  • New Features

    • OCI8.error_message(message_no) -> string

      Gets the Oracle error message specified by message id.
      Its language depends on NLS_LANGUAGE.

      Note: This method is unavailable if the Oracle client
      version is 8.0.

      When NLS_LANG is AMERICAN_AMERICA.AL32UTF8

      OCI8.error_message(1)

      => “ORA-00001: unique constraint (%s.%s) violated”

      When NLS_LANG is FRENCH_FRANCE.AL32UTF8

      OCI8.error_message(1)

      => “ORA-00001: violation de contrainte unique (%s.%s)”

    • OraNumber#dump -> string

      Returns OraNumber’s internal representation whose format
      is same with the return value of Oracle SQL function DUMP().

      OraNumber.new(100).dump #=> “Typ=2 Len=2: 194,2”
      OraNumber.new(123).dump #=> “Typ=2 Len=3: 194,2,24”
      OraNumber.new(0.1).dump #=> “Typ=2 Len=2: 192,11”

  • Fixed issues

    • Fractional second part is lost when ruby’s Time instance is bound
      to Oracle datatype TIMESTAMP.
      (reported by Raimonds Simanovskis)

      than 38.
      (reported by Raimonds Simanovskis)
