有關oracle~~勁urgent!!!!

用oracle upload緊一個table~
係copy and paste既~
點知做到去Table Properties個到就話有error:

"1 error has occurred

* The identified column name is an Oracle reserved word. Please choose another name."

整黎整去都唔知邊到有問題~
d column name明明之前upload既table都有用過~
但依家唔知點解唔得~
有冇高人可以話我知發生咩事同埋點solve個problem丫?
做緊project嫁~
依家jam左我都唔知點算~
唔該幫幫忙丫~
