我正在尝试将大写的列转换为正确的大小写，但是有一些缩写，例如某些首字母缩略词，缩写。我按照下面的代码来实现它。但看起来这将是一个持续的过程，所以，我想创建一个具有异常的表，以便清理数据，我希望能够从函数中调用例外表。如果有人能帮助我处理他们所拥有的与此类似的任何代码或任何有关如何实现它的想法，那将是很棒的。
ALTER FUNCTION [dbo].[Business_ProperCase]

RETURNS VARCHAR(8000)
AS
BEGIN
-- declare some variables
DECLARE @Reset BIT; DECLARE @Ret VARCHAR(8000); DECLARE @i INT;

-- only apply if all characters are already in uppercase
IF (UPPER(@Text)=@Text COLLATE Latin1_General_CS_AI)
BEGIN
-- add a leading and trailing space to indicate word delimiters (bol & eol)
SET @Text = ' ' + @Text + ' ';
-- cycle through each character,

创建一个带有EXCEPTION列的表（我以TITLE_CASE_EXCEPTION为例） 然后是从那里驱动数据。
conda update --all
答案 1 :(得分：0)
以下是您参考的示例：
declare @s varchar(256) = 'This is a SQL test';
declare @t table (ignore varchar(256) not null);
insert into @t (ignore) values ('SQL');
declare @pos int = 1;
declare @nextpos int;
declare @w varchar(256);
while @pos <= len(@s)
begin
set @nextpos = charindex(' ', @s + ' ', @pos);
set @w = substring(@s, @pos, @nextpos - @pos);
if not exists (select 1 from @t where ignore = @w)
set @s = stuff(
@s, @pos, @nextpos - @pos,
stuff(lower(@w), 1, 1, upper(left(@w, 1)))
);
set @pos = @nextpos + 1;
select @s;
end

要回答原始请求..设置一个表“Exceptions”，其中包含一个类型为nvarchar（100）的ConcatList，并将异常添加到此表中...然后创建一个视图，将它们连接在一起...
create table exceptions (ConcatList nvarchar(100))
create view [dbo].vExceptions
as
Select distinct
substring(
(
Select ','+ up.ConcatList AS [text()]
From exceptions up
ORDER BY up.ConcatList
For XML PATH ('')
), 2, 4000) [exceptions]
From exceptions p
以下是该问题的存储过程的略微增强版本。 （虽然这是一个公认的不优雅的解决方案）可以解释：
短划线或逗号之前或之后的异常。

创建一个带有列404 page not found的表（我以ExceptionsTable为例）。然后在页面顶部的最后一个WordExcepts之后添加以下内容：
DECLARE然后在下面将您的例外情况调整为：
DECLARE @sql nvarchar(2000);
SET @sql = 'N select WordExcepts from ExceptionsTable'
只需根据需要添加到表中，它们就会从函数中过滤掉。
