Overview

MariaDB Enterprise Server users can import data into a database using the LOAD DATA LOCAL INFILE 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

Compatibility

Import Schema

Determine the connection parameters for your MariaDB Enterprise Server database.
Use MariaDB Client with the connection information to import your schema into your MariaDB Enterprise Server database:
```
$ mariadb --host FULLY_QUALIFIED_DOMAIN_NAME --port TCP_PORT \
      --user DATABASE_USER --password \
      --ssl-verify-server-cert \
      --ssl-ca ~/PATH_TO_PEM_FILE \
      --default-character-set=utf8 \
      < mariadb_schema.sql
```
- Replace FULLY_QUALIFIED_DOMAIN_NAME with the IP address or Fully Qualified Domain Name of your database
- Replace TCP_PORT with the TCP port of your database
- Replace DATABASE_USER with the username for your database user account
- If TLS is required, replace ~/PATH_TO_PEM_FILE with the path to the certificate authority chain (.pem) file
After the command is executed, you will be prompted for the password of your database user account.

Import Data

Determine the connection parameters for your MariaDB Enterprise Server database.
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 \
      --ssl-ca ~/PATH_TO_PEM_FILE \
      --default-character-set=utf8 \
      --local-infile
```
- Replace FULLY_QUALIFIED_DOMAIN_NAME with the IP address or Fully Qualified Domain Name of your database
- Replace TCP_PORT with the TCP port of your database
- Replace DATABASE_USER with the username for your database user account
- If TLS is required, replace ~/PATH_TO_PEM_FILE with the path to the certificate authority chain (.pem) file
After the command is executed, you will be prompted for the password of your database user account.
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 Enterprise Server database.

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 ',';
```

MariaDB Connectors

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

The section above mentions that mariadb client requires the --local-infile option to be specified.

If you are using a MariaDB Connector instead of the mariadb client, then you must use a different method to enable support for the LOAD DATA LOCAL INFILE statement.

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)
