Join Matt Francis for an in-depth discussion in this video Create an initial filter from a surname, part of Tableau 10 for Data Scientists.
- [Narrator] A useful string calculation…would be the ability to create a filter…so we could look up somebody's surname…by their first initial.…In this example, we've got fifteen thousand records…of runners who've competed in a race.…The first step is to split the name…into forename and surname…then take the surname, split off the initial…and then create a filter using that information.…First, let's split the name.…We just go to name, transform, and split.…
We've now got our two fields, one named forename…and surname.…That should place these on our field.…There we go.…Next thing we need to do is split off the first character…of our surname to create our initial filter.…So for that, we select the surname and do calculated field.…The function we're gonna use is a string function…which can be found here.…
We're gonna use the left function.…This returns a specified number of characters…from the start of a given string.…So for our example, we're gonna say left, the string,…and the number of characters.…We only want the first character so we give that one.…
