T_TABLE2的结构是

ID INT
TBL1_ID INT
TESTER VARCHAR
LOT_ID VARCHAR
GRP VARCHAR
SITE_NUM INT
TEST_NUM VARCHAR
TEST_DESC VARCHAR
MEASUREMENT DOUBLE PRECISION
UNIT VARCHAR
LL DOUBLE PRECISION
UL DOUBLE PRECISION
STATUS VARCHAR

我在firebird中使用SQL编辑器测试我的查询.查询是

SELECT TEST_DESC, MEASUREMENT, LL, UL 
FROM T_TABLE2 
GROUP BY TEST_DESC

但我在分组中得到了这个错误.

Invalid token.
Dynamic SQL Error.
SQL error code = -104.
Invalid expression in the select list (not contained in either an aggregate function or the GROUP BY clause).

我有Angular材质导航栏(如下所示).我在导航栏中放了一个md菜单,因为我想实现右侧有下拉菜单的bootstrap导航栏.如何移动"WELCOME!IVAN",这是右侧的下拉菜单.

下面是我的代码:

<div ng-controller="navController">
<md-content>
    <md-nav-bar md-selected-nav-item="currentNavItem" nav-bar-aria-label="navigation links">

        <md-nav-item md-nav-href="#{{ link.url}}"  ng-repeat="link in navUrl" name="{{ link.url.substr(1)}}">
            <i class="fa {{ link.icon}}" aria-hidden="true"></i>
            &nbsp;&nbsp;{{ link.link}}
        </md-nav-item>

        <md-menu md-offset="0 -7" layout-align="end center">
            <md-button aria-label="Open menu" class="md-button" ng-click="$mdMenu.open($event)">
                Welcome! {{ user}}
                <!--<md-icon md-menu-origin md-svg-icon="call:phone"></md-icon>-->
                <i class="fa fa-user" aria-hidden="true"></i>
            </md-button>
            <md-menu-content width="3">
                <md-menu-item>
                    <md-button ng-click=""> <span md-menu-align-target>Logout</span></md-button>
                </md-menu-item>
            </md-menu-content>
        </md-menu>

    </md-nav-bar>

</md-content>

在此先感谢您的帮助!!!:)
