Hi,

naming a table column e.g. "Computer Science"
is not good practice.

I suggest e.g. "ComputerScience"

If you designed the database then it's time to rename the columns.

Best regards,
Stephan

It's bad practice to do that in the first place, but if you've already had,
use:

SQL

Select 'emp firstname lastname', id,branch(computer science as cse) from emptable

Cheers,

In SQL, put square braces around an identifier that has spaces in (this includes column names, table names, triggers, etc.)

Select  [emp firstname lastname], id,branch([computer science] as cse) from emptable

(Update: per below this is for SQL Server only - for standard SQL use a double quote.)

That's only valid for SQL Server, in standard SQL you use a double quote instead of square bracket.

Cool - I didn't know that.

The real solution is probably to not hard-code SQL statements in C# but rather use a data access layer...

Jörgen Andersson 23-Nov-14 5:32am

Indeed it is.
I've been told that the reason SQLServer has it's own convention is so that you don't need to escape quotes in a string which is a common source of confusion.
