Hi I am loading data from flat file to my table through SSAS I want to derive a conditional column to append zeros to is numeric data in the zip code column when the length is <5

ForExample
the above expression is not working,request to guide me
Thank you.

Answer 1

Is this for SSIS? My last answer assumed that this was an SSAS column because the SSAS tag. If this is a date load via SSIS, you can use a Script Component to do this instead of a Derived Column. The example below uses C# and the CustomerZipCode column will need to be added in the Input Columns pane with the ReadWrite usage type. The TryParse method checks if the column is numeric and will return false if the column contains any text. The String constructor is used to create the zeroesToAppend string, which is set to the number of zeroes below 5 that the length of the column is, and afterwards this is added to the beginning of the column. This will go in the Input0_ProcessInputRow method, which is executed once for each row from the input.
public override void Input0_ProcessInputRow(Input0Buffer Row)
{
int i;
if (int.TryParse(Row.CustomerZipCode, out i) && Row.CustomerZipCode.Length < 5)
{
string zeroesToAppend = new String('0', 5 - Row.CustomerZipCode.Length);
Row.name = String.Concat(zeroesToAppend, Row.CustomerZipCode);
}
}
