Precision is the number of digits in a number. Scale is the number of digits to the right of the decimal point in a number. For example, the number123.45has a precision of5and a scale of2. In SQL Server, the default maximum precision ofnumericanddecimaldata types is 38. ...

Many people are confused about SQL Server's precision and scale. This is unfortunate because choosing the correct values for precision and scale is critically important when you perform math operations using the decimal/numeric data type. The point of this blog is to explain how SQL Server determ...
SQLServer中PRECISION和LENGTH,还有SCALE的区别 总是搞不清楚,每次自己测试之后又忘记。故今天记录在案 CST_NAME输入大于5个字符或两个汉字加一个字符,报错 String or binary data would be truncated. The statement has been terminated. length varchar和nvarchar类型中,注意中文和字符所占位数的区别 注意CST_REGISTRA...
precision意为“精密度、精确”，表示该字段的有效数字位数了。scale意为“刻度、数值范围”，表示该字段的小数位数。举个简单的例子 123.45：precision = 5 ，scale = 2 precision 数据长度 scale 小数长度 举

—— scale可以是零或者正数,规定了小数点后有几位。 numeric(m)表示了scale是0,与numeric(m,0)的含义相同。 而numeric表示precision和scale没有指定,可以存储任意精度和标度的数值。 postgres=# create table tb_int(id1 numeric(3),id2 numeric(3,0),id3 numeric(3,2),id4 numeric); ...

有关SQL Server 数据类型的详细信息,请参阅数据类型。 <COLUMN>元素的属性 本部分介绍<COLUMN>元素的属性,这些属性在以下架构语法中汇总: XML <COLUMNSOURCE="fieldID"NAME="columnName"xsi:type="columnType"[LENGTH="n"] [PRECISION="n"] [SCALE="value"] [NULLABLE={"YES" | "NO" } ] /> ...
- Scale: int - Precision: int + InsertData() } 结论 Money类型在SQL Server中用于存储金钱值,具有固定的标度和精度。虽然Money类型的标度和精度无法更改,但在实际使用中,我们可以通过四舍五入的方式来控制小数点后的精度。通过本文的介绍,希望读者对SQL Server中Money类型的标度和精度有更深入的了解。
