柔性本地數據庫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); 

我做了一個本地數據庫和我試圖插入一些數據，但 我得到lastInsertId零？我把事情搞亂了！？

您不需要額外執行查詢來檢索上次插入的行的id。爲此目的，SQLResult類有一個內置的.lastInsertRowID屬性。只要使用這樣的：

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);
