Description
Identifies the data provider you want to use to connect to your data source.
When to specify Provider
You must specify the Provider parameter before connecting to the database.
Applies to
ADO.NET
OLE DB
SNC SQL Native Client for Microsoft SQL Server
MSOLEDBSQL Microsoft OLE DB Driver for SQL Server
Syntax
Provider='provider_name'
Default value
None
Usage
Select a data provider from the list of installed data providers displayed in the Provider drop-down list. For example, if you are using Microsoft's OLE DB Provider for ODBC, select MSDASQL as the Provider value. If you are using Microsoft's OLE DB Provider for SQL Server, select SQLOLEDB as the Provider value.
For more information, see the documentation provided by your OLE DB or ADO.NET data provider.
SNC SQL Native Client driver
The Provider DBParm parameter for the Microsoft SQL Native Client (SNC) interface allows you to select the SNC version that you want to use for a database connection. You can set this parameter in script to SQLNCLI (for the SNC 9.0 driver that connects to SQL Server 2005) or to SQLNCLI10 (for the SNC 10.0 driver that connects to SQL Server 2008) or to SNC 11 (for the SNC 11 driver that connects to SQL Server 2012 or later). Otherwise, you can select one of these providers on the Connection tab of the Database Profile Setup dialog box for the SNC interface.
If you do not set or select a provider, the default selection is SQLNCLI (SNC 9.0 for SQL Server 2005). This allows existing SNC interface users to be able to upgrade to the current release of PowerBuilder without any modifications. If PowerBuilder fails to connect with the SQLNCLI provider, it will attempt to connect to SQLNCLI10 provider. However, if you explicitly set the provider and the connection fails, PowerBuilder displays an error message.
