SQL & PL/SQL
Submitted by cristine_katia on Wed, 2019-11-13 15:21
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
