_Campaign Enterprise is designed to work directly with any ODBC (Open Database Connectivity) compliant database. Examples of ODBC databases include SQL Server, MySQL, Oracle, DB2, and most other true relational databases. Campaign also connects directly to MS Access database .mdb or .accdb files. ACT is not a true database, is not ODBC compliant and does not directly interface with Campaign Enterprise.
In order for Campaign to communicate with a database, you must set up a database connection on the computer on which Campaign is installed. There are two types of connections you can use:
An ODBC connection is set up in your operating systems control panel. To create a new ODBC connection, find your control panel either through the start menu or using the search feature.
64 Bit vs. 32 Bit Systems
A problem arises if your Campaign is built on a 64 bit operating system. The Data Sources section in the Administrative tools of the control panel uses 64 bit drivers, which do not show up in the Datasource edit screen. Campaign will only use 32 bit drivers. There are two options to avoid this problem, build 32 bit drivers, or use an OLE DB connection string.
Adding a 32 Bit DSN
Microsoft has hidden the 32 bit Data Sources (ODBC) tool to make it more difficult to find, even though there are plenty of uses for 32 bit drivers. Some of the locations may include:
Using an OLE DB Connection String
There is no clear definition as to what OLE DB stands for, but it is an alternative database connection option to using an ODBC connection. OLE DB strings are typically more functional, less restrictive, faster, and more configurable. These connections can use native clients already included in the operating system or clients you download and add. The primary resource for these types of connections is Connectionstrings.com. Some of the strings you will find on that page include:
If you are using a MS Access database, you can simply browse to the file in the directory. The database must be on the same drive on which Campaign is installed in order to work properly. If your table uses linked tables, those are not available for the write back features used by Campaign.
Regardless of the type of database you use, there is a way to connect it to Campaign to take full advantage of all the write back features available. Make sure that the connection method you use allows for updating the database.
If your OLEDB driver is not loaded on the CE computer, you have to download it and install it (making sure you get the correct 32 or 64 bit version) download it here
Then scroll down to "Microsoft SQL Server 2008 Native Client"
if CE is on a 32 bit machine, then download the x86 package
and install it.
