CURRENT_ROLE

Available in: DSQL, PSQL

Added in: 1.0

Description

CURRENT_ROLE is a context variable containing the role of the currently connected user. If there is no active role, CURRENT_ROLE is NONE.

Type: VARCHAR(31)

Example 

if (current_role <> 'MANAGER')
  then exception only_managers_may_delete;
else
  delete from Customers where custno = :custno;

CURRENT_ROLE always represents a valid role or NONE. If a user connects with a non-existing role, the engine silently resets it to NONE without returning an error.
