To invoke a cursor in a PL\/SQL stored procedure, you can follow these steps:<\/p>\n

    \n
  1. Declare a cursor variable and associate it with a cursor in the stored procedure. For example:<\/li>\n<\/ol>\n
    DECLARE<\/span>\r\n  CURSOR<\/span> cursor_name IS<\/span>\r\n    SELECT<\/span> column1, column2\r\n    FROM<\/span> table_name;\r\nBEGIN<\/span>\r\n  -- \u5b58\u50a8\u8fc7\u7a0b\u7684\u5176\u4ed6\u903b\u8f91<\/span>\r\nEND<\/span>;\r\n<\/code><\/pre>\n
      \n
    1. Unlocked<\/li>\n<\/ol>\n
      OPEN<\/span> cursor_name;\r\n<\/code><\/pre>\n
        \n
      1. Bring<\/li>\n<\/ol>\n
        FETCH<\/span> cursor_name INTO<\/span> variable1, variable2;\r\n<\/code><\/pre>\n
          \n
        1. Handle the data in the cursor. After getting the data in the cursor, you can process it as needed.<\/li>\n
        2. Close the cursor. Use the CLOSE statement to close the cursor, for example:<\/li>\n<\/ol>\n
          CLOSE<\/span> cursor_name;\r\n<\/code><\/pre>\n
          The complete example code is as follows:<\/p>\n
          DECLARE<\/span>\r\n  CURSOR<\/span> cursor_name IS<\/span>\r\n    SELECT<\/span> column1, column2\r\n    FROM<\/span> table_name;\r\n  variable1 table_name.column1%<\/span>TYPE;\r\n  variable2 table_name.column2%<\/span>TYPE;\r\nBEGIN<\/span>\r\n  OPEN<\/span> cursor_name;\r\n  \r\n  LOOP\r\n    FETCH<\/span> cursor_name INTO<\/span> variable1, variable2;\r\n    EXIT WHEN<\/span> cursor_name%<\/span>NOTFOUND;\r\n    \r\n    -- \u5bf9\u6e38\u6807\u4e2d\u7684\u6570\u636e\u8fdb\u884c\u5904\u7406<\/span>\r\n    -- \u5728\u6b64\u5904\u53ef\u4ee5\u4f7f\u7528\u53d8\u91cfvariable1\u548cvariable2\u6765\u8bbf\u95ee\u6e38\u6807\u4e2d\u7684\u6570\u636e<\/span>\r\n    \r\n    -- \u5904\u7406\u5b8c\u6210\u540e\uff0c\u7ee7\u7eed\u5faa\u73af\u83b7\u53d6\u4e0b\u4e00\u884c\u6570\u636e<\/span>\r\n  END<\/span> LOOP;\r\n  \r\n  CLOSE<\/span> cursor_name;\r\n  \r\n  -- \u5b58\u50a8\u8fc7\u7a0b\u7684\u5176\u4ed6\u903b\u8f91<\/span>\r\nEND<\/span>;\r\n<\/code><\/pre>\n
