strongduanmu opened a new issue, #27287:
URL: https://github.com/apache/shardingsphere/issues/27287

   In the issues reported by the community, we can often see exceptions caused 
by asterisk expansion errors, such as `Column index out of range`, and 
exceptions caused by sql execution errors in the sharding and encrypt functions.
   
   These problems affect the sql support of shardingsphere. In order to solve 
these problems, we need to reconstruct the asterisk expansion logic in 
ProjectionEngine#createProjection, and perform asterisk expansion on statements 
such as simple query and associated query according to the characteristics of 
different databases.
   
   The following is MySQL's description of the asterisk expansion logic,  we 
will implement asterisk expansion according to the behavior of different 
databases.
