什么相当于Oracle数据库的Number(4)到
MySQL数据类型?
解决方法
在Oracle中:
The NUMBER datatype stores fixed and
floating-point numbers. Numbers of
virtually any magnitude can be stored
and are guaranteed portable among
different systems operating Oracle,up
to 38 digits of precision.
数字(9)的7,456,123.89存储为7456124.

在MySQL中:
您可以使用以下任何数据类型,因为您不想存储值的小数部分…
SMALLINT( ) -32768 to 32767 normal 0 to 65535 UNSIGNED. MEDIUMINT( ) -8388608 to 8388607 normal 0 to 16777215 UNSIGNED. INT( ) -2147483648 to 2147483647 normal 0 to 4294967295 UNSIGNED. BIGINT( ) -9223372036854775808 to 9223372036854775807 normal 0 to 18446744073709551615 UNSIGNED.
