Functions
A single bit value of either 0 or 1.
An unsigned single byte (8-bit) value.
The range is 0 to 255.
An unsigned single byte (8-bit) value representing the length of the associated data.
The range is 0 to 255.
A 2-byte (16-bit) or 4-byte (32-bit) value representing a T-SQL NULL value for a character or binary data type.
Please refer to TYPE_VARBYTE (see section 2.2.5.2.3 in MS-TDS.pdf) for additional details.
