Why "create server" statement syntax failed when I copy sample from guide?

Dear All,

   I'm new to SAP IQ, now I have a problem -- in the guide "RFE-Statement", we can see the "create server" should be like --

CREATE SERVER ase_prod

CLASS 'asejdbc'

USING 'banana:3025'

   Now I have an ASE server running on 10.62.47.172:8000. So I use dbisql to run --

create server ase_test class 'asejdbc' using '10.62.47.172:8000'

   But it keeps failing with error --

Could not execute statement.

Syntax error near 'asejdbc'

SQLCODE=-131, ODBC 3 State="42000"

Line 1, column 1

   I really don't know what makes this error. Would anyone kind help? Thanks in advance.

Regards

Eisen
