you can pass an array oject, something like

B4X:

Query(Array As Object("SELECT * FROM ART", TRUE))

Note that you don't need to write As Object:

B4X:

Query(Array("SELECT * FROM ART", True))

Another (better) option is to pass a Map:

B4X:

Query (CreateMap("query": "SELECT ..."))

Sub Query(Params As Map)
 Dim q As String = Params.Get("query")
 Dim aLog As Boolean = Params.GetDefault("aLog", True)
End Sub

I don't like these solutions, because they complicate and lengthen the code. I need the 'OptionalParameter' to avoid writing useless code.
Are there any other solutions?

Ok.

As written above optional parameters are not supported.
