If the number does not have a decimal position (like an integer number), then SQL Server will add implicitly .00 to the number. For Example, 123 will become 123.00 Maximum Limit The precision and scale determine

标准SQL要求DECIMAL(5,2)能够存储五位数和两位小数的任何值,因此可以存储在薪水列中的值范围为-999.99至999.99。 在标准SQL中,语法DECIMAL(M)等效于DECIMAL(M,0)。类似地,语法DECIMAL等效于DECIMAL(M,0),M的默认值为10。 如果刻度为0,则DECIMAL值不包含小数点或小数部分。 DECIMAL的最大位数为65。 浮点数值(...

有关SqlDbType.Decimal 大家好,又见面了,我是你们的朋友全栈君。 今天在开发过程中遇到SqlDbType.Decimal类型的参数,返回值却是没有小数位的整数值,郁闷坏了。查了半天资料,原来需要指定小数位。具体书写如下: cmd.Parameters.Add(“@Percent”, SqlDbType.Decimal).Direction = ParameterDirection.Output; cmd....
SQL Decimal provides greater accuracy for fractional decimal values, which is crucial for business transactions. Feature details In Power Apps, floating point values are the default data type for internal values. This means that any data flowing into Power Apps is internally represented as a...
AddParamToSQLCmd(sqlCmd, "@CountOfValue", SqlDbType.Int, 4, ParameterDirection.Input, CntOfValue); SqlParameter outputA2 = sqlCmd.Parameters.Add("@A2", SqlDbType.Float);//如果写成SqlDbType.Decimal ,则返回的是整数,不是小数 outputA2.Direction = ParameterDirection.Output; ...

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. ...
