change custom field- column of name column name

-- HikaShop version -- : 2.4.0
-- Joomla version -- : 2.5.28
-- PHP version -- : 5.4

Hi
1) i see when i create custom field that i can't change the name of my custom field (field_namekey) . If i do this in the RDBMS level , joomla return error message .
So after change the name of field_namekey from customdate to product_customdate , then I have an error when i try to use joomla backend to edit this field ( field_realname = customdate ) . I was thinking joomla is base on id but Hikashop use id and something else . Is there a way to check and correct the table *_hikashop_field in a automatic way to correct the issue ?

2) how can i export import custom field with values items, with all options attach to this custom field ?

for

Hi
1)ok
2) I was speaking about import export item of custom field using the joomla backend.
In the capture screen there is no import / export button / icon . So it seem the phpmyadmni way is in many case the way to go !!! what about action mass ? . If i understand well when I import export product items ; import and export custom field is process ( custom field are recreate implicitly !!! if not the case !!! )

3) strange i can't know what the meaning of Core column name by reading the documentation that cover Published the ID !!! nothing about core . core word is cover in delete and label . The documentation say explicitly that we can translate label with core enable but say nothing ( explicitly) if core is disable. Does core enable mean only translation enable ?
