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.
