1. 解释什么是 PostgreSQL 的 numeric 类型溢出 在PostgreSQL 中,numeric 类型用于存储任意精度的数值。然而,即使 numeric 类型支持高精度,它仍然有一个限制,即数值的总位数(精度)和小数位数(标度)是有限制的。当尝试将超出这些限制的值插入到 numeric 类型的列中时,就会发生 numeric field overflow 错误。这意味着...
1、以insert一个numeric类型值为例 表一个字段为numeric(10,2)类型,表示存储10位数字,精确到小数点后两位。当插入的值超过10位时就会报错:numeric field overflow 首先观察报错的位置: 由ereport输出打印日志。从函数ereport_domain函数的调用逻辑,如下图所示,可以看到通过siglongjmp函数进行跳转。 2、PG_TRY/PG_CA...
不过,对numeric 类型进行算术运算比整数类型和浮点类型要慢很多。 numeric类型有两个术语,分别是标度和精度。numeric类型的标度(scale)是到小数点右边所有小数位的个数, numeric 的精度(precision)是所有数字位的个数,例如,23.5141 的精度是6而标度为4。可以认为整数的标度是零。 numeric 类型的最大精度和最大标度...

This is used when an overflow or underflow occurs on a computation and when a control MI instruction has a receiver that is a binary field. The receiver contains the left-truncated result.
