Description

Considering chinook tests, having following schema:

 {
  "version": "1.0",
  "defaultSchema": "ENHANCED",
  "schemas": [
    {
      "name": "CHINOOK",
      "type": "jdbc",
      "jdbcDriver": "org.hsqldb.jdbc.JDBCDriver",
      "jdbcUrl": "jdbc:hsqldb:res:chinook",
      "jdbcUser": "sa",
      "jdbcPassword": ""
    },
    {
      "name": "ENHANCED",
      "type": "custom",
      "factory": "org.apache.calcite.schema.impl.AbstractSchema$Factory",
      "operand": {},
      "tables": [
  ...
        {
          "name" : "SIMPLE_CUSTOMER",
          "type" : "view",
          "sql" : [
            "SELECT c.firstname, c.lastname, c.email ",
            "FROM chinook.customer AS c"
          ]
...
      ],
      "functions": [
        {
          "name": "ASCONCATOFPARAMS",
          "className": "org.apache.calcite.chinook.StringConcatFunction"
        }
      ]
    }
  ]

Following query produces error:

SELECT email, ASCONCATOFPARAMS(firstname, lastname) AS joined FROM SIMPLE_CUSTOMER limit 3

Exception:
