我们在我们的应用程序中使用SQLite数据库。我们有足够的选择，更新和插入SQLite操作。我们的应用程序在CrashAnalytics中以下堆栈跟踪随机崩溃。

以下是SQLite代码：

sqlite3_stmt *statement=NULL;
NSString* accountType = NULL;
NSString *querySQL = [NSString stringWithFormat: @"SELECT a_type FROM account_detail WHERE aname=\"%@\"", accountName];
const char *query_stmt = [querySQL UTF8String];
if (sqlite3_prepare_v2(dbNameCompany, query_stmt, -1, &statement, NULL) == SQLITE_OK) //Line 6677 of DataHelper.m
{
    if (sqlite3_step(statement) == SQLITE_ROW)
    {
        accountType = [[NSString alloc] initWithUTF8String:(const char *) sqlite3_column_text(statement, 0)];
    } 
    else 
    {
    }
}
sqlite3_finalize(statement);
return accountType;
