Importing CSV file (in Japanese) into MySQL

Operating environment

macOS Sierra 10.12.6


What I want to do:

I would like to manage roster management and receptionist lists with MySQL.

How I will make it done:

I will import / export csv data (with Japanese) somehow to MySQL. Eventually, with Node - RED or something like that, you can make searching, sorting, writing, exhaling results, etc

1. Excel data preparation:

This time I made an excel file like this: Since I still have trouble, I\'d like to make it all strings. Even if you input 001 as usual, it will be kindly converted into a number, so let\'s make it string by entering \'001.

Save to the desktop

Save as "CSV UTF - 8".


MySQL\'s will do it all for me.

I installed it with homebrew, but I will skip how to do it.

2-1. Prepare the database

Please make database properly.

I will also skip through it.

2-2. Prepare a table

Please prepare the following table.

id:varchar(20) name:varchar(20) type:varchar(20)

  • how to create the table
mysql> create table TABLE_NAME (here i use "tablepkmn")
    -> (id varchar(20), name varchar(20), type varchar(20));
Query OK, 0 rows affected (0.02 sec)

3. Move the data to an accessible place

In order to load it you need to move the data to a location that everyone can access.

csv data: desktop → / tmp

  • to move the file cp ~/Desktop/hoge.csv /tmp

That will make a copy.

4. Importing data

We assume that the database is in use. Table name is tablepkmn, csv data name is hoge.csv Please change as appropriate.

4.1 Import

  • Make an import
mysql> load data infile "/tmp/hoge.csv"
    -> into table tablepkmn
    -> fields terminated by \',\'
    -> enclosed by \'"\'
    -> lines terminated by \'\n\';

It is OK if this comes out.

4.2 Confirm the table

To display all the content: select * from tablepkmn \G

5. Error appeared

I got a lot of errors anyway at the time of importing, so I will summarize it.

- If secure-file-priv is wrong

** ERROR 1290 (HY000): The MySQL server is running with the --secure-file-priv option so it cannot execute this statement **

How to fix

Reference: [MySQL] Attempted to export data as CSV, it caught on secure-file-priv It seems that it can be solved by emptying secure_file_priv

  • Checkout the content of secure_file_priv file:
mysql> SELECT @@global.secure_file_priv;
| @@global.secure_file_priv |
| NULL                      |
1 row in set (0.00 sec)

Make it empty instead of NULL. This seems to be described in my.cnf.

① Find my.cnf

Reference: Set my.cnf in MySQL that you put in Homebrew

  • From a new terminal
$ mysql --help | grep my.cnf
/etc/my.cnf /etc/mysql/my.cnf /usr/local/etc/my.cnf ~/.my.cnf 

Four results were returned. This is read from the left, but it will be overwritten more and more in the order in which it was read. So I add the valid ~/.my.cnf to the right. Note: Because I am addicted to the order of reading my.cnf, so I summarized it

② Replace my.cnf

Rewrite with vim. Reference: Commonly used Vim command summary

  • In vim [mysqld] should be as follows. Comment out is acceptable.
secure-file-priv = ""

③ Reset the Server

Exit with control + D and restart with mysql.server restart.

After reentering the database, I confirmed that it was empty safely with SELECT @@ global.secure_file_priv;

Garbled characters

Apparently it seems to be a character code problem.

■ Solution Reference: Set character code to utf 8 with mysql Let character_set_database be utf-8.

① Check the character code

Enter show variables like "chara%";

| Variable_name            | Value                      |
| character_set_client     | utf8                       | 
| character_set_connection | utf8                       | 
| character_set_database   | latin1                     | ←make it utf8 here
| character_set_filesystem | binary                     |
| character_set_results    | utf8                       |
| character_set_server     | utf8                       |
| character_set_system     | utf8                       |
| character_sets_dir       | /usr/share/mysql/charsets/ |

② Change inside the my.cnf

I will use vim again to modify ~/.my.cnf that I changed.

  • ~/.my.cnf
character-set-server=utf8 #add the ending of mysqld section

default-character-set=utf8 #Add client section

③ Restart server

Exit with control + D and restart with mysql.server restart. Type show variables like "chara%"; and it was rewritten safely.
