concat dynamic arrays via IDs

Dear Friends:

The scenario is as follow. In G3# I have a dynamic array, 2 cols, with an ID, and a value1. in J3#, another dynamic array, 2 cols, with an ID, and a value2.

I need to concat each value 1 with all corresponding values2 depending on the ID, and return an array in M3# listing all the results.
