  • Artikkeli

Applies to: Azure SQL Database Azure SQL Managed Instance

This procedure is scoped to an Active Geo-Replication relationship between a primary and secondary. Calling the sys.sp_wait_for_database_copy_sync causes the application to wait until all committed transactions are replicated and acknowledged by the active secondary database. Run sys.sp_wait_for_database_copy_sync on only the primary database.

sp_wait_for_database_copy_sync [ @target_server = ] 'server_name'
     , [ @target_database = ] 'database_name'

Arguments

[ @target_server = ] 'server_name'

The name of the Azure SQL Database server that hosts the active secondary database. server_name is sysname, with no default.

[ @target_database = ] 'database_name'

The name of the active secondary database. database_name is sysname, with no default.

Permissions

Any user in the primary database can call this system stored procedure. The login must be a user in both the primary and active secondary databases.

Remarks
