我必须在MyBatis中使用大量参数进行选择查询,我想使用默认的映射器xml文件结构并添加" UPPER(column_name)=?"到结果转换查询。我该怎么办?

这是我的where子句

<sql id="My_Select">
    <where>
        <foreach collection="oredCriteria" item="criteria" separator="or">
            <if test="criteria.valid">
                <trim prefix="(" prefixOverrides="and" suffix=")">
                    <foreach collection="criteria.criteria" item="criterion">
                        <choose>
                            <when test="criterion.noValue">
                                and ${criterion.condition}
                            </when>
                            <when test="criterion.singleValue">
                                and UPPER(${criterion.condition} #{criterion.value})
                            </when>
                            <when test="criterion.betweenValue">
                                and ${criterion.condition} #{criterion.value}
                                and
                                #{criterion.secondValue}
                            </when>
                            <when test="criterion.listValue">
                                and ${criterion.condition}
                                <foreach close=")" collection="criterion.value" item="listItem"
                                    open="(" separator=",">
                                    #{listItem}
                                </foreach>
                            </when>
                        </choose>
                    </foreach>
                </trim>
            </if>
        </foreach>
    </where>
</sql>

这是完整的选择语句:

<select id="mySelect" parameterType="myDataExample"
    resultMap="myResultMap">
    select
    <if test="distinct">
        distinct
    </if>
    <include refid="my_Column_List" />
    from istanza_metadato
    <if test="_parameter != null">
        <include refid="My_Select" />
    </if>
    <if test="orderByClause != null">
        order by ${orderByClause}
    </if>
</select>

我总是收到像这样的错误

设置参数时发生错误

...

WHERE(UPPER(id_metadato =?)和UPPER(valore =?))

我觉得我接近解决方案,但我无法找到方法。感谢所有
