The external data location is generated using this option and the BL_ACCOUNTNAME=, BL_FILESYSTEM=, and BL_FOLDER= LIBNAME options. These values are combined to define the URL to access an Azure Data Lake Storage Gen2 location:
https://<account-name>.<network-storage-host-name>/<file-system-name>/<file-path-folder>These values might result
in a URL similar to https://myaccount.dfs.core.windows.net/myfilesystem/myfolder.
Microsoft SQL Server: This option is used when Microsoft SQL Server loads data to Azure Synapse Analytics (SQL DW) with an Azure Data Lake Storage Gen2 storage account. For more information, see Bulk Loading to Azure Synapse Analytics.
Snowflake: This option is used to facilitate bulk loading or bulk unloading compressed Parquet files that are stored in an Azure ADLS location. For more information, see Bulk Loading and Bulk Unloading Data Files in Azure ADLS Locations.
Spark: This option is used when the Spark engine bulk loads or bulk unloads data in Databricks. For more information, see Bulk Loading and Bulk Unloading with the Spark Engine.
