I am unable to get char data type number data type and date data type information from a record group.
How will i come to know about data type as like i have a record group as select id,name from mytable.
now if i have id as number then i may use get_number_group and if id is character then get_character_group but if i changed the number to character
in the background from table data structure then it will give error. how to skip from such errors.
you may get error in get_number property if you receive a character filed in your query.
so you may use select to_char(number_field),to_char(date_field,'dd-mon-yyyy') .... etc in your record group query.
