Is there a way to skip columns when using the column_list attribute of DATA LOAD?

For example, if I wanted ignore the fourth column in the data file I'm trying to load how would I do it?

I tried the following but MySQL would not accept it:

(area,status,property_type,listing_num,,agent_id)

 
Where were you using the column list in the query? MySQL requires that you use it at the end.

Also, if you're skipping a column, don't use a blank column name between commas, as you have here:

(area,status,property_type,listing_num,,agent_id)

Simply don't mention the column name:

(area,status,property_type,listing_num,agent_id)


Keep in mind that the column-list tells MySQL with which column to associate the data in the file. You don't have the specify the columns of a table in order -- the clause exists to populate a table where, like in your case, you are not populating a column or when the order of the data in the file does not match the order of the columns in the table.

The column I want to skip is in the data file not in the table. As I understand it the order in the column_list is directly related to the order of the columns in the data file. So how do I skip over, for example, the fourth column in the data file?

 
One way would be to alter the table to add a column into which that data will go. Then alter the table a second time after importing the data to remove that column.
