在之前,我遇到了一个问题,总结整理在“ORACLE NUMBER类型Scale为0引发的问题”这篇博客当中,当时武断的判断“如果不指定p和s,NUMBER类型,它的默认精度值为38,默认的scale值为0”,因为当时参考了官方文档https://docs.oracle.com/cd/B28359_01/server.111/b28318/datatype.htm#

NUMBER数据类型的定义格式是:NUMBER(p,s)。本文对定义中的p(precision)和s(scale)做一个解释和总结。 1.官方文档中有关NUMBER数据类型的描述 p is the precision, or the total number of significant decimal digits, where the most significant digit is the left-most nonzero digit, and the least signifi...
NUMBER数据类型 NUMBER ( precision, scale)a) precision表示数字中的有效位;如果没有指定precision的话,Oracle将使用38作为精度。 b) 如果scale大于零,表示数字精确到小数点右边的位数;scale默认设置为0;如果scale小于零,Oracle将把该数字取舍到小数点左边的指定位数。

Number13 An OracleNUMBERdata type that contains variable-length numeric data with a maximum precision and scale of 38. This maps toDecimal. To bind an OracleNUMBERthat exceeds whatDecimal.MaxValuecan contain, either use anOracleNumberdata type, or use aStringparameter and the Oracle TO_NUMBER ...
The NUMBER datatype can also accept two qualifiers, as in: column NUMBER( precision, scale ) The precision of the datatype is the total number of significant digits in the number. You can designate a precision for a number as any number of digits up to 38. If no value is declared for...
