Oracle Data Types

Oracle Data Types

Informatica supports the following Oracle data types when you use Sqoop:

    Blob (supported only for import)

    Char

    Date

    Float

    Long

    Nchar (supported if you configure OraOop)

    Nvarchar (supported if you configure OraOop)

    Number(P,S)

    Timestamp

    Varchar

    Varchar2

Rules and Guidelines for Sqoop Oracle Data Types

Consider the following rules and guidelines when you configure Oracle data types in a Sqoop mapping:
  • If you run a Sqoop mapping on the Blaze engine to export Oracle float data, Sqoop truncates the data.
  • If you run a Sqoop mapping on the Blaze engine to export Oracle timestamp data with nanoseconds, Sqoop writes only three digits to the target.
  • If you configure OraOop and run a Sqoop mapping on the Spark engine to export Oracle timestamp data, Sqoop writes only three digits to the target.
