I have two tables which are identical. They are named differently but the column names and lengths are the same.
The difference between the two is that the second table "Table_Hash" has no primary key on the "ID" column.
Basically I am using Table_Hash as a table to hold values from "Table_First".
Is it okay that my table column in Table_Hash has a column named the same as Table_First "ID". No primary key is assigned in Table_Hash ?
-- Rough example :
-- Table hash is identical to Table_First but with no primary key asssigned to "ID"
