Importing a csv into mysql via command line

Question

I'm trying to import a very large .csv file (~4gb) into mysql. I was considering using phpmyadmin, but then you have a max upload size of 2mb. Someone told me that I have to use the command line.

I was going to use these directions to import it: http://dev.mysql.com/doc/refman/5.0/en/mysqlimport.html#c5680

What would be the command to set the first row in the .csv table as the column names in the mysql table? This option is available through phpmyadmin, so their must be a mysql command line version too, right?. Please help me. Thank you.

Answer 1

Try this command

 load data local infile 'file.csv' into table table  fields terminated by ','  enclosed by '"'  lines terminated by '\n'  (column1, column2, column3,...) 

The fields here are the actual table fields that the data needs to sit in. The enclosed by and lines terminated by are optional and can help if you have columns enclosed with double-quotes such as Excel exports, etc.

For further details check the manual.

For setting the first row as the table column names, just ignore the row from being read and add the values in the command.

Answer 2

try this:

mysql -uusername -ppassword --local-infile scrapping -e "LOAD DATA LOCAL INFILE 'CSVname.csv'  INTO TABLE table_name  FIELDS TERMINATED BY ',' LINES TERMINATED BY '\n'" 

Answer 3

You can simply import by

mysqlimport --ignore-lines=1 --lines-terminated-by='\n' --fields-terminated-by=',' --fields-enclosed-by='"' --verbose --local -uroot -proot db_name csv_import.csv

Note: Csv File name and Table name should be same

Answer 4

You could do a

mysqlimport --columns='head -n 1 $yourfile' --ignore-lines=1 dbname $yourfile`

That is, if your file is comma separated and is not semi-colon separated. Else you might need to sed through it too.
