SELECT

</select>



TO_CHAR 是把日期或数字转换为字符串 

TO_CHAR(number, '格式')

TO_CHAR(date,’格式’)



例如：

TO_CHAR(salary,’$99,999.99’) 

TO_CHAR(newdate,’yyyy-mm-dd’) 



指定字符串的长度可以使用lpad或者rpad或者substring：



lpad(字段名,填充长度,填充的字符) 左填充

rpad(字段名,填充长度,填充的字符) 右填充

substr( string, start_position, [ length ] )取得字符串中指定起始位置和长度的字符串
