![]() ![]() Please note that it's not possible to apply this, before you cleaned up your database, as the foreign keys do not exist. If you do have feedback, please let us know how this affects your setup. Enter the password and execute the SHOW DATABASES command we have discussed above.

First, you have to log in using your username and password before you issue show databases command on cmd. This is not enabled by default, because we're not sure what the consequences are from a performance point of view. Open the Command Prompt and navigate to the bin folder of your MySQL Server installation directory. This will make sure that no records, comments or keys exists for domains that you already removed. * Using this SQL causes Mysql to create foreign keys on your database. Cryptographic software and export control.In which one of the 26 universes does Ctrl-C not stop a program regardless of mode? We may never know. Even Ctrl-C and Ctrl-D are ignored in these modes. ![]() While you are in single quote mode or double quote mode, no escape sequences are respected. In this case, you'll need to enter your password in response to the prompt that mysql displays: Enter password: yourpassword. ![]() Or: mysql -userusername -password dbname. > now it will listen to your escape code: \c Invoke it from the prompt of your command interpreter as follows: mysql dbname. '> get out, in, then out again with three singlequotes: ''' databases command shows a list of all databases open in the current connection. Setting this value will help you to faster restoring of dump. If your dump size is larger set maxallowedpacket value to higher. Long story short, it was because I was not running. If you are already inside mysql prompt and assume your dump file dump.sql, then we can also use command as below to restore the dump. "> adding another doublequote breaks you out: " In other words use c:/work/ex1.db, not c:workex1.db.

Why does ctrl-c not exit mysql input mode in Windows?īecause you have told MySQL to interpret your exit commands as valid input. After this, you should be back to the > prompt and can exit with: exit I think this is safer than terminating and running your unintended query. Here's how to tell MySQL to cancel your messed-up unterminated query and put you back to the main prompt: \c Then MySQL is waiting for you to terminate a string with a quote or a query with a semi-colon. If you see this, then you can enter a command, end it with and press enter. This is powerful and the command prompt is helpful but I found it confusing until I read the answers and comments on this thread. The 'SHOW DATABASES' command actually lists the directories in the main mysql directory (which is configured in my.cnf configuration file). For example a quote or double quote may be required. You're either on the wrong instance (are there two copies of MySQL on that computer, or are you on the wrong host) or you deleted the databases. The command prompt changes to show what input is needed to terminate the query. Do you have an /etc/my.cnf file if so, cat (display) it to see where it thinks your database files should be (the datadir line). If you've entered an unterminated query, it doesn't run, and that's why typing exit doesn't work - MySQL thinks you're still in the middle of a query. Watch out for copying and pasting queries with strings from a word processing package - quotes may have been replaced with 'smart quotes' and this will mess up your query. You also need to have terminated any strings in your query. Only when you enter a semi-colon will the query be executed. SQL supports queries entered as multiple lines. ![]()
