Import CSV Data

Import CSV and TSV files into MariaDB Cloud with the LOAD DATA LOCAL INFILE statement, executable from any MariaDB client or connector with local-infile support enabled.

MariaDB Cloud customers can import data into a MariaDB Cloud service using the LOAD DATA LOCAL INFILE SQL statement:

• The LOAD DATA LOCAL INFILE statement can import data from TSV and CSV files

• The LOAD DATA LOCAL INFILE statement can be executed by any client or connector

Make sure your schema is already created in the database. If you need to import entire databases or create tables, you should use mariadb-import.

Enable Local Infiles

Support for local infiles must be enabled on the client side and on the MariaDB Cloud service.

Enable Local Infiles on the Client or Connector

To execute the LOAD DATA LOCAL INFILE statement, most clients and connectors require a specific option to be enabled.

If you are using mariadb client, the --local-infile option must be specified.

Enable Local Infiles in MariaDB Cloud

Support for local infiles must be enabled on the MariaDB Cloud service.

For MariaDB Cloud services that use MariaDB Server, the local_infile system variable must be enabled:

• For Replicated Transactions and Single Node Transactions services, the local_infile system variable is OFF by default

Configuration Manager can be used to modify the value of the local_infile system variable.

Import Data

1. Determine the connection parameters for your MariaDB Cloud service.

2. Connect with the mariadb client and specify the -local-infile option, which is needed by the next step:

mariadb --host FULLY_QUALIFIED_DOMAIN_NAME --port TCP_PORT \
      --user DATABASE_USER --password \
      --ssl-verify-server-cert \
      --default-character-set=utf8 \
      --local-infile

After the command is executed, you will be prompted for a password. Enter the default password for your default user, the password you set for the default user, or the password for the database user you created.

For each table that you want to import, execute the LOAD DATA LOCAL INFILE statement to import the data from the TSV or CSV file into your MariaDB Cloud database service.

For a TSV file:

LOAD DATA LOCAL INFILE 'contacts.tsv'
INTO TABLE accounts.contacts;

For a CSV file:

LOAD DATA LOCAL INFILE 'contacts.csv'
INTO TABLE accounts.contacts
FIELDS TERMINATED BY ',';

Using a Connector

If you are using a MariaDB Connector, then you must select the method for the specific connector from the list below.

If you are using MariaDB Connector/C, the MYSQL_OPT_LOCAL_INFILE option can be set with the mysql_optionsv() function:

/* enable local infile */
unsigned int enable_local_infile = 1;
mysql_optionsv(mysql, MYSQL_OPT_LOCAL_INFILE, (void *) &enable_local_infile);

If you are using MariaDB Connector/J, the allowLocalInfile parameter can be set for the connection:

Connection connection = DriverManager.getConnection("jdbc:mariadb://FULLY_QUALIFIED_DOMAIN_NAME:TCP_PORT/test?user=DATABASE_USER&password=DATABASE_PASSWORD&allowLocalInfile=true");

If you are using MariaDB Connector/Node.js, the permitLocalInfile parameter can be set for the connection:

mariadb.createConnection({
   host: 'FULLY_QUALIFIED_DOMAIN_NAME',
   port: 'TCP_PORT',
   user:'DATABASE_USER',
   password: 'DATABASE_PASSWORD',
   permitLocalInfile: 'true'
 });

If you are using MariaDB Connector/Python, the local_infile parameter can be set for the connection:

conn = mariadb.connect(
   user="DATABASE_USER",
   password="DATABASE_PASSWORD",
   host="FULLY_QUALIFIED_DOMAIN_NAME",
   port=TCP_PORT,
   local_infile=true)
