Unique ID Definition Methods
Options | Description |
---|---|
Sequential Numeric tag starting at | Assigns an incremental numeric value to each record starting with the number you
specify. If you specify 0, the first record will have an ID
of 0, the second record will have an ID of 1, and so
on. Note: For this Unique Key,
ensure you do not increase the Runtime
instances (in the Runtime
Performance tab) beyond 1 as this can
create duplicate IDs. |
Sequential Numeric tag starting at value in a database field | Assigns an incremental numerical value to each record starting with the maximum
number read from the database field. This number is then
incremented by 1 and assigned to the first record. For
example, if the number read from the database field is 30,
the first record will have an ID of 31, the second record
will have an ID of 32, and so forth.
|
Date/Time stamp | Creates a unique key based on the date and time stamp instead of sequential numbering. |
UUID |
Creates a universally unique 32-digit identifier key for each record. The digits in the key are displayed in five groups separated by hyphens, in the form 8-4-4-4-12 for a total of 36 characters (32 alphanumeric characters and four hyphens). Example: 123e4567-e89b-12d3-a456-432255330000 |
Off | Select this option only if you want to generate a non-unique key using an algorithm. |
