I have a database that I created using the CREATE DATABASE statement in the terminal and I have a .sql file full of statements creating tables and rows.
I just wanted to know what was the command line to execute that .sql on the database I created?
In the MySQL interactive client you can type:
source yourfile.sql
Alternatively you can pipe the data into mysql from the command line:
mysql < yourfile.sql
If the file doesn't specify a database then you will also need to add that:
mysql db_name < yourfile.sql
See the documentation for more details:
Executing SQL Statements from a Text File
If you have password for your dB then
mysql -u <username> -p <DBName> < yourfile.sql

I have a sql file that I want to upload from the command line. To do this I first need to go into MySQL and create the database
mysql> create database myDB;
and then call the following from the command line:
mysql -u username -p myDB < myDB.sql
Is there a way to do this all in one line from the command line?
I tried adding the following lines (and various combinations) to the beginning of the myDB.sql file:
create database `myDB`;
use `myDB`;
and then running
mysql -u username -p < myDB.sql
but that did not work.
ERROR 1046 (3D000) at line 7: No database selected
.sql files are generally LITERALLY just a sequence of SQL DDL/DML queries. If it was created by mysqldump, then it should contain EVERYTHING needed to recreate the database from the ground up, including the necessary create db and create table queries.
if they're not there, you can manually add them to the top of the file yourself via simple file concatenation/modification, e.g.
echo 'create database foo;' > new.sql
cat otherstuff.sql >> new.sql
mysql < new.sql
If you generated the mysqldump file with the --databases or --all-databases options, then it puts the correct CREATE DATABASE statements into the dump file.
This is a small question, but what is the name for a series of SQL/ DML / DDL commands stored in a file? Also, what is the syntax for running this file in DBMS?
The help command in mysql refers to it as a SQL script file. The syntax for running it in MySQL from the shell is:
mysql ..options.. < filename
e.g.
mysql -u username -p databasename < filename.sql
See the MySQL documentation for details of using the mysql command-line tool.
You can also run it from within the mysql command with:
mysql>source filename
or
mysql>. filename
I don't use phpMyAdmin, so I don't know if there's a way to do it from there.
Normally I have database already created. So this command line works find:
mysql -h -u -p [databaseName] < dump.sql
I have an import.sql file that has a top query that creates the database, if it doesn't already exist.
Is there a way to import the sql file, but without needing to select a pre-existing database?
Invoke the commandline without specifying the database
mysql -h -u -p < dump.sql
inside dump.sql, after you create the database add
USE databasename;
While creating the dump file using mysqldump you can use the switch --add-drop-database. This will include a statement to drop the database first. So in the subsequent statement, a fresh database will be created since no database with the given name exists

How can I populate a database from a sql file when I'm in the mysql console?
LOAD DATA INFILE doesn't fit my problem. I want to populate the whole database, not only one table. mysql -u root -p database < file.sql won't work either. Because I cannot out of the mysql console.
You want to bulk insert at commandline? Why not use mysqlimport
shell> mysqlimport [options] db_name textfile1 [textfile2 ...]
I don't know much about MySQL at all. But I am trying to reverse engineer a MySQL database using Visio. I know what steps I should take to do this, but I can't get my database to show in the 'Databases' section (as below):
How do I create the MySQL database using the .SQL file and get it to show up in this list? I have tried this code:
mysql -u username -p password database_name < filename.sql
using my own credentials of course. But that doesn't seem to work. In what folder should the .SQL file be placed if this statement is to work?
1) Create a file "filename.sql"
2) Create a database in your DB in which you want to import this file.
3) From command-prompt/terminal, move to the directory where you have created a "filename.sql".
4) Run the command: mysql -u username -p password database_name < filename.sql. (You can also give the proper path of your file and run this command from anywhere). It might be the case that you don't have a password set for MySQL. If so, mysql -u username database_name < filename.sql will also work.
In your case if you have created a database with name ojs and also created a file with name ojs.sql in C: drive then run the following command:
Edit: Put the path inside quotes.
mysql -u username -p password ojs < "C:\ojs.sql"
There is another way of importing tables in mysql. You can do it this way as well:
1) Connect your database
2) Type command "use ojs;"
3) Type command "source C:/ojs.sql"
Most MySQL SQL files that create databases create the database 'on-the-fly', so you typically needn't do anything except:
log-in
mysql -u [username] -p[password]
(Note: make sure you do NOT include a space (' ') character between the -p and the [password].
MySQL will think that [password] is the name of the database you want to connect to.
The 'general' log-in (above) does not assume you want to connect to any particular schema.)
source the file (do not use quotes around filename)
mysql> source [database_creation_file].sql
you can simply do it using mysql workbench
1> create a new query tab
2> CREATE DATABASE database_name;
3> USE database_name;
4> open the filename.sql file and execute it ctrl + shift + enter
5> all the tables in the filename.sql are created
To create a MySQL database using a SQL file, you can follow these steps:
Log in to your MySQL server using the mysql command-line tool and the appropriate credentials.
Use the CREATE DATABASE command to create a new database with the desired name:
CREATE DATABASE database_name;
Use the USE command to switch to the newly created database:
USE database_name;
Use the SOURCE command to import the SQL file into the database:
SOURCE path/to/sql/file;
The database will now be created and populated with the data from the SQL file. You can verify this by running some SQL queries against the database.
It's important to note that this process assumes that the SQL file contains valid SQL statements compatible with the version of MySQL you are using. If the SQL file contains any errors or unsupported statements, they will be displayed in the mysql command-line tool, and the import process will be interrupted.
