18) DECIMAL specifies the data type exact numeric, with the decimal scale specified by the <scale> and the implementation-defined decimal precision equal to or greater than the value of the specified <precision>. Conclusion The SQL DECIMAL data type is part of the SQL standard and is implement...
bPrecision Byte 可以用來表示新 Value 結構之 SqlDecimal 屬性的最大位數。 bScale Byte Value 屬性要對新 SqlDecimal 結構解析的小數位數。 fPositive Boolean 布林值,指出新的 SqlDecimal 結構是否表示正數或負數。 data1 Int32 32 位元不帶正負號的整數 (Unsigned Integer),將與 data2、data3 和 data...
Examples The following expression returns result0.00000090000000000without rounding, because the result can fit intodecimal(38, 17): SQLCopy SELECTCAST(0.0000009000ASDECIMAL(30,20)) *CAST(1.0000000000ASDECIMAL(30,20)) [decimal(38,17)]; In this case precision is61, and scale is40. ...
In Transact-SQL statements, a constant with a decimal point is automatically converted into a numeric data value, using the minimum precision and scale necessary. For example, the constant 12.345 is converted into a numeric value with a precision of 5 and a scale of 3....

The IDENTITY property can be assigned to tinyint, smallint, int, bigint, decimal(p,0), or numeric(p,0) columns. Only one identity column can be created per table. Bound defaults and DEFAULT constraints can't be used with an identity column. You must specify both the seed and increment...

The scale must always be less than or equal to the precision. Defining SQL Decimal Data type Let’s work with a very popular mathematical constant –π, aka, Pi that has a value equal to 3.14159 (22/7 in a fraction). Copy and paste the below query in a new query window and ...
