Sampling components in an SSIS data flow to create a representative sample of the data to profile. Note that when sampling data, care must be taken to ensure the data is truly representative, or the results can be misleading. Generally it s better to profile the entire data set.

Why would you want to make the Data Profiling task dynamic Well, as an example, think about profiling a new database. You could create a new SSIS package, add a Data Profiling task, and use the Quick Profile option to create profile requests for all the tables in the database. You d then have to repeat these steps for the next new database that you want to profile. Or what if you don t want to profile all the tables, but only a subset of them To do this through the task s editor, you would need to add each table individually. Wouldn t it be easier to be able to dynamically update the task to profile different tables in your database Most tasks in SSIS can be made dynamic by using configurations and expressions. Configurations are used for settings that you wish to update each time a package is loaded, and expressions are used for settings that you want to update during the package execution. Both expressions and configurations operate on the properties of tasks in the package, but depending on what aspect of the Data Profiling task you want to change, it may require special handling to behave in a dynamic manner.

Because the Data Profiling task uses connection managers to control the connection to the database, it is relatively easy to change the database it points to. You update the connection manager, using one of the standard approaches in SSIS, such as an expression that sets the ConnectionString property, or a configuration that sets the same property. You can also accomplish this by overriding the connection manager s setting at runtime using the /Connection switch of DTEXEC. Bear in mind that although you can switch databases this way, the task will only work if it is pointing to a SQL Server database. Also, connection managers only control the database that you are connecting to, and not the specific tables. The profile requests in the task will still be referencing the original tables, so if the new database does not contain tables with the same names, the task will fail. What is needed is a way to change the profile requests to reference new tables.

As noted earlier, you can configure the Data Profiling task through the Data Profiling Task Editor, which configures and stores the profile requests in the task s ProfileRequests property. But this property is a collection object, and collection objects can t be set through expressions or configurations, so, at first glance, it appears that you can t update the profile requests. Fortunately, there is an additional property that can be used for this on the Data Profiling task. This is the ProfileInputXml property, which stores the XML representation

of the profile requests. The ProfileInputXml property is not visible in the Properties window in BIDS, but you can see it in the Property Expressions Editor dialog box, or in the Package Configuration Wizard s property browser. You can set an XML string into this property using either an expression or a configuration. For it to work properly, the XML must conform to the DataProfile.xsd schema mentioned earlier.

Setting the ProfileInputXml property
So how can you go about altering the ProfileInputXml property to profile a different table One way that works well is to create a string variable in the SSIS package to hold the table name (named TableName) and a second variable to hold the schema name (named SchemaName). Create a third variable that will hold the XML for the profile requests (named ProfileXML), and set the EvaluateAsVariable property of the ProfileXML variable to True. In the Expression property, you ll need to enter the XML string for the profile, and concatenate in the table and schema variables. To get the XML to use as a starting point, you can configure and run the Data Profile task with its output directed to a file. You ll then need to remove the output information from the file, which can be done by removing all of the elements between the <DataProfileOutput> and <Profiles> tags, so that the XML looks similar to listing 1. You may have more or less XML, depending on how many profiles you configured the task for initially.
