NHibernate Oracle存储过程问题

Question

------使用VS2008、ASP.Net与C#、Oracle、NHibernate---- 我已经测试了我的存储过程。它可以工作，但不适用于 NHibernate。以下是代码：

过程：

create or replace procedure ThanaDelete (id number) as
begin
 delete from thana_tbl where thana_code = id;
end

映射文件：

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="DataTransfer" namespace="DataTransfer">
  <class name="DataTransfer.Models.Thana, DataTransfer" table="THANA_TBL">
    <id name="THANA_CODE" column="THANA_CODE" type="Int32" unsaved-value="0">
      <generator class="native">
        <param name="sequence">
          SEQ_TEST
        </param>
      </generator>
    </id>
    <property name="THANA_NAME" column="THANA_NAME" type="string" not-null="false"/>
    <property name="DISTRICT_CODE" column="DISTRICT_CODE" type="Int32" not-null="false"/>
    <property name="USER_ID" column="USER_ID" type="string" not-null="false"/>
    <property name="TRANSACTION_DATE" column="TRANSACTION_DATE" type="Date" not-null="false"/>
    <property name="TRANSACTION_TIME" column="TRANSACTION_TIME" type="string" not-null="false"/>

    <sql-delete>exec THANADELETE ? </sql-delete>
  </class>
</hibernate-mapping>

错误：

Message: could not delete: [DataTransfer.Models.Thana#10][SQL: exec THANADELETE ?]
Source: NHibernate
Inner Exception
    System.Data.OracleClient.OracleException
    Message: ORA-00900: invalid SQL statement

Answer 1

我刚刚有一个带有 sql 查询的 ORA-00900。重写你的 SQL 可能

begin exec THANADELETE ?; end;

会解决问题

Answer 2

尝试使用 CALL 而不是 EXEC。

这些测试都使用CALL。
