System.Object
  System.Attribute
    System.Data.Linq.Mapping.TableAttribute

Namespace:  System.Data.Linq.Mapping
Assembly:  System.Data.Linq (in System.Data.Linq.dll)

[AttributeUsageAttribute(AttributeTargets.Class, AllowMultiple = false, Inherited = false)]
public sealed class TableAttribute : Attribute

The TableAttribute type exposes the following members.

  NameDescription
Public methodTableAttributeInitializes a new instance of the TableAttribute class.
Top

  NameDescription
Public propertyNameGets or sets the name of the table or view.
Public propertyTypeIdWhen implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.)
Top

  NameDescription
Public methodEqualsInfrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.)
Public methodGetHashCodeReturns the hash code for this instance. (Inherited from Attribute.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodIsDefaultAttributeWhen overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.)
Public methodMatchWhen overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

  NameDescription
Explicit interface implemetationPrivate method_Attribute.GetIDsOfNamesMaps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.GetTypeInfoRetrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.GetTypeInfoCountRetrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.InvokeProvides access to properties and methods exposed by an object. (Inherited from Attribute.)

Use this attribute to designate a class as an entity class that is associated with a database table or view. LINQ to SQL treats classes that have the TableAttribute attribute as persistent classes.

LINQ to SQL supports only single-table mapping. That is, an entity class must be mapped to exactly one database table, and you cannot map a database table to multiple classes at the same time.

You can use the Name property of the TableAttribute attribute to specify a name for the table, and you can optionally use the schema name to qualify a table name. If you do not specify a name by using the Name property, the table name is assumed to be the same as the class name.

Schema-qualified Names

You can optionally use the schema name to qualify a table name. By default, the token to the left of the first period in the Name string is considered to be the schema name. The remainder of the name is considered to be the table name. The provider quotes the table name as appropriate. For example, the LINQ to SQL provider for SQL Server makes sure that brackets are used at least where they are needed.

NoteNote

In some cases, you must explicitly quote attributes because the SQL Server provider cannot auto-quote. The following table shows some examples.

Case

Example: Identifier Name

Example: Expected String in Attributes

Otherwise…

Schema name contains a period

Schema: "A.B"

Table: "C"

"[A.B].C"

The first period is assumed to separate the schema name from the table name.

Schema/Table name starts with @

"@SomeName"

"[@SomeName]"

Assumed to be a parameter name.

Schema starts with [ and ends with ]

"[Schema.Table]"

"[[Schema].[Table]]]"

The unquoted identifier resembles a quoted identifier.

Table starts with [ and ends with ]

"[Table]"

"[[Table]]]"

The unquoted identifier resembles a quoted identifier.

[Table(Name = "Customers")]
public class Customer
{
    // ...
}
