Generate ssh rsa key from certificate. A unique key is a set of one or more than one fields/columns of a table that uniquely identify a record in a database table.
You can say that it is little like primary key but it can accept only one null value and it cannot have duplicate values.
AppSheet does not provide the capability to generate sequential values. You can certainly create your own mechanism to do so. You are probably aware of UNIQUEID? This is a randomly generated alpha-numeric value guaranteed to be unique. It does NOT need to be a key value. I mention it just in case it helps. Jun 18, 2014 The easy way to make a duplicated code unique is to add a unique number to the end of the code. The easy way to do that is to use the COUNTIF function in combination with the TEXT function to achieve the correct structure for the code. When adding a numeric code to the end of a text code, I highly recommend using leading zeroes with the numbers. To generate an automatically incremented counter for each row that contains data, use an Auto-Number System column. This type of column is useful when you want to automatically include a row ID, a part number, an invoice number, or a customer number without having to type the number in.
The unique key and primary key both provide a guarantee for uniqueness for a column or a set of columns.

There may be many unique key constraints for one table, but only one PRIMARY KEY constraint for one table.
