cordova - 如何从phonegap android中的sqlite获取最后插入的行ID

Question

我正在创建一个应用程序，在该应用程序中我在表中插入数据。在表中插入数据后，我想获取该行的 id，以便我可以根据它进行进一步的操作。我尝试使用sqlite 的last_insert_rowid()函数，但没有运气。任何人都可以告诉哪个是获取最后插入的行ID的最佳方法。任何想法都值得赞赏。提前致谢。

Answer 1

您可以像这样在表上获取最后插入的 id -

tx.executeSql("INSERT INTO profile('name','label','list_order','category') values(?,?,?,?)", 
    [currentProfile.name, currentProfile.label, currentProfile.list_order, currentProfile.category], 
    function(tx, results){
        var lastInsertId = results.insertId; // this is the id of the insert just performed
    }, 
    failCB
)

results.insertIdWebSQL 中的与mysql_insert_id()MySQL中的类似 -

mysql_query("INSERT INTO mytable (product) values ('kossu')");
printf("Last inserted record has id %d\n", mysql_insert_id());

Answer 2

Do you have a column in your table named rowid, oid, or _rowid_? If you do, that will cause an issue with last_insert_rowid() working as intended. See here.

A workaround: If you have an ID column that is auto-incremented, you could use the following SQL to get the last entry.

SELECT * FROM yourTable ORDER BY yourIdColumn DESC LIMIT 1

It's hacky, but it would work.
