[jira] [Updated] (CALCITE-1199) Incorrect trimming of CHAR when performing cast to VARCHAR

     [ https://issues.apache.org/jira/browse/CALCITE-1199?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jesus Camacho Rodriguez updated CALCITE-1199:
---------------------------------------------
    Description: 
Assume the value ' ' with type CHAR(1) that needs to be cast to VARCHAR(10).

The method {{makeCast}} (line 488 in RexBuilder.java) trims spaces on the right hand side of the CHAR value, but this seems incorrect as it could lead to incorrect results.
