IBProvider now supports free ways of NULL-processing
In new IBProvider release three ways of NULL processing are supported:
- using special NULL flag
- using type DBTYPE_NULL
- using Variant with VT_NULL type
Previous versions of IBProvider support only first way of NULL-processing. If client set NULL using other ways (DBTYPE_NULL, VARIANT_WITH_NULL) IBProvider raise error conversion.
