I know that, but how to check the number of the column? due the table is very big, and do i need count that manually? or can i filter that column by key words?
like: name class .............. age
kevin 5 26
so i do not know the exactly column of the age, but i know there is a column include the "age" key words.
can i filter that column by keywords?
thanks very much!
