If you do not want to work with arrays in C like we did in the example 3, there is another option. This example will import the list of files to SQL Server and then download the files using the list. We will create a table in that database. In the Name of the table or view, press the New Button:. In SQLStatements do a select filename from listoffiles:. In Result Set, specify 0 as the Result Name.
In Variable Name, add the variable named filename created in the example This enumerator will get the information from the SQL table created. In ADO object source variable, select the filename variable and in Enumeration mode select Rows in the first table:. In variable Mapping, select the User:filename variable and in Index put 0.
A typical error is that the value DBNull is assigned to variable. In the progress page, you can see the error message:. Error: The type of the value DBNull being assigned to variable "User::filename" differs from the current variable type String. Variables may not change type during execution. Variable types are strict, except for variables of type Object. This error occurs because the parameter is a string and it is compared with a database object. To fix this problem change the filename variable data type to object:.

Is the best option if there are multiple files and it is not easy to convert the list of files to an array. Log in or register to rate. Join the discussion and add your comment.

As soon as I read your comment, I got the first part knocked out. Now working on the find and substring as I only really need to grab the GUID portion of the string and store it in a variable.
Ok let me know if you got it working or if you need any help. In the PostExecute method of the Script Component you can fill a readwrite variable. URL End Sub. Joost Hello.
