mapped.

[AttributeUsageAttribute(AttributeTargets.Property|AttributeTargets.Field)] public class ColumnAttribute : Attribute
The ColumnAttribute type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | ColumnAttribute |
Used with the ExplicitColumns, indicates this property should be mapped and that the column name
is the same as the property or field name.
|
| ColumnAttribute(String) |
Specifies the name of the column in the database to use for this property/field. If the ExplicitColumns
is used on the POCO, also tells the mapper that this column should be included when mapping.

| GetHashCode | Returns the hash code for this instance. (Inherited from Attribute.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| IsDefaultAttribute | When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.) |

 | Name |
The column name in the database this property or field maps to.
|
| Type |
Used to override the Type of the column in the database for INSERTs/UPDATEs. The data in the property/field this attribute is
applied to will be converted to this Type for INSERTs/UPDATEs. If null, the same Type of the property/field will be used
instead. (NOTE: This does NOT affect the Type when fetching/SELECTing data from the database.)
|
| TypeId | When implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.) |
