Paramètres

• packageFileName
  Type : System.String
  Path of the target package file.

• databaseName
  Type : System.String
  Name of the source database.

• modelStorageType
  Type : Microsoft.SqlServer.Dac.DacSchemaModelStorageType
  Specifies the type of backing storage for a schema model.

• tables
  Type : System.Collections.Generic.IEnumerable<Tuple<String, String>>
  Optional enumerable used to retrieve enumerator over set of tables for which data should be exported. For each Tuple in the enumeration the first item specifies the schema of the table, and the second specifies the base identifier of the table. If the value for this parameter is a null reference, data for all tables will be exported.

• cancellationToken
  Type : System.Nullable<CancellationToken>
  Optional CancellationToken that can be used to indicate that the operation should be cancelled. Use of this object does not guarantee that the operation will be cancelled.
