Transformation Data Types

Transformation Data Types

The following table describes the transformation data types:

Data Type	Size in Bytes	Description
Array	Unlimited number of characters.	Complex data type. You can use arrays with complex sources and targets.
Bigint	8 bytes	-9,223,372,036,854,775,808 to 9,223,372,036,854,775,807 Precision of 19, scale of 0 Integer value.
Binary	Precision	1 to 104,857,600 bytes You cannot use binary data for flat file sources.
Date/Time	16 bytes	Jan 1, 0001 A.D. to Dec 31, 9999 A.D. Precision of 29, scale of 9 (precision to the nanosecond) Combined date/time value.
Decimal	8 bytes (if high precision is off or precision is greater than 38) 16 bytes (if precision <= 18 and high precision is on) 20 bytes (if precision > 18 and <= 28) 24 bytes (if precision > 28 and <= 38)	Decimal value with declared precision and scale. Scale must be less than or equal to precision. 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.
Double	8 bytes	Double-precision floating-point numeric value. You can edit the precision and scale. The scale must be less than or equal to the precision.
Integer	4 bytes	-2,147,483,648 to 2,147,483,647 Precision of 10, scale of 0 Integer value.
Map	Unlimited number of characters.	Complex data type. You can use maps with complex sources and targets.
String	Unicode mode: (precision + 1) * 2 ASCII mode: precision + 1	1 to 104,857,600 characters Fixed-length or varying-length string.
Struct	Unlimited number of characters.	Complex data type You can use structs with complex sources and targets.
Text	Unicode mode: (precision + 1) * 2 ASCII mode: precision + 1	1 to 104,857,600 characters Fixed-length or varying-length string.
timestampWithTZ	40 bytes	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
