In each of the databases in this guide (Oracle, SQL Server, MySQL, and Postgres), there is no difference. Numeric is an alias of Decimal, which means if you use Numeric you’re actually creating a Decimal data

The SQL standard requires that the precision ofNUMERIC(M,D)beexactlyMdigits. ForDECIMAL(M,D), the standard requires a precision of at leastMdigits but permits more. In MySQL,DECIMAL(M,D)andNUMERIC(M,D)are the same, and both have a precision of exactlyMdigits. ...

在SQL Server中,可以使用CAST函数将字符串转换为Decimal类型。CAST函数的语法如下: CAST(expressionASdata_type) 1. 其中,expression是要转换的表达式,data_type是目标数据类型。 例如,我们有一个字符串类型的字段price,其值为'25.50'。我们希望将其转换为Decimal类型,可以使用以下代码: ...
data_type :表示结果的所请求数据类型的文本值。 culture :可选字符串,它标识对 string_value 进行格式化的区域性。 如果未提供 culture 参数,则使用当前会话的语言。 可以使用 SET LANGUAGE 语句隐式或显式设置 此语言。 culture 接受 .NET Framework 支持的任何区域性;它不局限于 SQL Server 显式支持的语 言...
SQL 语句显示转换 decimal 数据类型示例如下: select CAST(18446744073709001000BD AS DECIMAL(38,0)); select cast(4.004E+3 AS DECIMAL(38,0)); select cast(4004 AS DECIMAL(38,0)); 3.如何更改 datax 以支持 hive 的 DECIMAL 数据类型? 如上文所述,在需要对数据进行精确表示和精确运算的场景下(比如金...
