Property Value

An IDbCommand object that contains a query or stored procedure.

Remarks

Synchronization adapter commands enable you to specify the queries and stored procedures that are used to select from and apply data and metadata changes to a peer database. For more information, see How to: Configure Change Tracking and Synchronize Peers. Each command uses session variables that enable you to pass values during synchronization. These variables are specified like other parameters to queries or stored procedures in ADO.NET commands. For more information, see How to: Use Session Variables for Peer-to-Peer Synchronization.

Example

The following code example creates a command that updates rows in the Customer_Tracking table at a peer. The command is a stored procedure that is defined in Setup Scripts for Sync Services How-to Topics. To view this code in the context of a complete example, see How to: Configure Change Tracking and Synchronize Peers.

SqlCommand updMetadataCustomerCmd = new SqlCommand();
updMetadataCustomerCmd.CommandType = CommandType.StoredProcedure;
updMetadataCustomerCmd.CommandText = "Sales.sp_Customer_UpdateMetadata";
updMetadataCustomerCmd.Parameters.Add("@CustomerId", SqlDbType.UniqueIdentifier);
updMetadataCustomerCmd.Parameters.Add("@" + DbSyncSession.SyncCreatePeerKey, SqlDbType.Int);
updMetadataCustomerCmd.Parameters.Add("@" + DbSyncSession.SyncCreatePeerTimestamp, SqlDbType.BigInt);
updMetadataCustomerCmd.Parameters.Add("@" + DbSyncSession.SyncUpdatePeerKey, SqlDbType.Int);
updMetadataCustomerCmd.Parameters.Add("@" + DbSyncSession.SyncUpdatePeerTimestamp, SqlDbType.BigInt);
updMetadataCustomerCmd.Parameters.Add("@" + DbSyncSession.SyncCheckConcurrency, SqlDbType.Int);
updMetadataCustomerCmd.Parameters.Add("@" + DbSyncSession.SyncRowTimestamp, SqlDbType.BigInt);
updMetadataCustomerCmd.Parameters.Add("@" + DbSyncSession.SyncRowCount, SqlDbType.Int).Direction = ParameterDirection.Output;

adapterCustomer.UpdateMetadataCommand = updMetadataCustomerCmd;

Dim updMetadataCustomerCmd As New SqlCommand()

With updMetadataCustomerCmd
    .CommandType = CommandType.StoredProcedure
    .CommandText = "Sales.sp_Customer_UpdateMetadata"
    .Parameters.Add("@CustomerId", SqlDbType.UniqueIdentifier)
    .Parameters.Add("@" + DbSyncSession.SyncCreatePeerKey, SqlDbType.Int)
    .Parameters.Add("@" + DbSyncSession.SyncCreatePeerTimestamp, SqlDbType.BigInt)

    .Parameters.Add("@" + DbSyncSession.SyncUpdatePeerTimestamp, SqlDbType.BigInt)

    .Parameters.Add("@" + DbSyncSession.SyncRowTimestamp, SqlDbType.BigInt)
    .Parameters.Add("@" + DbSyncSession.SyncRowCount, SqlDbType.Int).Direction = ParameterDirection.Output
End With
