Re: function with different return type depending on parameter?

[Pavel Stehule <pavel.stehule@xxxxxxxxx>]

Hello

no it is not possible

Regards

Pavel

p.s. result - type must be known before execution (when execution plan is created)

2014-02-12 10:20 GMT+01:00 James Harper <james.harper@xxxxxxxxxxxxxxxx>:

is it possible to have a function that can return a different type depending on the parameters? Eg (approximately)

if param = "one" then return 1
if param = "two" then return "2"
if param = "three" then return 3.0
etc

I can't see any variant type

thanks

James
