Reads CLOB data from the database.

If a select statement contains BLOB and/or CLOB columns FrontBase will
|
|
return the data directly when data is fetched. This default behavior can
|
|
be changed with <function>fbsql_set_lob_mode</function> so the fetch
|
|
functions will return handles to BLOB and CLOB data. If a handle is
|
|
fetched a user must call <function>fbsql_read_clob</function> to get the
|
|
actual CLOB data from the database.
