PM81851: HPU NATIVE MODE SQL EXPRESSION DATE(CHAR_DATA) WHERE CHAR_DATA IS A NON CONSTANT CHAR TYPE DATA IS INCORRECTLY EVALUATED

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When processed in native mode, an SQL expression DATE(char_data)
  where char_data is a non constant char type data is incorrectly
  evaluated which leads to the following issues:
  - if the DATE(char_data) expression is part of the output
  columns, an evaluation error is reported by issuing
  messages such as "227 * EXPRESSION EVALUATION ERROR"
  and no rows are unloaded
  - if the DATE(char_data) expression is part of a
  predicate used in a WHERE clause the number of output
  rows is incorrect and usually equals to zero.
