             Summary: Weird digests for literals with some user defined types
                 Key: CALCITE-4510
                 URL: https://issues.apache.org/jira/browse/CALCITE-4510
             Project: Calcite
          Issue Type: Bug
          Components: core
            Reporter: Liya Fan
            Assignee: Liya Fan


We find weird literals for some user defined non-nullable types. Some investigation shows that the problem lies in the {{RexLiteral#toJavaString}} method.

In particular, it checks the type string suffix with an 8-character string:
{noformat}
if (!fullTypeString.endsWith("NOT NULL")) {
{noformat}

However, it trims the last 9 characters from the end of the string:
{noformat}
sb.append(fullTypeString, 0, fullTypeString.length() - 9);
{noformat}
