Who Can Use a SET GENERATOR?

The SET GENERATOR statement can be executed by:

  • Administrators

  • The owner of the sequence (generator)

  • Users with the ALTER ANY SEQUENCE (ALTER ANY GENERATOR) privilege

Example of SET GENERATOR

Setting the value of the EMP_NO_GEN sequence to 145:
SET GENERATOR EMP_NO_GEN TO 145;
Note

Similar effects can be achieved with [fblangref50-ddl-sequence-alter]:

ALTER SEQUENCE EMP_NO_GEN
  RESTART WITH 145 + increment;

Here, the value of increment is the current increment of the sequence.We need add it as ALTER SEQUENCE calculates the current value to set based on the next value it should produce.
