The Like operator is useful for selecting records to include or exclude from your report.
Usage
x like y
{fieldname} like "c?n*"
This operator tests to see if the contents of {fieldname} matches a pattern that you specify in a character string "c?n*". If the contents of the field do fit the pattern "c?n*", then the formula returns the value True. If the field starts with anything else, the formula returns False.
Use the wildcard symbols ? and * to stand for variable characters. The ? stands for a single character. The * symbol stands for any number of characters.
Examples
{customer.FIRST NAME} like "D?n"
TRUE, where {customer.FIRST NAME} = Dan or Don.
{customer.FIRST NAME} like "D?n"FALSE, where {customer.FIRST NAME} = Doug or Rob.
{customer.LAST NAME} like "*s?n*"TRUE, where {customer.LAST NAME} = Johnson or Olson or Olsen.
{customer.LAST NAME} like "*s?n*"FALSE, where {customer.LAST NAME} = Johnston or Smith.
