Get(UUID)

Returns text representing a Universally Unique Identifier (UUID).

Format

Get(UUID)

Parameters

None

Data type returned

text

Originated in

FileMaker Pro 12.0

Description

Returns a unique 16-byte (128-bit) string. For example, you can use this function to generate a unique ID of a record.

For unstored calculations, returns a new string each time Get(UUID) is evaluated.

Example 1

Auto-enter calculation: In a text field, specify the auto-enter calculation Get(UUID). See Defining automatic data entry.

Every new record has a unique ID in the field—for example:

E47E7AE0-5CF0-FF45-B3AD-C12B3E765CD5

You can use this technique to define a primary key field, if you can’t use the Get(UUIDNumber) function because it requires a later version of FileMaker Pro Advanced.

Example 2

Unstored calculation: In a calculation field, specify the calculation Get(UUID). For Storage Options, select Do not store calculation results. Every time a record is accessed, a new string is generated.
