ORA-22831: Offset or offset+amount does not land on character boundary

问题

I am getting error during Oracle Apex 4.2 application export.

ORA-22831: Offset or offset+amount does not land on character boundary

回答1:

Are you using the LENGTH or the DBMS_LOB.SUBSTR function in any of your plsql code? If so you could take a look into LENGTHB and SUBSTRB.

LENGTHC or SUBSTRC may help as well
