Im trying to implement mapping in grails over hibernate for a table which has special characters in columne names. i.e "-"
Mapping in Domain Class
//properties
Boolean h00_02
//mapping
static mapping = {
h00_02 column : 'h00-02'
}

Query: do you have any idea, how can i resolve aforementioned issue. Itried to escape it but it donot work too. I must use aforementioned column name because i m trying to develop UI on exsisting db.
Thanks in advance !
Does this work?
static mapping = {
h00_02 column : '`h00-02`'
}
(Or is that what you mean when you say "I tried to escape it"?)
