MySQL Decimal Default Value 方案 在现代数据库设计中,DECIMAL数据类型常用于存储精度要求较高的数值,比如财务数据。这篇文章将讨论如何在 MySQL 中为DECIMAL数据类型设置默认值,并提供最佳实践的方案。 一、项目背景 在很多业务应用中,尤其是涉及财务计算的系统中,确保数值的精度和有效性至关重要。本项目旨在设计一个...
For FLOAT, the SQL standard permits an optional specification of the precision (but not the range of the exponent) in bits following the keywordFLOAT in parentheses. MySQL also supports this optional precision specification, but the precision value is used only to determine storage size. A precisi...
