Class Description

 HDbColumn

 Class for a column in an Oracle table

HDbColumn()

 Default constructor

HDbColumn(const char* cName)

 Constructor creates a column with name cName and default type varchar2(80)
 By default the coulumn is nullable

HDbColumn(HDbColumn& c)

 Copy constructor

~HDbColumn()

 Destrucyor

void setColType(const char* tName, Int_t dlen, Int_t prec=0, Int_t scale=0)

 Sets the column type
 Parameters are:  tName = Name of the type, dlen = length in bytes,
                  prec = data precision, scale = data scale

void setColType(const char* c)

 Sets the column type (e.g  varchar3(20) or number(4,2))

void copyColumn(HDbColumn* p)

 Copies the parameters of a column

void show()

 Shows a column
