TDS Null handling options

TDS supports handling of null values within messages. You can use the message set property Boolean Null Representation to specify the value to be used for Boolean Null representation. You can use the object properties Encoding Null and Encoding Null Value to control how null handling is represented for individual objects.

You can select the Encoding Null property from the three enumerated values NULLPadFill, NULLLogicalValue, and NULLLiteralValue:

The use of the Encoding Null Value property is dependent on the value that you select for the Encoding Null property described above. Null values are not defined for binary types. The properties Encoding Null and Encoding Null Value are therefore not set for binary types.
