Important
You are viewing the documentation of an older version of the TiDB database (TiDB v3.0).
It is recommended that you use the latest LTS version of the TiDB database.
Import Example Database
Examples used in the TiDB manual use System Data from Capital Bikeshare, released under the Capital Bikeshare Data License Agreement.
Download all data files
The system data is available for download in .zip files organized per year. Downloading and extracting all files requires approximately 3GB of disk space. To download all files for years 2010-2017 using a bash script:
mkdir -p bikeshare-data &&
cd bikeshare-data &&
curl -L --remote-name-all https://s3.amazonaws.com/capitalbikeshare-data/{2010..2017}-capitalbikeshare-tripdata.zip &&
unzip \*-tripdata.zip
Load data into TiDB
The system data can be imported into TiDB using the following schema:
CREATE DATABASE bikeshare;
USE bikeshare;
CREATE TABLE trips (
trip_id bigint NOT NULL PRIMARY KEY AUTO_INCREMENT,
duration integer not null,
start_date datetime,
end_date datetime,
start_station_number integer,
start_station varchar(255),
end_station_number integer,
end_station varchar(255),
bike_number varchar(255),
member_type varchar(255)
);
You can import files individually using the example LOAD DATA
command here, or import all files using the bash loop below:
LOAD DATA LOCAL INFILE '2017Q1-capitalbikeshare-tripdata.csv' INTO TABLE trips
FIELDS TERMINATED BY ',' ENCLOSED BY '"'
LINES TERMINATED BY '\r\n'
IGNORE 1 LINES
(duration, start_date, end_date, start_station_number, start_station,
end_station_number, end_station, bike_number, member_type);
Import all files
Note
When you start the MySQL client, use the --local-infile=1
option.
To import all *.csv
files into TiDB in a bash loop:
for FILE in `ls *.csv`; do
echo "== $FILE =="
mysql bikeshare --local-infile=1 -e "LOAD DATA LOCAL INFILE '${FILE}' INTO TABLE trips FIELDS TERMINATED BY ',' ENCLOSED BY '\"' LINES TERMINATED BY '\r\n' IGNORE 1 LINES (duration, start_date, end_date, start_station_number, start_station, end_station_number, end_station, bike_number, member_type);"
done;
