Syntax

'Declaration
Public ReadOnly Property HasPrimaryKey As Boolean
    Get
'Usage
Dim instance As ReplicationTable
Dim value As Boolean

property bool HasPrimaryKey {

member HasPrimaryKey : bool

function get HasPrimaryKey () : boolean

Property Value

Type: System.Boolean
A Boolean value. If true, the table has primary key. If false, the table has no primary key.

Remarks

Transactional replication requires a primary key to identify rows. If there is a primary key constraint on one of the columns, the table can be published as an article in a transactional publication as well as in a snapshot and merge publication. If there is no primary key constraint on the table, then it is not possible to publish this table in a transactional publication.

The HasPrimaryKey property can be retrieved by members of the sysadmin fixed server role at the Publisher or by members of the db_owner fixed database role on the publication database.

The HasPrimaryKey property is available with SQL Server 7.0, SQL Server 2000, and SQL Server 2005.

This namespace, class, or member is supported only in version 2.0 of the .NET Framework.
