復制代碼 代碼如下:

string sql;sql = " set identity_insert dbo.AppUsers on "
+ " insert dbo.AppUsers (Id, IsLocked, IsMustChangeLocalPassword, IsAvailable, Name, Sequence, CreatedBy, CreatedTime, UpdatedBy, UpdatedTime) "
+ " values (0, 1, 0, 0, '[SYSTEM]', 0, 0, GetDate(), 0, GetDate()) "
+ " set identity_insert dbo.AppUsers off "
+ " DBCC CHECKIDENT ('dbo.AppUsers', RESEED, 0) ";
db.Database.ExecuteSqlCommand(sql);

復制代碼 代碼如下:

NO_AUTO_VALUE_ON_ZERO affects handling of AUTO_INCREMENT columns. Normally, you generate the next sequence number for the column by inserting either NULL or 0 into it. NO_AUTO_VALUE_ON_ZERO suppresses this behavior for 0 so that only NULL generates the next sequence number.
This mode can be useful if 0 has been stored in a table's AUTO_INCREMENT column. (Storing 0 is not a recommended practice, by the way.) For example, if you dump the table with mysqldump and then reload it, MySQL normally generates new sequence numbers when
it encounters the 0 values, resulting in a table with contents different from the one that was dumped. Enabling NO_AUTO_VALUE_ON_ZERO before reloading the dump file solves this problem. mysqldump now automatically includes in its output a statement that enables NO_AUTO_VALUE_ON_ZERO, to avoid this problem.

復制代碼 代碼如下:

sql = " SET SESSION sql_mode='NO_AUTO_VALUE_ON_ZERO'; insert AppUsers (Id, IsLocked, IsMustChangeLocalPassword, IsAvailable, Name, Sequence, CreatedBy, CreatedTime, UpdatedBy, UpdatedTime) "
+ " values (0, 1, 0, 0, '[SYSTEM]', 0, 0, CURRENT_TIMESTAMP, 0, CURRENT_TIMESTAMP) ";
