问题 One of the jobs of OJDBC is to map Oracle data types to Java types. However, we noticed that if we give a CHAR data type, it is not mapped to java.lang.String . The versions showing this behavior are: OJDBC7 v12.1.0.2 and OJDBC6 v12.1.0.1 . The older versions did indeed map the CHAR data type to: java.lang.String . On digging deeper, we discovered that there is a class: StructMetaData within the oracle.jdbc.driver package of OJDBC that implements the Oracle data type to Java Type mapping.
