“使用NHibernate + Npgsql进行批量操作时，”ON“处或附近的语法错误

Question

我正在尝试使用NHibernate命名参数执行参数化的“upsert”查询，但我得到了一个异常。语法似乎是正确的，但它仍在抛出：

据我所知，根据PostgreSQL文档，语法是正确的：https://www.postgresql.org/docs/9.5/static/sql-insert.html

查询

insert into session (session_expiry,
    session_last_page,
    session_fbr_lh_state,
    session_user_id,
    session_user_guid,
    session_user_name,
    session_user_fname,
    session_image_url,
    session_user_balance,
    session_user_url_profile,
    session_user_cloud_name,
    session_last_qty,
    session_email,
    session_utm_source,
    session_utm_campaign,
    session_utm_medium,
    session_user_agent,
    session_guid) VALUES (
    :session_expiry,
    :session_last_page,
    :session_fbr_lh_state,
    :session_user_id,
    :session_user_guid,
    :session_user_name,
    :session_user_fname,
    :session_image_url,
    :session_user_balance,
    :session_user_url_profile,
    :session_user_cloud_name,
    :session_last_qty,
    :session_email,
    :session_utm_source,
    :session_utm_campaign,
    :session_utm_medium,
    :session_user_agent,
    :session_guid ) 
ON CONFLICT DO UPDATE SET session_expiry = :session_expiry,
    session_last_page = :session_last_page,
    session_fbr_lh_state = :session_fbr_lh_state,
    session_user_id = :session_user_id,
    session_user_guid = :session_user_guid,
    session_user_name = :session_user_name,
    session_user_fname = :session_user_fname,
    session_image_url = :session_image_url,
    session_user_balance = :session_user_balance,
    session_user_url_profile = :session_user_url_profile,
    session_user_cloud_name = :session_user_cloud_name,
    session_last_qty = :session_last_qty,
    session_email = :session_email,
    session_utm_source = :session_utm_source,
    session_utm_campaign = :session_utm_campaign,
    session_utm_medium = :session_utm_medium,
    session_user_agent = :session_user_agent

我如何填充参数（在C＃中）

dbModel.CreateSQLQuery(SESSION_UPSERT)
    .SetParameter("session_guid", data.SessionId)
    .SetParameter("session_expiry", data.SessionExpiration)
    .SetParameter("session_last_page", data.SessionLastPage)
    .SetParameter("session_fbr_lh_state", data.SessionFbrLhState)
    .SetParameter("session_user_id", data.SessionUserId)
    .SetParameter("session_user_guid", data.SessionUserGuid)
    .SetParameter("session_user_name", data.SessionUserName)
    .SetParameter("session_user_fname", data.SessionUserFname)
    .SetParameter("session_image_url", data.SessionUserImageurl)
    .SetParameter("session_user_balance", data.SessionUserBalance)
    .SetParameter("session_user_url_profile", data.SessionUserUrlProfile)
    .SetParameter("session_user_cloud_name", data.SessionUserReferralCloudName)
    .SetParameter("session_last_qty", data.SessionLastQty)
    .SetParameter("session_email", data.SessionEmail)
    .SetParameter("session_utm_source", data.SessionUtmSource)
    .SetParameter("session_utm_campaign", data.SessionUtmCampaign)
    .SetParameter("session_utm_medium", data.SessionUtmMedium)
    .SetParameter("session_user_agent", data.SessionUserAgent)
    .ExecuteUpdate();

我回答了自己的问题。不得不更新到PostgreSQL v9.5。卫生署！
