User Defined Types (UDT)
CLR functions use UDTs as input and output parameters.
All these data contracts are added to an SQL Server instance in the same script that adds the CLR functions (see the Install page). By default all UDTs are added to the wds namespace.
Most of the UDTs that are used as input parameters can be initialized from a string. Review the data contracts documentation below for the details.
Data contract UDTs fields are readable and writable. When a UTS has been initialized from a string, the corresponding fields are prefilled with values from the string but they all can be overridden.
In general initialization strings have the following format FieldName1: FieldValue1; FieldName2: FieldListValue1, FieldListValue2;
UDTs have validation methods to check required fields. The validation performs when UDTs are used (not on initialization).
