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...
SQLCopy SELECTCAST(0.0000009000ASDECIMAL(30,20)) *CAST(1.0000000000ASDECIMAL(30,20)) [decimal(38,17)]; In this case precision is61, and scale is40. The integral part(precision-scale = 21)is less than 32, so this case is the first case in the multiplication rules, and scale is calcula...
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 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 number 123.45 has a precision of 5 and a scale of 2. In SQL Server, the default maximum precision of numeric and decimal data types is 38....

I suspect the issue might be caused by the driver code incorrectly assuming that the precision and scale values of BigDecimal mirror those of the decimal data type in SQL Server, namely the code foundhere. Let me know if any additional details would be helpful. ...
属性Precision由 为SqlDbType的参数Decimal使用。 无需为Precision输入参数指定 和Scale属性的值,因为它们可以从参数值推断。Precision和Scale对于输出参数和需要指定参数的完整元数据而不指示值(例如指定具有特定精度和小数位数的 null 值)的方案,和 是必需的。
屬性Precision 是由 具有 SqlDbType 的Decimal參數使用。 您不需要為輸入參數指定 和 Scale 屬性的值Precision,因為它們可以從參數值推斷。 Precision 和Scale 是輸出參數的必要專案,以及您需要指定參數的完整元數據而不指出值的情況,例如指定具有特定有效位數和小數字數的 Null 值。 備註 不支援使用這個屬性來強...
