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，但您需要从 中指定列名Table_1，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
