我无法在 Mysql 5.7 中将 .json 文件作为表导入;所有行保持空白。我不确定错误在哪里。
我正在使用存储在 /home/name/json_data/sample.json
下的以下 json 文件
{
"price": null,
"sale_list": [
{
"buyer": "SmackMe089",
"date": "April 29th 2019 21:20:50",
"id": "1234",
"item_desc": ""
}
}
当我尝试使用以下命令将其导入 mysql 5.7 sql
时文件没有被导入。
文件.sql:
CREATE TABLE example_table (
id INT NOT NULL AUTO_INCREMENT,
json_data JSON NOT NULL,
PRIMARY KEY (id)
);
LOAD DATA INFILE '/home/path/json_data/sample.json' INTO TABLE example_table (json_data);
尝试导入到mysql:
mysql --host=host_ip -u root -p db_name < /home/path/data/file.sql
最佳答案
有几个选项:
测试:
$ mysql

MySQL Shell:正如 @TimBiegeleisen 所说,您可以使用 MySQL Shell (即使使用 MySQL 5.7),但您必须激活 X Plugin :
$ mysqlsh --sql
