I use Matlab's Database Toolbox to extract data from a SQL Server database. Today the database admin created a new table, but I can't seem to access it. The new table contains a schema called dbo, and when I try to access it using Matlab's querybuilder tool, the tool gives the following error:
Unable to get table information from data source
I can access other tables in the database without a problem. Any idea what is causing this problem? I don't have enough familiarity with SQL to diagnose it.
Have the admin check that this new table has the same permissions and attributes of a table that you know is working. If the permissions are messed up, you would not be able to retrieve metadata about it.

I'm trying to make a query in Access 97 point to a different database. I cannot find out how to change the db.
I've tried adding another odbc connection but it doesn't give me the option to choose it when running the query.
I've tried to create another query but it still has the old db tables and i cannot choose the new db tables.
Any suggestions would be much appreciated.
thanks,

Try viewing the SQL source of your query. Is the old database name there? Can you just replace it and save your change? Another option would be to point your existing ODBC connection to the new database.
when you add another ODBC database Access will give you the option to add tables from it. You'll need to add whichever tables you need or you won't be able to access them via design view.
You can always use the Connection object to dynamically connect to any DB.
I'm trying to create a Penaho Dashboard using CDE and I have problems accessing my Data.
I have found tutorials but they always use SampleData or Steel Wheels. I have managed to do that myself, but I need to access my own database.
I was able to connect with my oracle database from the Data Source manager and created my own Data Source. But now I don't know how to access those tables from CDE. If I chose "sql datasource" I see the SampleData datasource and can do queries on it, but not the one I created with my database.
So, once I create a connection with my orcale database, how do I access my tables from CDE?
Thanks
There are two options:
SQL over JDBC: you define the db host, port, name, username and password;
SQL over JNDI: it'll use a registered JNDI from the Pentaho platform.
The JNDI field is an auto-complete field and fills in the various available options. However, if your newly created connection doesn't show up there, don't worry. Just type it in, it'll work.
you have to setup your data-source..
Click on datasources-panel on right corner
Click on sql Queries from the list you have seen on left side.
then click on sql over sqljndi
now here in properties in jndi set your database connection you want to access.
you can-not see the out-put of particular query in CDE for that open the same file in CDA for checking particular query's result(which you can find under files section).
Background: I have an .mdf database containing some numeric values that I need to change (specifically, scale and offset values for sensors). The database was created by a Visual Basic program that controls some lab equipment and stores pertinent data in the .mdf file. Please excuse my rudimentary knowledge of the topic; I'm a complete novice when it comes to SQL Server and VB.
After searching through many posts, I understand that to open the .mdf file, you must "attach" it in Microsoft Server Management Studio (I'm using that with SQL Server 2005), which I have successfully done.
Problem: It seems that this only allows me to view and modify the structure of the database, ie. tables, columns, data types etc., rather than the values of the database itself.
Is there a way to do this manually, like how you can edit the field data of .mdb files in MS Access? Again, sorry for my limited knowledge on the topic. I'll gladly provide extra details where needed.
You mention you want to use access. That can be done. Your database is up and running after attaching it.
In Access you can simply create an ODBC connection in access and use Access to edit/modify your data as much as you want. you can also create queries.
It is in the menu item "external data" [I'm guessing because I use a dutch version]. You select to create a "linked table", choose your server and you are done.
Right-click on the table you want to modify in SSMS and select "Edit Top 200 Rows".
If you have more than 200 rows to edit, you can connect to the SQL Server database with either Access or Excel.
Here are the instructions for Access:

I am looking for some help on retrieving Access 2007 database schema information for system object tables. I have reviewed, read and tested this successfully for the non system tables. The database tables info I am trying to retrieve are in the tables that begin with MSys{xxxxxxxxxx} and store things like relationships, creation date, dateupdate, etc. This tables are viewable by right clicking on the Navigation Options popup menu in Access and selecting Show System Objects.
For clarification, I have added the System.mdw database to the connection string, and I have attempted multiple settings in the restrictions property of the getSchema method. I am using ado.net, vb.net, and VS2008, these are access 2007 databases not mdb files.
My issue appears to continue to be no read access to the System tables. My end goal is to manage relationships initially and eventually hopefully script these databases much like can be done EASILY (Microsoft) in SQL Server Mgmt Studio.
I am hoping someone can point me to some good web link resources or even a good book that clearly discusses this functionality.
thanks,
As it turns out the easiest way to gain access to the system table data is to execute a permissions command on the Systems database table(s). The following query did the trick....
Dim strDdl As String = "GRANT SELECT ON MSysObjects TO Admin;"
Dim command12 As New OleDbCommand(strDdl, connection)
I am using WSS 3.0 and trying to restore a mdf. I attached the database in SQL Management Studio, created a new web application, and associated the database to it. When I go into Central Administration-> Application Management -> Content Databases I see the WSS_Content and it says Sites: 2. One of the sites looks more similar to the other. I was able to log into the Sharepoint web app that has the db attached to it, and while it gives me the basic structure of the backed up site, the content of lists is blank, that was the data I was really after (Announcements, tasks, etc exist as lists but are empty). How do I get access to this?
Kindly remove your old database and make newly added database as a default/only database for your webapplication
I'd link to the the data from SQL Server into an Access database.. and then use MS Access to write these values back into sharepoint.
I've written a LOT of data to sharepoint using MS Access.. and I love the functionality.
the data is in SQL server.. but it's got different guids, or it's not wired up from what I'd assume.
You have the data posted to the SQL Server instance.. I'd just link to it in MS Access, write a couple of queries.. recreate a couple of lists.. and then push it from queries based on Access linked tables (to sql server).. and then jam it into Access linked tables (to sharepoint).
Open Access. right-click link basically. times two. and write a couple of queries.
If it was me, and it was just a couple of lists, I'd do this in a couple of minutes I swear.
