# SharpCoreDB ADO.NET Data Provider
2+
3+
? **Status**: Fully implemented and working!
4+
5+
Complete ADO.NET Data Provider for SharpCoreDB, ready for SQL Server Management Studio (SSMS) and any ADO.NET consumer.
6+
7+
> **Language:** This is the English README. For Dutch, see [`README.nl.md`](README.nl.md).
8+
9+
## ? Implemented Features

13+
2. ? `SharpCoreDBConnectionStringBuilder.cs` – Connection string parser (Path, Password)
14+
3. ? `SharpCoreDBConnection.cs` – Database connection with Open/Close/GetSchema
15+
4. ? `SharpCoreDBCommand.cs` – ExecuteNonQuery/ExecuteReader/ExecuteScalar + async
16+
5. ? `SharpCoreDBParameter.cs` – Parameter with type inference
17+

33+
## ?? Quick Start
34+
35+
### Install
36+
37+
```bash
38+
dotnet add package SharpCoreDB.Data.Provider
39+
```
40+
41+
### Basic Usage
42+
43+
```csharp
44+
using SharpCoreDB.Data.Provider;
45+
46+
// Maak connectie
47+
var connectionString = "Path=C:\\data\\mydb.scdb;Password=secret";
48+
using var connection = new SharpCoreDBConnection(connectionString);
49+
connection.Open();
50+
51+
// Maak tabel
52+
using var createCmd = new SharpCoreDBCommand(
53+
"CREATE TABLE users (id INTEGER PRIMARY KEY, name TEXT, email TEXT)",
54+
connection);
55+
createCmd.ExecuteNonQuery();
56+
57+
// Insert data met parameters
58+
using var insertCmd = new SharpCoreDBCommand(
59+
"INSERT INTO users VALUES (@id, @name, @email)",
60+
connection);
61+
insertCmd.Parameters.Add("@id", 1);
62+
insertCmd.Parameters.Add("@name", "John Doe");
63+
insertCmd.Parameters.Add("@email", "john@example.com");
64+
insertCmd.ExecuteNonQuery();
65+
66+
// Query data
67+
using var selectCmd = new SharpCoreDBCommand("SELECT * FROM users", connection);
68+
using var reader = selectCmd.ExecuteReader();
69+
while (reader.Read())
70+
{
71+
Console.WriteLine($"User: {reader.GetString(1)} ({reader.GetString(2)})");
72+
}
73+
```
74+
75+
### Factory Pattern
76+
77+
```csharp
78+
using System.Data.Common;
79+
using SharpCoreDB.Data.Provider;
80+
81+
// Registreer provider
82+
DbProviderFactories.RegisterFactory("SharpCoreDB.Data.Provider",
83+
SharpCoreDBProviderFactory.Instance);
84+
85+
// Gebruik factory
86+
var factory = DbProviderFactories.GetFactory("SharpCoreDB.Data.Provider");
87+
using var connection = factory.CreateConnection()!;
88+
connection.ConnectionString = "Path=C:\\data\\mydb.scdb;Password=secret";
89+
connection.Open();
90+
91+
using var cmd = connection.CreateCommand();
92+
cmd.CommandText = "SELECT COUNT(*) FROM users";
93+
var count = cmd.ExecuteScalar();
94+
Console.WriteLine($"Total users: {count}");
95+
```
96+
97+
### Transactions
98+
99+
```csharp
100+
using var connection = new SharpCoreDBConnection("Path=C:\\data\\mydb.scdb;Password=secret");
101+
connection.Open();
102+
103+
using var transaction = connection.BeginTransaction();
104+
try
105+
{
106+
using var cmd = new SharpCoreDBCommand("INSERT INTO logs VALUES (@msg)", connection);
107+
cmd.Transaction = (SharpCoreDBTransaction)transaction;
108+
109+
cmd.Parameters.Add("@msg", "Log entry 1");
110+
cmd.ExecuteNonQuery();
111+
112+
cmd.Parameters.Clear();
113+
cmd.Parameters.Add("@msg", "Log entry 2");
114+
cmd.ExecuteNonQuery();
115+
116+
transaction.Commit();
117+
}
118+
catch
119+
{
120+
transaction.Rollback();
121+
throw;
122+
}
123+
```
124+
125+
### Async Operations
126+
127+
```csharp
128+
await using var connection = new SharpCoreDBConnection("Path=C:\\data\\mydb.scdb;Password=secret");
129+
await connection.OpenAsync();
130+
131+
await using var cmd = new SharpCoreDBCommand("SELECT * FROM users", connection);
132+
await using var reader = await cmd.ExecuteReaderAsync();
133+
134+
while (await reader.ReadAsync())
135+
{
136+
Console.WriteLine(reader.GetString(0));
137+
}
138+
```
139+
140+
### DataAdapter (DataSet/DataTable)
141+
142+
```csharp
143+
using var connection = new SharpCoreDBConnection("Path=C:\\data\\mydb.scdb;Password=secret");
144+
connection.Open();
145+
146+
var adapter = new SharpCoreDBDataAdapter("SELECT * FROM users", connection);
147+
var dataSet = new DataSet();
148+
adapter.Fill(dataSet);
149+
150+
foreach (DataRow row in dataSet.Tables[0].Rows)
151+
{
152+
Console.WriteLine($"{row["name"]}: {row["email"]}");
153+
}
154+
```
155+
156+
## Connection String Format
157+
158+
```
159+
Path=C:\data\mydb.scdb;Password=MySecretPassword
160+
```
161+
162+
**Parameters:**
163+
- `Path` (or `Data Source`): Required. Full path to the `.scdb` database file/directory
164+
- `Password`: Required. Master password for the database
165+
166+
## SSMS Integration
167+
168+
See [`REGISTRATION.en.md`](REGISTRATION.en.md) for the English SSMS registration guide. Dutch version: [`REGISTRATION.md`](REGISTRATION.md).
169+
170+
**Quick steps:**
171+
1. Register in `machine.config`
172+
2. Optional: add to GAC
173+
3. Restart SSMS
174+
4. Use the connection string in Additional Connection Parameters
175+
