How do you create an equi-join?

Answer by  maritzae (49)

An equi join is a statement that compare two or more columns from different tables. You have to use an equivalence to match a column from one table with the column of other different table. For example : colX=colY where colx belongs to table a and colx belongs to table b .

You have to write a lot of code, and must have knowledge of mySQL. Equi-join is an extension of join classes, but only return you values if they appear on all data sets you give them.
