在其他数据库中重新设定身份列（不在当前使用的数据库中）

Question

I would like to reseed identity column in a table, but not in the database which is currently in use.

This works:

use database;
DBCC CHECKIDENT ('table', reseed, 0);

But, I want to do something like this:

DBCC CHECKIDENT (database.[dbo].table, reseed, 0); -- works not

Answer 1

EXEC database.sys.sp_executesql N'DBCC CHECKIDENT(N''dbo.table'', reseed, 0);';

Or even:

DECLARE @t nvarchar(513) = N'dbo.table';

EXEC database.sys.sp_executesql 
   N'DBCC CHECKIDENT(@t, reseed, 0);', 
   N'@t nvarchar(513)', @t;

Also, if the table is empty and does not have any FK references or other limitations , you can do this easier using...

TRUNCATE TABLE database.dbo.table;

...which happens to also reseed the IDENTITY column.

Answer 2

使用 EXEC 执行 USE 和 CHECKIDENT 怎么样？

EXEC('USE database;DBCC CHECKIDENT (''dbo.table'', reseed, 0);')
