The sqlite3 command line tool features the [`.backup` dot command](https://sqlite.org/cli.html#special_commands_to_sqlite3_dot_commands_).

You can connect to your database with:

    sqlite3 my_database.sq3

and run the backup dot command with:

    .backup backup_file.sq3

Instead of the interactive connection to the database, you can also do the backup and close the connection afterwards with

    sqlite3 my_database.sq3 &quot;.backup &#39;backup_file.sq3&#39;&quot;

Either way the result is a copy named `backup_file.sq3` of the database `my_database.sq3`.

It&#39;s different from regularly file copying, because it takes care of any users currently working on the database. There are proper locks set on the database, so the backup is done exclusively.


.backup is the best way. 

    sqlite3 my_database .backup my_database.back

you can also try .dump command , it gives you the ability to dump the entire database or tables into a text file. If TABLE specified, only dump tables matching LIKE pattern TABLE.

    sqlite3 my_database .dump &gt; my_database.back

A good way to make an archival copy using dump and store, Reconstruct the database at a later time.

    sqlite3 my_database .dump | gzip -c &gt; my_database.dump.gz
    zcat my_database.dump.gz | sqlite3 my_database

**Short and simple answer would be**

`sqlite3 m_database.sq3 &quot;.backup m_database.sq3.bak&quot;`

Getting the complaint from the compiler when I am doing this

    class ViewController: UIViewController {
        
        var delegate : AppDelegate
        override func viewDidLoad() {
            super.viewDidLoad()
            // Do any additional setup after loading the view, typically from a nib.
            //self.appDelegate = UIApplication.sharedApplication().delegate;
            
        }
    
        @IBAction func getData(sender : AnyObject) {
            
        }
    
        @IBAction func LogOut(sender : AnyObject) {
        }
    }

However, if I just add *?* at the end of *AppDelegate* like below and the error is gone.

    class ViewController: UIViewController {
        
        var delegate : AppDelegate?
        override func viewDidLoad() {
            super.viewDidLoad()
            // Do any additional setup after loading the view, typically from a nib.
            //self.appDelegate = UIApplication.sharedApplication().delegate;
            
        }
    
        @IBAction func getData(sender : AnyObject) {
            
        }
    
        @IBAction func LogOut(sender : AnyObject) {
        }
    }

I don&#39;t see *`optional`* keyword relevant to this error unless I am wrong.

The Hibernate Documentation has the information below for the `@Temporal` annotation:

&gt; In plain Java APIs, the temporal precision of time is not defined.
&gt; When dealing with temporal data you might want to describe the
&gt; expected precision in database. Temporal data can have DATE, TIME, or
&gt; TIMESTAMP precision (ie the actual date, only the time, or both). Use
&gt; the @Temporal annotation to fine tune that.

What does `temporal precision of time is not defined` mean? What is `temporal` data and its precision? How does it fine tune?

What is the use of the @Temporal annotation in Hibernate?

Is there any way to set some sort of &quot;expiry&quot; time on data entries in [PostgreSQL][1]? I&#39;m thinking about something equivalent to [`EXPIRE` in Redis][2].

I&#39;m not looking to store a timestamp and then manually code some sort of [cron][3] job to check what entries have expired.

I&#39;m trying to find out if there&#39;s any native feature in PostgreSQL that would provide this kind of functionality, or if it would make sense to request such feature for future releases.

Although one can use composite primary keys, for the case below, is it really a bad practice? The consensus on Stackoveflow *seems to go both ways on this issue*.

Why?

---

I want to store payments for the orders in a separate table. The reason is that, an order can have many items which are handled in a separate table in the form of many to many relationship. Now, if I don&#39;t use composite primary keys for my payment table, I&#39;ll lose my unique `PaymentID`:

    [PaymentId] INT IDENTITY(1,1) NOT NULL PRIMARY KEY,
    [OrderId] INT NOT NULL PRIMARY KEY --Also a Foreign Key--

Now, if I just remove the Primary Key for the `OrderId`, I&#39;ll lose my one to one relationship here so `Many OrderIds can be associated to many PaymentIds`, and I don&#39;t want this. 

This seems to be why other answers on SO have concluded (mostly) that the composite key is a bad idea. If it is bad, what&#39;s the best practice then?

I have a tsv (tab separated file) that I would like to import with sqlite3. Does someone know a clear way to do it?

I have installed sqlite3, but not created any database or tables yet.

I&#39;ve tried the command 

    .import /path/filename.tsv my_new_table

but it gives me the error: no such table: my_new_table.

However, from what I&#39;d read it should create the table automatically if it does&#39;t exist. Does it mean I need to create and use a database first, or is there another trick to importing a .tsv file into sqlite?

I have a site that I&#39;ve built with Flask SQLAlchemy and SQLite, and need to switch to MySQL. I have migrated the database itself and have it running under MySQL, but 

 1. Can&#39;t figure out how to connect to the MySQL database (that is, what the `SQLALCHEMY_DATABASE_URI` should be) and
 2. Am unclear if any of my existing SQLAlchemy SQLite code will work with MySQL.

I suspect that (1) is fairly simple and just a matter of being shown how to map, for example, the contents of the connection dialog I use in my MySQL database tool to an appropriately formatted URL. But I&#39;m worried about (2), I had assumed that SQLAlchemy provided an abstraction layer so that [simple SQLAlchemy code such as][1] 

    from flask import Flask
    from flask.ext.sqlalchemy import SQLAlchemy
    
    app = Flask(__name__)
    app.config[&#39;SQLALCHEMY_DATABASE_URI&#39;] = &#39;sqlite:////tmp/test.db&#39;
    db = SQLAlchemy(app)
    
    
    class User(db.Model):
        id = db.Column(db.Integer, primary_key=True)
        username = db.Column(db.String(80), unique=True)
        email = db.Column(db.String(120), unique=True)
    
        def __init__(self, username, email):
            self.username = username
            self.email = email
    
        def __repr__(self):
            return &#39;&lt;User %r&gt;&#39; % self.username
    
    admin = User(&#39;admin&#39;, &#39;admin@example.com&#39;)
    
    db.session.add(admin)
    
    User.query.all()
    
    User.query.filter_by(username=&#39;admin&#39;).first()

wold work without any modifications other than an appropriate change to the database URI; but the [examples I&#39;ve found][2] for using SQLAlchemy with MySQL seem to use a completely different API.

Can I (2) migrate my Flask SQLAlchemy code to work with a MySQL database by simply changing the database URI and if so (1) what should that URI be?

Switching from SQLite to MySQL with Flask SQLAlchemy

I&#39;m having a hard time understanding how to use full text search (FTS) with Android. I&#39;ve read the [SQLite documentation on the FTS3 and FTS4 extensions][1]. And I know [it&#39;s possible to do on Android][2]. However, I&#39;m having a hard time finding any examples that I can comprehend.

# The basic database model

A SQLite database table (named `example_table`) has 4 columns. However, there is only one column (named `text_column`) that needs to be indexed for a full text search. Every row of `text_column` contains text varying in length from 0 to 1000 words. The total number of rows is greater than 10,000. 

- How would you set up the table and/or the FTS virtual table? 
- How would you perform an FTS query on `text_column`?

**Additional notes:**

- Because only one column needs to be indexed, only using an FTS table (and dropping `example_table`) would be [inefficient for non-FTS queries][4].
- For such a large table, storing duplicate entries of `text_column` in the FTS table would be undesirable. [This post][5] suggests using an [external content table][6].
- External content tables use FTS4, but FTS4 is [not supported before Android API 11][7]. An answer can assume an API &gt;= 11, but commenting on options for supporting lower versions would be helpful.
- Changing data in the original table does not automatically update the FTS table (and vice versa). Including [triggers][8] in your answer is not necessary for this basic example, but would be helpful nonetheless.

Any ideas what could be causing crashes like this?

I&#39;ve been using this Docker-image [tutum/wordpress][1] to demonstrate a Wordpress website. Recently I found out that the image uses volumes for the MySQL-data.

So the problem is this: If I want to backup and restore the container I can try to commit an image, and then later delete the container, and create a new container from the committed image. But if I do that the volume gets deleted and all my data is gone.

There must be some simple way to backup my container plus its volume-data but I can&#39;t find it anywhere.

How can I backup a Docker-container with its data-volumes?

I have recently started using Atom editor. Its pretty great so far. I am planning to install it on several other machines.

How can I replicate the config and list of packages installed on my current machine to other machines. Is there a config that I can use to export and import them on other machines.



How to save Atom editor config and list of packages installed

So I was adding some stuff to my application manifest and I saw that I had a warning on my application tag:

&gt; On SDK version 23 and up, your app data will be automatically backed up and restored on app install. Consider adding the attribute android:fullBackupContent to specify an @xml resource which configures which files to backup.

And then I searched up for that. Apparently there are only 2 tags for that: `&lt;include&gt;` and `&lt;exclude&gt;`. I don&#39;t want to exclude any files from the backup as I don&#39;t have any local-depending files, and I don&#39;t need any `&lt;include&gt;` tags as

&gt; **`&lt;include&gt;:`** Specifies a set of resources to back up, instead of having the system back up all data in your app by default.

When I saw that if I don&#39;t put any `&lt;include&gt;` tags, then the system will `back up all data in your app by default`, which is exactly what I want.

Now I have this question: should I add the `backup_content.xml` file, but empty as the default settings are good, or not add the file at all? (in which case Android Studio will complain)

Should full backup content xml file be empty or not added at all to include all?

I take backup using 

    pg_dump db_production &gt; postgres_db.dump

and then I copy it to localhost using scp.

Now when I import on my local db it gives an error 

    pg_restore: [archiver] input file appears to be a text format dump. Please use psql.

by using commad line

    pg_restore -d db_development postgres_db.dump


input file appears to be a text format dump. Please use psql

Does the google firestore database service provides a backup?
If so, how do I backup the database and how do I restore in case of an error?
