[QT4][SQLITE] Database and query

[agent007se]

Hello !

I'm trying to have a very little db. My knowledges in db are poor but I just want to know how can I set a minimal db i.e. :

MAIN_TREE
entry1
...(1->L)
entryL
    SUB_TREE1
        entry1
        ...(1->I)
        entryI
    SUB_TREE...(1->N)
        entry1
        ...(1->J)
        entryJ
    SUB_TREEN
        entry1
        ...(1->K)
        entryK

MAIN_TREE
entry1
...(1->L)
entryL
    SUB_TREE1
        entry1
        ...(1->I)
        entryI
    SUB_TREE...(1->N)
        entry1
        ...(1->J)
        entryJ
    SUB_TREEN
        entry1
        ...(1->K)
        entryK

To copy to clipboard, switch view to plain text mode 

The entries will just be a list of files (and their path).

I'm really noob because my very little code doesn't work :

.h file:

QSqlQuery *query;

QSqlQuery *query;

To copy to clipboard, switch view to plain text mode 

.cpp file:

[post edit :] query = new QSqlQuery(db);
bool tst = query->exec("CREATE TABLE person");

[post edit :] query = new QSqlQuery(db);
bool tst = query->exec("CREATE TABLE person");

To copy to clipboard, switch view to plain text mode 

=> lol. I have a segfault... edit : The segfault is gone but... there isn't any table in the file which is correctly created. The result of the query is "false". But I wonder why... it seems to be a basic query...
