 
Most of the LOB functions take an 
errorp
 argument, which is a boolean controlling what happens if an error occurs inside an OCI function. If 
errorp
 is true, an error is signaled. If 
errorp
 is false, the function returns an error object (of type 
sql-database-error
).
All the LOB functions signal an error if the 
lob-locator
 argument given is not a LOB locator object as returned by 
select
 or 
query
.
Many of the functions basically perform a call to the underlying OCI function. When the match is direct, this is mentioned in the LispWorks Reference Manual .
