Data Members

    protected:

      TSQLFile* fFile   !  pointer on SQL file
          Int_t fKeyId  !  key identifier in KeysTables

Class Description

 TKeySQL is represents a metainforamtion about object, which was written to
 SQL database. It keeps object id, which used to locate object data
 from database tables.
________________________________________________________________________

 default constructor

 Creates TKeySQL and convert obj data to TSQLStructure via TBufferSQL2

 Creates TKeySQL and convert obj data to TSQLStructure via TBufferSQL2

 Create TKeySQL object, which correponds to single entry in keys table

 TKeySQL destructor

 Browse object corresponding to this key

 Removes key from current directory
 Note: TKeySQL object is not deleted. You still have to call "delete key"

  convert object to sql statements and store them in DB

 Read object derived from TObject class
 If it is not TObject or in case of error, return 0

 read object of any type from SQL database
