Boomkeeper commented on issue #4963: Single table query with subquery  can not parse with sharding
URL: https://github.com/apache/incubator-shardingsphere/issues/4963#issuecomment-607602897
 
 
   **Is there a temporary solution or emergency solution please？**
   I have encountered a same problem about 'subquery'  recently，and the process of my task also delayed.
   
   something here maybe helpful:
   **version**
   
   > <dependency>
        <groupId>org.apache.shardingsphere</groupId>
        <artifactId>sharding-jdbc-spring-boot-starter</artifactId>
        <version>4.0.1</version>
   </dependency>
   
   **SQL**
   > SELECT COUNT(1) FROM ( 
       SELECT  id, pin, status, created_time, created_by, delete_flag  
       FROM t_table_123
       WHERE  delete_flag = 1
       AND pin IN (?) 
   ) TOTAL
   
   **configuration**
   
   > spring.shardingsphere.encrypt.tables.t_table_123.columns.pin.encryptor=default_encryptor
   spring.shardingsphere.encrypt.tables.t_table_123.columns.pin.plainColumn=pin
   spring.shardingsphere.encrypt.tables.t_table_123.columns.pin.cipherColumn=pin_encrypt
   
   **exception**

   So, what can I do now to avoid exception?
   Thanks.
