[GitHub] [shardingsphere] 18811441038 opened a new issue, #24905: sharding-jdbc 集成postgresql 使用 "case when then end" 时抛出 java.lang.NullPointerException: null
18811441038 opened a new issue, #24905:
URL: https://github.com/apache/shardingsphere/issues/24905
**Dear Great Gods：**
I encountered some issues when using sharding-jdbc.
An error occurred when using "case when then end".
**sharding:**
```
<dependency>
<groupId>org.apache.shardingsphere</groupId>
<artifactId>sharding-jdbc-spring-boot-starter</artifactId>
<version>4.1.1</version>
</dependency>
```
**mybatis:**
```
<dependency>
<groupId>com.baomidou</groupId>
<artifactId>mybatis-plus-boot-starter</artifactId>
<version>3.3.1</version>
</dependency>
```
**postgresql**
```
<dependency>
<groupId>org.postgresql</groupId>
<artifactId>postgresql</artifactId>
<version>42.2.14</version>
</dependency>
```
**This problem can occur with both SQL statements, even if I assign a value directly.**
**mybatis-mapper:**
```
<update id="updateBatch">
update r_test
<trim prefix="set" suffixOverrides=",">
<trim prefix="a_aaa = case" suffix="end,">
<foreach collection="list" item="item" >
<if test="item.aAaa != null">
when a_id = #{item.aId} then #{item.aAaa}
</if>
</foreach>
</trim>
</trim>
where
a_id in
<foreach collection="list" item="item" open="(" close=")" separator=",">
#{item.aId}
</foreach>
</update>
<update id="updateBatch1">
UPDATE r_test as a
SET a_aaa =
CASE
WHEN a.a_id = 1 THEN
'aaa'
END
WHERE
a.a_id IN ( 1 )
</update>
```
**The following problem occurred：**
```
