-845 A PREVIOUS VALUE EXPRESSION CANNOT BE USED BEFORE THE NEXT VALUE EXPRESSION GENERATES A VALUE IN THE CURRENT APPLICATION PROCESS FOR SEQUENCE `sequence-name`

Explanation
 A PREVIOUS VALUE expression specified sequence sequence-name,
but  a value has not yet been generated for this sequence. A NEXT
VALUE expression must be issued in this application process to generate
a value for this sequence before a PREVIOUS VALUE expression for 
the sequence can be issued.
 This error can also occur after
a sequence has been dropped, and the DROP statement is rolled  back.

System action
 The statement cannot be processed.

Programmer response
 Issue at least one NEXT VALUE expression
for a sequence before issuing any PREVIOUS VALUE  expression for the
same sequence in a connection.
