MySQL

Test Tag Extra3

Extra Info zu Mysql: ist ein DB System

 

Mysql-Backup-Alle-DBs-auf-USB.cmd

 

@echo off

c:\xampp\mysql\bin\mysql.exe -u root -s -N -e "SHOW DATABASES" |   for /F "usebackq" %%D in (`findstr /V "information_schema performance_schema"`) do c:\xampp\mysql\bin\mysqldump.exe %%D -u root > f:\backups\%%D.sql

 

 

Mysql-Backup-Alle-DBs-auf-USB.vbs

Set WshShell = CreateObject("WScript.Shell")

WshShell.Run chr(34) & "C:\Mysql-Backup-Alle-DBs-auf-USB.cmd" & Chr(34), 0

Set WshShell = Nothing

Wenn man eine Query 10 mal wiederholen möchte, kann man so was verwenden:

Query 1:

 DELIMITER $$

 DROP PROCEDURE IF EXISTS mysql_loop_repeat_myprocedure1$$

 CREATE PROCEDURE mysql_loop_repeat_myprocedure1()

 BEGIN

 DECLARE x INT;

        

 SET x = 1;

        

 REPEAT

 INSERT INTO `users` ( `username` ) VALUES ( concat('BenutzerName', '-', (FLOOR(RAND() * 401) + 800)) );

Mysql Server startet nicht, bekomme diese Fehlermeldung:

/etc/init.d/mysql restart [....] Restarting mysql (via systemctl): mysql.serviceJob for mysql.service failed. See 'systemctl status mysql.service' and 'journalctl -xn' for details.

 

Was soll ich tun?
