Given that the table had 1100 columns I am not sure I wanted to see it:)

Still the OP did give it to us in description:

"I create a table with 1100 columns with data type of varchar, and hope
the COPY command will auto transfer the csv data that contains some
character and date, most of which are numeric."

In retrospect I should have pressed for was a more complete description

"And some the values in the csv file contain nulls, do this null values
matter? "
