在MySQL中進行跨表查詢和連接操作通常使用JOIN語句來實現。以下是一些常用的跨表查詢和連接操作方式:
SELECT * FROM table1
INNER JOIN table2
ON table1.column_name = table2.column_name;
SELECT * FROM table1
LEFT JOIN table2
ON table1.column_name = table2.column_name;
SELECT * FROM table1
RIGHT JOIN table2
ON table1.column_name = table2.column_name;
SELECT * FROM table1
FULL JOIN table2
ON table1.column_name = table2.column_name;
SELECT * FROM table1 t1
JOIN table1 t2
ON t1.column_name = t2.column_name;
以上是一些常見的跨表查詢和連接操作方式,可以根據實際需求選擇適合的連接方式進行查詢。
