Hi to all,
I have three tables, one reflects article sales, another article purchases and another article regulations.
I would like to make a pursuit of a concrete article from an initial date to another end and to see his history.
The three tables agree in the following fields
code_article, date, units, .......
In order to make a pursuit it would have to unite the three tables ordering per dates and later to select the rank of dates selec.
How I can do this? How I can to place a table underneath another one?
Tk very much.
