申し訳ありませんが、私は Python 3.2 を持っていません。これは Python 2.7 上にあります。
オラクルの場合:
scott@XE_11g> CREATE TABLE t (id NUMBER, c CLOB);
Table created.
scott@XE_11g> INSERT INTO t VALUES (1, 'Happy families are all alike; every unhappy family is unhappy in its own way.');
1 row created.
scott@XE_11g> INSERT INTO t VALUES (2, q'[You don't know about me without you have read a book by the name of The Adventures of Tom Sawyer; but that ain't no matter.]');
1 row created.
scott@XE_11g> COMMIT;
Commit complete.
scott@XE_11g>
今、Pythonで:
import cx_Oracle
connection = cx_Oracle.connect('scott/tiger@XE')
cursor = connection.cursor()
new_clob = cursor.var(cx_Oracle.CLOB)
new_clob.setvalue(0,'It was a bright cold day in April, and the clocks were striking thirteen. ')
key_id = cursor.var(cx_Oracle.NUMBER)
key_id.setvalue(0,2)
cursor.execute("""UPDATE t
SET c = :p_clob
WHERE id = :p_key"""
, p_clob = new_clob
, p_key = key_id
)
connection.commit()
そして、再び Oracle に戻ります。
scott@XE_11g> SELECT c FROM t WHERE id = 2;
C

It was a bright cold day in April, and the clocks were striking thirteen.
