Integration Services SSIS parameters allow you to assign values to properties within packages at the time of package execution. You can create project parameters at the project level and package parameters at the package level.
Project parameters are used to supply any external input the project receives to one or more packages in the project. Package parameters allow you to modify package execution without having to edit and redeploy the package.
You associate a new or an existing parameter with a task property by using the Parameterize dialog box. For more about using the Project. For more information about the Parameterize dialog box, see Parameterize Dialog Box. In general, if you are deploying a package using the package deployment model, you should use configurations instead of parameters.
When you deploy a package that contains parameters using the package deployment model and then execute the package, the parameters are not called during execution.Jobs worksheets for kindergarten
If the package contains package parameters and expressions within the package use the parameters, the resulting values are applied at runtime. If the package contains project parameters, the package execution may fail. For more information, see the following topics. Views Integration Services Catalog. Stored Procedures Integration Services Catalog. Configure Dialog Box. Execute Package Dialog Box. You can assign up to three different types of values to a parameter.
When a package execution is started, a single value is used for the parameter, and the parameter is resolved to its final literal value. You can use a single parameter to assign a value to multiple package properties. A single package property can be assigned a value only from a single parameter.
The execution is an object that represents a single instance of package execution.
When you create an execution, you specify all of the details necessary to run a package such as execution parameter values. You can also modify the parameters values for existing executions. When you explicitly set an execution parameter value, the value is applicable only to that particular instance of execution. The execution value is used instead of a server value or a design value.
If you do not explicitly set an execution value, and a server value has been specified, the server value is used. When a parameter is marked as required, a server value or execution value must be specified for that parameter. Otherwise, the corresponding package does not execute. Although the parameter has a default value at design time, it will never be used once the project is deployed.ODBC Connections - Passing Parameters and Modifying SQL Statements
If a parameter references an environment variable, the literal value from that variable is resolved through the specified environment reference and applied to the parameter. The final literal parameter value that is used for package execution is referred to as the execution parameter value.
You specify the environment reference for an execution by using the Execute dialog box. If a project parameter references an environment variable and the literal value from the variable cannot be resolved at execution, the design value is used. The server value is not used. To view the environment variables that are assigned to parameter values, query the catalog.Does anyone have an example of how to use a SSIS variable in an openquery stmnt.
I am having a hard time finding a way to pass the variable to the openquery. Don't tell me I can't use a variable instead of a static query? What am I doing wrong?Claims of fact value and policy
Thanks, Skip. Can anyone look at the code below and let me know what I am doing wrong. I have the following SQL. How do I do this? I'm posting this because I found this solution after much digging. I'm posting because I spent a lot of time trying to get this to work and also, have seen other posts here that hinted it wasn't doable. Can I determine if a value is numberic then output 'text' else output'some other text'?
I'm trying to do this in a select statement. Otherwise, just get yesterdays data. This works,however it slowed down the query by 12X. I think it may be the use ofa "case" because if I hard code it there isn't a problem.
Anysuggestions for alternatives? I'm working on an SSIS package that uses a vb. Variable "MyXML". I think the problem is that the dataflow XML source has a lock on the variable and so the script task isn't affecting it. Does anyone have any experience with this kind of problem, or know a workaround? The package runs without error, but the actual row does not calculate the running totals.
I suspect that the inserted record is not committed until the package completes and the SQL Task is seeing the previous record as the current. Net for several years. The original process worked, but did not check the creation date of the import file.
I've been asked to add logic that will check that date and verify that it's more recent than a value stored in the database before the import process executes. Here are the task steps. If so, stop execution. Otherwise, proceed to the next step.
Assign that date to a global value FileCreateDate and pass it to the next step.
This works. This is where the process breaks.Newsies cast disney movie
This step depends on 2 variables defined at a global level.Join Stack Overflow to learn, share knowledge, and build your career.

Bryan Bryan Thanks for the try. ConsultingMechanic RPC has to be enabled for the linked server. If that doesn't work, use a script task to the query and execute against the source.
Or better yet, query the source directly. Linked servers aren't built for moving large amounts of data around SSIS is. If I run an SSIS package that does not have a parameter then everything works correctly going through the linked server. Just need to get the same query to accept a parameter.

This article is going to dive into an example that parameterizes the Server Name and Initial Catalog database name in a connection string for packages in a project. The Connection String for a database can be created for an individual package or for a project in Visual Studio. These Connection Managers are available to either just the package or any package in a project. If the connection to the database needs to be used in multiple packages, use the Project Connection Manager.
Figure 1: Connection Manage. Once a connection is created in the Project Connection Manager, it is available to the packages in the project. The connection properties are changed from the Package Connection Manager which can be confusing. Figure 2 shows the prefix project on the connection name in the package DimProduct. A connection DW created just in the package will not have this prefix. Figure 2: Database Connections. The properties available when selecting the connection in the Package Connection Manager can be changed to parameterize the connection string.
The Expression property is going to be used to change the connection string. The entire string can be changed or just parts like Server Name and Initial Catalog database name. Figure 3 shows right-clicking the project ADVDW14 database connection and selecting the Parameterize… submenu, which is a shortcut.Lavoro congiunto in inglese
Figure 3: Parameterize Shortcut. But before we use shortcuts, it is better to learn the areas used by SSIS to complete this parameterization. The first new area is Project Parameters in the Solution Explorer of the project. So, if you use the parameter in more than one package in a project, and the value is changed before executing, then all packages will see and use the new value. Figure 4: Project Parameters. There will be 2 new parameters created: ServerName and DatabaseName. The values used when developing and testing this package will be different than when deployed to production.
To create Project Parameters, just double-click the Project.
There will be a toolbar button available to create new parameters. Figure 5: Add New Parameter. Place the name of the parameter in the name column.
TSQL: Pass parameter to OPENQUERY statement
The Data Type in this case is string. Value is used for initial value. Column Required is used to force a value in the parameter before executing. An error is returned when the Required parameter has no value.
Figure 6: New Project Parameters. To change the connection string to use the project parameters, select the connection in the package Connection Managers, and go to the properties window. If the properties window is not already visible, right-click the connection and select properties. It is convenient to have the properties docked to the right and under the solution explorer.
Figure 7: Expressions Property. Click the ellipse to the right of the Expressions property and the Property Expression Editor window will pop up.
Workaround to Pass Parameter to OpenQuery using Linked Server on SQL Server
Figure 8: Property Expression Editor. One of the available properties is ConnectionString, but this makes you edit the whole string rather than just parts of the string. The property used for changing the database is InitialCatalog. This property can be traced back to the original OBDC driver days, which by the way are making a return.Ken at work.
More actions. But how do I make this last example one with parameters a table that can be used in a Select From blah, blah, blah I finally got all of the tables joined with the calcs in a stored procedure and all without using Row by Row calculations. You guys were right, again.
I owe you. This is part of it and the last piece. You can probably use Insert I know it works with procs, and I think it works with dynamic SQL. Otherwise, you'll have to have the Where clause outside of the OpenQuery statement. I've used OpenDatasource that way, and it works out okay. I use 'Where' statements in OpenQuerys to the database often. Often in the statements I willl going multiple [linked] tables with each having their own 'Where'. It's just the Execute that failed. The error you're getting per a prior post is that it can't open a distributed transaction.

What am I doing wrong here? A marginally more secure way would be to wrap it in something like I blame lack of sufficient sleep. Actually, I was wrong, this wasn't a good point. Since it never actually tries to run that, it's safe. I had to take a few liberties with your example, because there are a few problems with your original presentation: 1 It doesn't include the name of the Linked Server to open the query on 2 OPENQUERY doesn't accept "pieced together" queries, nor does it accept variable names which contain the query.
Ok, I'll admit it, you're right there. But, it is still a good point, security by obscurity being a bad idea and everything. As for the other two points, you'll notice that I said that I've never used OpenQuery, so I was just trying to give a general idea. Question for The Jet. So I have tblCustomers and tblAddresses on the linked server. Is that a valid concern? ALL the data for this query is on the linked server, the only thing that isn't is the parameter I'm passing for what I want to search for, maybe everyone who ever lived on Maple Street or something, or had a phone number Will this query execute on the linked server, and how could I use the query execution plan to help me determine that?
I obviously don't know about query tuning at this point in my learning, so help there is appreciated. The real answer is that you just need to try it out and see what happens with the queries you have, then work through optimizing them as needed. I'm sure there are things you could do to cause a breakdown and horrible performance, but I can't tell you what all those things are.
D0rk Angle. Originally posted by TheJet: well, technically you're still vulnerable to SQL Injection because you're putting the parameter declaration into a string before sending it over. Please tell me more about the injection attack threat.The rest of this article will refer to variables. But each one could be a parameter except for the variables with expressions. This is because an expression will over write any value passed in.
A common need is to save a file with a date appended to it. This can be done with an expression and a variable. The first example is going to be using one variable without the best practices applied. Of course we are going to need a file system task to save the file for us. One of the nice features of the file system task is the fact that the rename function can rename and move a file.
You simply set the source and destination to a different location. You should never need two file system tasks back to back, with one doing the move and the other doing the rename. The first thing we are going to do is create a file connection in the connection manager of a package. The source in the File system task will be set to this connection. We could use a variable to pass this name in if we needed. In this example the destination is the important part.
We will need a variable on the package also. I will create a variable called strFileName. It is always a best practice to create variables with the first few letters of the name describing the data type and camel case the rest of the variable name. Here is a list of some data types and the extensions to use. Now we set the properties of the variable. Set the property EvaluateAsExpression to true. Then click on the expression ellipse and set the expression to:. Notice the double slashes. These are necessary due to escape characters.
Also notie the double quotes around the literals. Then we simple use three functions.
