EnumIdentityRangeInfo Method

未來的 Microsoft SQL Server 版本將移除這項功能。請避免在新的開發工作中使用這項功能，並規劃修改目前使用這項功能的應用程式。

The EnumIdentityRangeInfo method returns a QueryResults object that enumerates identity range information about articles based on a table.

語法

object
.EnumIdentityRangeInfo( )
as 
QueryResults

Parts

• object
  Expression that evaluates to an object in the Applies To list

Prototype (C/C++)

HRESULT EnumIdentityRangeInfo(LPSQLDMOQUERYRESULTS *ppResults);

Returns

A QueryResults object that contains one result set defined by these columns.

Column	Data type	Description
auto_identity_support	bit	If already replicated, whether an automatic identity range is assigned.
current_identity	big_int	Current identity value.
identity_increment	integer	Amount by which the identity value is incremented.
max_identity	big_int	Maximum boundary of the identity range.
next_starting_seed	big_int	If automatic identity range is enabled, indicates the starting point of next range.
publisher_range	big_int	Publisher identity range size.
replicated	bit	Whether the table is already replicated as an article in another publication.
subscriber_range	big_int	Subscriber identity range size.
threshold	integer	Identity range threshold percentage.

備註

A table may contain only one identity column. If adding the table to a new publication, it may be neither possible nor necessary to assign an identity range to the Publisher or Subscriber automatically. If the table is also used in other publications, EnumIdentityRangeInfo returns information about whether the identity range was assigned.

[!附註]

If an application calls EnumIdentityRangeInfo on an instance of SQL Server version 7.0, the constant, SQLDMO_E_SQL80ONLY, and the message "This property or method requires Microsoft SQL Server 2000 or later" are returned.
