Microsoft SQL Server JPA 存储过程 com.microsoft.sqlserver.jdbc.SQLServerException：“{”附近的语法不正确答案

【问题描述】：

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

这个 SP 正在工作，当我运行它时我看到返回的行

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

现在我正在尝试在我的 DAO 类中将此存储过程与 JPA 一起用作 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，我得到如下所示的堆栈跟踪。此时需要输入有关如何修复的信息，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'

【问题讨论】：

不应该createStoredProcedureQuery只取存储过程的name吗？很可能是转换成JDBC调用转义，触发语法错误。

标签： java sql-server jpa stored-procedures jdbc

【解决方案1】：

基于文档 http://docs.oracle.com/javaee/7/api/javax/persistence/EntityManager.html createStoredProcedureQuery 的参数应该是存储过程的名称，而不是执行查询的语句。试试：

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

然后使用生成的存储过程查询的 setParameter(...) 方法绑定您的 tblNm 和 ver 参数。

关于“{” - 我的猜测是q.execute() 正在构建一个具有该字符的查询，但由于您的存储过程“名称”无效，因此您在该字符后出现语法错误。
