An ADO connection manager enables a package to connect to ActiveX Data Objects (ADO) objects, such as a recordset. This connection manager is typically used in custom tasks written in an earlier version of a language, such as Microsoft Visual Basic 6.0, or in custom tasks that are part of an existing application that uses ADO to connect to a data source.

When you add an ADO connection manager to a package, Microsoft SQL Server Integration Services creates a connection manager that will resolve to an ADO connection at run time, sets the connection manager properties, and adds the connection manager to the Connections collection on the package. The ConnectionManagerType property of the connection manager is set to ADO.

You can configure an ADO connection manager in the following ways:

• Provide a specific connection string configured to meet the requirements of the selected provider.
  
• Depending on the provider, include the name of the data source to connect to.
  
• Provide security credentials as appropriate for the selected provider.
  
• Indicate whether the connection that is created from the connection manager is retained at run time.
  

Troubleshooting the ADO Connection Manager

---

When being read by an ADO connection manager, certain SQL Server date data types will generate the results shown in the following table.

SQL Server Data type	Result
time, datetimeoffset	The package fails unless the package uses parameterized SQL commands. To use parameterized SQL commands, use the Execute SQL Task in your package. For more information, see Execute SQL Task and Working with Parameters and Return Codes in the Execute SQL Task.
datetime2	The ADO connection manager truncates the millisecond value.

Note:
For more information about SQL Server data types and how they map to Integration Services data types, see Data Types (Transact-SQL) and Integration Services Data Types.
