oracleORA-01438
ORA-01438: 值大于此列指定的允许精确度 比如定义为number(4,2),却要插入一个值200.12的话,就会出错啊,原因是number(p,s)的问题。 number(p,s),其中p表示该number的总长度,s为小数位。 如果s为负数,则会取相应位数的取整。 例如,如果number(4,-3)
ORA-01438: 值大于此列指定的允许精确度
比如定义为number(4,2),却要插入一个值200.12的话,就会出错啊,原因是number(p,s)的问题。
number(p,s),其中p表示该number的总长度,,s为小数位。
如果s为负数,则会取相应位数的取整。
例如,如果number(4,-3),则数字1234的存储值为1000;如果number(4,-2),则数字1234的存储值为1200。
在对数据库表中的字段设定类型时,要注意:
NUMBER(10,6) Double 带有小数
NUMBER(4) Long
