How do I get the native data type like we get in ORACLE using

OCIAttrGet(colHandle, OCI_DTYPE_PARAM, (dvoid *) &dataType, 0,
OCI_ATTR_DATA_TYPE, m_errorHandle);

It will return &datatype value for:
VARCHAR2 - 1
NUMBER - 2
Date - 12

How do we achieve this in MYSQL 5.1?
I saw in manual but not found any pointer. There is no any point described for native data types value.
