Microsoft SQL Server and Transformation Data Types

Microsoft SQL Server data types map to transformation data types that the Data Integration Service uses to move data across platforms.

The following table compares Microsoft SQL Server data types and transformation data types:

Microsoft SQL Server	Range	Transformation	Range
Binary	1 to 8,000 bytes	Binary	1 to 104,857,600 bytes
bigint	- 9,223,372,036,854,775,808 to 9,223,372,036,854,775,807	bigint	-9,223,372,036,854,775,808 to 9,223,372,036,854,775,807 Precision 19, scale 0
Bit	1 bit	String	1 to 104,857,600 characters
Char	1 to 8,000 characters	String	1 to 104,857,600 characters
Date	Jan 1, 0001 A.D. to Dec 31, 9999 A.D.	Date/Time	Jan 1, 0001 A.D. to Dec 31, 9999 A.D.
Datetime	Jan 1, 1753 A.D. to Dec 31, 9999 A.D. Precision 23, scale 3 (precision to 3.33 milliseconds)	Date/Time	Jan 1, 0001 A.D. to Dec 31, 9999 A.D. (precision to the nanosecond)
Datetime2	Jan 1, 0001 A.D. 00:00:00 to Dec 31, 9999 A.D. 23:59:59.9999999	Timestamp	Precision 22 to 27
Decimal	Precision 1 to 38, scale 0 to 38	Decimal	For transformations that support precision up to 38 digits, the precision is 1 to 38 digits, and the scale is 0 to 38. 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.
Float	-1.79E+308 to 1.79E+308	Double	Precision 15
Image	1 to 2,147,483,647 bytes	Binary	1 to 104,857,600 bytes
Int	-2,147,483,648 to 2,147,483,647	Integer	-2,147,483,648 to 2,147,483,647 Precision 10, scale 0
Money	-922,337,203,685,477.5807 to 922,337,203,685,477.5807	Decimal	Precision 1 to 28, scale 0 to 28
nchar	1 to 4000 characters	String	1 to 104,857,600 characters
ntext	1 to 1,073,741,823 bytes	Text	1 to 104,857,600 characters
Numeric	Precision 1 to 38, scale 0 to 38	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.
nvarchar	1 to 4000 characters	String	1 to 104,857,600 characters
Real	-3.40E+38 to 3.40E+38	Double	Precision 15
Smalldatetime	Jan 1, 1900, to June 6, 2079 Precision 19, scale 0 (precision to the minute)	Date/Time	Jan 1, 0001 A.D. to Dec 31, 9999 A.D. (precision to the nanosecond)
Smallint	-32,768 to 32,768	Integer	-2,147,483,648 to 2,147,483,647 Precision 10, scale 0
Smallmoney	-214,748.3648 to 214,748.3647	Decimal	Precision 1 to 28, scale 0 to 28
Sysname	1 to 128 characters	String	1 to 104,857,600 characters
Text	1 to 2,147,483,647 characters	Text	1 to 104,857,600 characters
Timestamp	8 bytes	Binary	1 to 104,857,600 bytes
Tinyint	0 to 255	Integer	-2,147,483,648 to 2,147,483,647 Precision 10, scale 0
Uniqueidentifier	Precision 38, scale 0	String	To successfully move or change Uniqueidentifier data, ensure that the data is in the following format: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx where x is a hexadecimal digit in the range 0-9 or a-f.
Varbinary	1 to 8,000 bytes	Binary	1 to 104,857,600 bytes
Varchar	1 to 8,000 characters	String	1 to 104,857,600 characters
