Using SQL Driver

by itools@albertoschiassi.it on martedì 6 agosto 2013 23:20
Per utilizzare il driver SqlStore occorre impostare: 

  1. la proprietà ConnectionString; 
  2. la proprietà TableName; 

Entrambe le proprietà indicate sopra sono da impostare attraverso le AdvacedProperties dell'IOServer. Se la tabella non esiste viene create automaticamente in fase di avvio ed è strutturata nel seguente modo:

Di seguito un esempio di utilizzo dei driver IToolS SQL:

using System.Windows.Forms;

Lo stesso driver è disponibile anche per MySql impostando la proprietà "Name" dell'IOServer a "MySqlStore".
