【问题描述】：
我有一个 DataSource，它将 Odata 传递给 Teiid，然后传递给 Oracle。但是，当我尝试从 Kendo DataSource 传递一个日期时，Oracle 感到窒息。我认为这是因为 Oracle 无法识别其发送格式的日期字符串 - 例如，2014-07-01T05:00:00.000Z - 是有效的。这是我得到的错误：
avax.persistence.RollbackException: Exception [EclipseLink-4002] (Eclipse Persistence Services - 2.4.1.v20121003-ad44345): org.eclipse.persistence.exceptions.DatabaseException
Internal Exception: org.teiid.jdbc.TeiidSQLException: TEIID30504 JTRAC_DEV_ENV: 1843 TEIID11013:TEIID11004 Error executing statement(s): [Prepared Values: ['2014-07-01T05:00:00.000Z', 700281, 700280] SQL: UPDATE "JTRAC"."MAPPED_HISTORY" SET "TIME_STAMP" = ? WHERE "JTRAC"."MAPPED_HISTORY"."HISTORY_ID" = ? AND "JTRAC"."MAPPED_HISTORY"."ITEM_ID" = ?]
Error Code: 1843
Call: UPDATE "JTRAC.MAPPED_HISTORY" SET "TIME_STAMP" = ? WHERE ((("HISTORY_ID" = ?) AND ("ITEM_ID" = ?)) AND ("TEIID_MULTI_DATA_SOURCE_COLUMN" = ?))
bind => [2014-07-01T05:00:00.000Z, 700281, 700280, JTRAC_DEV_ENV]
如何将时间戳更改为可以使用的内容？我已经尝试使用 parameterMap （似乎还没有在那个阶段转换它 - 仍然是相当正常的时间格式），requestStart（我似乎无法访问数据以篡改它）和解析（isn' t 以我期望的方式工作）。作为记录，另一端有一个 INSTEAD OF Oracle 触发器，因为最终我正在更新一个视图。想法？
这是我正在使用的触发器：
create or replace
trigger update_mapped_history
INSTEAD OF UPDATE ON mapped_history
FOR EACH ROW
DECLARE
new_status_id number;
new_assigned_to number;
new_logged_by number;
new_timestamp timestamp;
cmmd VARCHAR2(100);
BEGIN
cmmd:='alter session set NLS_TIMESTAMP_FORMAT=''YYYY-MM-DD"T"HH:MI:SS.FF"Z"''';
EXECUTE IMMEDIATE cmmd;
SELECT status_id INTO new_status_id FROM status_int_mapping WHERE status_label=:NEW.status AND space_id = (select i.space_id from items i where i.id = :OLD.item_id);
SELECT id INTO new_assigned_to FROM users WHERE login_name = :NEW.assigned_to;
SELECT id INTO new_logged_by FROM users WHERE login_name = :NEW.logged_by;
select FROM_TZ(TO_TIMESTAMP(:NEW.time_stamp, 'YYYY-MM-DD"T"HH:MI:SS.FF"Z"'),'UTC') at time zone 'US/Central' into new_timestamp from dual;
UPDATE history SET
logged_by = new_logged_by,
status = new_status_id,
assigned_to = new_assigned_to,
jt_comment = :NEW.jt_comment,
time_stamp = new_timestamp
WHERE id=:OLD.history_id;
END;
这是我的所有荣耀的代码。
