SSIS/DTSX: Set ‘IsSorted’ property for the source of MergeJoin

Categories: Database; Tagged with: ; @ December 13th, 2012 15:31

“Merge Join” is a partially blocking component and it requires the source is sorted.

There are two ways to get the source :

1. Use “Sort” component.  — Sort is a full blocking component.

2. Sort the source in SQL and mark “IsSorted”

Because Sort is a full blocking component,  So I think the second one will get better performance.


I keep the two source sorted, and got one Error:
The IsSorted property must be set to True on both sources of this transformation.

I can not find this property in the properties or Editor, that’s why I hate SSIS sometimes.

At last I got it from “Advanced Editor…”:


and that’s not enough, we need to specify the SortKeyPosition:

Modify SSIS package’s ProtectionLevel and password using C#

Modify SSIS DTSx package production level and password.


It’s terrible to open and edit each package, luckily, we got the interface: Microsoft.SqlServer.Dts.Runtime. (How to add the lib)


using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.SqlServer.Dts.Runtime;

    class DtsUtils
         * Change DTSX package password
        public static void changePassword(String pkgLocation, String oldPassword, DTSProtectionLevel dtsPrdLevel, String newPassword)
            Application app = new Application();

            if (oldPassword != null && oldPassword.Trim() != "")
                app.PackagePassword = oldPassword;

            Package pkg = app.LoadPackage(pkgLocation, null);

            // Modify the password
            pkg.ProtectionLevel = dtsPrdLevel;
            pkg.PackagePassword = newPassword;

            // Save dts pacakge
            app.SaveToXml(pkgLocation, pkg, null);

Get source code from GitHub:

Besides password, there’re many interfaces, like logging, Connections, variables,.


1. SaveToXml:

SSIS package Transaction Error: 0x8004D01B The Transaction Manager is not available

Categories: Database; Tagged with: ; @ December 9th, 2012 11:43


Error: 0xC001401A at Transaction: The SSIS Runtime has failed 
to start the distributed transaction due to error 0x8004D01B 
"The Transaction Manager is not available.". The DTC transaction 
failed to start. This could occur because the MSDTC Service is not running
make sure the service called”Distributed Transaction Coordinator” is running.

在SSIS/DTSx中使用事务管理 Using Transaction in SSIS DTSx package

Categories: Database; Tagged with: ; @ December 9th, 2012 11:32




需求:  DataFlow转移数据时非0即1, 一旦遇到失败, 回滚到操作前的状态.

解决: 使用Transaction.



表1 Source: tbUser: userID, userName, emai, age(varchar)

表2, Destination: 结构与表1相似, 但age 类型为 int.

(用for loop insert一堆数据:

DECLARE @i int
SET @i = 0
WHILE @i < 1000000
    SET @i = @i + 1
    INSERT INTO guoliangDB.dbo.tbUser (userName, email) values (‘name’ + CAST(@i as varchar(8)), ’[email protected]’ + CAST(@i as varchar(8)))



update tbUser set age = ‘fakeage’ where userID = 980000;






运行结束, 错误信息:

OnError,,9/12/2012 11:17:58 AM,9/12/2012 11:17:58 AM,-1071636471,0x,SSIS Error Code DTS_E_OLEDBERROR.  An OLE DB error has occurred. Error code: 0x80004005.
An OLE DB record is available.  Source: “Microsoft SQL Server Native Client 10.0”  Hresult: 0x80004005  Description: “Invalid character value for cast specification”.

OnError,,9/12/2012 11:17:58 AM,9/12/2012 11:17:58 AM,-1071607780,0x,There was an error with input column “age” (54) on input “OLE DB Destination Input” (38). The column status returned was: “The value could not be converted because of a potential loss of data.”.

此时Select Destination的数量为: 979998. 剩余的数据不会再被导入.

修改Dataflow transaction属性为: required

在遇到错误之后, Select destination数量, 逐渐减少, 直至rollback到0.

结论: 如需要事务支持, require transaction.

SSIS Designer(Visual Studio 2005) cannot open package: Exception from HRESULT: 0x8007007E (System.Windows.Forms)

Categories: Database; Tagged with: ; @ December 8th, 2012 17:31

I try to apply SQL Server 2005 in my PC(Win 7 64bits), failed, After that, when I try to open SSIS package in BIDS, I got this Error every time:

TITLE: Microsoft Visual Studio

An error prevented the view from loading.
The specified module could not be found. (Exception from HRESULT: 0x8007007E) (System.Windows.Forms)

—————————— BUTTONS: OK ——————————


It’s kind of ridiculous. because I need to finish my DTSx package design,  so I re-install SQL Server sp1. but seems no change.

Then I got this link:

2008 SSIS Designer stops working after installing VS11 Dev Preview

the chosen answer seems not for me, and I got the solution from one of the reply:

I solved the problem by deleting the whole folder “C:\Program Files (x86)\Common Files\microsoft shared\MSDesigners8“, and copying it from a machine that was working. Not the smoothest solution, I know, but it did work!
