# react-native-sqlite

NOTE: This hasn't been maintained for a while and was never very complete to start with. Check out https://github.com/andpor/react-native-sqlite-storage for a more usable library!

A binding for sqlite3 for React Native. Allows a database to be opened and for SQL queries to be run on it.

([almostobsolete.net](http://almostobsolete.net) and

([activeinboxhq.com](http://activeinboxhq.com/)).

## Installation

Install using npm with `npm install --save react-native-sqlite`

You then need to add the Objective C part to your XCode project. Drag

`AIBSQLite.xcodeproj` from the `node_modules/react-native-sqlite` folder into your XCode project. Click on the project in XCode, goto `Build Phases` then `Link Binary With Libraries` and add `libAIBSQLite.a` and `libsqlite3.dylib`.

NOTE: Make sure you don't have the `AIBSQLite` project open seperately in XCode otherwise it won't work.

## Usage

```javascript

var sqlite = require('react-native-sqlite');

sqlite.open("filename.sqlite", function (error, database) {

  if (error) {

    console.log("Failed to open database:", error);

    return;

  }

  var sql = "SELECT a, b FROM table WHERE field=? AND otherfield=?";

  var params = ["somestring", 99];

  database.executeSQL(sql, params, rowCallback, completeCallback);

  function rowCallback(rowData) {

    console.log("Got row data:", rowData);

  }

  function completeCallback(error) {

    if (error) {

      console.log("Failed to execute query:", error);

      return

    }

    console.log("Query complete!");

    database.close(function (error) {

      if (error) {

        console.log("Failed to close database:", error);

        return

      }

    });

  }

});

```

## Database Location

It will first look for the database filename you give in the `Documents` directory inside the app sandbox. If it doesn't find anything there it will look in the app bundle and try and copy it to the `Documents` directory. If it doesn't find the database in either place then it will create a new blank database in the `Documents` directory.

In the future it should probably be made possible to open/create databases in the `tmp` and `Libraries` directories.

## Known Issues

- Doesn't support reading of BLOB fields right now. I'm not entirely sure what would be the best way to pass back binary data. Maybe Base64?

- Database needs to be closed manually. I'm not sure how I could do

  this automatically.

## Feedback Welcome!

Feedback, questions, suggestions and most of all Pull Requests are

very welcome. This is an early version and I want to figure out the

best way to continue it.

I'm also available for freelance work!
