How to easily import multiple sql files into a MySQL database?

In Windows, open a terminal, go to the content folder and write:

copy /b *.sql all_files.sql

This concate all files in only one, making it really quick to import with PhpMyAdmin.

In Linux and macOS, as @BlackCharly pointed out, this will do the trick:

cat *.sql  > .all_files.sql

Important Note: Doing it directly should go well, but it could end up with you stuck in a loop with a massive output file getting bigger and bigger due to the system adding the file to itself. To avoid it, two possible solutions.

A) Put the result in a separate directory to be safe (Thanks @mosh):

mkdir concatSqlcat *.sql  > ./concatSql/all_files.sql

B) Concat them in a file with a different extension and then change it the name. (Thanks @William Turrell)

cat *.sql  > all_files.sql1mv all_files.sql1 all_files.sql

This is the easiest way that I have found.

In Windows (powershell):

cat *.sql | C:\wamp64\bin\mysql\mysql5.7.21\bin\mysql.exe -u user -p database

You will need to insert the path to your WAMP - MySQL above, I have used my systems path.

In Linux (Bash):

cat *.sql | mysql -u user -p database

1. Goto cmd

2. Type in command promptC:\users\Usersname>cd [.sql tables folder path ]
   Press Enter
   Ex: C:\users\Usersname>cd E:\project\database

3. Type command prompt
   C:\users\Usersname>[.sql folder's drive (directory)name]
   Press Enter
   Ex: C:\users\Usersname>E:

4. Type command prompt for marge all .sql file(table) in a single file
   copy /b *.sql newdatabase.sql
   Press Enter
   EX: E:\project\database>copy /b *.sql newdatabase.sql

5. You can see Merge Multiple .sql(file) tables Files Into A Single File in your directory folder
   Ex: E:\project\database
