View asset details for listed Dataphin tables and external system tables, including properties, data lineage, data preview, and quality profiles.
Prerequisites
You have purchased the Asset Operations value-added service, and the Asset Operations module is enabled for the current tenant.
Limitations
-
When the data source type is PolarDB-X (formerly DRDS), SAP HANA, IBM DB2, or OceanBase (in MySQL or Oracle tenant mode), you cannot apply for consumption permissions for data source tables or their custom metrics.
-
For data source tables, configure a data source code to use data preview. Data source management.
-
For supported data sources for data preview and data profiling, see Operations supported for different types of collection sources.
Table asset details
-
In the top navigation bar of the Dataphin homepage, choose Assets > Asset Catalog.

Data Preview: If you have query permissions for the table, use data preview. Results include only fields to which you have SELECT permissions (including field-level and row-level). Up to 50 records can be previewed. To learn how to apply for query permissions (if asset consumption is enabled, see Apply for consumption permissions), see Apply for, renew, and revoke table permissions and Apply for consumption permissions. For supported data sources, see Supported data sources and ranges for data profiling.
NoteFor some compute engines or data sources, if the collected table is a lake table that uses the Spark SQL query engine by default, you must enable Spark configuration for the table's compute engine or data source before you can query its data.
