Database Import error after exporting

Question

Just like title say. I am using HeidiSQL, and i wan't to duplicate a database so i export the database, create a new empty with name "test". Then i change the name of the database to "test" in the .sql file and try to import the database, then i recieve this error

Error de SQL (1064): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right

syntax to use near '--

-- Host: ' at line 1

I think is something about the first part of the sql file, which is

-- --------------------------------------------------------
-- Host:                         
-- Versión del servidor:         5.5.41 - MySQL Community Server (GPL) by Remi
-- SO del servidor:              Linux
-- HeidiSQL Versión:             9.1.0.4867
-- --------------------------------------------------------

As far as i know its supposed to be only just comments.

Any suggestion?

Thanks in advance and sorry if its an idiot question but don't know how to solve this, i searched without results. Sorry if my english is not perfect too.

UPDATE: first 100 lines of the file

Answer 1

In my case the solution was to change character set in sql file. Open your database .sql file and replace /*!40101 SET NAMES utf8mb4 */; to /*!40101 SET NAMES utf8 */; .

Answer 2

You should select the right file encoding when you load any SQL file in HeidiSQL. The auto-detection of the file encoding was often enough prone to errors. I already tried several approaches in the HeidiSQL code for fixing the detection but there seem to be a myriad of files outside which are not detected correctly.

In your case, I assume the "Auto detect" setting in the file-open dialog probably misdetected an encoding which must have a BOM (2 to 4 bytes) at the very start of the file.

So, when you open a .sql file in HeidiSQL, avoid selecting "Auto detect (may fail)" in the "Encoding" dropdown box.
