Satheesh Bandaram commented on DERBY-102:
-----------------------------------------

Clobs can be as large as upto 2GB. So,  even if this limit is relaxed, passing 
a large clob constant could still hit the maximum size of the query limit. I am 
not exactly sure if Derby has a limit on maximum size of a query, but it may be 
present. It is also inefficient to insert large data using character constants. 
Are there any problems using PreparedStatements and parameters?

If it is required to avoid PreparedStatements, it may be possible to use 
functions to import clob data at runtime. Clob data will have to be placed in 
files and a file name could be passed as an argument to this import function.
