Examples

    custDA.DeleteCommand.Parameters.Add("pDeptNo", OracleType.Number, 2, "DeptNo").SourceVersion = DataRowVersion.Original;  
}  

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.
