Hequn Cheng updated CALCITE-2198:
---------------------------------
Description:
Currently, makeLiteral for {{BINARY}} and {{VARBINARY}} will throw
{{ClassCastException}} when value type is {{byte[]}}:
{code:java}
java.lang.ClassCastException: [B cannot be cast to
org.apache.calcite.avatica.util.ByteString
at org.apache.calcite.rex.RexBuilder.makeLiteral(RexBuilder.java:1336)
at
org.apache.calcite.test.RexProgramTest.testSimplifyCastLiteral(RexProgramTest.java:1567){code}
The exception can be reproduced by the following test case(in
RexProgramTest.testSimplifyCastLiteral()):
{code:java}
literals.add((RexLiteral)
rexBuilder.makeLiteral(new byte[] {1, 2, -34, 0, -128},
typeFactory.createSqlType(SqlTypeName.BINARY, 5), false));{code}
To avoid this exception we have to add support for type of {{byte[]}}. One
choice is to convert {{byte[]}} to {{ByteString}} in {{RexBuilder.clean()}}.
