limit Parameter

The limit parameter defines the maximum number of times that a pattern can be matched within a column.

NOTE: The limit parameter cannot be used with the following parameters: at, positions, or delimiters.

A set of new columns is generated, as defined by the limit parameter. Each matched instance populates a separate column, until there are no more matches or all of the limit-generated new columns are filled.
