Copying Column Properties to a Foreign Key Column

When you copy a column from one table to another table, the column name and many of the other properties you defined for that column in the table are copied to the new location. You can copy column properties from a primary key column to a foreign key column if you want to relate the two columns. Related columns must have the same data type (or data types that can be related) and Length property settings.
