Slide 5: Example 1 - Connecting to MS SQL Server
Objective: Connect to an MS SQL Server database, execute a query, and retrieve results in JSON.
C# Example
using Multilink;
class Program
{
static void Main()
{
// Configure connection
MSSQL_CLIENT.CONFIGURE("server_name", "user", "password", "database", true, true);
if (MSSQL_CLIENT.BEGIN_CONNECT())
{
Console.WriteLine("Connected to database!");
// Execute query
MSSQL_CLIENT.SQL_QUERY("SELECT * FROM Clientes WHERE ClienteID = @ClienteID");
MSSQL_CLIENT.SET("ClienteID", 1001);
Console.WriteLine(MSSQL_CLIENT.DATA); // Results in JSON
MSSQL_CLIENT.END_CONNECT();
}
else
{
Console.WriteLine("Error: " + MSSQL_CLIENT.MSG);
}
}
}
WLanguage Example
MultilinkConfigure("server_name", "user", "password", "database", True, True)
IF MultilinkBeginConnect() THEN
Info("Connected to database!")
MultilinkSQLQuery("SELECT * FROM Clientes WHERE ClienteID = @ClienteID")
MultilinkSet("ClienteID", 1001)
Info(MultilinkDATA())
MultilinkEndConnect()
ELSE
Info(MultilinkMSG())
END
Explanation:
• Configures a secure connection to MS SQL Server.
• Executes a parameterized SELECT query to retrieve client data.
• Returns results in JSON format for easy processing.

Slide 6: Example 2 - Transaction Management with PostgreSQL
Objective: Insert a new record into a PostgreSQL database with transaction control to ensure data consistency.
C# Example
using Multilink;
class Program
{
static void Main()
{
POSTGRESQL_CLIENT.CONFIGURE("localhost", 15432, "postgres", "123456", "postgres", "public");
if (POSTGRESQL_CLIENT.BEGIN_CONNECT())
{
if (POSTGRESQL_CLIENT.BEGIN_TRANSACTION())
{
POSTGRESQL_CLIENT.SET("@nome", "John Doe");
POSTGRESQL_CLIENT.SET("@email", "john@example.com");
bool inserted = POSTGRESQL_CLIENT.SQL_EXEC("INSERT INTO Clientes (Nome, Email) VALUES (@nome, @email)");
if (inserted)
{
POSTGRESQL_CLIENT.COMMIT_TRANSACTION(true);
Console.WriteLine("Insert successful!");
}
else
{
POSTGRESQL_CLIENT.ROLLBACK_TRANSACTION();
Console.WriteLine("Error: " + POSTGRESQL_CLIENT.MSG);
}
}
POSTGRESQL_CLIENT.END_CONNECT();
}
else
{
Console.WriteLine("Error: " + POSTGRESQL_CLIENT.MSG);
}
}
}
WLanguage Example
POSTGRESQL_CLIENT.CONFIGURE("localhost", 15432, "postgres", "123456", "postgres", "public")
IF POSTGRESQL_CLIENT.BEGIN_CONNECT() THEN
IF POSTGRESQL_CLIENT.BEGIN_TRANSACTION() THEN
POSTGRESQL_CLIENT.SET("@nome", "John Doe")
POSTGRESQL_CLIENT.SET("@email", "john@example.com")
atualizado is boolean = POSTGRESQL_CLIENT.SQL_EXEC("INSERT INTO Clientes (Nome, Email) VALUES (@nome, @email)")
IF atualizado THEN
POSTGRESQL_CLIENT.COMMIT_TRANSACTION(True)
Info("Insert successful!")
ELSE
POSTGRESQL_CLIENT.ROLLBACK_TRANSACTION()
Info(POSTGRESQL_CLIENT.MSG)
END
END
POSTGRESQL_CLIENT.END_CONNECT()
ELSE
Info(POSTGRESQL_CLIENT.MSG)
END
Explanation:
• Establishes a connection to a PostgreSQL database.
• Uses a transaction to ensure the INSERT operation is atomic.
• Commits the transaction on success or rolls back on failure.

Slide 7: Example 3 - Email Notifications
Objective: Update a record and send an email notification to the client using Multilink’s email functionality.
C# Example
using Multilink;
class Program
{
static void Main()
{
MSSQL_CLIENT.CONFIGURE("server", "user", "password", "database", true, true);
if (MSSQL_CLIENT.BEGIN_CONNECT())
{
MSSQL_CLIENT.SET("Status", "Shipped");
MSSQL_CLIENT.SET("PedidoID", 1000);
MSSQL_CLIENT.SQL_EXEC("UPDATE Pedidos SET Status = @Status WHERE PedidoID = @PedidoID");
// Send email notification
EMAIL_CLIENT.CONFIGURE("smtp.server.com", 587, true, "user@server.com", "password");
EMAIL_CLIENT.TEXT_EMAIL("cliente@exemplo.com", "Order Shipped", "Your order has been shipped.");
Console.WriteLine(MSSQL_CLIENT.MSG);
MSSQL_CLIENT.END_CONNECT();
}
else
{
Console.WriteLine("Error: " + MSSQL_CLIENT.MSG);
}
}
}
WLanguage Example
MultilinkConfigure("server", "user", "password", "database", True, True)
IF MultilinkBeginConnect() THEN
MultilinkSet("Status", "Shipped")
MultilinkSet("PedidoID", 1000)
MultilinkSQLExec("UPDATE Pedidos SET Status = @Status WHERE PedidoID = @PedidoID")
MultilinkEmailConfigure("smtp.server.com", 587, True, "user@server.com", "password")
MultilinkEmailText("cliente@exemplo.com", "Order Shipped", "Your order has been shipped.")
Info(MultilinkMSG())
MultilinkEndConnect()
ELSE
Info(MultilinkMSG())
END
Explanation:
• Updates the status of an order in the database.
• Sends a text-based email notification to the client.
• Demonstrates Multilink’s ability to handle both database operations and email communication.

Slide 8: Example 4 - Oracle Database Connection
Objective: Connect to an Oracle database using SID and retrieve data.
C# Example
using Multilink;
class Program
{
static void Main()
{
ORACLE_CLIENT.ConfigureWithSID("myServer", "1521", "mySID", "myUser", "myPassword");
if (ORACLE_CLIENT.BEGIN_CONNECT())
{
Console.WriteLine("Connected to Oracle database!");
ORACLE_CLIENT.SQL_QUERY("SELECT * FROM Employees WHERE DepartmentID = :deptID");
ORACLE_CLIENT.SET_PARAM("deptID", "10");
Console.WriteLine(ORACLE_CLIENT.DATA); // Results in JSON
ORACLE_CLIENT.END_CONNECT();
}
else
{
Console.WriteLine("Error: " + ORACLE_CLIENT.MSG);
}
}
}
WLanguage Example
ConfigureWithSID("myServer", "1521", "mySID", "myUser", "myPassword")
IF ORACLE_CLIENT:BEGIN_CONNECT() THEN
Info("Connected to Oracle database!")
ORACLE_CLIENT:SQL_QUERY("SELECT * FROM Employees WHERE DepartmentID = :deptID")
ORACLE_CLIENT:SET_PARAM("deptID", "10")
Info(ORACLE_CLIENT.DATA)
ORACLE_CLIENT:END_CONNECT()
ELSE
Info(ORACLE_CLIENT.MSG)
END
Explanation:
• Configures a connection to an Oracle database using SID.
• Executes a parameterized query to retrieve employee data.
• Returns results in JSON format.

Slide 9: Example 5 - Complex Transaction with Multiple Tables
Objective: Insert a client, order, items, and taxes in a single transaction.
C# Example
using Multilink;
class Program
{
static void Main()
{
MSSQL_CLIENT.CONFIGURE("server", "user", "password", "database", true, true);
if (MSSQL_CLIENT.BEGIN_CONNECT() && MSSQL_CLIENT.BEGIN_TRANSACTION())
{
try
{
// Insert client
MSSQL_CLIENT.SET("Nome", "Cliente Exemplo");
MSSQL_CLIENT.SET("Endereco", "Rua Exemplo, 123");
if (!MSSQL_CLIENT.SQL_EXEC("INSERT INTO Clientes (Nome, Endereco) VALUES (@Nome, @Endereco)"))
throw new Exception(MSSQL_CLIENT.MSG);
MSSQL_CLIENT.SQL_QUERY("SELECT SCOPE_IDENTITY() AS ClienteID");
int clienteID = Convert.ToInt32(MSSQL_CLIENT.DATA);
// Insert order
MSSQL_CLIENT.SET("ClienteID", clienteID);
MSSQL_CLIENT.SET("DataPedido", DateTime.Now);
if (!MSSQL_CLIENT.SQL_EXEC("INSERT INTO Pedidos (ClienteID, DataPedido) VALUES (@ClienteID, @DataPedido)"))
throw new Exception(MSSQL_CLIENT.MSG);
MSSQL_CLIENT.SQL_QUERY("SELECT SCOPE_IDENTITY() AS PedidoID");
int pedidoID = Convert.ToInt32(MSSQL_CLIENT.DATA);
// Insert items
MSSQL_CLIENT.SET("PedidoID", pedidoID);
MSSQL_CLIENT.SET("ProdutoID1", 101);
MSSQL_CLIENT.SET("Quantidade1", 2);
MSSQL_CLIENT.SET("ProdutoID2", 102);
MSSQL_CLIENT.SET("Quantidade2", 5);
if (!MSSQL_CLIENT.SQL_EXEC("INSERT INTO Pedidos_Itens (PedidoID, ProdutoID, Quantidade) VALUES (@PedidoID, @ProdutoID1, @Quantidade1), (@PedidoID, @ProdutoID2, @Quantidade2)"))
throw new Exception(MSSQL_CLIENT.MSG);
// Insert taxes
MSSQL_CLIENT.SET("ImpostoID1", 1);
MSSQL_CLIENT.SET("Valor1", 50);
MSSQL_CLIENT.SET("ImpostoID2", 2);
MSSQL_CLIENT.SET("Valor2", 30);
if (!MSSQL_CLIENT.SQL_EXEC("INSERT INTO Impostos (PedidoID, ImpostoID, Valor) VALUES (@PedidoID, @ImpostoID1, @Valor1), (@PedidoID, @ImpostoID2, @Valor2)"))
throw new Exception(MSSQL_CLIENT.MSG);
