I have a custom wordpress table(my_table). And i am inserting,updating all that good stuff to it. When i try to use
$wpdb->get_results("SELECT * FROM $wpdb->my_table",ARRAY_A);
or
$wpdb->get_results("SELECT * FROM my_table",ARRAY_A);
I get this error
WordPress database error: [Table 'mydatabase.my_table' doesn't exist]
SELECT * FROM my_table
I have tried to add my_table to wp-db.php as well but i still receive this error.
Yes the table is in the database
There is data in the table
Is their a config option of i need to change or somewhere else where i need to add my table name? I cannot find it for some reason.
full error
WordPress database error Table 'mydatabase.mytable' doesn't exist for query SELECT * FROM mytable made by do_action, call_user_func_array, promos
Ok tiggles, here is what I would do in your situation if you are still stuck. Create a new table, but this time, by executing a SQL command from WordPress, using something like :
$wpdb->query('CREATE TABLE mynewtable (First_Name char(50), Last_Name char(50), ... etc.)');
Immediately check that you can query it. If so, then go to your databse and dump all data from mytable into this newly created table. Use this one instead.
If it was a user permission because the user that created the previous table was not the same as the one granted access to as WordPress, then you will be safe.
If your table my_table is, indeed, in the mydatabase database and if mydatabase is, indeed, WordPress' database, there is no reason why it should not work. If mydatabase is not WordPress database or if my_table is in another database, then it is normal that it does not work.

need some help here.
You need to tell MySQL which database to use:
USE database_name;
before you create a table.
In case the database does not exist, you need to create it as:
CREATE DATABASE database_name;
followed by:
USE database_name;
You can also tell MySQL what database to use (if you have it created already):
mysql -u example_user -p --database=example < ./example.sql
I faced the same error when I tried to import a database created from before. Here is what I did to fix this issue:
1- Create new database
2- Use it by use command
3- Try again
This works for me.
If you're trying to do this via the command line...
If you're trying to run the CREATE TABLE statement from the command line interface, you need to specify the database you're working in before executing the query:
USE your_database;
Here's the documentation.
If you're trying to do this via MySQL Workbench...
...you need to select the appropriate database/catalog in the drop down menu found above the :Object Browser: tab. You can specify the default schema/database/catalog for the connection - click the "Manage Connections" options under the SQL Development heading of the Workbench splash screen.
Addendum
This all assumes there's a database you want to create the table inside of - if not, you need to create the database before anything else:
CREATE DATABASE your_database;
If you are doing this through phpMyAdmin:
I'm assuming you already Created a new MySQL Database on Live Site (by live site I mean the company your hosting with (in my case Bluehost)).
Go to phpMyAdmin on live site - log in to the database you just created.
Now IMPORTANT! Before clicking the "import" option on the top bar, select your database on the left side of the page (grey bar, on the top has PHP Myadmin written, below it two options:information_schema and name of database you just logged into.
once you click the database you just created/logged into it will show you that database and then click the import option.
That did the trick for me. Really hope that helps
For MySQL Workbench
Select database from Schemas tab by right mouse clicking.
Set database as Default Schema
Edit your SQL file using Notepad or Notepad++
add the following 2 line:
CREATE DATABASE NAME;
USE NAME;
Assuming you are using the command line:
1. Find Database
show databases;
2. Select a database from the list
e.g. USE classicmodels; and you should be off to the races! (Obviously, you'll have to use the correctly named database in your list.
Why is this error occurring?
Mysql requires you to select the particular database you are working on. I presume it is a design decision they made: it avoids a lot of potential problems: e.g. it is entirely possible, for you to use the same table names across multiple databases e.g. a users table. In order to avoid these types of issues, they probably thought: "let's make users select the database they want".
If importing a database, you need to create one first with the same name, then select it and then IMPORT the existing database to it.
Hope it works for you!
be careful about blank passwords
mysqldump [options] -p '' --databases database_name
will ask for a password and complain with mysqldump: Got error: 1046: "No database selected" when selecting the database
the problem is that the -p option requires that there be no space between -p and the password.
mysqldump [options] -p'' --databases database_name
solved the problem (quotes are not needed anymore).
Check you have created the database first which you want.
If you have not created the dataBase you have to fire this query:
CREATE DATABASE data_base_name
If you have already created the database then you can simply fire this query and you will be able to create table on your database:
CREATE TABLE `data_base_name`.`table_name` (
_id int not null,
LastName varchar(255) NOT NULL,
FirstName varchar(255),
Age int,
PRIMARY KEY (_id)
);
Solution with an Example
Error 1046 occurs when we miss to connect our table with a database. In this case, we don't have any database and that’s why at first we will create a new database and then will instruct to use that database for the created table.
# At first you have to create Database
CREATE DATABASE student_sql;
# Next, specify the database to use
USE student_sql;
# Demo: create a table
CREATE TABLE student_table(
student_id INT PRIMARY KEY,
name VARCHAR(20),
major VARCHAR(20)
);
# Describe the table
describe student_table;

"If importing a database, you need to create one first with the same name, then select it and then IMPORT the existing database to it.
Hope it works for you!"
These are the steps:
Create a Database, for instance my_db1, utf8_general_ci.
Then click to go inside this database.
Then click "import", and select the database: my_db1.sql
That should be all.
first select database : USE db_name
then creat table:CREATE TABLE tb_name
(
id int,
name varchar(255),
salary int,
city varchar(255)
);

I'm late i think :] soory,
If you are here like me searching for the solution when this error occurs with mysqldump instead of mysql, try this solution that i found on a german website out there by chance, so i wanted to share with homeless people who got headaches like me.
So the problem occurs because the lack -databases parameter before the database name
So your command must look like this:
mysqldump -pdbpass -udbuser --databases dbname
Another cause of the problem in my case was that i'm developping on local and the root user doesn't have a password, so in this case you must use --password= instead of -pdbpass, so my final command was:
mysqldump -udbuser --password= --databases dbname

In Amazon RDS, merely writing use my-favorite-database does not work if that database's name includes dashes. Furthermore, none of the following work, either:
use "my-favorite-database"
use `my-favorite-database`
use 'my-favorite-database'
Just click the "Change Database" button, select the desired database, and voilà.
Although this is a pretty old thread, I just found something out. I created a new database, then added a user, and finally went to use phpMyAdmin to upload the .sql file. total failure. The system doesn't recognize which DB I'm aiming at...
When I start fresh WITHOUT first attaching a new user, and then perform the same phpMyAdmin import, it works fine.
Just wanted to add: If you create a database in mySQL on a live site, then go into PHPMyAdmin and the database isn't showing up - logout of cPanel then log back in, open PHPMyAdmin, and it should be there now.
For an added element of safety, when working with multiple DBs in the same script you can specify the DB in the query, e.g. "create table my_awesome_db.really_cool_table...".
jst create a new DB in mysql.Select that new DB.(if you r using mysql phpmyadmin now on the top it'l be like 'Server:...* >> Database ).Now go to import tab select file.Import!

I wrote a spreadsheet to SQL query converter just now in JavaScript. The converter works fine, here is an example of what it spits out:
CREATE TABLE something(column1 varchar(3000),column2 varchar(3000),column3 varchar(3000));
INSERT INTO something VALUES(a1,a2,a3);
INSERT INTO something VALUES(b1,b2,b3);
INSERT INTO something VALUES(c1,c2,c3);
As far as I can tell, that is a valid SQL query (but maybe I'm wrong...). When I copy and paste this query into the 'SQL' tab in the MySQL database I created, I get this error message:
#1046 - No database selected
I thought perhaps it needed the name of the database (excel), so I tried adding the name of the database like so:
CREATE TABLE excel.something(column1 varchar(3000),column2 varchar(3000),column3 varchar(3000));
INSERT INTO something VALUES(a1,a2,a3);
INSERT INTO something VALUES(b1,b2,b3);
INSERT INTO something VALUES(c1,c2,c3);
and I get this:
#1142 - CREATE command denied to user '(my SQL information was here but I removed it)' for table 'something'
What is it that I'm missing? I've run other queries directly in MySQL before without issue, but I can't seem to run this CREATE query. Worst case scenario, I could manually create the table before hand, but that defeats the purpose of automating the process...
Insert use something; before your query.
And for your denied access problem do this:
GRANT ALL ON something TO user#'%' IDENTIFIED BY 'password';
FLUSH PRIVILEGES;
I am new to building databases, i have created a database for a website i am creating, and i keep getting this message "Executing SQL script in server
ERROR: Error 1146: Table 'mydb.franch' doesn't exist", when trying to forward engineer my database. The table does exist but it is not being read. (See image below). Please any help will be appreciated.
I can't add a comment, but in your image the table is "Franch" not "franch". Maybe that is the problem?
I may be wrong but I believe you are trying to access your table as (something like)
select * from 'mydb.franch'
or
select * from `mydb.franch`
In either case it's wrong and should be
select * from `mydb`.`franch`
MYSQL is case sensitive when creating a table, which means that you cannot create a table or variable with lower/upper case, and call it with upper/lower cases.
As such you must call the same name you used to create the table. In this case since the table is called mydb.Franch you would do: select * frommydb.Franch;`
Is there a way to insert data from a table in schema1 to a table in schema2 in mysql.
Also , I assume there will be any access/privilege issues.
My environment is Joomla using Fabrik extension, PHP, MySQL
Kindly share some tips
Thanks in advance
This query does that:
INSERT INTO db2.table1 SELECT * FROM db1.table1;
Not tested but should do the job.
If you do this as root user, you will have no permission issues.
Backup your data first, though.
You can always preface the table name with the database name and as long as the user has the appropriate permission you can do:
insert into db1.users( first, middle, last )
select a.first, a.middle, a.last from db2.users a
See the following for the documentation insert .. select
