Hi, I'm struggling with what should be a simple regex and would like some guidance please.

I'm prompting a user to enter a database name and attempting a match on the pattern entered. If it matches a certain set of forbidden names then the user is asked to retry. The database names which are valid consist of alphanumeric and an underscore is also allowed. The system databases are not allowed. Here is what I've got so far .. which isn't working as I expected. 

'[^(master|model|dbccdb|sybsecurity|sybsystemdb|sybsystemprocs|tempdb|
+DBA)][a-zA-Z0-9_]+'

So if they enter any of these names they should be rejected 
master
model
dbccdb
sybsecurity
sybsystemdb
sybsystemprocs
tempdb
DBA

[download]
However the above code is not doing an exact word match like I expected since it's still rejecting valid names e.g. ed123

Any help would be welcome
