Problem Symptoms:
Running SQL to change sublibrary of certain XXX50 Z305 (PATRON?€™S LOCAL INFORMATION) records from 'YYYYY' to ' ZZZZZ':

UPDATE Z305
SET Z305_REC_KEY = substr(Z305_REC_KEY,1,12) || 'ZZZZZ'
where substr(Z305_REC_KEY,13,5) = 'YYYYY'

results in the following message:

Error:
*
ERROR at line 1:
ORA-00001: unique constraint (XXX50.Z305_ID) violated

Cause:
SQL didn't include check to see if a "ZZZZZ" record already existed for the patron.

Resolution:
Add check to see if a "ZZZZZ" record already exists for patron:

UPDATE Z305
SET Z305_REC_KEY = substr(Z305_REC_KEY,1,12) || 'ZZZZZ'
where substr(Z305_REC_KEY,13,5) = 'YYYYY'
and substr(Z305_REC_KEY,1,12) not in
(select substr (Z305_REC_KEY,1,12) from z305 where substr (Z305_REC_KEY,13,5) = 'ZZZZZ');
