title: Concatenating string from SSIS for loop task
body: <p>I have an SSIS package which loops over an array of dates. On each iteration I would like to append the current date to a string to get a full string of all the dates iterated.</p>
  
  <p>What I did was to make an expression where: dateconcatvariable + ", " +currentdatevariable</p>
  
  <p>However, dateconcatvariable  is resetting on every iteration of the for loop and so in the end I end up with the last date iterated over instead of all the dates.</p>
  
  <p>the variable is a package level variable.</p>
  
  <p>Any ideas on how to get a concatenation to happen on SSIS?</p>
  
  <p>Thanks!</p>
