在FSQLiteDatabase::PrepareStatement里面对FSQLitePreparedStatement进行初始化,对于FSQLiteDatabase里面的Database,在我们open的时候就已经进行了赋值,所以调用的FSQLitePreparedStatement是带有参数的构造函数。在这个构造函数里面进行Create执行了sqlite3_prepare_v3,同时还对struct sqlite3_stmt* Statement进行初始化。 回到第...

执行SQL语句，如select、insert、update，通常通过FSQLiteDatabase::ExecuteStatement方法进行。这里会创建一个FSQLitePreparedStatement实例，并初始化sqlite3_stmt。在执行查询时，FSQLiteResultSet作为子类提供了结果集的封装，通过FSQLitePreparedStatement实例获取列名和数据类型。这涉及sqlite3_prepare_v3的调用，...
