oracle - Type inacurracy -

-

i'm trying create entity data model using visual studio 2012 , oracle 10g. i'm getting error:

error 1 running transformation: types of properties in dependent role of referential constraint must same corresponding property types in principal role. type of property 'quartal_sec_id' on entity 'model.quartal' not match type of property 'sec_id' on entity 'model.sec' in referential constraint 'fk_quartal_sec_id'.

indeed sec_id has number(32) , quartal_sec_id - number(10) in database. can't change there. have changed both types in mapping details in vs12 int32. doesn't help. possible solve problem in vs12? can force accept different values in foreign keys?

i can't map number(10) (ora) decimal(vs) cause additional err:

error 2 error 2019: member mapping specified not valid. type 'edm.decimal[nullable=false,defaultvalue=,precision=,scale=]' of member 'quartal_sec_id' in type 'model.quartal' not compatible 'oracleefprovider.number[nullable=false,defaultvalue=,precision=10,scale=0]' of member 'quartal_sec_id' in type 'model.store.quartal'.

i using ef 5 oracle , number types have our entity properties set decimals.

this article outlines data types.

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.

erlang - Saving a digraph to mnesia is hindered because of its side-effects -

-
updated the digraph library in erlang implements data type side-effectful. each operation on data type saves new state in ets table -- instead of returning altered version of itself, more common in functional languages. the problem usage perspective, impedes effort store or pass around state in convenient way requiring me first "collect" state before can start juggle around. the closest solution have seen far serializer/deserializer , these have drawback tied current structure of digraphs instead of operating on abstract type -- prevents future proof solution. update pascal pointed out serializer utilizes interface of digraph, , hence eliminates drawback mentioned above. better, albeit still inconvenient, see no better alternative. what recommendation on how store digraphs? should go different data type altogether? thanks. i not sure understand concern. fact digraph stored in ets transparent in user interface, might want chnge either exchange digr...
