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

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. |

subscriber_range |
big_int |
Subscriber identity range size. |
threshold |

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.
