Matching alphabet for a particular field

Hi

  I am trying to use SAP BODS Query to filter a table with a field XYZ which has 'any alphabet'

Field XYZ is varchar(9)

I tried   match_pattern(upper(XYZ), 'X')  but I am afraid it will filter the field with only single character entries like 'a' or 'c'.

How can I filter also if multicharacter alphabets are present like 'abc' or 'cbz'

I am using BODS version 14.1.1.210

Cheers
