i am using ASE 15.0 version.
When i am creating new encryption key, i am getting the error.

my syntax is:
create encryption key item_key as default for algorithm

Error :
Msg 156, Level 15, State 2:
Server 'PRODSRV', Line 1:
Incorrect syntax near the keyword 'for'.

So i tried to create the key w/o any further options.

but still i am not able to create it.

configuratio parameter 'enable encryption columns' is 1

Referrence :

According to reference document, my syntax is not wrong but still it is showing incorrect syntax.

Can any one tell me the solution for this.....
