The syntax for the UID feature in Oracle/PLSQL is:

UID

Parameters or Arguments

There are no parameters or arguments for the UID function.

Returns

Applies To

The UID feature can be used in the following versions of Oracle/PLSQL:

Oracle 12c, Oracle 11g, Oracle 10g, Oracle 9i, Oracle 8i

Example

Let’s seem to be at some Oracle UID function examples and explore how to use the UID characteristic in Oracle/PLSQL.

For example:
