A total of 12, a check for each data type, the system is not really look contain meaningful data, or the data types are defined in the table structure, and never stored record meaningful values .
select * from user_tab_cols t where t.DATA_TYPE ='LONG';
You can get
Such a table, we were to find where each side of the table, the table to see if there are data records, which in this field is not entirely empty value, as long as a true rms, then the data will need to be included in our content to be tested.
How we will deal with a variety of different types of systems, the means to be adopted into four

We need to support
2, the digital type NUMBER INTEGER
We need to support
3, the date of type DATE TIMESTAMP
We need support, the support of the timestamp of the doubt
4, binary type BLOB, CLOB, NCLOB, BFILE
CLOB may be able to support the other should not support editing
5, RAW & LONG RAW type
not support
6、 ROWID & UROWID
It does not support, the interface does not show
