    • sudo find / -iname mysqldump for Mac Os mac.png or Linux Os linux.png
    • If you installed
      • XAMPP for Mac Os mac.png : Entire path is /Applications/XAMPP/xamppfiles/bin/mysqldump
      • XAMPP on X disk for Win Os windows.png : Entire path is X:\xampp\mysql\bin\mysqldump.exe
      • MAMP & MAMP PRO for Mac Os mac.png : Entire path is /Applications/MAMP/Library/bin/mysqldump
  2. input the complete path of mysqldump command
    • old command which caused error mysqldump -h 127.0.0.1 -u root -p --force --single-transaction DATABASE_NAME | pv | gzip -c > DATABASE_NAME.sql.gz
    • new command /Applications/XAMPP/xamppfiles/bin/mysqldump -h 127.0.0.1 -u root -p --force --single-transaction DATABASE_NAME | pv | gzip -c > DATABASE_NAME.sql.gz

could not access the mysql log[edit]

Version: XAMPP 5.6.15-1 on Mac Os mac.png

Cause:

  • the error log only be accessed by the user named mysql[1]

Solution [2]:

find the path to the mysql log
$ ls /Applications/XAMPP/xamppfiles/var/mysql/*.local.err

find the file name of mysql log ex: XXXMacBook-Pro.local.err

set the permission of log
$ sudo chmod 774 /Applications/XAMPP/xamppfiles/var/mysql/XXXMacBook-Pro.local.err

Could not open single-table tablespace file filename.ibd[edit]

Version: XAMPP 5.6.15-1 on Mac Os mac.png

Condition: The Mac was shutdown accidentally and the database was not shutdown normally. After reboot the Mac, unable to start the MySQL service[3][4].

Possible solution:

  1. Edit the MySQL configuration file located: /Applications/XAMPP/xamppfiles/etc/my.cnf
  2. Add this line: innodb_force_recovery = 1
  3. Try to start the MySQL service
  4. If the MySQL service started successfully, edit the MySQL configuration file and mark this line : #innodb_force_recovery = 1
  5. Restart the MySQL service


Could not start MySQL service on Windows[edit]

Solution:

  1. check the column name 'xxx' if exists
  2. if the column name 'xxx' was computed by the User-Defined Variables. Enclosed the whole query into another parent derived query.
-- The query which met the error message: [Err] 1054 - Unknown column 'rank' in 'where clause'
SELECT semi.*, IF(semi.id = semi.prev, @rank := @rank +1, @rank := 1 ) AS `rank`   
FROM
(
        ...
) semi
WHERE semi.rank <= 10

Enclosed the whole query into another parent derived query.

ERROR 1206: The total number of locks exceeds the lock table size[edit]

Message: Error Code: 1206. The total number of locks exceeds the lock table size

Current condition[25]:

  • Keywin SHOW VARIABLES LIKE 'innodb_buffer_pool_size';. If it returns 8388608, it means 8388608 bytes ≅ 8MB.

Solution:

  • Increase innodb_buffer_pool_size e.g. SET GLOBAL innodb_buffer_pool_size=402653184; (402653184 bytes ~ 400MB. Default value is 8MB.)
  • Reduce the size of query data

ERROR 1827 (HY000): The password hash doesn't have the expected format. Check if the correct password algorithm is being used with the PASSWORD() function.[edit]

Wrong sql query as follows:

CREATE USER 'test'@'localhost' IDENTIFIED BY PASSWORD 'my_password';

Solution: (1) Check if the account was created or not

SELECT User,Host FROM mysql.user;

(2a) If the account was created, set the password for the account.

SET PASSWORD FOR 'test'@'localhost' = PASSWORD('my_password');

(2b) If the account was NOT created, re-create the account.

CREATE USER 'test'@'localhost' IDENTIFIED BY 'my_password';

ERROR 2013: Lost connection to MySQL server during query[edit]

Message: Error Code: 2013. Lost connection to MySQL server during query

Condition: After executed the following query contains number of rows which exceed 1,000,000 rows, I met the error message 'Error Code: 2013. Lost connection to MySQL server during query'.

INSERT IGNORE INTO `target`.`table` SELECT * FROM `source`.`table`;

Solution:

  • Increase the settings of (1) DBMS connection keep-alive interval (in seconds) & (2) DBMS connection read time out (in seconds) on MySQL Workbench [31][32]. And remember to restart the MySQL Workbench after the settings were modified. e.g. The default setting of DBMS connection read time out (in seconds) is 30 seconds, you may increase to 6000 seconds (100 minutes).
  • Reduce the number of rows to reduce the execution time (1) by using LIMIT clause (2) or by splitting the query size e.g. MOD(column, 2) = 0 & MOD(column, 2) > 0 if the column is numeric.
INSERT IGNORE INTO `target`.`table` SELECT * FROM `source`.`table` LIMIT 0, 10000;
