The uibot database connection is unrecognized error: The object definition error

When defining the database, the connection object is too long, so the object is separated from the definition first, and then database.createdb();

dim a={
//One of the following cases is not allowed
dim a={
//Separating the closing curly brace from the last element does not work.
