Fields
| Name | Value | Description |
|---|---|---|
| BigInt | 1 | Exact numeric value with precision 19 (if signed) or 20 (if unsigned) and scale 0 (signed: -2[63] <= n <= 2[63] - 1, unsigned:0 <= n <= 2[64] - 1) (SQL_BIGINT). This maps to Int64. |
| Binary | 2 | A stream of binary data (SQL_BINARY). This maps to an Array of type Byte. |
| Bit | 3 | Single bit binary data (SQL_BIT). This maps to Boolean. |
| Char | 4 | A fixed-length character string (SQL_CHAR). This maps to String. |
| DateTime | 5 | Date data in the format yyyymmddhhmmss (SQL_TYPE_TIMESTAMP). This maps to DateTime. |
| Decimal | 6 | Signed, exact, numeric value with a precision of at least p and scale s, where 1 <= p <= 15 and s <= p. The maximum precision is driver-specific (SQL_DECIMAL). This maps to Decimal. |
| Numeric | 7 | Signed, exact, numeric value with a precision p and scale s, where 1 <= p <= 15, and s <= p (SQL_NUMERIC). This maps to Decimal. |
| Double | 8 | Signed, approximate, numeric value with a binary precision 53 (zero or absolute value 10[-308] to 10[308]) (SQL_DOUBLE). This maps to Double. |
| Image | 9 | Variable length binary data. Maximum length is data source-dependent (SQL_LONGVARBINARY). This maps to an Array of type Byte. |
| Int | 10 | Exact numeric value with precision 10 and scale 0 (signed: -2[31] <= n <= 2[31] - 1, unsigned:0 <= n <= 2[32] - 1) (SQL_INTEGER). This maps to Int32. |
| NChar | 11 | Unicode character string of fixed string length (SQL_WCHAR). This maps to String. |
| NText | 12 | Unicode variable-length character data. Maximum length is data source-dependent. (SQL_WLONGVARCHAR). This maps to String. |
| NVarChar | 13 | A variable-length stream of Unicode characters (SQL_WVARCHAR). This maps to String. |
| Real | 14 | Signed, approximate, numeric value with a binary precision 24 (zero or absolute value 10[-38] to 10[38]).(SQL_REAL). This maps to Single. |
| UniqueIdentifier | 15 | A fixed-length GUID (SQL_GUID). This maps to Guid. |
| SmallDateTime | 16 | Data and time data in the format yyyymmddhhmmss (SQL_TYPE_TIMESTAMP). This maps to DateTime. |
| SmallInt | 17 | Exact numeric value with precision 5 and scale 0 (signed: -32,768 <= n <= 32,767, unsigned: 0 <= n <= 65,535) (SQL_SMALLINT). This maps to Int16. |
| Text | 18 | Variable length character data. Maximum length is data source-dependent (SQL_LONGVARCHAR). This maps to String. |
| Timestamp | 19 | A stream of binary data (SQL_BINARY). This maps to an Array of type Byte. |
| TinyInt | 20 | Exact numeric value with precision 3 and scale 0 (signed: -128 <= n <= 127, unsigned:0 <= n <= 255)(SQL_TINYINT). This maps to Byte. |
| VarBinary | 21 | Variable length binary. The maximum is set by the user (SQL_VARBINARY). This maps to an Array of type Byte. |
| VarChar | 22 | A variable-length stream character string (SQL_CHAR). This maps to String. |
| Date | 23 | Date data in the format yyyymmdd (SQL_TYPE_DATE). This maps to DateTime. |
| Time | 24 | Date data in the format hhmmss (SQL_TYPE_TIMES). This maps to DateTime. |
