返り値: clob_handleにより指定したCLOBを含む文字列。
fbsql_read_clob()
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
fbsql_set_lob_mode()
so the fetch functions will return handles to BLOB and CLOB
data. If a handle is fetched a user must call
fbsql_read_clob()
to get the actual CLOB data from the database.
