I have an SQLite connection set up as data source in IntelliJ IDEA Ultimate. How do you ATTACH a separate SQLite database to the connection?
Open Data Source properties -> Option tab -> Enable 'Single connection mode'. Close all sessions in 'Services' tool window, open new console for this data source and try something like this
attach database 'C:\temp\db1.sqlite' as db1;
it will be shown in schemas list as db1.
To persist an attached SQLite database, open the data source "Properties", click the "Options" tab, find the "Connection" section, find the "Startup script:" field, and enter the following:
ATTACH '/path/to/my/second/sqlite.db' AS db2;

I am trying to connect to a SQLiteDB that is on my computer. But could easily be on my workstation. I have created a DNS for it in ODBC with a downloaded driver but I'm stuck on how I can connect to this DB in UIPath.
Drag the Database > Connect activity into your sequence or flowchart
Click on “Configure Settings” and then connection wizard
Select for Data Source and “.Net Framework provider for ODBC” for Data Provider
Click OK
Select the ODBC DSN name
If the database requires a user/password, enter that too.
Then click on test connection, should get a pop up that says "Test Connection succeeded"
What it will output is a Database Connection.
While the focus is on the database connection Activity, go to the output section and in the Database Connection, create the variable (Control K) and name the variable.
From here, you can use the connection and other database activities to manipulate it
In SQL Management Studio, you can query a database table by right clicking it in the object explorer and selecting 'Select XX Rows'. A window opens showing the query and results. The query includes the database and scheme names. This action does not affect the selected database connection in the toolbar's dropdown list.
I use this as a starting point for manually writing queries, and it's quicker to just query the tables. So I regularly change the current database connection to the database I just created the query for.
Is there a way to make the database connection in the toolbar's dropdown list automatically change to the database where you start a query in the object explorer?
This is solved since the release of SSMS 2016.
I am developing a transformation (on pentaho 4.4.0) which basically reads data from one oracle DB (11g), makes some transformation and loads data into another Oracle DB. Now for DB table input/output when I need to select a connection I have to select it from a drop down menu in 'Edit Step'. When I edit the connection, it asks me settings, like Host name, database name, port number, user name, password.
What I want is, to create a text file called 'Pentaho_connection_properties' in some directory on my machine where I will save all these info and as soon as I choose a connection name from the connection drop down menu, Pentaho should automatically read the file and populate the settings corresponding to that connection name. The purpose is to get rid of this manual process to entering settings again and again for multiple use of same DB.
Please let me know how this can be done. I will appreciate if you can be little explicit since I am new to Pentaho.
Thanks
Switch to using database repositories. Connection definitions are shared throughout an entire database repository.
I'm really not a database person, so forgive me if this question.
I'm using Visual Studio 2008 and I am trying to view tables on another server database.
Example:
I have my aspnetdb.mdf database, and my anaylsis.mdf database.
What I am trying to do within Visual Studio is read table columns that are inside aspnetdb.mdf from anaylsis.mdf.
How is this done?
Thanks
In order to have access to any object in other server, you need to create a linked server to that server as below:
in your aspnetdb go to server Objects -> Linked Servers ->Right click -> new linked servers .
a window will be opened that you have to fill the information in the general tab as below:
Linked Server: anaylsisDB
Server Type: otherdata source
Provider: SQL Native Client
ProductName :SQL
Data source: anaylsis(This is the server name which you want to connect to)
After you finished with this tab, in the left side of the page goto secutity tab and fill the information as below:
In the bottom of the page select be made using this secutity content and insert the anaylsis server username and password.
click ok and now you have made a linked server to the anaylsis. so you can use any objects in anaylsis with this format:
anaylsisDB.[Databasename].dbo.[tableName]
or
anaylsisDB.[Databasename].dbo.[ViewName]
Here anaylsisDB is the name of the linked server that we have made to the anaylsis server.
SELECT * FROM [linkedServer].[database].[dbo].[someTable]
You find some usefull information in the T-SQL Documentation on MSDN:
If the table or view exists outside the instance of SQL Serverl, use a four-part name in the form linked_server.catalog.schema.object. For more information, see sp_addlinkedserver (Transact-SQL).

A useful way to do that is to use VIEWS, you create view with DATAS from other databases and use it like a kind of table in your Database..
MSDN
You can either setup a linked server on the the same server you are running the sp on which will give it an alias i.e.
select *
from Server2.Database2.dbo.SomeTable
Or you can use the OpenRowset command. I always try and use the Linked server option although, the OpenRowset is useful if you don't have server admin access.
Both are obviously dependant on the servers being able to communicate ok.
In normal condition, I can add schemas in the dbml file to empty database with code below.
But now when I run this code, I take the error "Cannot drop database "test" because it is currently in use." How can I do it?
Dim db As New UI_Class.UIData
If db.DatabaseExists Then
db.DeleteDatabase()
End If
db.CreateDatabase()
It might happen as your SQL Server Management Studio (SSMS) must be holding it.
Most likely something is connected to the db.
Common causes are:
Some other tool connected
Trying to delete the database you connected to.
Another user connected to the db.
