Trying to import a MySQL database using PHP-Admin. When I try to import the file backed-up by my host, I get this error message:
SQL query:
DROP TABLE IF EXISTS `wp_commentmeta`
MySQL said: Documentation
#1046 - No database selected
I have also tried to export the database myself, then trying to import that specific file. When I do that, however, I get a completely different error message:
SQL query:
CREATE TABLE IF NOT EXISTS `wp_commentmeta` (
`meta_id` bigint(20) unsigned NOT NULL,
`comment_id` bigint(20) unsigned NOT NULL DEFAULT '0',
`meta_key` varchar(255) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
`meta_value` longtext COLLATE utf8mb4_unicode_ci
) ENGINE=MyISAM DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci

What can I do to resolve this?
You need to USE a database. You could edit your file and add the line at the top, something like:
USE databasename;
Some tools will let you set a default database when restoring from backup. If you haven't selected one that could be a problem.
If you haven't created a database you'll need to do that first.
You need to select which database you are importing to in your SQL. Your first statement should be:
USE DATABASE `db_name`;
You have no database selected.
Find which databases exist
SHOW DATABASES:
and then select one for use
USE `database_name`
You say that you are importing into a new host, so I would assume that you do not already have a database created;
CREATE DATABASE `database_name`
Now you can USE that database you just created; and your queries should now work.

According to MariaDB's website, you can simply replace MySQL with MariaDB.
Great, I thought, however after installing MariaDB (10.5.7), some of my InnoDB tables are corrupt. The error is Unknown data type "MYSQL_JSON".
One of the corrupt tables also says "in use" in phpmyadmin, and I can't access it at all.
So, I was looking for a solution everywhere, and apparently MariaDB doesn't support that type. Is there any way to fix that? There must be some way to covert those columns, right?
I tried to downgrade back to MySQL 5.7, but now MySQL isn't working anymore, so I reinstalled MariaDB again. I couldn't find any downgrade guide either.
Here's a create table statement for the corrupt table, made from my local test-database. I was able to mysqldump all the other ones successfully. Just not this one. Granted, I have a backup from 1 day ago, but losing work from a whole day is not a nice thing regardless.
CREATE TABLE `news` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`author_id` int(10) unsigned DEFAULT NULL,
`title` varchar(180) COLLATE utf8mb4_unicode_ci NOT NULL,
`content` longtext COLLATE utf8mb4_unicode_ci DEFAULT NULL,
`excerpt` varchar(255) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
`sources` longtext COLLATE utf8mb4_unicode_ci DEFAULT NULL COMMENT '(DC2Type:json)',
`header` varchar(30) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
`copyright` varchar(255) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
`category` smallint(5) unsigned DEFAULT NULL,
`featured` tinyint(1) NOT NULL,
`language` smallint(5) unsigned NOT NULL,
`published` datetime DEFAULT NULL,
`status` smallint(5) unsigned NOT NULL,
PRIMARY KEY (`id`),
KEY `IDX_1DD39950F675F31B` (`author_id`),
CONSTRAINT `FK_1DD39950F675F31B` FOREIGN KEY (`author_id`) REFERENCES `user` (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=167 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci
The table is auto-generated by Doctrine ORM.
If I could somehow get just a few rows of data out of that table, that would make my week. I just need the content column from the last day.
I got my system back running from my backup. Just those news are missing.
Update
I was able to find a .ibd file under /var/lib/mysql/{mydatabase}/ which contains all the data I needed in plain text. I'm just manually copying the content and insert it back into the database.
To fix Unknown data type "MYSQL_JSON" in the general case when migrating from MySQL to MariaDB.
You have 2 options.
Dump your database from MySQL and import it to MariaDB.
Fix all tables that have a JSON type column.
The first option is straightforward but to go with the second option as suggested by MariaDB website.
stop MySQL service if it is running
sudo service mysql stop
start a new mysql server instance
mysqld --no-defaults --datadir=<Your data dir directory> --lc-messages_dir=./share --plugin-dir=<path to directory containing type_mysql_json.so> --plugin-maturity=alpha
default datadir directory (mysql 5.7, ubuntu 18.04) is /var/lib/mysql/
default plugin directory is /usr/lib/mysql/plugin
while keeping the server running start a new MySQL command-line client and install mysql_json plugin.
install soname 'type_mysql_json';
Alter all tables that have a JSON type column.
ALTER TABLE `database_name`.`table_name` FORCE;
stop MySQL server instance and start MySQL service and everything should be fine.
ps: If you have lots of tables that contains JSON type column (as in my case) you can use this command to get list of all commands you have to run in order to fix all tables
SELECT CONCAT("ALTER TABLE `", TABLE_SCHEMA,"`.`", TABLE_NAME, "` FORCE;") AS MySQLCMD FROM TABLES WHERE TABLE_SCHEMA = "<YOUR_DATABASE_NAME>";
An in-place upgrade of the mysql-5.7 to MariaDB, for the JSON type requires a plugin to read its data format:
Add the following to your MariaDB server configuration:
plugin_load_add=mysql_json=type_mysql_json
plugin_maturity=alpha
Run mysql_upgrade --force to pick up all the JSON data types and convert them.
Alternately just ALTER TABLE news FORCE to change that one table.
I have a project sent to me by a friend and i am having serious issues importing the database into my WAMP Server. I end up getting Mysql error

#1046 - No database selected
Firstly you have to create database manually or select the existing one in phpmyadmin (as mentioned WAMP server is used ) and then import the .sql file in it, and the database name should be same as that of used in application else will not work with desired application to which the database is linked.
It's not really a big deal! The message itself is self-explanatory. You need to select an existing database first & then try your import.
Or you could possibly add the following at the very top of your DB script that you trying to import -
CREATE DATABASE IF NOT EXISTS drivers_endorsements;
USE drivers_endorsements;
I have looked on stackoverflow and the mysql and Plantmysql forums
Nobody has quite been able to answer this.
Steps
I created a CSV from an Excel file
Imported using the Table Data Import Wizard in MySQL
I am able to run
SELECT * FROM apporteur_mapping_table;
However I get Error Code 1054 when I run
SELECT broker_code FROM apporteur_mapping_table;
Field type is VARCHAR(20)
Update #2 - output from SHOW Create Table
CREATE TABLE `apporteur_mapping_table` (
`broker_code` varchar(20) COLLATE utf8_unicode_ci DEFAULT NULL,
`broker_name` text COLLATE utf8_unicode_ci,
`date_de_creation_de_code` text COLLATE utf8_unicode_ci,

I seem to have been able to resolve it by Creating the table in code from scratch. It seems using the Table Data Import Wizard in mysql caused the data to have some interpretation
I am using MySQL Workbench 6.3 on Windows 10
Annotation can be found here

Anyone able to help?
I downloaded a MySQL backup file and promptly imported into MAMP's phpMyAdmin. I got this

I did not alter the .sql file at all. Any hints on how i can get this puppy going locally?
Thanks!
Just create a database with some name first of all. Click on that database and then import your table. The problem here is when you import any table it looks for which database you are using. So, either do as I said above or add this just above CREATE TABLE IF NOT EXISTS columns_priv (
USE your_db_name;//here your_db_name is the database you just created.
That's it.
In phpMyAdmin make a new database or select a existed database. Then import the SQL file.
Normally Exported sql Script does not have create database syntax. So you should create a database and use manually
or
Include below lines into your first line of the sql script.
create database database_name;
use database_name;
Note : If database already exists then you only include second statement.
Now you can import without Error.
Create the database and in the sql file that you are importing add this
USE db_name;
You need to create and/or select the database on your sandbox machine before importing the SQL for the table structure and data.
In phpMyAdmin, this means choosing a database from the sidebar and then using its import tab. If the database you want to fill doesn't exist, you have to create it first using the Create new database form.
After import, you should confirm that the export-import process hasn't affected the anonymous user record (uid 0).
Credits to #scronide
If the DB is exported from sql with phpmyadmin, you should use custom method. And chose
include a timestamp of when databases were created,last updated,and
last checked
this sql will contains
create database database_name; use database_name;
you just have to use USE db_name; at the starting of Sql code file which you exported and the problem will be resolved
I am using the Zymic Database Uploader v1.1 to upload my XAMPP/MySQL database to zymic database.
I followed the instruction carefully until I got this error.
Error at the line 27: ) ENGINE=MEMORY DEFAULT CHARSET=latin1 COLLATE=latin1_general_ci MAX_ROWS=15000;
Query: CREATE TABLE `bmf_chatting` (
`usr_id` int(11) NOT NULL,

`timestamp` int(11) NOT NULL
) ENGINE=MEMORY DEFAULT CHARSET=latin1 COLLATE=latin1_general_ci MAX_ROWS=15000;
MySQL: Table 'bmf_chatting' already exists
This happened while I was Processing/Importing the database into Zymic but it stopped on error. I have no database yet in my zymic and I have no duplicate table 'bmf_chatting'.
I thought it will be a simple export/import. :(
Check your dump file, if this table didn't get exported twice for whatever reason.
Also make sure, to drop all tables (and maybe the entire database) before you retry with you import. Whatever tables are created above this one, have already been created.
It sounds like you had a table called bmf_chatting in MySQL before and it was improperly deleted (the files were probably deleted without dropping the database).
Try running a drop database query before your create query.
