How to Create Key Index Fields with Five's Table Wizard​

Learn how to create key index fields with Five's Table Wizard. This is the final tutorial in a series of four videos.



info
Key Fields are used to find rows with specific column values quickly. Without a key field, each entire row starting from the first row needs to be read in the table to find the relevant rows. If your table has a key field, Five can quickly determine the position to seek to without having to look at all the data. This makes performing a query on the table much faster than reading every row sequentially. You can also use the Key Fields section to make a field unique.
