Hi @spark123 ,

Thanks for reaching out to the Microsoft Fabric Community Forum.

Based on the error screenshot you provided

It looks like Delta tables in Microsoft OneLake/Fabric do not support explicit partition management using SHOW PARTITIONS. Unlike traditional Hive-style partitioned tables, Delta Lake manages partitions automatically, which means direct partition manipulation commands aren’t available.

Workarounds

Using DeltaLake Python API

from delta.tables import DeltaTable

dt = DeltaTable.forName(spark, "your_table")

dt.detail().show()

DESCRIBE DETAIL your_table;

Use SQL to get distinct partition values:

SELECT DISTINCT partition_column_name FROM LakehouseCatalogName.schemaName.tableName;

SELECT DISTINCT partition_column FROM your_table;
