There are two methods to check table comments.<\/p>\n

    \n
  1. Use the DESCRIBE TABLE statement to query information about the table and look for the table comments in the results. For example:<\/li>\n
  2. Provide a description of the table named table_name in the specified database.<\/li>\n
  3. This will return information about the columns in the table, including comments.<\/li>\n
  4. Retrieve detailed information about the table, including table comments, using the “SHOW TABLE EXTENDED” statement. For example:<\/li>\n
  5. Display the detailed information of the table named ‘table_name’ in the specified database.<\/li>\n
  6. This will provide detailed information about the table, including comments.<\/li>\n<\/ol>\n

    Please make sure to use the correct database and table names in your query. If using Hive or Impala, you may also need to add the appropriate prefix based on the specific situation (for example, use “USE database_name;” to switch to the correct database).<\/p>\n","protected":false},"excerpt":{"rendered":"
