Flat File and Transformation Data Types

Flat file data types map to transformation data types that the

Data

Integration Service uses to move data across platforms.

The following table compares flat file data types to transformation data types:

Flat File Data type	Transformation Data type	Range
Bigint	Bigint	Precision of 19 digits, scale of 0
Datetime	Date/Time	Jan 1, 0001 A.D. to Dec 31, 9999 A.D. (precision to the nanosecond)
Double	Double	Precision of 15 digits
Int	Integer	-2,147,483,648 to 2,147,483,647
Nstring	String	1 to 104,857,600 characters
Number	Decimal	For transformations that support precision up to 38 digits, the precision is 1 to 38 digits, and the scale is 0 to 38. For transformations that support precision up to 28 digits, the precision is 1 to 28 digits, and the scale is 0 to 28. If you specify the precision greater than the maximum number of digits, the Data Integration Service converts decimal values to double in high precision mode. If the precision is greater than 15, the Data Integration Service converts decimal values to double in low-precision mode.
String	String	1 to 104,857,600 characters
TimestampWithTZ	TimestampWithTZ	Aug. 1, 1947 A.D to Dec. 31, 2040 A.D. -12:00 to +14:00 Precision of 36 and scale of 9. (precision to the nanosecond) Timestamp with Time Zone data type does not support the following time zone regions: AFRICA_CAIRO AFRICA_MONROVIA EGYPT AMERICA_MONTREAL TimestampWithTZ is applicable only to the native environment.

When the

Data

Integration Service reads non-numeric data in a numeric column from a flat file, it drops the row and writes a message in the log. Also, when the

Data

Integration Service reads non-datetime data in a datetime column from a flat file, it drops the row and writes a message in the log.
