To inquire about table column names, you can use one of the following two methods in the Oracle database: 1. Use the DESCRIBE command.

  DESC 表名

For example, to retrieve all field names in a table named “employees,” you can execute the following command:

  DESC employees

This will return the structure of the table, including field names, data types, and constraints. 2. Query the metadata table using the SELECT statement.

  SELECT COLUMN_NAME FROM ALL_TAB_COLUMNS WHERE TABLE_NAME = '表名'

To retrieve the names of all fields in a table named “employees”, you can execute the following command:

  SELECT COLUMN_NAME FROM ALL_TAB_COLUMNS WHERE TABLE_NAME = 'employees'

This will return the names of all fields in the table. Please note that depending on your access permissions and database settings, you may not be able to query the field names of certain tables.
