如何使用用户定义的函数?

[英]How can I use user defined functions?


I have a table Users, so some rows specially in field Full Name are in different upper/lower case, so i found this function:

我有一个表用户,所以特别是字段全名的一些行是大小写不同的,所以我找到了这个函数:

CREATE function properCase(@texto varchar(8000)) returns varchar(8000) as   
begin   
    --declare @texto = 'hola'  
    set @texto = lower(@texto)   

    declare @i int   
    set @i = ascii('a')   

    while @i <= ascii('z')   
    begin   

        set @texto = replace(@texto, ' ' + char(@i), ' ' + char(@i-32))   
        set @i = @i + 1   
    end   

    set @texto = char(ascii(left(@texto, 1))-32) + right(@texto, len(@texto)-1)   

    return @texto   
end  

How can I use this function to update or select the "fullname" field from my user table?

如何使用此功能更新或从我的用户表中选择“fullname”字段?

2 个解决方案

#1


SELECT dbo.properCase(fullname) FROM [user]

and

UPDATE [user] SET fullname = dbo.properCase(fullname)

#2


SELECT dbo.properCase(FullName) FROM [User]

and:

UPDATE [User] SET FullName = dbo.properCase(FullName)
