The Split command lets you divide any column up at designated points. Usually, you will split columns on characters such as commas, pipes, spaces, equals signs, or other delimiters. Split columns take the same column type as those they split from. For example, if you split a column with type VARCHAR, all split columns will be of type VARCHAR. Split columns are named after the original column, with _1, _2, and so on appended. After you split columns, you can use the Rename Column command to change these names.
