How to query a CLOB column in Oracle

Question

I\'m trying to run a query that has a few columns that are a CLOB datatype. If i run the query like normal, all of those fields just have (CLOB) as the value.

Answer 1

I did run into another condition with HugeClob in my Oracle database. The dbms_lob.substr only allowed a value of 4000 in the function, ex:

dbms_lob.substr(column,4000,1)

so for my HughClob which was larger, I had to use two calls in select:

select dbms_lob.substr(column,4000,1) part1, 
       dbms_lob.substr(column,4000,4001) part2 from .....

I was calling from a Java app so I simply concatenated part1 and part2 and sent as a email.
