in the SQL-92 standard, decimalisexactly as precise as declared, whilenumericisat least as precise as declared. In SQL Server both are exactly as precise as declared decimal 完全和声明的一样精确;numeric 至少和声明的一样精确。在 sql server 中两者使用完全和声明的一样精确。但是没有例子,很难明白。
decimal 和 numeric 在 SQL 标准中可以说是等价的的,在SQL Server 中是一样的(参考:decimal 和 numeric (Transact-SQL)),可以查看类型定义确认: SELECT * FROM sys.types WHERE name IN('DECIMAL','NUMERIC') SELECT * FROM sys.systypes WHERE name IN('DECIMAL','NUMERIC') 1. 2. 到底...

The Decimal type represents a numeric value with fixed precision and scale. This type can describe a numeric value ranging from negative 10^38 + 1 to positive 10^38 -1.This type maps to the Decimal type in SQL Server.See AlsoConceptsSingle...
Fordecimalandnumericdata types, SQL Server considers each combination of precision and scale as a different data type. For example,decimal(5,5)anddecimal(5,0)are considered different data types. In Transact-SQL statements, a constant with a decimal point is automatically converted into anumericdat...
