将 PascalCase 字符串转换为“友好名称"在 TSQL 中
我有一个表,其中一列的值来自枚举.我需要创建一个 TSQL 函数,以便在检索时将这些值转换为友好名称".
I have a table with a column whose values come from an Enumeration. I need to create a TSQL function to convert these values to "Friendly Names" upon retrieval.
示例:
'DateOfBirth' --> 'Date Of Birth'
'PrincipalStreetAddress' --> 'Principal Street Address'
我需要一个直接的 TSQL UDF 解决方案.我没有安装扩展存储过程或 CLR 代码的选项.
I need a straight TSQL UDF solution. I don't have the option of installing Extended Store Procedures or CLR code.

/*
Try this. It's a first hack - still has problem of adding extra space
at start if first char is in upper case.
*/
create function udf_FriendlyName(@PascalName varchar(max))
returns varchar(max)
as
begin
declare @char char(1)
set @char = 'A'
-- Loop through the letters A - Z, replace them with a space and the letter
while ascii(@char) <= ascii('Z')
begin
set @PascalName = replace(@PascalName, @char collate Latin1_General_CS_AS, ' ' + @char)
set @char = char(ascii(@char) + 1)
end
return LTRIM(@PascalName) --remove extra space at the beginning
end
