Łatwo to zrobić z anonimową blokadą. Musimy użyć pętli, ponieważ 32K to największy łańcuch, jakiego możemy użyć w PL/SQL. To działało na Oracle 11g; w przypadku bardzo starych wersji bazy danych należy zamiast tego użyć funkcji DBMS_LOB
SQL> create table t1
2 (id number
3 , large_text clob)
4 /
Table created.
SQL>
SQL> declare
2 c clob;
3 begin
4 for i in 1..30
5 loop
6 c := c||rpad('a', 32767, 'a');
7 end loop;
8 insert into t1 values
9 (myseq.nextval
10 , c)
11 ;
12 end;
