Enable binary mode while restoring a Database from an SQL dump

Question

I am extremely new to MySQL and am running it on Windows. I am trying to restore a Database from a dumpfile in MySQL, but I get the following error:

$ >m         


        

Answer 1

Old but gold!

On MacOS (Catalina 10.15.7) it was a bit weird: I had to rename my dump.sql into dump.zip and after that, i had to use finder(!) to unzip it. in terminal, unzip dump.zip oder tar xfz dump.sql[or .gz .tar ...] leads to error msgs.

Finally, finder has unziped it totally fine, after that i could import the file without problems.

Answer 2

You can use this to fix error:

zcat {address_sql_database(.tar.gz)} | mysql -u root -p {database_name} --binary-mode

Answer 3

I meet the same problem in windows restoring a dump file. My dump file was created with windows powershell and mysqldump like:

mysqldump db > dump.sql

The problem comes from the default encoding of powershell is UTF16. To look deeper into this, we can use "file" utility of GNU, and there exists a windows version here.
The output of my dump file is:

Little-endian UTF-16 Unicode text, with very long lines, with CRLF line terminators.

Then a conversion of coding system is needed, and there are various software can do this. For example in emacs,

M-x set-buffer-file-coding-system

then input required coding system such as utf-8.

And in the future, for a better mysqldump result, use:

mysqldump <dbname> -r <filename>

and then the output is handled by mysqldump itself but not redirection of powershell.

Answer 4

Unzip the file, and then import again.

Answer 5

zcat /path/to/file.sql.gz | mysql -u 'root' -p your_database

Answer 6

Have you tried opening in notepad++ (or another editor) and converting/saving us to UTF-8?

See: notepad++ converting ansi encoded file to utf-8

Another option may be to use textwrangle to open and save the file as UTF-8: http://www.barebones.com/products/textwrangler/
