Anorm, Play, Scala and Postgresql: Dynamic SQL clause not working

Question

I have a problem with using dynamic filter on an SQL query on Postgres, I am using Scala, Anorm and the Play framework. The following query works fine:

val queryTest = SQL("""
  SELECT * FROM myTable
  WHERE (field1 = {field1} OR {field1} IS NULL)
  AND (field2 = {field2} OR {field2} IS NULL)
""").on("field1" -> Some("Foo"), "field2" -> Some("Bar"))
queryTest()

However when a field is set to None, like this:

  val queryTest = SQL("""
    SELECT * FROM myTable
    WHERE (field1 = {field1} OR {field1} IS NULL)
    AND (field2 = {field2} OR {field2} IS NULL)
  """).on("field1" -> Some("Foo"), "field2" -> None)
    queryTest()

I get the following error:

[PSQLException: ERROR: could not determine data type of parameter $4].

When I change the field2 clause this way: AND ({field2} IS NULL OR field2 = {field2}) I get:

[PSQLException: ERROR: could not determine data type of parameter $3]

So the problem seems to be specifically on the {field2} IS NULL.

According to this answer https://stackoverflow.com/a/18308023, it should be working, I don't see where I am going wrong, or maybe it is a specific Postgres issue.

EDIT:

Also, when I set the debug on, I can see the request being sent as:

SELECT * FROM myTable
WHERE (field1 = 'Foo' OR 'Foo' IS NULL)
AND (NULL IS NULL OR field2 = NULL)

And that request works if I paste it in my PostgrSQL client.

EDIT: Here is the stack trace:

Not sure how to check that, the stackTrace says: at anorm.Sql$class.resultSet(Anorm.scala:286) ~[anorm_2.11-2.3.4.jar:2.3.4] — Bentaye

Please try None: Option[String] instead of just None (the conversion of None will probably deprecated at some point as it's not typesafe). — cchantep

I get the exact same error with: .on("field1" -> Some("Foo"), "field2" -> (None: Option[String])). I am using Play version 2.3.4. Actually I am using activator-1.2.3 and all what comes with it. — Bentaye

There is a issue with such undefined value (None) which will be fixed.

For now you can replace the None with null.asInstanceOf[String].
