Hi All
I have a challenge to identify a particular pattern in the data, for example
AB, YZ
AB, AB, YZ
AB, AB, AB, YZ
...
if string AB comes before string YZ, i need to identify these records, but AB can be any number of times (i.e. 1 to n)
Any thoughts?
So in this example, all three records would be identified, correct?
Try to check by:
if scan(<variable namr>, -1, ' ,') = 'BZ' and /* last string */
scan(<variable namr>, -2, ' ,') = 'AB'
then ...; else ...;
Regular expressions are all about text patterns.
if prxMatch("/AB[, ]+YZ/i", string) then <do something>;
would match your example pattern. The pattern says: AB followed by one or more comma or a space characters, followed by YZ.
If it is really as simple as your example then no need for regular expressions.
index(string,'AB, YZ')
