Moving and Backing Up a Large MySQL Database

由 痴心易碎 提交于 2019-12-08 07:55:04
问题 I'm using MySQL Workbench and I've built a very large (17 GB) database. MySQL puts the data in a single file called ibdata1 in the C:\ProgramData\MySQL\MySQL Server 5.5\data directory. I'm out of space on my C drive and I would like to move it to my external drive. Is it possible to move that ibdata1 file and then tell MySQL to point to another location to find it? Also, if I want to back up that data, can I just copy the ibdata1 file and save it. And then if my computer were stolen or

问题 I want to prevent user from using deleting * from table unless primary key specified, one of our team member accendently used "delete * from table_name" i want to prevent such scenarios in future. 回答1: Would safe updates be viable for you? This is an option you can enable on the command line, in the option file or set a variable in SQL code that prevents updates and deletes without a where clause that includes the key columns defining the rows to change.

问题 I just started getting this Error today while using MySQL workbench, and noticed it showing up in my application as far back as saturday. Anyone else getting it? Have any idea what might be causing it? ERROR Error Code: 1290. The MySQL server is running with the --read-only option so it cannot execute this statement Running just a simple insert generates the error. Eg.. INSERT INTO Job1111 .

How do I automatically execute a MySQL script or routine after forward engineering from model

由 痴心易碎 提交于 2019-12-07 06:54:05
问题 I've built a EER Model in MySQL Workbench that I forward engineer to create the database. The forward engineering works perfectly, and the database is created from the diagram as expected. Apart from tables, there are also some Stored Procedures (aka Routines) that I've included in the model. These routines are designed to only be run once, as soon as the database has been set up. They automatically insert necessary data into the tables. My question is, how can I get the forward engineering

MySQL Workbench: Unable to see text

由 大憨熊 提交于 2019-12-07 06:27:19
问题 My installation of MySQL Workbench is rather unusable because of the font/background colours. Initially I assumed that this was due to the Light/Dark theme on Mac OSX Mojave, but I have switched between both and it still remains the same. The problem has only started since I upgraded to Mac OSX Mojave. Is there anything I can do to make things more visible? Edit: My currently selected theme is the 'Light Theme' 回答1: MySQL Workbench 8.0.13 doesn't support the new dark mode of macOS Mojave yet.

MySQL Workbench Inserts

问题 I am using MySQL Workbench 5.2.28 for designing my database schema. I need to insert default data into some tables which can be done using the "Inserts" tab. However, it seems like it only allows entering data manually, one row at a time. I have an OUTFILE with several hundred rows that I would like to insert. Is this possible with MySQL Workbench? Would creating separate MySQL scripts for importing default data be a better approach? 回答1: I am now using separate sql scripts for inserting my
