A username and/or password was expected on the command line. Null is being used Explanation: In a DECLARE ALIAS statement the DEFAULT keyword was used in place of the actual username or password. The necessary qualifiers were not provided in the compilation command line, so a null is being used. User Action: Compile the module again and provide the necessary username and/or password qualifiers. For SQL$MOD use /USERNAME=username /PASSWORD=password. For SQL$PRE use /SQLOPTIONS=(USERNAME=username,PASSWORD=password).
