如果不理解基本的数据类型和四舍五入函数,那么你就可能误解四舍五入。由 于数据类型的差异(比如integer,float, decimal等等),四舍五入后的值可能 会不同。另外,由于在计算中使用的SQL Server舍入函数(ROUND(),CEILING(), FLOOR())的差异,得到的结果值也可能会不同。因此,找到用户对四舍五入的要 求接着把...
operation(optional): This parameter in SQL Server allows you to specify either 0 or omit the value, the input is rounded. If you specify 1, the value is truncated. This function can be used with both dates and numbers. What kind of input does it need? Get All Of My SQL Cheat Sheets...

为什么会有这种情况,这是因为SQL语句里面调用用户定义标量函数(UDF Scalar Function),都是逐行调用用户定义函数,这样需要为每行去提取用户定义函数的定义,然后去执行这些定义,从而导致了性能问题;更深层次的原因是因为函数采用了过程式的处理方法,而SQL Server查询数据则是基于数据集合的,这样在采用过程式的逐行处理时,S...
SQL SERVER中的用户定义函数(User Defined Functions 简称UDF)分为标量函数(Scalar-Valued Function)和表值函数(Table-Valued Function)。其中表值函数又分为Inline table-valued functions和Multistatement table-valued functions。 用户定义函数(UDF)在 SQL Server 中发挥重要的作用。用户定义函数可以用于执行复杂的逻辑...

Rounding issue - expected or bug? Hello, we use SQL Server 2019 and we got some unexpected rounding issues. See example: It is only example with numbers, in our situation there were sub selects with data types: 0.4399 = decimal(20,4) 33.00 = decimal(20,2) 1 = smallint. My question...
If the view is a partitioned view, the view is updatable, subject to certain restrictions. When it is needed, the Database Engine distinguishes local partitioned views as the views in which all participating tables and the view are on the same instance of SQL Server, and distributed partition...
