APAR status

  • Closed as program error.

Error description

  • Sometimes extra rows that do not qualify might be returned. This
    occurs when you use the fullwidth underscore character X'EFBCBF'
    in the LIKE predicate to match the CLOB datatype in the CLOB
    columns against Unicode databases, and the data's length is less
    than the pattern's length. This is because the fullwidth
    underscore character is 3 bytes.
    

Local fix

  • Apply this fix or change to use single byte underscore.
