MyBatisダイナミックSQLインクルードプロパティを使用する

Question

共通SQLタグが含まれている場所によって動的に変更する必要があります。

<sql id="common"> 
     from customer_order as co inner join status as st on st.id = co.status_id 
     left join status as sst on sst.id = co.sub_status_id 
     inner join customer as c on c.id = co.customer_id 
     inner join user as u on u.id = co.created_by 
     left join customer_account as acc on acc.id = c.account_type_id 
     left join customer_type as typ on typ.id = c.party_type 
     left join sale_channel as ch on ch.id = co.saleschannel_id 
     <choose> 
     <when test="${ordernotes} eq 'true'"> 
      inner join order_note as ordn on ordn.order_id = co.id 
     </when> 
     <when test="${vendorordernotes} eq 'true'"> 
      ... join with other tables 
     </when> 
     </choose> 
</sql> 

これは、上記のSQLを含む方法です。

<select id="x" resultType="long"> 
     select count(distinct ordn.id) 
     <include refid="common"> 
      <property name="ordernotes" value="true"/> 
     </include> 
    </select> 

そして

<select id="y" resultType="long"> 
     select count(distinct von.id) 
     <include refid="common"> 
      <property name="vendorordernotes" value="true"/> 
     </include> 
</select> 

私は '' コードを動作させることはできません。どのように私はそれについて行くのですか？

例外：それはうまく解釈されません

パラメータ。 サラウンドパラメータの引用符：<when test="'${ordernotes}' eq 'true'">、それは単純な文字列となります。
