| delete_all_entries/1 | delete all entries in the mnesia table MnesiaTab. |
| delete_record/1 | wraps mnesia:delete_object in a transaction context NOTE: Record MUST have the same name as the table it is inserted into Returns : mnesia:transaction(). |
| delete_with_key/2 | wraps mnesia:delete({Db, Key}) in a transaction context. |
| generic_table_info/2 | Get mnesia table information, regardless of where table resides. |
| insert_record/1 | wraps mnesia:write in a transaction context. |
| match_object/1 | alternative match_object based on mnesia:select/2 it should be faster than mnesia:match_object/1. |
| tab_to_list/1 | return a list with all entries in MnesiaTab Note : This is a time and memory consuming operation if the table is large. |
delete_all_entries(MnesiaTab) -> term()
delete all entries in the mnesia table MnesiaTab
delete_record(Record) -> term()
wraps mnesia:delete_object in a transaction context NOTE: Record MUST have the same name as the table it is inserted into Returns : mnesia:transaction()
delete_with_key(Db, Key) -> term()
wraps mnesia:delete({Db, Key}) in a transaction context
generic_table_info(Tab, Item) -> term()
Get mnesia table information, regardless of where table resides.
insert_record(Record) -> term()
wraps mnesia:write in a transaction context. NOTE: Record MUST have the same name as the table it is inserted into
match_object(Pattern) -> Records
alternative match_object based on mnesia:select/2 it should be faster than mnesia:match_object/1. Finds the records that match the pattern Pattern. Pattern is usually something like: #rec_name{f1 = V1, f2 = V2, ..., _ = '_'} where '_' acts as a wildcard value NOTE : the record name must be = table name. '$number' (e.g. '$1', '$2', .... ) can not be used in Pattern (it has special meaning in the match specification used by mnesia:select/1)
tab_to_list(MnesiaTab) -> [records]
return a list with all entries in MnesiaTab Note : This is a time and memory consuming operation if the table is large
