LOAD DATA INLINE

Overview

The LOAD DATA INLINE syntax imports strings organized in csv format into a data table, faster than INSERT INTO operations. The functionality of LOAD DATA INLINE is suitable for streaming fast data writes without a primary key, as in IoT class scenarios.

Syntax structure

mysql> LOAD DATA INLINE 
FORMAT='csv' ,
DATA=$XXX$
csv_string $XXX$
INTO TABLE tbl_name;

Parametric interpretation

FORMAT='csv' indicates that the string data in the following DATA is organized in csv format.

$XXX$ in DATA=$XXX$ csv_string $XXX$ is the identifier for the beginning and end of the data. csv_string is string data organized in csv format with \n or \r\n as a newline character.

Note

$XXX$ is the identifier for the beginning and end of the data, note that $XXX$ at the end of the data needs to be on the same line as the last line of data, a new line may cause ERROR 20101

Example: Importing data using LOAD DATA INLINE

  1. Start the MySQL client and connect to MatrixOne:

    mysql -h 127.0.0.1 -P 6001 -uroot -p111

    Note

    The login account in the above code section is the initial account. Please change the initial password promptly after logging into MatrixOne, see Password Management.

  2. Before executing LOAD DATA INLINE in MatrixOne, you need to create the completion data table user in MatrixOne in advance:

    CREATE TABLE `user` (
`name` VARCHAR(255) DEFAULT null,
`age` INT DEFAULT null,
`city` VARCHAR(255) DEFAULT null
)

  3. Perform a LOAD DATA INLINE on the MySQL client for data import, importing data in csv format:

    mysql> LOAD DATA INLINE 
FORMAT='csv',
DATA=$XXX$
Lihua,23,Shanghai
Bob,25,Beijing $XXX$ 
INTO TABLE user;
