Constructors

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.

Declaration

public ColumnAttribute()

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.

Declaration

public ColumnAttribute(string name)

Parameters

Type	Name	Description
string	name	The name of the column in the database to map this property or field to.

Properties

Name

The column name in the database this property or field maps to.

Declaration

public string Name { get; }

Property Value

Type	Description
string

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.)

Declaration

public Type Type { get; set; }
