You are using the SHOW DATABASES command and it returns an unexpected column name.


The column name returned by the SHOW DATABASES command changed in Databricks Runtime 7.0.

  • Databricks Runtime 6.4 Extended Support and below: SHOW DATABASES returns namespace as the column name.
  • Databricks Runtime 7.0 and above: SHOW DATABASES returns databaseName as the column name.


You can enable legacy column naming by setting the property spark.sql.legacy.keepCommandOutputSchema to false in the cluster’s Spark config (AWS | Azure | GCP).
