我想问下面我的功能.当我调用此函数时,它打印不可用.请问你能帮帮我吗？？

    static sqlite3 *database = nil;
    static sqlite3_stmt *statement = nil;

    - (BOOL) findNews:(NSString *)caption{   
    const char *dbpath = [databasePath UTF8String];
    if (sqlite3_open(dbpath, &database) == SQLITE_OK)
    {
        NSLog(@"CAPTION ID : %@", caption);
        NSString *querySQL = [NSString stringWithFormat:@"SELECT * FROM dbase WHERE CONTENT_ID = \"%@\"", caption];
        const char *query_stmt = [querySQL UTF8String];

        if (sqlite3_prepare_v2(database, query_stmt, -1, &statement, NULL) == SQLITE_OK)
        {
            if (sqlite3_step(statement) == SQLITE_ROW)
            {
                return YES;
            }
            else{
                return NO;
            }
            sqlite3_reset(statement);
        }else{
            NSLog(@"NOT AVAILABLE");
        }
    }
    return nil; …
