[Mybatis] How to Solve the problem of Oracle query processing more than 1000 in conditions

Go directly to SQL. The idea is very simple

select * from test_table
where 1 = 1 
 <!-- IdList -->
 <if test="IdList != null and IdList.size > 0">
     AND PK_ID IN
    <!-- Handle the case where Oracle does not support in when the set of in exceeds 1000 entries -->
    <trim suffixOverrides=" OR PK_ID IN()">    <!-- means delete the last condition -->
        <foreach collection="IdList" item="Id" index="index" open="(" close=")">
            <if test="index != 0">
                <choose>
                    <when test="index % 1000 == 999">) OR PK_ID IN (</when>
                    <otherwise>,</otherwise>
                </choose>
            </if>
            #{Id}
        </foreach>
    </trim>
 </if>
