为什么我的 delete where 语句不起作用？

Question

我正在尝试从 table 个 USERS 中删除一个用户。不幸的是，我一直被发送到 onSqlError。我不知道为什么。当我提醒请求时，它会为我提供 getTheId 变量的正确名称。不太熟悉 sql 所以可能我写错了。任何指针表示赞赏。

// DELETE RECORD
function deleteRecord(getTheId){
    deleteUser.onclick = (function () {//deleteUser is an element generated for each user when a button is clicked
        var sqlStr2 = 'DELETE FROM USERS WHERE username = '+getTheId+'';
        alert("SQL: " + sqlStr2); //This gives me the statement above with the correct name of the user clicked.
        if (db){
            console.log("db is there");//this logs
            db.transaction(function(tx) {  
                   tx.executeSql(sqlStr2);
            }, onSqlError, onSqlSuccess); //THEN I GET SENT TO ERROR
        }
    });
}

Answer 1

尝试添加“;”到你语句的末尾，虽然没有错误消息，但很难判断。

Answer 2

试试这个：

var sqlStr2 = "DELETE FROM USERS WHERE username = '"+getTheId+"'";
