I am trying to connect to a DBISAM database. This database system is used mostly on Delphi. The table files are stored in a folder.
My question is: Is there a way to connect to these databases from vb.net? How should I go about doing that?
I would recommend purchasing the ODBC driver from Elevatesoft for the version of DBISAM that you are using, and connect via ODBC.

This is my first post in here,
I am new to SQL and I started learning it, I use it mainly in excel to get data from an outer Database
I first go to data then Refresh all then from the menu I choose connection properties
Then a dialogue appears and I input my code in the window called Command text from the Tab Definition
I added images to show where I input my SQL code
My question is what type of SQL do I input there ?
is it mySQL or SQLServer or what ??, so I can learn it, because some commands just don't work with me the way they are supposed to do
You can connect to any database type as long as you have the appropriate ODBC drivers. For example, here is documentation for MySQL for Excel. Quote from article "Use Microsoft Query to retrieve external data":
If the external database that you want to access is not supported by the
ODBC drivers that are installed with Microsoft Query, then you
need to obtain and install a Microsoft Office-compatible ODBC driver
from a third-party vendor, such as the manufacturer of the database.
Contact the database vendor for installation instructions.
OLAP databases do not require ODBC drivers. When you install Microsoft Query, drivers are installed for databases that were created
by using Microsoft SQL Server Analysis Services. To connect to other
OLAP databases, you need to install a data source driver and client
software.
Whichever database type you connect to, you will still be using Microsoft's SQL variant (as developed for SQL Server). As a beginner you're not going to notice too many differences right off the top. Most of the differences are related to data types, such as DATE vs DATETIME. Here is a wiki on SQL Compliance and this article on MS Access SQL will also apply to Excel Query.
You can connect to many data source including: SQL Server database, Access database, MySQL database, PostgreSQL database etc..

I have been trying to figure out how to start with Oracle SQL, but I can't get the "Connection" to work. I'm not sure what the (connection name, username, password, etc.) fields are.
If I want to create a small database on local host, why do I need to connect in the first place.
I searched Google but still can't get it to work. Any help is appreciated.
ERROR MESSAGE: IO Error: The Network Adapter could not establish the connection
SQL Developer is just a client utility that lets you connect to an existing database. It sounds like you don't have a database to connect to yet. If that's the case, you'd either need someone to create a database on another machine for you or you'd need to download the database software on to your local machine and create a database to connect to. You can download the Oracle database from the Oracle Technology Network, the same place you downloaded SQL Developer from. I would guess that you would want to download Oracle 11.2 Express Edition.
Alternately, you may want to download one of the VMs that Oracle has put together that has a lot of related software installed for you to use. For example, this VM has SQL Developer, Oracle 12.1, APEX, XML DB, and a number of labs already installed for you.
Oracle SQL Developer is a tool to ACCESS existing database, you cannot create new database here. The connection is used to define where your existing database sits and how to connect to it. So you need to name you connection (bookmark), provide host name, where database runs and user name plus password to identify yourself.
I have an SQL database and want to connect to it using VBA in order to support some legacy functionality. I'm using an ADODB connection and need to know what my database DSN is. How can I find this?
I'm using SQL Server 2008, thanks! :D
A DSN (data source name) is an indirect way of referring to the database. You have to create them manually (or semi-automatically using a wizard of some kind). Go to ControlPanel->AdministrativeTools->DataSources (ODBC) to see if one has already been defined for the database to which you want to connect.
But I think you might mean "connection string", not "DSN". There are many, many ways to tell ADODB how to find and connect to your database (DSNs are just one of those), but you always need a connection string.
I have often turned to ConnectionStrings.com to help me through the maze of similar-but-not-identical options.
There may not be a DSN. DSNs are not created automatically.
I'm not sure you really mean DSN, as a DSN is an ODBC concept. Still, look in Administrative Tools->Data Sources (ODBC).
I'm getting data as an Access file.
My application uses MySQL/Java. I'd like to parse the Access data, and stick it in MySQL.
Is there a Java tool that will help me do this?
MDB Tools is a set of open source libraries and utilities to facilitate exporting data from MS Access databases (mdb files) without using the Microsoft DLLs. Thus non Windows OSs can read the data.
If this is a one time conversion just use MS-Access, link to your MySQL database tables and use update queries to transfer the data.
If your app needs to import Access data into MySQL on a continuing basis you could connect to Access via ODBC and then have your app write the data to MySQL.
Similar to this question only the other way of flow.
Insert Picture into SQL Server 2005 Image Field using only SQL
I need to be able to save a image field out into the file system and be able to name the file with only using SQL. I don't want to use TEXTCOPY either because I need to use the connection to the database that is running the query itself.
I'd like this to work in SQL 2005 to support older database clients but if it's available in only 2008 that's fine.
Any ideas?
With SQL 2k8 there is the new FILESTREAM type that covers such cases. Filestreams can be opened via the Win32 file access handle like any other file, but hey are integrated into the database from transaction and backup/restore point of view.
I had a similar issue in SQL 2k5 and my solution was to use a CLR stored procedure with EXTERNAL_ACCESS that was writing into the file system using C# file operations.
I don't believe there is a way to save out using only sql, but there is a command-line utility, bcp.
