Members

Member name Description
BigInt A 64-bit signed integer.
Binary A fixed-length byte array ranging between 1 and 8,000 bytes.
Bit An unsigned bit value that can be 0, 1, or a null reference.
Char A fixed-length byte array of non-Unicode (256 code page) characters ranging between 1 and 8,000 characters.
Date Date object represents any valid Gregorian calendar date between '0001-01-01' CE and '9999-12-31' CE.
DateTime A DateTime system object value that specifies a date and time between January 1, 1753 and December 31, 9999 to an accuracy of 3.33 milliseconds.
DateTime2 DateTime2 is considered an extension of the existing DATETIME object with a large date range and large default fractional precision. Values that represent any valid Gregorian calendar date between ‘0001-01-01’ CE and ‘9999-12-31’ CE combined with any valid time of day based on a 24-hour clock.
DateTimeOffset DateTimeOffset returns valid Gregorian calendar date between `0001-01-01’ and ‘9999-12-31’ with any valid time of day based on a 24 hour format between ’00:00:00’ and max ’23:59:49.9999999’. Included in the DateTimeOffset is a time zone offset that must be between ‘-14:00’ and ‘+14:00’.
Decimal A fixed precision and fixed scale numeric value between -1038 -1 and +1038 -1.
Float An 8-byte floating point number within the range of -1.79E +308 through 1.79E +308.
Geography Geography spatial type represents data in a round-earth coordinate system. The SQL Server geography data type stores ellipsoidal (round-earth) data, such as GPS latitude and longitude coordinates.. 
Geometry Geometry spatial type represents data in a Euclidean (flat) coordinate system.
HierarchyId HierarchyID type represents data in a hierarchy structure. For more information, see Tutorial: Using the hierarchyid Data Type
Image A variable-length byte array ranging from 0 to 231 -1 (or 2,147,483,647) bytes.
Int A 32-bit signed integer.
Money A Decimal system object value that specifies a currency value ranging from -263 (or -922,337,203,685,477.5808) to 2 63 -1 (or +922,337,203,685,477.5807) with an accuracy of 1 in 10,000 of a currency unit.
NChar A fixed-length byte array of Unicode characters ranging between 1 and 4,000 characters.
None No data type.
NText A variable-length byte array of Unicode data with a maximum length of 230 - 1 (or 1,073,741,823) characters.
Numeric A fixed precision and fixed scale numeric value between -1038 -1 and +1038 -1.
NVarChar A variable-length byte array of Unicode characters ranging between 1 and 2^63 characters.
NVarCharMax The NVARCHAR(MAX) type.
Real A 4-bit floating point number within the range of -3.40E +38 through 3.40E +38.
SmallDateTime A DataTime system object value that specifies a date and time between January 1, 1900 and June 6, 2079 to an accuracy of one minute.
SmallInt A 16-bit signed integer.
SmallMoney A Decimal system object value that specifies a currency value ranging from -214,748.3648 to +214,748.3647 with an accuracy of 1 in 10,000 of a currency unit.
SysName A system name string.
Text A variable-length byte array of non-Unicode (256 code page) data with a maximum length of 231 -1 (or 2,147,483,647) characters.
Time Time object returns values for any valid time of day based on a 24 hour clock between '00:00:00' and max '23:59:59:9999999'.
Timestamp An automatically generated byte array value, which is guaranteed to be unique within a database.
TinyInt An 8-bit unsigned integer.
UniqueIdentifier A globally unique identifier (or GUID).
UserDefinedDataType A user-defined data type.
UserDefinedTableType A SQL Server common language runtime (CLR) user-defined table type.
UserDefinedType A SQL Server common language runtime (CLR) user-defined type.
