Batch-file for mysqldump to backup each database i

Question

Trying to create a batch (cmd) file for backing up each database into a separate file. Databases are created/deleted often, so batch file needs to grab current db names everytime it runs and backup each one of them.

Here is how I want it to be:

mysql -e "show databases" -u root --password=1234
mysqldump %dbname% -u root --password=1234 > S:\Backup\MySQL\%dbname%.sql

Is it possible to do in a batch file?

Please help. Thanks.

You are going to love this one

Have the information_schema database construct a DOS Batch File to perform the mysqldumps in parallel

set MYSQLUSER=root
set MYSQLPASS=1234
set BATCHFILE=S:\Backup\MySQL\Batch_mysqldump.bat 
set DUMPPATH=S:\Backup\MySQL
echo @echo off > %BATCHFILE% 
echo cd %DUMPPATH% >> %BATCHFILE% 
mysql -u%MYSQLUSER% -p%MYSQLPASS% -AN -e"SELECT CONCAT('start mysqldump -u%MYSQLUSER% -p%MYSQLPASS% --routines --triggers ',schema_name,' > ',schema_name,'.sql') FROM information_schema.schemata WHERE schema_name NOT IN ('information_schema','performance_schema')" >> %BATCHFILE% 
type %BATCHFILE% 

Just run like any DOS Batch File

Make sure you have the correct username and password to connect to mysql

I just tried it out to make sure

C:\>set MYSQLUSER=lwdba

C:\>set MYSQLPASS=<hidden>

C:\>set BATCHFILE=C:\LWDBA\Batch_mysqldump.bat

C:\>set DUMPPATH=C:\LWDBA

C:\>echo @echo off > %BATCHFILE%

C:\>echo cd %DUMPPATH% >> %BATCHFILE%

C:\>mysql -u%MYSQLUSER% -p%MYSQLPASS% -AN -Bse"SELECT CONCAT('start mysqldump -u%MYSQLUSER% -p%MYSQLPASS% --routines --triggers ',schema_nam
e,' > ',schema_name,'.sql') FROM information_schema.schemata WHERE schema_name NOT IN ('information_schema','performance_schema')" >> %BATCH
FILE%

Answer 2

I've tried the answers but none of them worked as expected, here is my solution for backup but it will create a single file for mysql and other user databases.

set USERNAME=root
set PASSWORD=1234
set TIMESTAMP=%DATE:~10,4%.%DATE:~4,2%.%DATE:~7,2%-%TIME:~0,2%.%TIME:~3,2%.%TIME:~6,2%
set BACKUPPATH=D:\Backup\MySql\

if not exist %BACKUPPATH% md %BACKUPPATH%

mysqldump --all-databases --result-file="%BACKUPPATH%%TIMESTAMP%.sql" --user=%USERNAME% --password=%PASSWORD%
