Importing CSV data into PL\/SQL can be achieved through the following steps:<\/p>\n

    \n
  1. Create an external table that matches the structure of a CSV file. External tables allow access and querying of external data files as if they were tables.<\/li>\n<\/ol>\n
    CREATE<\/span> TABLE<\/span> ext_table\r\n(\r\n  column1 datatype,\r\n  column2 datatype,\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> comma\r\n    ...\r\n  )\r\n  LOCATION ('file_name.csv'<\/span>)\r\n)\r\nREJECT LIMIT UNLIMITED;\r\n<\/code><\/pre>\n
      \n
    1. Create a data loading script that imports data from an external table into the target table using the INSERT INTO statement.<\/li>\n<\/ol>\n
      INSERT<\/span> INTO<\/span> target_table\r\nSELECT<\/span> *<\/span>\r\nFROM<\/span> ext_table;\r\n<\/code><\/pre>\n
        \n
      1. Run the data loading script to import the data from the CSV file into the target table in the database.<\/li>\n<\/ol>\n
        Notice:<\/p>\n
          \n
        1. Make sure the structure of the external table matches the structure of the CSV file, otherwise the data import may fail.<\/li>\n
        2. When creating an external table, it is necessary to specify parameters such as the delimiter and field format of the CSV file.<\/li>\n
        3. Data in external tables can be queried through SQL statements, but cannot be directly updated or deleted in the external tables.<\/li>\n
        4. When importing data, it is important to ensure that the paths, file names, and target table names of the CSV file are correct.<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
