MySQL存储过程报错 [err] 1366 - incorrect string value: '\xe7\x9f\xa5\xe8\xaf\x86...' for column 'v_name' at row 1

创建了类似以下的MySQL存储过程:

CREATE PROCEDURE test_procedure()
BEGIN
    DECLARE i int;
  DECLARE v_name VARCHAR(100);
  SET i = 0;
  WHILE i < 1024 DO
     SET v_name = CONCAT('中文字符_', i);
     INSERT INTO mytable(`name`,  parent_id,parent_name,ancestor_ids,`level`, create_uid, create_time, update_uid,update_time,`status`)
     VALUES (v_name,-1, '', '', 1, 2, '2020-11-30 14:44:29', 2, '2020-12-10 20:21:47', 1);
     SET i = i+1;
  END WHILE;
END;

插入中文字符,调用此存储过程时报错:

[err] 1366 - incorrect string value: '\xe7\x9f\xa5\xe8\xaf\x86...' for column 'v_name' at row 1

查看数据默认的字符编码:

> SHOW VARIABLES LIKE 'character%';
character_set_client    utf8
character_set_connection    utf8
character_set_database  latin1
character_set_filesystem    binary
character_set_results   utf8
character_set_server    utf8mb4
character_set_system    utf8
character_sets_dir  /usr/local/mysql/share/charsets/

原因是character_set_database默认是latin1。

方法一:修改character_set_database的值为utf8或者utf8mb4,然后重建存储过程。

方法二:在建表或者存储过程显示指定字符的编码。

DECLARE v_name VARCHAR(100) character set utf8;

重建存储过程,插入中文字符串成功。
