The following are number examples for the to_char function. to_char(1210.73, '9999.9') would return '1210.7' to_char(1210.73, '9,999.99') would return '1,210.73' to_char(1210.73, '$9,999.00') would return '$1,210.73' to_char(21, '000099') would retur

近期在使用oracle to_char函数处理浮点数时发现有坑,这里做个小结: 网上可以找到关于to_char中使用fm9990.0099中的相关解释: 0表示:如果参数(double或者float类型)存在数字就显示数字,不存在数字就显示0 9表示:如果参数(double或者float类型)存在数字就显示数字,不存在数字就显示空格 FM表示:将9带来的空格删除 下面通过具体代码进行相关验证 --SQL示例代码: With Tmp As (Select 2312320.012 n From du
