SQL Error While Applying DDL to Table in Local Database

While Developement with Local Database i faced the error "SQL Error Creating table Dummy Table to Verify Previleges" when i tried to Apply DDL to a table after adding a new column.
I was providing my LOCAL db credentials for the process but it showed following errors.

1.SQL Error Creating table Dummy Table to Verify Previleges , 
2.42000 (-121): [Siebel Database][ODBC Driver][Adaptive Server Anywhere]Permission denied: you do not have permission to use the "CREATE TABLE" statement

for removing the error we need to pass the following credentials rather than Local DB credentials.

UserName : SIEBEL
Pwd : Local DB Password
