How To Enable Or Disable A Task Programmatically Using Script Task
Mar 6, 2006
I have made one package which extracts data from the source does transformation and submits the data to destination. Subsequently it also updates the required control files.
Now I want to add a functionality :
If the package is executed again it should check the status of previous execution in control file if success mark all tasks disable and stop
if failure mark all tasks at enable and start extracting data and continue further with execution.
I was able to attain similar functionality in SQL Server 2000 using activeX script. What code do I need to write as a part of Script Task in order to attain above functionality.
ESQL1 will get max(id) from table and then based on the ID the remaining needs to be work.
Ex: If the ID=AUS-Sdy-1 then ESQL2 will update the tbl1 and return one IDkey based on this return key the ESQL3 will update a tbl2. ----------*( i want to disable ESQL4) else If the ID=AUS-Sdy-2 then ESQL3 will update the tbl1 and return one IDkey based on this return key the ESQL4 will update a tbl2. ----------- *(i want to disable ESQL2)
I have a package comprising a number of Data Flow Task steps, to import various tables of data from some Access databases into SQL Server. The name of some of these Access databases will change depending on the date, e.g. last year's data is currently in a database called "2005data.mdb". At year end this will be superseded by "2006data.mdb". The Access databases are within a 3rd party system so I have no control over the file names.
I have a Script Task that checks the current date, and changes the name of an Access database in the connection string to reflect last year's date. But to complicate matters, last year's file might not exist.
So the Script Task checks whether the file name exists. If not, I would like to disable the Task that uses this connection. But how do I reference a task within the package that contains my Script Task, by name, to set the Disabled attribute to true?
I want to do something like CurrentPackage.Tasks("MyDataFlowTask").Disabled = True.
I would also welcome alternative suggestions for how to achieve this.
OK. I give up and need help. Hopefully it's something minor ...
I have a dataflow which returns email addresses to a recordset.
I pass this recordset into a ForEachLoop configuring the enumerator as (Foreach ADO Enumerator). I also map the email address as a variable with index 0.
I then have a Execute SQL task which receives this email address as a varchar variable (parameter 0) which I then use in my SQL command to limit the rows returned. I have commented out the where clause and returned all rows regardless of email address to try to troubleshoot this problem. In either event, I then use a resultset to store the query result of type object and result name 0.
I then pass this resultset into a script variable to start parsing the sql rows returned as type object. ( I assume this is the correct way to do this from other prior posts ...).
The script appears to throw an exception at the following line. I assume it's because I'm either not passing in the values properly or the query doesn't return anything. However, I am certain the query works as it executes just fine at the command prompt.
My intent is to email the query results to each email address with the following type of data by passing the parsed data from the script to a send mail task. Email works fine and sends out messages but the content is empty. I pass the parsed data as string values to the messagesource and define the messagesourcetype as a variable in the mail task.

Does anyone have any idea what I might be doing wrong?
Is it possible to add a Fuzzy Grouping Transformation in a Data flow task by Programmatically ? If it possible, what is the C# or VB .net code for that ?
I am making some changes to a tracking SP that I'm using in about 100 SSIS packages. I don't want to go into each package and add the additional parameter (A "?") and map a variable to some ordinal position. I'd like to do this programmatically.
I have some expirence in validing variables and manipulating connection objects in packages though a utility that I wrote. However, I cannot find any guidance on How to create/edit Execute SQL Tasks via code in the package. I would like to do something like this..
Code Snippet private Microsoft.SqlServer.Dts.Runtime.Application app = new Microsoft.SqlServer.Dts.Runtime.Application(); Package p = app.LoadPackage(DTSPackage, null); p.Executables["My Execute SQL Task"]
However, the Executables returns an Executable object that is a DtsObject. Do I have to add a reference to the task and cast this executable to that type? Any help is appreciated.
I am having trouble with using disable property in the expression for data flow task. Here is the issue as explained below-
lets say i have 3 tables TableA, TableB, TableC from which i need to export data. So i create a table (TableList) where I save these table names and a unique id to these tables. e.g.
in the ssis package select these tableNames & Ids from tableList in Execute SQL Task. And assign the result set to a variable object (@TableList.
Then i use For Each Loop Container (For Each ADO Enumerator) , to loop through these tablesnames & iDs
Inside this loop container, i define three data flow tasks one for each table. So i have DataFlowTaskA (For TableA), DataFlowTaskB(For TableB), DataFlowTaskC (For TableC).
Now for a given table selected in the iteration, only the corresponding DataFlow Task should be exeuted. e.g. For the 1st iteration, if TableA is selected then only DataFlowTaskA should be executed and DataFlowTaskB& C should be skipped.
In order to achieve this, I am using a 3 variable @FlagA, @FlagB, @FlagC (type Boolean) one for each Table. and use the value of these flags for the "Disable" property of the data flow task (so @FlagA will be used for Disable property in the Expression for Data FlowTaskA, and so on..)
SotThe First Step inside the Loop, I use Script Task. (Input for the script task: read variable is @TableID and Read/Write varaibles are these 3 flags)
In this script task, I initialize these flags to true or false appropriately. So this is what i do
If (Dts.Variables("TableID").Value.ToString = "1") Then Dts.Variables("@FlagA").Value = False Else Dts.Variables("@FlagA").Value = True
End If
If (Dts.Variables("TableID").Value.ToString = "2") Then Dts.Variables("@FlagB").Value = False Else Dts.Variables("@FlagB").Value = True
End If
So in the 1st iteration, (if TableA comes) @FlagA=False and B&C will be True. So the Disable property for DataFlowTask will be set false and for others it will be set to True. Thus, only DataFlowTaskA will be executed.
And this action should be repeated for each input table. this is the logic.
However only for the 1st iteration(say TableA is selected) it behaves as above. i.e. DataFlowTaskA is executed and DataFlowTaskB & C are skipped. But in the 2nd iteration(say TableB is selected) , it again executes DataFlowTaskA and doesnt exeute B & C (where it should have executed B & skipped A&C).
I do set daelay validation to true for all these but it still it doesnt working as expected. Even I checked the values for all the flags for each iteration and they seem to get the correct values. But somehow Diable propery in the expression not behaving as it should.
Am i missing anything. Do i need to set any other property to make this work.
I am executing a child package programmatically and want few lines of code to detect cause of the failure on the fly. One way will be to run the child package through dtexec command uility. But on the fly i will be assigning few values in Parent package variable to the child variables and finally run the child package. Since we cannot apply expressions or use precendence constraints in place, It seems that we are left with only choice to programmatically detect errors in tasks. In DTS, it was achieved this way:

I am developing tools for automatic creation of data warehouse tables, cubes and SSIS packages. Generating the SSIS Data Flows works very well using the SSIS components for OLE DB Source, Derived Column, Lookup and OLE DB Destination.
However for some of the advanced functionality I need to use Script Component. I have managed to add it in the Data Flow with all inputs and outputs, but how do I populate it with my code? I've seen there is a component property called "SourceCode" and one called "BinaryCode". The "SourceCode" contains the code, but also some extra metadata.
Questions:
Do you know if there is any programmatic support to generate the Source Code property with the metadata necessary?
Do you know how to compile the Source Code and generate the property BinaryCode?
Has anyone done this? I can't find anything in the documentation that describes this. The closest I get is to the InnerObject property of the TaskHost class. There is an example of programming a bulk insert task. But I can't find anything on programmatically setting the column mappings (source to dest) of a simple data flow task. Any help is appreciated!
Hi, is there a way how to enable / disable logging on web merge synchronization into the file websync.log? The file exists in the ISAPI folder, on some machines there are some messages, on others there is nothing. There are Timeout messages on the client during synchronization and we need to find where is the problem, if it is on the server side or if it is a network error or something else. Thanks, Pavel
Is there any procedure or option to disable and enable constraints on database.the problem is we are having lot master and child tables. when i am trying to move the entire data from original db to another same db, there i am getting constraints problem. child tables are not accepting data with out loading the master tables.
is there any to disable and enable constraints? please give me reply asap
Is there a chance to change the case sensitivity option for a running instance of sql server?
I know, during the install process, i can activate the case sensitivity. But can I change this option on an already installed server (to case sensitiv or back)?
Is there a way to turn on/off a given logger dynamically across the board, and still enable the logging of task specific events, like "ExecuteSQLExecutingQuery" from the ExecuteSQL task or "WMIDataReaderOperation" from the WMI Data Reader task?
The use case is one where multiple loggers are defined in a package (custom and stock) and I'd like to toggle the execution tracing on a per logger basis.
I realize "logger toggling" can be done programmatically, but I'm wondering if that's the only way to accomplish the objective.
I am a beginner in SQL Server Reporting Services. My report has three parameters; all with the same characteristics (combobox (multiple values, datatype: String, Available values: from query, default value:null).
When i am in the Preview Tab of the Report, the combo box of the first parameter is enabled, the combo box of the second parameter is disabled.
Once i select a value for the first parameter, the combo box of the second parameter becomes enabled.
I would like to select a value for the the second parameter in spite i did not select a value for the first parameter. I do not find a solution in the properties of the parameters.
Is it possible to run a trigger whenever a SQL user is disabled or enabled? From what I've seen of various sysusers and syslogins tables there isn't a column that represents enabled or disabled.
I have transaction replication setup on two SQL7 boxes and a nightly job runs a procedure that need to alter a table and disable a trigger. Since replication has been set up the disable doesn't work. Any way around this.
the disable trigger will be enable again.Because I already disable the trigger on last month, but when I check through the database, it enable again.I understand that, when we restore the database, all the trigger will be enable.How about SQL Cluster? will it enable the trigger??
I currently have serverA importing data from an AS400 oledb connection and serverB on hot-standby as a mirror. The data import is being performed via an SSIS scheduled job.
I've yet to implement any solution in the following case: If the database on serverA fails, it will failover to the mirror. But the jobs will still be on serverA. Ideally, I'm assuming the jobs should not run on serverB since it will be attempting to update the mirrored database. So, I am wondering if both servers can have identical copies of SSIS packages and jobs and simply (?) enable or disable them based on which server will be hosting the principal database.
Is there any solution where the jobs can automatically be disabled on the server with the mirrored database and enabled on the principal database depending on its status?
I have a parameter for each field that lets me know if a field can be sorted or not. What I want to be able to do is turn on or off interactive sorting for that column based on that parameters value.
In the dialog you have a check box that says enable interactive sorting. When that is clicked it appears that you get the two arrows no matter what you put in the expression.
I have tried
=IIF(allowSorting,Fields!myColumn.Value,"")
and
=IIF(allowSorting,Fields!myColumn.Value,Nothing)
but both result in the arrows still being there, just the sort doesn't work.
Is it possible to put an expression on the sort arrows appearing at all?
I'm using SSIS in Visual Studio 2012. My Execute SQL Task calls a Stored Procedure where I have a TRY-CATCH. Last week there was a problem and the CATCH was executed and logged an error to my error table, but for some reason the Execute SQL Task didn't fail. Is there a setting to make the Execute SQL Task fail when an SP encounters a failure?
I am trying to create a simple BI Application for SSIS. In Visual Studio 2005 I just get a Data Flow Task from the toolbar and add it to the project. When I double click it I get the following error:
The task with the name "Data Flow Task" and the creation name "DTS.Pipeline.1" is not registered for use on this computer.
Then when I try to delete it it gives this other error:
Cannot remove the specified item because it was not found in the specified Collection.
I am creating this application in an administrator account in this computer, so I doubt the problem is related to permissions. I am running SQL Server 2005 and Visual Studio 2005 in WinXP Tablet PC Edition.
Any suggestions why this is happening and how to fix it?
I am using the "Transfer SQL Server Objects Task" to copy some tables from database A to database B including data.
The tables, primary key constraints, Foreign key, data and all transfers nicely except for "DEFAULT CONSTRAINTS" on the tables.
I have failed to find any option in the "Transfer SQL Server Objects Task" task to explicitly say "copy default constraints". So I guess logically it should happen automatically but it doesn't. I hope it is not a bug :-)
