Microsoft Connector for Oracle data type support

  • Article

Applies to: SQL Server SSIS Integration Runtime in Azure Data Factory

SSIS components for Oracle do not support all Oracle data types. Columns with unsupported data types will have a warning when designing packages in SSDT and will be deleted from mapping columns. Data cannot be loaded to a column with an unsupported data type.

Data type mapping

The following table shows the Oracle database data types and their default mapping to SSIS data types. It also shows the unsupported Oracle data types.

Oracle Database Data Type SSIS Data Type Comments
VARCHAR2 DT_STR
NVARCHAR2 DT_WSTR
CHAR DT_STR
NUMBER DT_R8 This can be changed to DT_NUMERIC with specific precision and scale. Precision and scale are defined by user per the need. The output will be the column data as a number with fixed precision and scale.
NUMBER(P, S) When the scale is 0, according to the precision (P)
  • DT_I1
  • DT_I2
  • DT_I4
  • DT_NUMBERIC(P,0)
