Oracle多表查詢的方法有以下幾種:
SELECT * FROM table1
JOIN table2 ON table1.column = table2.column;
SELECT * FROM table1
WHERE column IN (SELECT column FROM table2);
SELECT column FROM table1
UNION
SELECT column FROM table2;
WITH temp_table AS (
SELECT column FROM table1
)
SELECT * FROM temp_table
JOIN table2 ON temp_table.column = table2.column;
這些方法可以根據具體的需求和數據結構選擇最合適的方式進行多表查詢。
