Part Number B10118-01
The code wizard supports all data types, except for PL/SQL tables. When a PL/SQL table is used, an "unsupportedType" key word will be used instead, and the generated code will not compile.
The output code may have to be modified for handling Null values. For example, when a VB variable is initialized to a parameter value, an isNull() check may have to be added if Null values are expected. Nulls are correctly handled for VB variables of type variant and object.
