Oracle hibernate ORA-01461 CLOB
//大家好。 我的问题是我不能在clob字段中写大日期。 curentli我可以写不超过4000长度的字符串。 你能解释我为什么我不能写clob到clob领域。 我正在使用：
- Oracle Database 11g企业版11.2.0.1.0版
- 列表项hibernate 4.2.6.Final
- 列表项ojdbc 11.1.0.7.0
我的目的是：
@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; } .... } 我更新entety的代码：
UiViewSettings viewSettings = new UiViewSettings(); Clob createClob; //creatind clob viewSettings.setData(createClob); session.update(viewSettings);
我试过几种方法创建Clob：
createClob = new SerialClob(xml.toCharArray());
和
connection = DriverManager.getConnection(...); createClob = ((OracleConnection)connection).createClob(); createClob.setString(1, xml);
双向抛出exception：

表是

这段代码在SQL Developer中运行良好
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 ;
尝试在data访问器方法的基础上添加@LOB(type = LobType.CLOB)注释：
@Column(name = "VIEW_DATA", nullable = false) @LOB(type = LobType.CLOB) public Clob getData() { return this.data; }
这是oracle驱动程序的限制。 最大长度在驱动程序代码中定义为4000。 我已经尝试了许多可能的方法，但是在静脉中。 令人惊讶的是，这适用于ojbc6驱动程序。
