Multidimensional arrays in SQLScript

Hi dear experts,

I have two questions that are related to the project I'm currently working on:

1) is there any possibility to declare an multidimensional array in the SQLScript-based procedure ?

2) I'm actually trying to use table types (instead of arrays), but how could I access the specific table filed of the input table in my procedure:

CREATE PROCEDURE simpl (in intab tableau, in i integer, out outtab tableau)

AS

BEGIN

outtab= select top 10 from :intab where :intab.X = :i;

END;

tableau has three columns: A, B, C (type integer)

Thanks in advance!
