SqliteWrapper

A very simple Sqlite wrapper to plug spiders with it

• SqliteWrapper
  • How to use:
• What this library automates ?
  • Auto fill parameters
  • Migration

How to use:

// Create a new instance
SqliteDB db = new SqliteDB("myStuff.db");

// Create a DB Schema
db.CreateTables()
  .Add<MyData>()
  .Commit();

var d = new MyData()
{
    //fill your object
};
// call INSERT
db.Insert(d);

// use GetAll to retrieve all data
var allData = db.GetAll<MyData>();
// Use queries to get back data
var allBobs = db.ExecuteQuery<MyData>("SELECT * FROM MyData WHERE MyName = @name ", new { name = "bob" });

What this library automates ?

Auto fill parameters

This library provides a Query operation similar to Dapper, it can return a query as an Enumerable of your class

var allData = db.GetAll<MyData>();

And supports objects (even anonymous) as parameters

var allBobs = db.ExecuteQuery<MyData>("SELECT * FROM MyData WHERE MyName = @name ", new { name = "bob" });

Also, it supports easy Insertion

var d = new MyData()
{
    //fill your object
};
// call INSERT
db.Insert(d);

And a VERY efficient, transaction based BulkInsertion

MyData[] lotsOfData = getLotsOfData();

// call INSERT
db.BulkInsert(lotsOfData);

Tip: For multi-million insertion, 5k blocks are a good start point

Migration

This library has a very simple Migration tah can:

• Create new tables
• Add columns to existing tables

To update your db schema just call CreateTables() and add your classes with Add<T> and then Commit()

// Create a new instance
SqliteDB db = new SqliteDB("myStuff.db");

// Create a DB Schema
 var migrationResult = db.CreateTables()
                         .Add<MyData>()
                         .Commit();

A TableCommitResult will be returned with all changes made

This command will not migrate DATA only the schema

You can make changes on the table definition before it commits with:

db.CreateTables()
  .Add<MyData>()
  .ConfigureTable(t => { /* change last added table here */ })
  .Add<NextTable>()
  .Commit();
