             Summary: Mapping of Types in AbstractCursor#convertValue() does 
not adhere to JDBC specification
                 Key: CALCITE-3163
                 URL: https://issues.apache.org/jira/browse/CALCITE-3163
             Project: Calcite
          Issue Type: Bug
          Components: avatica
    Affects Versions: avatica-1.15.0
            Reporter: Ralph Gasser


This is an issue I found while working on CALCITE-3162: According to my 
understanding, the method _AbstractCursor#convertValue()_, used for converting 
the component types of ARRAYs, does not adhere to what is specified in the 
[JDBC 
specification|[https://download.oracle.com/otn-pub/jcp/jdbc-4_1-mrel-spec/jdbc4.1-fr-spec.pdf?AuthParam=1561978725_eefb6fb1703d96f182674508c44126ea]]
 (Appendix B) regarding mapping of types:
 * The JDBC types FLOAT (6) and DOUBLE (8) should actually both map to Java 
_double_ or _Double_ respectively. Currently, FLOAT (6) is converted to a 
_float_.
 * The implementation is currently missing support for JDBC type REAL (7), 
which should convert to _float_ or _Float_ respectively

This issue will cause an IllegalStateException to be thrown in clients using 
the Avatica Driver, if they encounter REAL datatype in arrays.
