Good afternoon people!
I have a procedure in Oracle with various functions of calculations, type simulator. So, I want to assemble a type with output parameters reading this data and bring the results of these functions in real time, because I want to display them as output lines on a front (web screen). I already created the types objects and table. However, I am having difficulty assembling, because I do not know well Type. Can someone help me? Thanks

A very nice licensing change in 19c: you can now have up to three PDBs in a Standard Edition Multitenant database.
