Ralph Gasser created CALCITE-3163: ------------------------------------- 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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
