ibatis 中的Oracle语句中# #好像不生效,不能正确选择出数据(很急)
ibatis 中的Oracle语句中# #好像不生效,不能正确选择出数据(很急)
我原来用的是mysql+ibatis ,最近换成:oracle+ ibatis,原来是可以使用的,但是换成了oracle后,感觉##不正确,不能选择出正确的数据:
resultMap是:
Java code
<resultMap class="menu" id="menuResult">
        <result column="MENUID" property="menuId" />
        <result column="MENUNAME" property="menuName" />
        <result column="TYPE" property="type" />
        <result column="ACTIONID" property="action" select="menu.getActionById" />
        <result column="PARENTID" property="parentId" />
        <result column="SORTORDER" property="sortOrder" />
        <result column="REMARK" property="remark" />
    </resultMap>


Java code

    <select id="getMenu" resultMap="menuResult">
        select * from sys_menu
        <dynamic prepend="where">
            <isNotEmpty property="menu.menuId" prepend="and">
                menuId=#menu.menuId#
            </isNotEmpty>
            <isNotEmpty property="menu.parentId" prepend="and">
                parentId=#menu.parentId#
            </isNotEmpty>
            <isNotEmpty property="roleList" prepend="and">
                exists (select id from sys_rolemenu where
                sys_rolemenu.menuid=sys_menu.menuid
                <iterate property="roleList" prepend="and" open="(" close=")"
                    conjunction="or">
                    roleid=#roleList[].roleId#
                </iterate>
                )
            </isNotEmpty>
        </dynamic>
        order by sortOrder
    </select>


执行过程:
DEBUG - Getting transaction for [net.sansheng.scm.system.service.MenuManageService.getMenuTree]
DEBUG - {conn-100033} Connection
DEBUG - {conn-100033} Preparing Statement: select * from sys_menu where parentId=? order by sortOrder

DEBUG - {pstm-100034} Parameters: [TREEROOT]
DEBUG - {pstm-100034} Types: [java.lang.String]
DEBUG - {rset-100035} ResultSet

可以看出是出入了参数的[TREEROOT] 的,但是选择不出结果:

在oracle中:
select * from sys_menu where parentId='TREEROOT' 是可以选择出数据的;

感觉传递给oracle中,没有将TREEROOT 这个参数增加单引号的感觉,请教大师??急!!!

自己测试了一下,直接写条件是可以的:

DEBUG - {conn-100036} Preparing Statement: select * from sys_menu where parentId=? order by sortOrder
