flex本地数据库lastInsertId = 0

Question

var insertReq:SQLStatement = new SQLStatement(); 
insertReq.addEventListener(SQLErrorEvent.ERROR, dbErrorHandler);
insertReq.sqlConnection = conn; 
insertReq.text = "INSERT INTO table1 (inputTime) VALUES (DATETIME('now'))";
insertReq.execute();
insertReq.text = "SELECT last_insert_rowid() as ID";
insertReq.execute();
var lastInsertId:int = insertReq.getResult().data[0].id;
trace(lastInsertId);

我创建了一个本地数据库，我试图插入一些数据但是 我得lastInsertId为零？！我搞砸了什么东西！？

您无需额外执行查询以检索最后插入的行的id。为此，有.lastInsertRowID类的内置SQLResult属性。只需使用它：

var insertReq:SQLStatement = new SQLStatement(); 
insertReq.addEventListener(SQLErrorEvent.ERROR, dbErrorHandler);
insertReq.sqlConnection = conn; 
insertReq.text = "INSERT INTO table1 (inputTime) VALUES (DATETIME('now'))";
insertReq.execute();
var lastInsertId:int = insertReq.getResult().lastInsertRowID;
trace(lastInsertId);
