   > > From the screenshot，we can find that the **dataTypeMap** does not contains the dataType `'4'`, because the **dataTypeMap** is the TYPE_NAME to DATA_TYPE mappings, just like below

   > * An extra topic is that in the previous H2DataBase mail list, this was pointed out as an error design of H2DataBase V1. Refer to [Update H2DataBase to 2.x and drop support for H2Database 1.x #19964](https://github.com/apache/shardingsphere/pull/19964) . Because there is no way to test H2Database V1 in the unit test, I am not sure that similar operations are helpful for H2DataBase V1.
   
   Thanks. So do you mean that I need to upgrade my H2 version from V1 to V2 ? Now shardingsphere-jdbc can work with this error, but I don't know if it will cause other errors.
