Microsoft SQL Server的JPA存储过程com.microsoft.sqlserver.jdbc.SQLServerException：附近有语法错误 '{'

Question

我有一个Microsoft SQL Server TSQL存储过程

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 

该SP是工作，我所看到的行返回当我运行它像

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

现在，我想在我的DAO类中使用这个存储过程使用JPA作为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(); 

这不起作用，我得到一个如下所示的堆栈跟踪。需要关于如何解决此问题的输入，因为'}'不在我的存储过程代码中的任何位置。谢谢。

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 的参数createStoredProcedureQuery基础上的文档应该是存储过程的名称，而不是执行查询的声明。尝试：

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

然后绑定你tblNm和版本使用的setParameter（...）所产生的存储过程的查询方法的参数。

关于“{” - 我的猜测是q.execute()正在构建具有该字符的查询，但由于您的存储过程“名称”无效，所以在字符后出现语法错误。
