Oracle修改表數據的方法主要有以下幾種：
UPDATE table_name
SET column1 = value1, column2 = value2
WHERE condition;
MERGE INTO target_table USING source_table
ON (condition)
WHEN MATCHED THEN
UPDATE SET column1 = value1, column2 = value2
WHEN NOT MATCHED THEN
INSERT (column1, column2) VALUES (value1, value2);
DECLARE
v_value1 table_name.column1%TYPE;
BEGIN
SELECT column1 INTO v_value1 FROM table_name WHERE condition;
-- 修改數據
UPDATE table_name SET column1 = v_value1 WHERE condition;
COMMIT;
END;
這些是常用的Oracle修改表數據的方法，可以根據具體情況選擇合適的方法來完成數據修改操作。
