[GitHub] [incubator-shardingsphere] lianqiuye opened a new issue #2956: Sharding-JDBC can not convert LONGTEXT data in MySql to java.sql.Clob

lianqiuye opened a new issue #2956: Sharding-JDBC  can not convert LONGTEXT data in MySql  to java.sql.Clob
URL: https://github.com/apache/incubator-shardingsphere/issues/2956
 
 
   Sharding-JDBC Version: 4.0.0-RC2
   
   org.apache.shardingsphere.core.execute.sql.execute.result.QueryResultUtil convert column data to crossponding java Object by ResultSetMetaData, but the target data type may be a compatible java type.
   
   Suggestion:
   Mysql driver restore LONGTEXT as String as default, but if caller ask for java.sql.Clob type, the driver will convert to clob silently. The QueryResultUtil  should consider the target type and ask the driver  to convert to the target type.
