I just received an export from a MySQL database as a file mydb.sql. I installed MySQL in my Mac OS 10.10 laptop, put the .sql file in "/usr/local/mysql/data/", started the MySQL server. In R I installed the packages dplyr, RMySQL and their dependencies. I tried the dpylr function:
src_mysql(dbname = "mydb.sql")
as well as a few variations on this, but I get the error
Failed to connect to database: Error: Unknown database 'mydb'
What am I missing?
You have to create a database first, then import the data. Then the dplyr command works fine. This helped. If you are familiar with MySQL, this question probably annoyed you. R developers might find this more useful.

I am importing a mysql database from the webserver to my local system for a migration from drupal 6 to drupal 8.
I did an Export with phpmyadmin on the server. Then I created the database locally also with phpmyadmin and imported my dump from the server via phpmyadmin's import function.
Then I created the user with the setting of my drupal 6 configuration.
I can see the database in phpmyadmin if I connect with my local root user.
I cannot connect with the user created from the settings ( lets call that the drupal_db_user)
If I call the drupal site on my local apache ( apache & mysql server are running or my phpmyadmin would not work) I get the messeage from drupal:
"The mysqli error was: Unknown database 'my_drupal_db'."
Via Mysqlworkbench I am also not able to conntect to the my_drupal_db with the drupal_db_user.
I use locally php 5.6 and mysql 5.6 on a ubuntu system.
Creating the user and db via mysql console also did not help.
Any clue what might be wrong here? I suspect it could be the password encryption, but I have no clue how to check / change that other than trying the two options phpmyadmin (version 4.6) is offering me.
I guess you dont need to backup on your pc as the files that you exported from server is a backup on its own. Just download the sql file update to drupal 8 and finally import the file and you should have it installed.
Or simply try importing the exported file from server to another subdomain drupal 8 as a test. To check If it really works.
Found the problem.
after at least 3 hours poking around and cursing.....
When I created the database locally I had by mistake an whitespace in front of the db name.
Which by the way was possible... I didn't know you could even create databases with whitespaces in the name.
What let me find the error was this post:
https://drupal.stackexchange.com/questions/27050/fatal-error-pdoexception-sqlstate42000-1049-unknown-database
and the hint with this query:
SELECT * FROM my_drupal_db.users
which of course failed and made me really question the database name.
Hope that helps someone else saving 3 hours!
I would like to export a database from PHPMyAdmin (or MySQl Workbench) and import it to a SQLite database so that I can do local editing and testing without screwing up the live version. I am very new to SQL, so all of the export options, etc, are rather dense to me at this point. I have tried using the default export settings PHPMyAdmin with the command
sqlite3 test_db.db < maindb.sql
as well as
sqlite3--> .read maindb.sql
But these throw a bunch of syntax errors and 'no such table' errors.
I have also tried the oft-cited script script found here, but when I try to run this using an export from MySQL Workbench, using the command:
943776/mysql2sqlite.sh maindb.sql | sqlite3 test_db.sqlite
I get the following error:
mysqldump: Got error: 2002: Can't connect to local MySQL server through socket '/var/run/mysql.sock' (2) when trying to connect
Am I not configuring the exports correctly?
Please see that the referenced script connects to the database server itself. It does not expect a dump!
./mysql2sqlite -h example.com -u root -pMySecretPassWord myDbase | sqlite3 database.sqlite
This is the way the script should be executed. With host, username, passwort and the mysql database you would like to dump.
Since database dumps and DBMS features can be severely different between different DBMS (like MySQL and sqlite3), I would recommend to install a local MySQL server instead of using sqlite3. What advantage have you achieved when you make changes to sqlite3, which you cannot apply to the MySQL production database without changes?
An alternative solution is to export an sql dump of your database and then import it back into phpLiteAdmin. From there you can manage your sqlite database inside your browser. When you want to export it, just open the folder where the database is stored and copy the database file.
This solution does not require messing around with scripts, and it's especially handy if you're on a Mac and you're using MAMP, since phpLiteAdmin comes preinstalled with it.
Hi I'm trying to migrate a database that was created with cakePHP on a local MYSQL database. I know that in rails the solution is to install the postgres gem that will handle the migration, but I'm wondering more specifically about cakePHP.
I've generated a sqldump of the mysql database using the solution here:
http://book.cakephp.org/2.0/en/console-and-shells/schema-management-and-migrations.html
I've also installed postgres locally onto my machine and am able to connect to my remote empty HEROKU database from the command line by using heroku pg:psql
However, if I run the SQL dump file directly in the console I get an error called SSL SYSCALL error: Software caused connection abort. This apparently is because as a DEV / Free database account you are restricted from entering SQL commands directly.
So, that would suggest that I would have to go and use something like
heroku db:push localdatabase herokudatabase
But that produces the error Sequel::AdapterNotFound -> LoadError: 193: not a valid Win32 application
Any ideas how I might manage this migration, bearing in mind that as it's a CakePHP application I do not have the option of just installing a PostGres gem?
Thanks for any direction, or thoughts.
You almost certainly want to install Postgres locally on your machine, and get your database and code working correctly there. Once it's set up, it's easy to do a dump of your Postgres database and upload to Heroku.
To upgrade our application deployment platform from Windows to Ubuntu Linux Server, we need copy a MySQL InnoDB database from Windows to Linux server, and I tried 2 ways to do it:
1, use mysqldump tool to export to a sql and then import it from Linux server, this way got a lot of problems, like Chinese character garbage and InnoDB type tables are incorrect.
2, directly copy the database file (under mysql/data/) to Linux MySQL data folder (/var/lib/mysql/), and restart the MySQL, and by typing command lines, I can see the database we copied, and can see all the tables in the database, but when I type command line 'select * from sample_table', it shows error 'ERROR 1146 (42S02): Table 'sampleSchema.sample_table' doesn't exist', I know this table really exists. I don't why this happened.
So hope anybody knows this gives me help, thanks.
If you can access your Ubuntu Server remotely from your windows pc, you can use MySQL Workbench 5.2
Short version: I'm trying to figure out how to use the dsn argument in the odbcConnect() function to connect to a MySQL database.
Longer version: I appologize if this is an ignorant question. I didn't find an answer on SO searching under the tags. I'm not new to R, although I'm not the world's foremost expert. I am new to MySQL. I have been trying to learn it on my own.
I would like to be able to create tables and such in R and write them to a database in MySQL and then be able to select from them later and read the selected records back into R for analysis. I can create a database in MySQL, select, export a text file, & read that file into R now, but I would rather be able to do everything from R. For this purpose, I installed RODBC to be able to connect R to MySQL directly. I understand that I need to use the odbcConnect() function, but I do not understand what to put for the dsn argument to do this, and haven't been able to figure it out from the wiki or the help file.
Details (if needed):
I did not establish a uid or password when I set up MySQL
Versions used: Windows XP; R 2.10.1; MySQL 5.5
Locations of exe files: C:\Program Files\MySQL\MySQL Server 5.5\bin
C:\Program Files\R\R-2.10.1\bin
I expect I need fairly basic advice--e.g., it might be best to assume I don't even know what dsn stands for (even though that's not actually true). Any help is appreciated. Thanks in advance.
The simplest solution I can suggest would be installing RMySQL. This will give you native connectivity to the MySQL database that you are using.
If you want to use ODBC besides needing to have the MySQL ODBC drivers you will need to set up the ODBC connection in the ODBC manager on Windows XP. When you go through the connection it will ask you for a name, which will be your DSN name, which then you should be able to use in odbcConnect()
