      1 - Create a reference data table that has a column with literal name of "value"
      2 - Use the LOOKUP function with the "value" column in the keyColumn field (3rd argument)

      1 - Create a reference data table that has a column with literal name of "value" 2 - Use the LOOKUP function with the "value" column in the keyColumn field (3rd argument)

      When using the Teiid LOOKUP function, the 3rd argument is to specify the keycolumn. In my table, the column I want to reference is literally named "value", which is a SQL reserved word. The generated query chokes on this because it's not expecting a reserved word to be here when parsing the grammar. I've tried quoting and escaping to get around this, but nothing seems to work.
