1>.NUMBER类型细讲: Oracle number datatype 语法:NUMBER[(precision [, scale])] 简称:precision –> p scale –> s NUMBER(p, s) 范围: 1 <= p <=38, -84 <= s <= 127 保存数据范围:-1.0e-130 <= number value < 1.0e+126 保存在机器内部
0)Oracle data type to theboolEDM type. For example,Number(1,0), which is mapped toInt16by default, can be custom mapped to the .NETBoolor .NETBytetype. This example mapsNumber(3,0)tobyte, and sets the maximum precisions for theInt16, Int32,andInt64data types to 4, 9, and 18 ...
Oracle number datatype 语法:NUMBER[(precision [, scale])] 简称:precision --> p scale --> s NUMBER(p, s) 范围: 1 <= p <=38, -84 <= s <= 127 保存数据范围:-1.0e-130 <= number value < 1.0e+126 保存在机器内部的范围: 1 ~ 22 bytes 有效为:从左边第一个不为0的数算起的位数。

Internal representation of the NUMBER datatype As with other datatypes, stored numbers are preceded by a length byte which stores the size of the datum in bytes, or 0xFF for NULLs. The actual data bytes for non-null numbers represent the value in scientific notation. For example, the number...
