Oracle修改表数据的方法主要有以下几种:
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;
-- 修改数据
UPDATE table_name SET column1 = v_value1 WHERE condition;
COMMIT;
END;
这些是常用的Oracle修改表数据的方法,可以根据具体情况选择合适的方法来完成数据修改操作。
