[英]Convert SQL column null values to 0
I'm new to SQL Server and I have an issue. 我是SQL Server的新手,我有一个问题。
I have this view, in which some of the columns from the formulas are allowed to be null. 我有这个观点,其中公式中的一些列被允许为null。
How could I convert these null values to 0 because if they are null, the result of the formula it will be also null. 我怎么能将这些空值转换为0,因为如果它们为null,则公式的结果也将为null。
Thanks! 谢谢!

Well, someone should put in a word for ANSI standards: 好吧,有人应该为ANSI标准说一句话:
coalesce(<column>, 0)
isNULL
is specific to databases (and even does different things in some databases). isNULL
特定于数据库(甚至在某些数据库中做不同的事情)。
You can use ISNULL (Transact-SQL) 您可以使用ISNULL(Transact-SQL)
eg 例如
(isnull(price,0)+isnull(notarycosts,0)) as Total
尝试这个:
ISNULL([nullable field], 0)
