHECKDB found 0 allocation errors and 1 consistency errors in table 'FVD_A' (object ID 165575628). DBCC results for 'FVD_CVS322'.

I am at a loss. I believe we may have a bigger issue, but the SAN Administrator and Server Admin are saying there is nothing they can do. Do I have a true SQL Server issue or something else.
Where can i find more information on the table definitions? I am trying to understand the definition of User.AuthType & User.UserType. There should be some sort of documentation somewhere.
When I add a user to a report or folder it will assign it to UserType = 1, AuthType = 3. I have no idea what that means.
I have merge replication between sql 2005 SP1, and when I disable distribution from my publisher, my tables with identity columns change the property "Not for replication" to "NO", does somebody knows if this is a known problem ?
Other information : the compatibilty level for database is 2000.
I have nine type of buttons, EnrollAmtBTM PlacAmtBTM and so on, I also have a SQL setver view V_Payment_Amount_List from here i need to display the data on the button this is the select value to display when i choose the agency list and the amount corresponding to that agency_ID is displayed here the agency_ID is fetched from the SQL CONDITION THIS IS WHERE I GET FETCH AGENCY DATA WHEN SELECTED i.e SQL CONDITIONprotected void CollectAgencyInformation() { WebLibraryClass ConnectionFinanceDB;ConnectionFinanceDB = new WebLibraryClass(); string SQLCONDITION = "";string RUN_SQLCONDITION = ""; SessionValues ValueSelected = null;int CollectionCount = 0;if (Session[Session_UserSPersonalData] == null) {ValueSelected = new SessionValues(); Session.Add(Session_UserSPersonalData, ValueSelected); } else { ValueSelected = (SessionValues)(Session[Session_UserSPersonalData]); }ProcPaymBTM.Visible = false;PaymenLstBTN.Visible = false; Dataviewlisting.ActiveViewIndex = 0;TreeNode SelectedNode = new TreeNode(); SelectedNode = AgencyTree.SelectedNode; SelectedAgency = SelectedNode.Value.ToString(); Agencytxt.Text = SelectedAgency; Agencytxt2.Text = SelectedAgency; Agencytxt3.Text = SelectedAgency;DbDataReader CollectingDataSelected = null; try {CollectingDataSelected = ConnectionFinanceDB.CollectedFinaceData("SELECT DISTINCT AGENCY_ID FROM dbo.AIMS_AGENCY where Program = '" + SelectedAgency + "'"); } catch { }DataTable TableSet = new DataTable(); TableSet.Load(CollectingDataSelected, LoadOption.OverwriteChanges);int IndexingValues = 0;foreach (DataRow DataCollectedRow in TableSet.Rows) {if (IndexingValues == 0) {SQLCONDITION = "where (Project_ID = '" + DataCollectedRow["AGENCY_ID"].ToString().Trim() + "'"; } else {SQLCONDITION = SQLCONDITION + " OR Project_ID = '" + DataCollectedRow["AGENCY_ID"].ToString().Trim() + "'"; } IndexingValues += 1; }SQLCONDITION = SQLCONDITION + ")"; ConnectionFinanceDB.DisconnectToDatabase();if (Dataviewlisting.ActiveViewIndex == 0) { Dataviewlisting.ActiveViewIndex += 1; } else { Dataviewlisting.ActiveViewIndex = 0; } SelectedAgency = SQLCONDITION; ValueSelected.CONDITION = SelectedAgency;
???? this is where i use to get count where in other buttons and are displayed.... but i changed the query to display only the Payment_Amount_Budgeted respective to the agency selected. from the viewRUN_SQLCONDITION = "SELECT Payment_Amount_Budgeted FROM dbo.V_Payment_Amount_List " + SQLCONDITION; try { CollectionCount = ConnectionFinanceDB.CollectedFinaceDataCount(RUN_SQLCONDITION); EnrollAmtBTM.Text = CollectionCount.ToString(); } catch { }////this is my CollectedFinaceDataCount-- where fuction counts the records in the above select statement if i use for eg. "SELECT Count(Placement_Retention_ID) FROM dbo.V_Retention_6_Month_Finance_Payment_List" here is the functionpublic int CollectedFinaceDataCount(String SQLStatement) {int DataCollection; DataCollection = 0; try { SQLCommandExe = FinanceConnection.CreateCommand(); SQLCommandExe.CommandType = CommandType.Text; SQLCommandExe.CommandText = SQLStatement; ConnectToDatabase();DataCollection = (int) SQLCommandExe.ExecuteScalar(); DisconnectToDatabase(); }catch (Exception ex) {Console.WriteLine("Exception Occurred :{0},{1}", ex.Message, ex.StackTrace.ToString()); } return DataCollection; }
So here mu requirement request is to display only the value fronm the view i have against the agency selected Please help ASAP Thanks Santosh
if I create an index for a table with some records, do you think I can retrieve records in a giving range? for example, the 5th to 10th records?Possible? How can I do it?When we insert data at the table, would the index in sequential order? How would the index be created for new inserted records?I'm using SQL 2005 Express, not SQL 2000.
Is there a way of uploading column definitions from the Flat File Connection Manager into a SQL Server table definition. Since I have over a dozen data sources to process each with around 200 columns and of course like many BI techies I have little immediate influence over the structure of these flat files. I just know that these data sources are business critical.
Judging by looking at similar threads I can't be the only one who would greatly benefit from being able to upload column definitions from the Flat File Connection Manager into a SQL Server table definition as opposed to doing this manually.
Hi All, In SQL Server 7, we had the option of opening a previously saved trace template and running it inorder to run a previously saved trace defintion repeatedly. File > Open > Trace Definition and choosing the Trace Name. Clicking OK would run the trace.
How do we do the same in SQL Server 2000? File > Open > Trace Template opens a Trace template but has only a 'Save' button and I'm therefore unable to run it.
How is it possible to run a previously defined trace repeatedly in SQL server 2000? Thanks in advance, Praveena
I have a new instance (SQL 2012) and I am trying to create a cube but it retrieves the error: Either the 'NameUser' user does not have permission to create a new object in 'NameServer' or the object does not exist. I am not the DBA but I got privilege as administrator in my instance. I even checked the propierties (right click on the analysis service instance) and in security there is my name as well..
Since couple of days, I am getting a very weird problem on my production environment. Basically, any index operation [rebuild, drop] etc. against an index on a table is getting blocked by [Sleeping,Dormant] connections.
Scenario: I have a Table TableX in database DBX on Server X. This table has a Non-unique, non-clustered index on a NVARCHAR column. This table is accessed by SQL written in a store procedures from Server A via a link server. Both the Servers are SQL 2008 R2 edition.
If I try to run any operation on the index, it get blocked by existing session and keeps on getting blocked by different sessions. Yesterday it was blocked for about 13 hours before I killed the session.
Executing sp_WhoisActive shows few sessions with Host Server A without any sql_text. These sessions actually blocked the indesx operation on the ServerX. These sessions always exist. Sessions details are
I need to setup log shipping from a 2008 Standard to a 2012 Standard server. I have not found any restrictions for this, however, when I want to connect to the 2012 server on the add secondary server page, I receive the following error:'Index was outside the bounds of the array. (Microsoft.SqlServer.Smo)'.
Create Index ind_Item_Name on Item(I_Name); Create Index ind_Item_BC on Item(I_BC); Create Index ind_Item_Company on Item(I_Company); Create Index ind_Item_CompanyFound on Item(I_CompanyFound); create Index ind_Item_i1 on Item(I_Company,I_CompanyFound); create Index ind_Item_i2 on Item(I_CompanyFound,I_Company);
Now this query DOES NOT use index: select I_Name, I_Code, I_MatID, I_BC, I_Company,I_Info1, I_Acquired, I_CompanyFound, 0 as I_Found from Item where (I_Company='102' or I_CompanyFound='102' )
While this one use:
select I_Name, I_Code, I_MatID, I_BC, I_Company,I_Info1, I_Acquired, I_CompanyFound, 0 as I_Found from Item where (I_Company='102' ) UNION select I_Name, I_Code, I_MatID, I_BC, I_Company,I_Info1, I_Acquired, I_CompanyFound, 0 as I_Found from Item where (I_CompanyFound='102' )
Both return the same rows. Is this a bug? I found the following: http://support.microsoft.com/kb/223423
Just wonder if system base tables always use clustered index? I am using SQL Server 2005 and find sys.sysidxstats base table is using heap, not clustered index. Why?
Create Index ind_Item_Name on Item(I_Name); Create Index ind_Item_BC on Item(I_BC); Create Index ind_Item_Company on Item(I_Company);
It is populated with 50 000 records. Searching on indexed columns is fast, but I've run into the following problem: I need to get all distinct companies in the table. I've tried with these two queries, but they both are very slow!
1. "select I_Company from item group by I_Company " - This one takes 19 seconds
2. "select distinct(I_Company) from item" -This one takes 29 secons
When I ran them through the SQL Management Studio and checked the performance plan, I saw that the second one doesn't use index at all ! So I focused on the first... The first one used index (it took it 15% of the time), but then it ran the "stream aggregate" which took 85% of the time ! Actully 15% of 19 seconds - about 2 seconds is pretty much enough for me. But it looks that aggregate function is run for nothing! So is it possible to force the query engine of the SSCE not to run it, since there is actually no aggregate functions in my select clause? According to SQL CE Books online: Group By
"Specifies the groups (equivalence classes) that output rows are to be placed in. If aggregate functions are included in the SELECT clause <select list>, the GROUP BY clause calculates a summary value for each group." It seems the aggregate is run every time, not only when there is an aggregate function.
On our particular database server, we run the Rebuild Index Task (Using classic Maintenance Plan Designer) every night. Running the  script below, I saw that about 77 tables had an avg_fragmentation_in_percentage between 80% and 99% !!
SELECT OBJECT_NAME(ind.OBJECT_ID) AS TableName, ind.name AS IndexName, indexstats.index_type_desc AS IndexType, indexstats.avg_fragmentation_in_percent FROM sys.dm_db_index_physical_stats(DB_ID(), NULL, NULL, NULL, NULL) indexstats INNER JOIN sys.indexes ind ON ind.object_id = indexstats.object_id AND ind.index_id = indexstats.index_id WHERE indexstats.avg_fragmentation_in_percent > 30--You can specify the percent as you want ORDER BY indexstats.avg_fragmentation_in_percent DESC
I dont understand why these tables are highly fragmented after a daily index rebuild! Unless the users are doing heavy inserts/updates/deletes during the day.
I am currently re-writing an overnight index defrag procedure and would like to audit indexes in my database - logging the before defrag action" avg fragmentation value and "after defrag action" frag value in an audit table. Â This will be for all databases on the server. Â I have completed the vast majority of it (cycling though all the databases, detecting which indexes need reorganising or rebuilding and inserting the information into a table) but I cannot get the audit values working properly. Â For example, a sample row in my audit table would look like this:
1. I need to make use of in memory engine for my pr-existed develop procedures ,tables ,index. do I need and code changes for application and how to store tables /indexes in OLTP memory
Assume table index may have primary key index as well.
2. If table with one primary index and 2 foreign constraints, 3 non clusters indexed. which one able o load to memory area and how t do that.
3. In memory is lock free zone. usually locks will happpen in RDMS context . how this works without locks.
We have 3 maintenance jobs configured in this particular DB instance:
Daily backup of system database - SubPlan1 (Check Database Integrity Task --> Rebuild Index Task-->Backup Database Task)Daily backup of user databases - Five subplans for each task : (Check DB integrity --> Rebuild Index -->Backup User Database, Backup Log -->Cleanup History)Weekly maintenance - SubPlan1 (Check Database integrity job (system+user DB)Â + rebuild index job (system+user DB) )
PROBLEM: I just noticed that the User DB Rebuild Index task has been running since the 03/04 and the Weekly maintenance plan - subplan1 since the 12/04.
Which job is "safe" to stop without impacting the database?
I have 1 client who keeps running into the following error on the subscriber and merge agents >
€œCannot insert duplicate key row in object 'MSmerge_genhistory' with unique index 'unc1MSmerge_genhistory'.€?
Last time we got this error I ran a reindex on table MSmerge_genhistory on the publisher database, I then successfully generated a new snapshot and the subscribers started to synchronize again. This time around I keep getting the error even after I follow these steps (I also ran all the jobs to clean up replication). The last time I ran into this error I created a job to reindex msmerge_genhistory on a nightly bases in an effort to avoid this problem. Can somebody please provide me with a workaround and also the reason why this error occurs in the first place.
I have been recently redesigning my tables - creating FK relationships from child tables to the PK userid in the Users table. The specifics of what I did and why can be seen here:
Cannot insert duplicate key row in object 'dbo.lastlogin' with unique index 'IX_lastlogin'. The statement has been terminated.
Or, for that matter, SavedSearches or any other table where I need to insert the same userid twice. I can see why I would want to avoid duplicates in the Users table. But, for lastlogin, savedsearches, and a few of my other tables, the same user may account for multiple rows.
Any suggestions as to where I messed up and how to deal with this?
Thanks.

In the SQL Server 2014 Management Studio's object explorer indexed views with schemabinding don't have an index node. Thus, you can create and drop Indexes for views only via T-SQL. The SQL Server Management Studio 2012 still shows the index node.
Is there some Management Studio setting in version 12.0.2000.8 which I am missing?
Hi, I am wondering using transfer sql server objects task in a sub-package and feeding tableslist property from the parent package. which works fine. problem :
I want to be able to change the name in the fly so if I have TableA I want to copy it for the destination as TableB is there any work arround this just using transfer sql server objects task. Thanks
