What's Wrong?

databend should sustain case-sensitive for query alias names, this is very important for mybatis mapping to the java object. And this function shouldn't be controlled by 'unquoted_ident_case_sensitive' due to they are not the same thing

How to Reproduce?

If this occurring, mybatis can't map db fields to java object, this is terrible for business system migrating to databend. And this function shouldn't be controlled by 'unquoted_ident_case_sensitive' due to they are not the same thing, still needing to convert some where clauses to lower case.

Maybe you need:

select order_id as `orderId` from blob_test limit 5;
