- Currently only classification of database columns is supported.
A. Listing all classified columns and their corresponding classification
The following example returns a table that lists the table name, column name, label, label ID, information type, information type ID, rank, and rank description for each classified column in the database.
Label is a keyword for Azure Synapse Analytics.
SELECT SCHEMA_NAME(sys.all_objects.schema_id) as SchemaName, sys.all_objects.name AS [TableName], sys.all_columns.name As [ColumnName], [Label], [Label_ID], [Information_Type], [Information_Type_ID], [Rank], [Rank_Desc] FROM sys.sensitivity_classifications left join sys.all_objects on sys.sensitivity_classifications.major_id = sys.all_objects.object_id left join sys.all_columns on sys.sensitivity_classifications.major_id = sys.all_columns.object_id and sys.sensitivity_classifications.minor_id = sys.all_columns.column_id
