从JDBC调用Sqlserver存储过程，Java

Question

我可以从蟾蜍sql服务器运行此查询。

exec msp_FormBsBa_yeni 0,'20150101','20150131',5000,0,2,0,null,1,null,0 

从我的应用程序在java中，它产生错误，因为语句没有返回结果集。我尝试了很多东西，但我无法解决它。感谢您的帮助。

// Connection,Resultset ve PrepStatement Declaration 
    Connection connection = null; 
    PreparedStatement pstmt = null; 
    ResultSet rsa = null; 
    List<EntCari> listrows = new ArrayList<EntCari>(); 

    try { 
     connection = ConnectionFactory.getConnection(); 

     CallableStatement callableStatement = connection 
       .prepareCall("{call msp_FormBsBa_yeni(0,N'20150101',N'20150131',5000,0,2,0,null,1,null,0)}"); 

     rsa = callableStatement.executeQuery(); 

     // 2:resultset check 
     if (!rsa.next()) { 
      System.out.println("no data"); 
     } else { 
      do { 
       // System.out.println("data exists"); 
       // Statements 
       EntCari row = new EntCari(); 
       row.setMusteriadi(rsa.getString("Unvan"));// rsa.getxxx("column") 
       listrows.add(row); 

      } while (rsa.next()); 
     } 

     // 2--- 

    } catch (SQLException e) { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } finally { 
     DbUtil.close(rsa); 
     DbUtil.close(pstmt); 
     DbUtil.close(connection); 
    } 

蟾蜍sql server的结果如下。

Unvan | Ulkesi | VergiKimlikNo | TCKimlikNo | BelgeSayisi | Toplam | CariKod

customer a | 052 | 19697583840 | 1 | 2323,00 | HT00084

customer b | 052 | | 2 | 2111,00 | HT01022

存储过程是像下面（部分SP的，它是长）

/****** Object: Procedure [dbo].[msp_FormBsBa_yeni] Script Date: 18.04.2015 13:43:44 ******/

，这是将错误信息

Answer 1

下面是实现这两种方式..

String SPsql = "EXEC msp_FormBsBa_yeni ?,?,?"; // for stored proc taking 3 params 
Connection con = SmartPoolFactory.getConnection(); 
PreparedStatement ps = con.prepareStatement(SPsql); 
ps.setEscapeProcessing(true); 
ps.setQueryTimeout(<timeout value>); 
ps.setString(1, "val"); 
ps.setString(2, "val"; 
ps.setString(3, "val"); 
ResultSet rs = ps.executeQuery(); 

或通过使用JDBC景观语法

CallableStatement cStmt = conn.prepareCall("{call msp_FormBsBa_yeni (?, ?, ?) }"); 
cStmt.setString(1, "val"); 
cStmt.setString(2, "val"); 
cStmt.setString(3, "val"); 
cStmt.registerOutParameter(4, Types.INTEGER); // register the output params 
cStmt.registerOutParameter("inOutParam", Types.INTEGER); // or by param name 

以了解详情this和this

我希望这可以帮助。

您不能在返回游标/ ResultSet的Transact-SQL CallableStatement上调用executeQuery()。调用该程序的正确方法是这样的：

// You should really use bind variables here... 
CallableStatement call = connection 
    .prepareCall("{call msp_FormBsBa_yeni(?, ?, ?, ...)}"); 
call.setInt(1, ...); 
call.setString(2, ...); 

// This returns true if there are any remaining ResultSets to fetch 
if (call.execute()) { 
    do { 
     try (ResultSet rs = call.getResultSet()) { 
      // Consume the result set here... 
     } 
    } 

    // Move on to the next result set, if any 
    while (call.getMoreResults()); 
} 

如果你想成为完全通用的，你还必须检查Statement.getUpdateCount()，万一有使用结果集，在过程交织更新计数。

当我在数据库客户端（例如SQL Server Management Studio）中执行查询时，返回一个表。

我的存储过程很长，有一些插入和更新语句。如果存储过程在最终选择之前执行任何插入或更新，则JDBC（SQL Server驱动程序）与行计数混淆（并且将抛出语句未返回结果集的异常）。幸运的是，修复非常简单：我只需在存储过程开始时添加SET NOCOUNT ON。所以，我的代码是这样：

CREATE PROCEDURE dbo.msp_FormBsBa_yeni 
@vFirmaNo as integer, 
@IlkTarih as datetime, 
@SonTarih as datetime, 
@MinTutar as float, 
@Bs_Ba_tip as bit, 
@BirlestimeTuru as tinyint, 
@SonradanMuhasebelesenSeriDahilEdilmesin_fl as bit, 
@SonradanMuhasebelesenSeriStr nvarchar(MAX), 
@Aylik_BsBa_fl as bit, 
@PerakendeCariKodu AS nvarchar(25), 
@EvrakDetayliRapor_fl as bit 
AS 
BEGIN 
    SET NOCOUNT ON
