ODBC and Transformation Data Types

ODBC data types map to transformation data types that the Data Integration Service uses to move data across platforms.

The following table compares ODBC data types, such as Microsoft Access or Excel, to transformation data types:

Data Type	Transformation	Range
Bigint	Bigint	-9,223,372,036,854,775,808 to 9,223,372,036,854,775,807 Precision 19, scale 0
Binary	Binary	1 to 104,857,600 bytes
Bit	String	1 to 104,857,600 characters
Char	String	1 to 104,857,600 characters
Date	Date/Time	Jan 1, 0001 A.D. to Dec 31, 9999 A.D. (precision to the nanosecond)
Decimal	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.
Double	Double	Precision 15
Float	Double	Precision 15
Integer	Integer	-2,147,483,648 to 2,147,483,647 Precision 10, scale 0
Long Varbinary	Binary	1 to 104,857,600 bytes
Nchar	String	1 to 104,857,600 characters
Nvarchar	String	1 to 104,857,600 characters
Ntext	Text	1 to 104,857,600 characters
Numeric	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.
Real	Double	Precision 15
Smallint	Integer	-2,147,483,648 to 2,147,483,647 Precision 10, scale 0
Text	Text	1 to 104,857,600 characters
Time	Date/Time	Jan 1, 0001 A.D. to Dec 31, 9999 A.D. (precision to the nanosecond)
Timestamp	Date/Time	Jan 1, 0001 A.D. to Dec 31, 9999 A.D. (precision to the nanosecond)
Tinyint	Integer	-2,147,483,648 to 2,147,483,647 Precision 10, scale 0
Varbinary	Binary	1 to 104,857,600 bytes
Varchar	String	1 to 104,857,600 characters
