Console doesn't work with sqLite3

Console does't work

My version of the console as of now is 

treehouse:~/workspace$ sqlite3                                                        
SQLite version 3.7.17 2013-05-20 00:56:22

But the video's version is

```treehouse:~/workspace$ sqlite3 SQLite version 3.8.2 2013-12-04 14:53:30

Which seems to me to suggest that workspaces has reverted back to an earlier version which is not compatable with the suggested commands.

I can get into ```sqlite3``` by typing the command


But as soon as I try to open a database ```sqlite3 database.db``` I get locked in and no other commands will work.


```sqlite> sqlite3 database.db                                                           
   ...>

Help! :-)

I see , normally after using the sqlite3 command in the console

sqlite3

After the sqlite3 console prompt shows up

sqlite >

you can not us sqlite3 database command . Since there is no comand name sqlite3 in the sqlite3 commands.

Instead from the from the workspaces console prompt type in sqlite3 followed by the database name you want to target.

If its not already there, it will be created.

I would also delete all databases in the workspaces and make a new fresh copy/import of the database.

Thank you Shadrack. It seems to be working now.

I'm sure in Hampton;s version he was able to link the databases from inside of sqlite so i was following that setup rigidly. But I was able to get around by following your advice, so thanks for that :)

To start using sqlite3 make sure you type sqlite3 database.db in a blank workspace like:

treehouse:~/workspace$ sqlite3 database.db

That is; if you are already using in sqlit3 , to open database.db use .open command

treehouse:~/workspace$ sqlite3                                             
. . .
sqlite> .open database.db

You can also just exit using .exit command to exit and open the database afresh. 

.exit

Then go ahead and open the database

 sqlite3 database.db

You can now use "SQL" commands to create tables, manipulate data, and so on.

You can also use sqlite3 dot commands commands like:

.databases

will list all databases

.tables

will show all tables in the database

.help

to see more other sqlite3 commands.

NOTE: not all dot commands are available in the open database, since each command may have a particular context in which to function.

See Sqlite3 commanline official documentation

Thanks Shadrock, but it doesn't work.

The .open command is deprecated on my console and it locks out as soon as I try

sqlite3 database.db

I see, I cant use the .open command either . In stead I used sqlite3 database.db, if you are using the same version then you will be ok. Here is what workspaces output tooks like.

sqlite3 database.db then .databases command

treehouse:~/workspace$ sqlite3 database.db                                                         
SQLite version 3.7.17 2013-05-20 00:56:22                                                          
Enter ".help" for instructions                                                                     
Enter SQL statements terminated with a ";"                                                         
sqlite> .databases

resulting output , shows the database :

seq  name             file                                                                         
---  ---------------  ----------------------------------------------------------                   
0    main             /home/treehouse/workspace/database.db

.table command

sqlite> .tables

Outputs all the tables in the database. 

address                 film_actor              rental

That's part of the problem. We're using different versions of Workspaces to the video. Does anyone know of a way to use a different Workspaces version? :-)

This is how my console looks. As you can see it also gives the Workspaces version and the commands I've tried to use.
