PH33305: After PH17958, ABENDS0CA or 227 * EXPRESSION EVALUATION ERROR or incorrout for an unload involving DECIMAL division

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• After the application of the fix for PH17958, a logical unload
  run in native mode fails with one of the following error:
  
  
  - an ABENDS0CA occurs
  
  
  - the 227 * EXPRESSION EVALUATION ERROR error message is issued
  
  
  - the output field for an expression involving a division with
  DECIMAL contains an incorrect value (e.g. the decimal value is
  unduly replaced by zeroes),
  
  
  - the unload completes with completion code 8 after having
  issued the following message:
  INZU238E UNEXPECTED UNSUPPORTED SELECT UTILITY CANNOT SWITCH TO
  SQL PROCESSING REASON 0Xb0034 / reason_code
  
  
  This only occurs if the logical unload involves an SQL
  expression whose evaluation requires the casting of one of the
  operands into a DECIMAL. The issue occurs only if some specific
  additional conditions about the operands are fulfilled. These
  conditions cannot be comprehensively listed or described. Some
  of the conditions on the operators are:
  
  
  - In a division, the numerator is a DECIMAL(p,s) value and the
  denominator is an integer constant which value is greater than
  the biggest value of the DECIMAL(P,S) data type resulting from
  the division of DECIMAL(p,s) value by the integer constant.
  
  
  - In a division, the numerator is a DECIMAL(p,s) value and the
  denominator is is a DECIMAL(p',s') value that is greater than
  the the biggest value of the DECIMAL(P,S) data type resulting
  from the division of DECIMAL(p,s) value by the DECIMAL(p',s')
  value.
  
  
  - In a multiplication, an operand is a DECIMAL and needs to be
  converted into a DECIMAL with greater precision to match the
  output precision.
  
  
  - In a multiplication, one operand is a DECIMAL, and the other
  one needs to be converted into DECIMAL to match the output type.
  

Local fix

• if applicable, consider runnng the unload in SQL mode by
  specifying the DB2 FORCE option.
