Converts data to SQL statements or read data from SQL tables.
Class for serializing/deserializing object to/from SQL data base. It redefines most of TBuffer class function to convert simple types, array of simple types and objects to/from TSQLStructure objects. TBufferSQL2 class uses streaming mechanism, provided by ROOT system, therefore most of ROOT and user classes can be stored. There are limitations for complex objects like TTree, TClonesArray, TDirectory and few other, which can not be converted to SQL (yet).

This method inform buffer data of which class now will be streamed.
When reading, classversion should be specified as was read by TBuffer::ReadVersion().
ClassBegin(), ClassEnd() & ClassMemeber() should be used in custom class streamers to specify which kind of data are now streamed to/from buffer. That information is used to correctly convert class data to/from "normal" sql tables with meaningfull names and correct datatypes. Without that functions data from custom streamer will be saved as "raw" data in special streamer table one value after another Such MUST be used when object is written with standard ROOT streaming procedure, but should be read back in custom streamer. For example, custom streamer of TNamed class may look like:

Creates TSQLObjectData for specified object id and specified class.
Object data for each class can be stored in two different tables. First table contains data in column-wise form for simple types like integer, strings and so on when second table contains any other data which cannot be converted into column-wise representation. TSQLObjectData will contain results of the requests to both such tables for concrete object id.
