Just as with BULK INSERT, you have to define an external data source, including credentials necessary for authorization purposes. OPENROWSET(BULK.): offers more advanced capabilities (comparing with BULK INSERT), which allow for parsing content of a data source (such as a blob residing in an Azure Storage account) and executing T-SQL statements on returned rows before initiating the load (when implementing the BULK INSERT-based approach, you could use for this purpose a temporary table).The credential is part of the external data source definition (which, in this case, would include also the URI representing the location of the Azure Storage blob container). When importing data from Azure Storage, such credential would include the target storage account key or a Shared Access Signature token. Note that in order to provide security context in such scenario (assuming that the blob is not accessible anonymously), you need to create a new or use an existing database master key (for encrypting secrets necessary to authorize access to the storage account) and a database scoped credential (for authenticating Azure SQL Database to the external data source). You can, for example, import content of a blob residing in an Azure Storage account (constituting an external data source). BULK INSERT: loads raw data into a target table from a designated flat file.
Transact-SQL statements: You have the option of invoking import directly from the target Azure SQL Database instance by running either of the following:.The most straightforward methods that you can use in order to import data into tables hosted by an instance of Azure SQL Database include: In this article, you will get an overview of these techniques and learn about the cloud-specific aspects of importing. When importing data into Azure SQL Database, you can leverage a number of traditional SQL Server data import techniques. Data imports represent some of the more commonly performed database management tasks.
