Class Description


 HDbColumnType

 Base class for Oracle column types

 Derived classes are:
   HDbColCharType  for Oracle type CHAR
   HDbColVcType                    VARCHAR2
   HDbColNumType                   NUMBER
   HDbColDateType                  DATE
   HDbColRowidType                 ROWID
   HDbColLongType                  LONG
   HDbColRawType                   RAW

   Because of problems to convert LONG and RAW types to VARCHAR2, the
   datatypes LONG and RAW are actually not supported.




 HDbColNumType(Int_t p, Int_t s)
               : HDbColumnType("NUMBER",sizeof(Double_t),p,s) 


 Constructor for type NUMBER with specified precision and scale (default precision 40)


TString getTypeString() 


 Returns the type string "NUMBER(p,s)"


TString getSelectString(const char* col, const char*) 


 Returns the string to convert the number column to characters
 null string if column value is null


TString getNvlSelectString(const char* col, const char*, const char* sNull) 


 Returns the string to convert the number column to characters or to replace by the
 specified null string if the column value is null
