Oracle hibernate ORA-01461 CLOB

问题

//hi all. my problem is that i cannot write big date in clob field. curentli i can write string not greater than 4000 length. can you explain me please why i cannot write clob to clob field. im using:

Oracle Database 11g Enterprise Edition Release 11.2.0.1.0
List item hibernate 4.2.6.Final
List item ojdbc 11.1.0.7.0

My entety is:

@Entity
@Table(....)
public class UiViewSettings implements java.io.Serializable {

    private Integer id;
    private String viewName;
    private String userName;
    private Clob data;
        ....
    @Column(name = "VIEW_DATA", nullable = false)
    public Clob getData() {
        return this.data;
    }
        ....
}

my code of updating entety :

UiViewSettings viewSettings = new UiViewSettings();
Clob createClob;
//creatind clob
viewSettings.setData(createClob);
session.update(viewSettings);

i tried create Clob several ways:

createClob = new SerialClob(xml.toCharArray());

and

connection = DriverManager.getConnection(...);
createClob = ((OracleConnection)connection).createClob();
createClob.setString(1, xml);

both ways throws exception :

EDIT

table is

this code executes fine in SQL Developer

DECLARE
 REALLYBIGTEXTSTRING CLOB := '123';
 i int;
BEGIN

    WHILE LENGTH(REALLYBIGTEXTSTRING) <= 90000 LOOP
        REALLYBIGTEXTSTRING := REALLYBIGTEXTSTRING || '000000000000000000000000000000000';
    END LOOP;
    DBms_output.put_line('I have started inputting your clob: '|| length(REALLYBIGTEXTSTRING)); 
   INSERT INTO UI_VIEW_SETTINGS(view_id , view_name ,user_name, view_data) VALUES(0, 'test', 'test', REALLYBIGTEXTSTRING);
    DBms_output.put_line('I have finished inputting your clob: '|| length(REALLYBIGTEXTSTRING)); 
end ;

回答1:

Try to add the @LOB(type = LobType.CLOB) annotation on top of your data accessor method:

@Column(name = "VIEW_DATA", nullable = false)
@LOB(type = LobType.CLOB)
public Clob getData() {
    return this.data;
}

回答2:

This is limitation in oracle driver. The max length is defined as 4000 in the driver code. I've tried many possible ways but in vein. Surprisingly ,this works with ojbc6 driver.
