             Summary: Allow query parameters within the to_date preset query 
function
                 Key: GEODE-3938
                 URL: https://issues.apache.org/jira/browse/GEODE-3938
             Project: Geode
          Issue Type: New Feature
          Components: querying
            Reporter: Juan José Ramos Cassella


Currently the {{to_date}} preset query function doesn't allow the user to pass 
the date to format as a query parameter, which forces the user application to 
add boilerplate code to manually parse the date.
Apparently there's no internal blockers preventing such a feature to be 
enabled, and the change just implies a small change in {{oql.g}}:

{code}
conversionExpr :
  (
    ...
        |
           (  
              (
               
"to_date"^<AST=org.apache.geode.cache.query.internal.parse.ASTConversionExpr>
              )
              TOK_LPAREN!
              (stringLiteral | queryParam) TOK_COMMA! stringLiteral
              TOK_RPAREN! 
           )    
    ...
  )
    ;
{code}
