Question

我正在尝试从表USERS中删除用户。不幸的是，我一直被发送到onSqlError。我无法弄清楚为什么。当我提醒请求时，它为我提供了getTheId变量的正确名称。不太熟悉sql所以也许我写错了。任何指针赞赏。

// 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

试试这个：

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

Answer 2

尝试添加';'在你的陈述结束时，虽然没有错误信息，但很难说。

为什么我的删除where语句不起作用？
