I've got a CSV file with 11 columns and I have a MySQL table with 9 columns.
The CSV file looks like:
col1, col2, col3, col4, col5, col6, col7, col8, col9, col10, col11
and the MySQL table looks like:
col1, col2, col3, col4, col5, col6, col7, col8, col9
I need to map the columns 1-8 of CSV file directly to the first 8 columns of the MySQL table. I then need to skip the next two columns in the CSV file and then map column 11 of CSV file to column 9 of MySQL table.
At the moment I am using the following SQL command:
LOAD DATA LOCAL INFILE 'filename.csv' INTO TABLE my_table
FIELDS TERMINATED BY ','
ENCLOSED BY ''
LINES TERMINATED BY '\n'
But the above code maps the first 9 columns of CSV file to the 9 columns in the MySQL table.
You can also discard an input value by assigning it to a user variable and not assigning the variable to a table column:
LOAD DATA INFILE 'file.txt'
INTO TABLE t1 (column1, @dummy, column2, @dummy, column3);
