I have a database table that looks like:
create table answers(
id int not null,
question_id int not null,
answer text null
)
This table was originally build by Hibernate using the @Lob attribute for the "answer" column. I did not realize it at the time, but when setup that way, Hibernate stores an OID in the column instead of the actual text. Everything works fine when I use Hibernate to retrieve the values since it automatically converts the OID to the CLOB string, however it is becoming a performance problem and I'd like to get rid of the OID.
select * from answers
ID QUESTION_ID ANSWER
===============================
1 123 55123
2 234 51614
3 345 56127
should be
ID QUESTION_ID ANSWER
===============================
1 123 Male
2 234 203-555-1212
3 345 555 Main St. New York, NY
My desire is to add an extra column to the table "ANSWER_VALUE TEXT" and do something like below to get the actual value into the table, then change Hibernate around to not use the @Lob designator
update answers set ANSWER_VALUE= getValueFromOID(ANSWER)
Does that "getValueFromOID" function exist? If not, could I get some pointers on how to create one or at least how to fetch the actual value of an OID?
Thanks
