要修改select查詢結果,你需要使用update語句。下面是一些常見的方法:
UPDATE table1
JOIN table2 ON table1.id = table2.id
SET table1.column = table2.column
WHERE condition;
UPDATE table1
SET column = (
SELECT column
FROM table2
WHERE condition
)
WHERE condition;
CREATE TEMPORARY TABLE temp_table
SELECT column
FROM table
WHERE condition;
UPDATE table
SET column = (
SELECT column
FROM temp_table
)
WHERE condition;
DROP TEMPORARY TABLE temp_table;
請根據你的具體需求選擇適合的方法來修改select查詢結果。
