    To build on the previous answer, you can use the defaultValue attribute in Grails 2.2 but you need to be careful to put double and single quotes around default values for String properties and double quotes around integer properties so that the default values appear correctly in the DDL. So, for instance, you need to use:

    static mapping = {
       myStringProperty defaultValue: "'Cash'"
       myIntProperty defaultValue: "0"
    }
    

    If you only use single quotes, you will end up with an error like "Column "CASH" not found" Also, as far as I can tell, default values do not work for properties that are enums.
