报错：There is no supertype for types Int32, String because some of them are String/FixedString and som

① UNION ALL语法用于将两个或多个SELECT语句的结果集合并为一个结果集。它的语法如下：

SELECT column1, column2, ... FROM table1
UNION ALL
SELECT column1, column2, ... FROM table2;

其中，column1, column2, ...是要查询的列名，table1和table2是要查询的表名。注意，两个SELECT语句的列数必须相同，且对应的列的数据类型也必须相同。

UNION ALL与UNION的区别在于，UNION会去重，而UNION ALL不会去重。因此，如果需要合并两个结果集并保留重复的行，可以使用UNION ALL。

② CAST语法用于将一个值转换为指定的数据类型。用于创建一些空的列，这些空的列在UNION ALL操作中被用于匹配两个SELECT语句的列，以便在结果集中创建一个完整的表格。

这里之所以会报错是因为：type字段的类型在ioa_log表中为字符串类型，在icmp_log表中为int64类型。可以将ioa_log表中的 type 字段重命名为IoaType，则SQL就会变为：
