oracle 小数格式化作百分数
oracle 小数格式化为百分数
以下是从JAVAEYE中找到的代码，用途是将小数 转换为百分数形式：
Select CONCAT(TO_CHAR('0.001'*100,'990.99'),'%') FROM DUAL;
除此之外，还找到了其余的转换，放到这里留作日后之用：
select to_char(1234567.89,'9,999,999.99') id from dual;
select to_char(1234567.89,'999,999,999.99') id from dual;
select to_char(1234567.89,'009,999,999.9900') id from dual;
select to_char(1234567.89,'9.99EEEE') id from dual;
select to_char(1234567.89,'999999.99EEEE') id from dual;
select to_char(-1234567.89,'999,999,999.99PR') id from dual;
