I believe this is a bug in how update SQL statements are parsed when
executing against a linked server. I execute the following SQL:
update [server].[database].[dbo].[table] set [my column] = 'new value'
Note the space in the column name 'my column'. And I get the following
errors:
Server: Msg 8180, Level 16, State 1, Line 1
Statement(s) could not be prepared.
Server: Msg 170, Level 15, State 1, Line 1
Line 1: Incorrect syntax near 'column'.
The syntax of that SQL statement is correct. In fact, I can go to the
linked server and execute it there and it works, like this:
update [table] set [my column] = 'new value'
If I change the schema so the column does not have a space in it, then
execute the following SQL statement from the original server with the server
link, it works:
update [server].[database].[dbo].[table] set [mycolumn] = 'new value'
This to me says that there is a parsing bug because, when performing an
update against a linked server, the quoted identifier for the column is not
respected! Note that this works:
select [my column] from [server].[database].[dbo].[table]
So it appears to be a problem parsing the update statement.
Can anyone shed some light on what is going on? Should I use a support
incident to get this fixed? Or is it something I am doing wrong? Thanks!

The problem happens:
1. Using Query Analyzer
2. In my code, which uses the native SQL Server .NET data provider
I have seen and read a lot of articles and, while they discuss the problem,
and while Microsoft claims they have fixed it in other situations, they have
not fixed it in mine. I would be interested if anyone could reproduce the
problem, or could give me information that would lead to a solution of the
problem. Otherwise I'll be forced to use an MSDN support incident.

The behavior is the same using either double-quotes or brackets.

Since I never use spaces I can't say I have run across this before. Another
option would be to use a stored proc that lives in the other server and call
it to do the update. Good luck. If you still aren't satisfied you can give
MS PSS a call.

I have not seen 4-part naming to be a problem as I am able to do inserts and
updates to tables on the linked server when the table and column names don't
require bracketing or quoting.
The table and column names are highly dynamic, so having a stored procedure
on the linked server is probably not a good option for me. However, I had
not thought of the sp_executesql option, which I will try. What I had
planned on doing (until you came up with the sp_executesql option) was to
name my columns and tables such that they do not have spaces in them, but
rather have the '_' character in them, and then just changing the '_'
character to a space prior to display to the user. I'll try your idea
first.
Will there be any performance consequences vs. normal inserts and updates as
a result of using sp_executesql in the way you have described?
Again, thanks a lot for the help! I really appreciate it.

properly parameterize the changing values. If you are calling multiple
tables or columns you will still be able to cache the plan and reuse it the
next time you call a similar update.
