azraelee opened a new issue #5797:
URL: https://github.com/apache/shardingsphere/issues/5797
这个是我的项目sql:
update xxx_table
<trim prefix="set" suffixOverrides=",">
<trim prefix="column1= case" suffix="end," >
<foreach collection="list" item="item" index="index">
<if test="item.column1 != null">
when id = #{item.id} then #{item.column1}
</if>
</foreach>
else column1
</trim>
<trim prefix="column2 = case" suffix="end," >
<foreach collection="list" item="item" index="index">
<if test="item.column2 != null">
when id = #{item.id} then #{item.column2}
</if>
</foreach>
else column2
</trim>
</trim>
where
<foreach collection="list" item="item" open="( " separator=") or ("
close=" )">
id = #{item.id}
</foreach>
当解析 <trim prefix="column1= case" suffix="end," > 这句时,
执行CaseExpressionContext#simpleExpr() 会返回空指针异常
