Description
I have Iceberg table:
CREATE TABLE table_with_iceberg_engine_1ff2d5bc_9337_11f0_806a_e0c26496f172
ENGINE=Iceberg('http://minio:9000/warehouse/data', '***', '***')
I comment column:
ALTER TABLE table_with_iceberg_engine_1ff2d5bc_9337_11f0_806a_e0c26496f172 COMMENT COLUMN long_col 'comment_1ff94dae_9337_11f0_bd42_e0c26496f172'
I use describe and expect to see my comment there:
DESCRIBE TABLE table_with_iceberg_engine_1ff2d5bc_9337_11f0_806a_e0c26496f172
