Microsoft SQL Server的JPA存儲過程com.microsoft.sqlserver.jdbc.SQLServerException：附近有語法錯誤 '{'

Question

我有一個Microsoft SQL Server TSQL存儲過程

SET ANSI_NULLS ON 
GO 
SET QUOTED_IDENTIFIER ON 
GO 
CREATE PROCEDURE [dbo].[sp_get_latest_ids] 
@tblNm VARCHAR(50), 
@ver VARCHAR(50) 
AS 
BEGIN 
DECLARE @stmt VARCHAR(100) 
SET @stmt = 'SELECT id FROM CHANGETABLE(CHANGES [DatabaseName].[dbo].[' + 
@tblNm + '], ' + @ver + ') as c;'; 
EXEC (@stmt) 
END 
GO 

該SP是工作，我所看到的行返回當我運行它像

exec [dbo].[sp_get_latest_ids] @tblNm = 'Reports', @ver = '22379091' 

現在，我想在我的DAO類中使用這個存儲過程使用JPA作爲StoredProcedureQuery

String selectStatement = "EXEC [dbo].[sp_get_latest_ids] @tblNm = 'Reports', @ver = '" + lastVer.toString() + "'"; 
System.out.println(selectStatement); 
StoredProcedureQuery q = em.createStoredProcedureQuery(selectStatement); 
q.setMaxResults(100); 

boolean isResultSet = q.execute(); // returns true when we have a result set from the proc 
//List<Integer> reportIds2 = q.getResultList(); 

這不起作用，我得到一個如下所示的堆棧跟蹤。需要關於如何解決此問題的輸入，因爲'}'不在我的存儲過程代碼中的任何位置。謝謝。

EXEC [dbo].[sp_get_latest_changetable_ids] @tblNm = 'Reports', @ver = '22379091'

Answer 1

在 http://docs.oracle.com/javaee/7/api/javax/persistence/EntityManager.html 的參數createStoredProcedureQuery基礎上的文檔應該是存儲過程的名稱，而不是執行查詢的聲明。嘗試：

StoredProcedureQuery q = em.createStoredProcedureQuery("sp_get_latest_ids"); 

然後綁定你tblNm和版本使用的setParameter（...）所產生的存儲過程的查詢方法的參數。

關於「{」 - 我的猜測是q.execute()正在構建具有該字符的查詢，但由於您的存儲過程「名稱」無效，所以在字符後出現語法錯誤。
