+
+返回 *date1* 和 *date2* 之间的月份数。
+
+## 语法
+
+```sql
+MONTHS_BETWEEN( <date1>, <date2> )
+```
+
+## 参数
+
+*date1* 和 *date2* 可以是 DATE 类型、TIMESTAMP 类型，或两者的混合。
+
+## 返回类型
+
+该函数根据以下规则返回一个 FLOAT 值：
+
+- 如果 *date1* 早于 *date2*，函数返回一个负值；否则，返回一个正值。
+
+    ```sql title='示例:'
+    SELECT
+        MONTHS_BETWEEN('2024-03-15'::DATE,
+                    '2024-02-15'::DATE),
+        MONTHS_BETWEEN('2024-02-15'::DATE,
+                    '2024-03-15'::DATE);
+
+    -[ RECORD 1 ]-----------------------------------
+    months_between('2024-03-15'::date, '2024-02-15'::date): 1
+    months_between('2024-02-15'::date, '2024-03-15'::date): -1
+    ```
+
+- 如果 *date1* 和 *date2* 落在各自月份的同一天，或者两者都是各自月份的最后一天，结果是整数。否则，函数根据一个31天的月份计算结果的小数部分。
+
+    ```sql title='示例:'
+    SELECT
+        MONTHS_BETWEEN('2024-02-29'::DATE,
+                    '2024-01-29'::DATE),
+        MONTHS_BETWEEN('2024-02-29'::DATE,
+                    '2024-01-31'::DATE);
+
+    -[ RECORD 1 ]-----------------------------------
+    months_between('2024-02-29'::date, '2024-01-29'::date): 1
+    months_between('2024-02-29'::date, '2024-01-31'::date): 1
+
+    SELECT
+        MONTHS_BETWEEN('2024-08-05'::DATE,
+                    '2024-01-01'::DATE);
+
+    -[ RECORD 1 ]-----------------------------------
+    months_between('2024-08-05'::date, '2024-01-01'::date): 7.129032258064516
+    ```
+
+- 如果 *date1* 和 *date2* 是相同的日期，函数忽略任何时间部分并返回0。
+
+    ```sql title='示例:'
+    SELECT
+        MONTHS_BETWEEN('2024-08-05'::DATE,
+                    '2024-08-05'::DATE),
+        MONTHS_BETWEEN('2024-08-05 02:00:00'::TIMESTAMP,
+                    '2024-08-05 01:00:00'::TIMESTAMP);
+
+    -[ RECORD 1 ]-----------------------------------
+                                months_between('2024-08-05'::date, '2024-08-05'::date): 0
