I'm writing a simple utility of merging few database dump files into a single one. I have a temporary database (lets name it 'db_temporary') and have to export it into the dump but in the dump file it should be named 'db_final'. Can I do this using 'mysqldump.exe'? This seems like a trivial task but I can't find any clue in the 'mysqldump' documentation here: https://dev.mysql.com/doc/refman/4.1/en/mysqldump.html
Big thanks to any help.
The Dump does not contain the database name, the dump only contains the tables and data from the database youve dumped. So yes, you could import the resulting SQL code in any Database you wish, just create a database and import the SQL code into that.
At least if you use it this form:
mysqldump.exe -u USERNAME -p database > database_dump.sql

I want to use mysqlsh to do the following:
Dump the FULL schema of a given database (not just tables, but functions, triggers, everything related to this database schema, same as mysqldump -R DATABASE > DATABASE.sql)
Load this full schema into a brand new database I just created (similar to mysql --database=NEWDATABASE < DATABASE.sql)
When I run mysqlsh --execute 'util.dumpTables("DATABASE", [], "SQL/DATABASE", {all:true});', it of course just dumps the tables, and this can easily be imported into a brand new database with this command mysqlsh --database=NEWDATABASE --execute 'util.loadDump("SQL/DATABASE", {schema: 'NEWDATABASE', ignoreVersion:true,resetProgress:true});. The problem is it is missing the functions and stored procedures.
So then I tried mysqlsh --execute 'util.dumpSchemas(["DATABASE"], "DATABASE");', and then load it into a new DB with mysqlsh --database=NEWDATABASE --execute 'util.loadDump("DATABASE", {dryRun: true, ignoreVersion:true});', but I instantly notice that it is trying to load into the original database, not my new database. So how do I load it into a NEW database, one with a totally different name?
In case you are wondering, I am trying to learn how to maximize mysqlsh for my use case. So the old mysqldump is not an option in this case.
I think you will just have to edit the .sql file(s) with a text editor before you try to load it.
This tool is really for dumping schemas and importing them to a different MySQL instance, but leaving the schema names unchanged.
How do I put these codes in MySQL workbench to create a logical backup of a BOOK table without using the command line? I put the codes below in the workbench and it shows an error: "mysqldump" is not valid at this position.
mysqldump [arguments] > file-name
mysqldump csit115 BOOK --user csit115 --password
--verbose --lock_tables > book.bak
Physical backups consist of raw copies of the directories and files that store database contents. This type of backup is suitable for large, important databases that need to be recovered quickly when problems occur.
Logical backups save information represented as logical database structure (CREATE DATABASE, CREATE TABLE statements) and content (INSERT statements or delimited-text files). This type of backup is suitable for smaller amounts of data where you might edit the data values or table structure, or recreate the data on a different machine architecture.
I have a data dump file(.sql) containing certain data, I would like to import it to my database(currently Sqlite3 but thinking about changing to MySQL) in order to use it in my test website.
Also, I need to know if it's possible to add the models too automatically, I presume it needs to be added manually, but any how, if there is any way to solve it, please suggest it.
There is a way to help you generate the Django models automatically given you have an existing database.
However this is a shortcut. You may then fine tune your models and add them to your app as needed.
Structuring your models in apps might force you to use the Models db_table meta option.
If at some point you would like to switch databases (Sqlite3 -> MySQL) you can export (dump) your current data to json. Then you could import (load) the data to the new database (after creating the database tables with migrate command). To do this you can use Django management commands:
Dump data
Load data
I was able to get an alternative answer after researching a bit.
Since I'm having a PostgreSQL data dump file with a file extension '.sql', I was capable of running a single command that imported the whole data dump into my local database, which is PostgreSQL. I'm using PgAdmin4 as my database management system and I installed psql during the installation of PgAdmin4, I added the psql to the path of my command prompt, hence it was accessible.
In order to import the data dump, I used the command provided below,
psql -U <username> -d <database_name> < <file.sql>
The '<' after database_name is necessary, so be sure to include it.
Here is the username of the configured account, is the database to which the data dump should be added, , is the file containing the data dump.
I have a SQL file with 22 MB(The Magento table - "index_event") , when i'm trying to import it to the MySQL database using MySQLWorkBench , WorkBench is not responding and hence i'm not able to import it.
Have tried to split the statements manually but few of the insert statements are very large and is hard to split as they were single statements.
Can anyone please suggest on how to tackle this situation?
Open a terminal and connect MySQL using below command.
mysql -u youruser -p
Now select your database in which you want to import schema and data.
use your_db_name;
Now Provide you sql file using below command.
source /home/user/yourdb.sql;
I did mysqldump for --all-databases and after some software updation on my machine the one database has deleted. so, How to restore that particular database form .sql file?
.sql file contain mysqump for all database.
pleased suggest something
When I've done this in the past I've used Workbench.
The SQL should contain the code to re-create the schemas and tables, along with the data.
