Public Sub New ()

Examples

The following example creates an OracleDataAdapter and sets some of its properties.

Public Sub CreateOracleDataAdapter()  
    Dim myOracleConnection As OracleConnection = New OracleConnection("Data Source=Oracle8i;Integrated Security=yes")  
    Dim custDA As OracleDataAdapter = New OracleDataAdapter

Remarks

When you create an instance of OracleDataAdapter, the following read/write properties are set to their default values, as shown in the table.

Properties	Default value
MissingMappingAction	`MissingMappingAction.Passthrough`
MissingSchemaAction	`MissingSchemaAction.Add`

You can change the value of any of these properties through a separate call to the property.

Applies to

}

Remarks

This implementation of the OracleDataAdapter constructor sets the SelectCommand property to the value specified in the selectCommand parameter.

When you create an instance of OracleDataAdapter, the following read/write properties are set to their default values, as shown in the table.

Properties	Initial value

MissingSchemaAction	`MissingSchemaAction.Add`

You can change the value of any of these properties through a separate call to the property.
