注意: |
---|
SQL Distributed Management Objects (SQL-DMO) strings are always returned as OLE BSTR objects. A C/C++ application obtains a reference to the string. The application must release the reference using SysFreeString. |
备注
The format and contents of the UpdateCommand property must match those specified for the @upd_cmd argument of the sp_addarticle system stored procedure. For more information, see sp_addarticle (Transact-SQL).
注意: |
---|
If an application sets UpdateCommand after the initial snapshot has been created, a new snapshot must be generated and then reapplied to each subscription. Snapshots are applied when the next scheduled snapshot and distribution agent run. |
