DB2 SQL錯誤：SQLCODE = -117，SQLSTATE = 42802，SQLERRMC = null，DRIVER = 3.68.61

Question

我在使用Java進行開發並將記錄插入DB2數據庫時遇到此問題。

sqlInsert = "INSERT into SI_Orders (SellersNo,OrderDate,ShipDatePlanned," 
      + "Warehouse,OrderType,ShipToName,ShipToAddress1," 
      + "ShipToCity,ShipToProvState,ShipToPostalZip,ShipToCountry" + ") " 
      + "VALUES (?, ?, ?,'01','DO','bob','a','toronto','ON','h0h0h0','CA')"; 

    try { 
     con = dc.getConnection(); 
     con.setAutoCommit(false); 
     db2Stmt = con.prepareStatement(sqlInsert); 

     for (Order order : orderWrapper.orders) { 
      save1 = con.setSavepoint(); 
      db2Stmt.setString(1, order.getOrderId()); 
      db2Stmt.setTimestamp(2, shipStnDateFormat(order.getOrderDate()));    
      db2Stmt.setString(3, null); // PONo 
      /* 
      * db2Stmt.setTimestamp(4, shipStnDateFormat(order.getShipByDate())); 
      */ 
      db2Stmt.executeUpdate();  
      //con.commit(); 
     } // end of enhanced for each block 
    } // end of try block 

    catch (SQLException e1) { 
     e1.printStackTrace(); 
     if (con != null) { 
      try { 
       System.err.print("Transaction is being rolled back."); 
       con.rollback(); 
      } 

      catch (SQLException se) { 
       se.printStackTrace(); 
      } 
     } // end of if(con != null) block 
    } // end of catch block 
    finally { 
     // Clean-up code 
     con.setAutoCommit(true); 

     if (db2Stmt != null) { 
      db2Stmt.close(); 
     } 

     if (con !=null){ 
      con.close(); 
     } 
    } // end of finally block 
} // end of insertDB method 

private Timestamp shipStnDateFormat(String shipByDate) { 
    SimpleDateFormat shipStnDateFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss"); 
    SimpleDateFormat standardDateFormat = new SimpleDateFormat("yyyy-MM-dd"); 
    String parsedFinalFormattedDate = null; 
    Date finalDate = null; 

    if (shipByDate == null) 
     return new java.sql.Timestamp(0); // return a dummy value 

    else { 
     try { 
      Date parsedShipByDate = shipStnDateFormat.parse(shipByDate); // 
      parsedFinalFormattedDate = standardDateFormat.format(parsedShipByDate); // 
      finalDate = standardDateFormat.parse(parsedFinalFormattedDate); // 
     } catch (ParseException e) { 
      e.printStackTrace(); 
     } 

     return new java.sql.Timestamp(finalDate.getTime()); 
    } // end of else statement 
} // end of shipStnDateFormat method` 

我得到這個錯誤... DB2 SQL錯誤：SQLCODE = -117，SQLSTATE = 42802，則sqlerrmc = NULL，DRIVER = 3.6in8.61

很顯然，我就喜歡插入所有三列而不拋出SQL異常。

另外，這裏是我用來創建表的DDL，它顯示每列的數據類型以及是否強制執行NOT NULL約束。

第一列「OrderId」是標識列，所以我沒有爲此發出插入參數。

CREATE TABLE SI_Orders (
OrderId INTEGER NOT NULL generated always as identity (start with 0, 
increment by 1, no cache), 
SellersNo VARCHAR(20) NOT NULL, 
OrderDate Timestamp(0) NOT NULL, 
PONo VARCHAR(20), 
ShipDatePlanned Timestamp(0) NOT NULL, 
CONSTRAINT PK_SI_Orders PRIMARY KEY (OrderId) 
); 

Answer 1

要設置：

db2Stmt.setString(3, null); // PONo 

當你的模型狀態該列：

ShipDatePlanned Timestamp(0) NOT NULL, 

所以將它設置爲NULL是不允許的，更新參數3到非NULL值應該解決這個問題。

Answer 2

要將列添加到查詢你可以這樣做：

sqlInsert = "INSERT into SI_Orders (SellersNo,OrderDate,ShipDatePlanned,PONo," 
     + "Warehouse,OrderType,ShipToName,ShipToAddress1," 
     + "ShipToCity,ShipToProvState,ShipToPostalZip,ShipToCountry" + ") " 
     + "VALUES (?, ?, ?,?,'01','DO','bob','a','toronto','ON','h0h0h0',?)"; 

因此，在隨機位置在字符串中添加一列，並增加了？在VALUES中會添加該列。

該指數？從1開始，僅匹配參數替換的列名稱。

例如：在本示例ShipToCountry將指數5
