Sql 创建视图时可以有这样的列

带前导美元符号（

FM$99999.99

）可用于以下情况：

CREATE VIEW sales_summary_v AS
COLUMN Max HEADING Max FORMAT $99,999.99;
COLUMN Min HEADING Min FORMAT $99,999.99;
SELECT MAX(Value) as Max, MIN(value) as Min
FROM Table_name;

---

嗯？我猜这是甲骨文？您正在将sqlplus语句与SQL语句混合使用。

CREATE VIEW sales_summary_v AS
SELECT to_char(MAX(Value),'FM$99,999.99') as Max, 
       to_char(MIN(Value),'FM$99,999.99') as Min
  FROM Table_name;
