About ColdFusion database drivers
Installing the OLE DB provider
Before you configure an OLE DB data source, you must have installed a recent
version of the Microsoft Data Access Components (MDAC). MDAC includes two OLE
DB providers—SQLOLEDB and MSDASQL. For Access databases, Microsoft makes
available a Jet provider. For SQL Server, Microsoft offers MSDASQL and SQLOLEDB
providers.
During its installation process, ColdFusion attempts to detect the MDAC version on
your computer. If MDAC is absent or the identified version is 2.0 or earlier,
ColdFusion installs MDAC version 2.5 and restarts the installation process. If you
install MDAC on a Windows NT system, you get the MSDASQL and SQLOLEDB
providers.
For updated versions of MDAC, visit the Microsoft Universal Data Access Download
Page at http://www.microsoft.com/data/download.htm/.
Note
Before you install MDAC, stop all unnecessary services, such as Web servers, virus
scanning programs, or mail servers.
You should be aware of the following characteristics in how ColdFusion handles OLE
DB:
The initial driver drop-down list box does not display all of the installed OLE DB
providers. If you are creating a data source using a provider other than
SQLOLEDB or Jet, such as MSDASQL or a MERANT OLE DB driver, you must
select other from the drop-down list box.
No matter which provider you select from the drop-down list box, you must still
retype its name in the Provider field.
When using MSDASQL, you must have an ODBC data source already defined for
the database. Enter this ODBC DSN in the ProviderDSN text box.
