SQL左连接（条件之间）

Question

是否可以使用BETWEEN语句作为LEFT JOIN的条件？

SELECT Table_1.*, Table_2.*
FROM Table_1 LEFT JOIN Table_2
ON Table_1.value BETWEEN Table_2.Value_1 AND Table_2.Value_2

Answer 1

是的，确实如此，但您需要从Table_1指定一个列名，如下所示：

SELECT Table_1.*, Table_2.*
FROM Table_1 LEFT JOIN Table_2
ON Table_1.Value BETWEEN Table_2.Value_1 AND Table_2.Value_2
