I'm working on a project using SQL Report Builder 3.0 and using Stored Procedures. The following address displays having line-breaks as it should. I don't notice any difference including 'as [text()]' or not.

Okay, what does 'as [text()] do?

SUBSTRING
((
SELECT companyName + char(10) + address1 + char(10) + address2 as [text()]
FROM Addresses
For XML PATH(''), elements),1,200) as [Mailing_Address]

It names the result column. No more, no less.

It creates an alias for the column.  In this case your column will be called "text()".  The brackets around it are delimiters that allow you to include characters that would otherwise cause a syntax error like a space or parentheses.

I thought it had something to do with SQL Report Builder 3.0... Just a guess...

It is just a column alias. You can execute the query in SSMS and observe the column alias as text().

Naming/Aliasing a column that way may be part of trickery with coe evaluating something, but on the SQL level it simply gives the column name for the expression companyName + char(10) + address1 + char(10) + address2. Without it, the field would be named expr_1, for example, or whatever automatic name would be given.

It's not even specifying the field type TEXT, tha would need a CONVERT or CAST.

Bye, Olaf.
