You can create an external table in Oracle by following these steps:<\/p>\n

    \n
  1. Firstly, it is important to ensure that the database user has the permission to create tables, as well as access external files.<\/li>\n
  2. Create an external table using the CREATE TABLE statement, with the following syntax:<\/li>\n<\/ol>\n
    CREATE<\/span> TABLE<\/span> external_table_name\r\n(\r\n  column1 data_type,\r\n  column2 data_type,\r\n  ...\r\n)\r\nORGANIZATION EXTERNAL<\/span>\r\n(\r\n  TYPE ORACLE_LOADER\r\n  DEFAULT<\/span> DIRECTORY directory_name\r\n  ACCESS PARAMETERS\r\n  (\r\n    RECORDS DELIMITED BY<\/span> NEWLINE\r\n    FIELDS TERMINATED BY<\/span> ','<\/span>\r\n    LOCATION ('external_file_name'<\/span>)\r\n  )\r\n)\r\nREJECT LIMIT UNLIMITED;\r\n<\/code><\/pre>\n
    In this case, external_table_name is the name of the external table created, column1 and column2 are the column names and data types of the external table, directory_name is the name of the directory where the external files are located, and external_file_name is the name of the external file.<\/p>\n
      \n
    1. In the ACCESS PARAMETERS clause, you can configure parameters such as the format of external files and the delimiter of data.<\/li>\n
    2. When creating an external table, it is important to ensure that the path and format of the external files are consistent with what is specified in the ACCESS PARAMETERS.<\/li>\n
    3. After creating an external table, you can use a SELECT statement to query the data in the external table, which is dynamically loaded from external files.<\/li>\n
    4. If you need to delete an external table, you can use the DROP TABLE statement to delete the external table.<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
