size_t DataSize () const
 The maximum size of the type attribute. This length is returned in bytes and not characters for strings and raws. It returns 22 for NUMBERs.

 Typecode.
 
OCI::TypeCode DataTypeCode () const
 The data type of the type attribute.
 
size_t ArraySize () const
 The number of elements in an array. It is only valid for collections that are arrays.
 
WideString Name () const
 Type attribute name.
 
Int16 Precision () const
 The precision of numeric type attributes. If the precision is nonzero and scale is - 127, then it is a FLOAT; otherwise, it is a NUMBER( precision, scale ). When precision is 0, NUMBER( precision, scale ) can be represented simply as NUMBER.
