SQL - 将每个单词的首字母大写

Question

I know that this thread exists all over the place, however, this is a slightly different case. In the suite my company uses, I have limited access to the SQL and cannot run the complicated codes with functions, etc. I had a SQL query that compiled data over multiple columns into one column and used a group by clause to weed out multiplicities. However, this caused all the results to be returned in all caps, since variations existed. I must now change it back to how it should be, ie first letter of each word capitalized. I need a very concise way of doing this. The suite uses VBScript and XML, but this particular issue is more complicated because I cannot edit the results on the client-side, the suite simply asks for the column name to be displayed (populate a drop-down menu). Any suggestions? Thanks!

You did not say that this was for SQL Server but here is a solution in case it is.

Here is a working sample. Replace the table variable @T with the query you have.

declare @T table(Insurance varchar(max))

insert into @T values
('BENGT MIKAEL ERIKSSON'),
('XMLCHARTEST<>&''"')

select (
       select upper(T.N.value('.', 'char(1)'))+
                lower(stuff(T.N.value('.', 'varchar(max)'), 1, 1, ''))+' '
       from X.InsXML.nodes('/N') as T(N)
       for xml path(''), type
       ).value('.', 'varchar(max)') as Insurance
from 
  (
  select cast('<N>'+replace(
                    replace(
                    replace(Insurance,
                    '&', '&amp;'),
                    '<', '&lt;'),
                    ' ','</N><N>')+'</N>' as xml) as InsXML
  from @T
  ) as X

Result:

Insurance

This will uppercase the first letter of the string. If there are multiple words, this is better done in the application layer. You would likely need to write a SQL function to do this.

select upper(substring(MyColumn, 1, 1)) + substring(MyColumn, 2)
from MyTable

or

select upper(substring(MyColumn, 1, 1)) || substring(MyColumn, 2)
from MyTable
