MyBatis, UPPER in a where condition - mybatis

Question

I have to do a select query with a lot of parameters in MyBatis, I want to use the default mapper xml file structure and add an "UPPER(column_name) = ?" to the result converted query. How Can I do ?
Here is my where clause
<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>
and here is the complete select statement:
<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>
I always receive error like this one
The error occurred while setting parameters
...
WHERE ( UPPER(id_metadato = ?) and UPPER(valore = ?) )
I feel I'm near to the solution, but I can't find a way. Thanks to all

I resolved my problem, specs were changed and now I do not need the upper anymore.
By the way before that I handled that problem changing the mybatis like query language to pure SQL language.
