About method "[BZObjectStore inTransactionWithBlock:]"
Hello expensivegasprices.
Today , I using BZObjectStore in Multithreading , i got a log .
The FMDatabase <FMDatabase: 0x17009c390> is currently in use.
I see the source code ,i found [BZObjectStore inTransactionWithBlock:] method .
- (void)inTransactionWithBlock:(void(^)(FMDatabase *db,BOOL *rollback))block
{
if (self.db) {
if (block) {
block(self.db,&_rollback);
}
} else {
[self.dbQueue inTransaction:^(FMDatabase *db, BOOL *rollback) {
[_weakSelf transactionDidBegin:db];
_weakSelf.db = db;
[db setShouldCacheStatements:YES];
block(db,rollback);
if (*rollback) {
[_weakSelf setUnRegistedAllRuntimeFlag];
}
}];
[self transactionDidEnd:self.db];
self.db = nil;
}
}
I think doing this will cause querying results incorrect
join fetch in BZObjectStore
When we fetch objects like this sql:
select * from tableA a join tableB b on b.a_id = a.id where b.XXX = XXX
is there any solution in BZObjectStore?
some errors

Any idea?
maybe BZJSON？
maybe you can create a new JSON Model project..
