Example
This sample demonstrates how to execute script and retrieve information about execution flow using Progress and Error events.
[STAThread] static void Main(string[] args) { string script = "DROP TABLE DEPT;"+ "CREATE TABLE DEPT ("+ " DEPTNO INT PRIMARY KEY,"+ " DNAME VARCHAR(14),"+ " LOC VARCHAR(13)"+ ")WITH OIDS;"+ "INSERT INTO DEPT VALUES (10,'ACCOUNTING','NEW YORK');"+ "INSERT INTO DEPT VALUES (20,'RESEARCH','DALLAS');"+ "INSERT INTO DEPT VALUES (30,'SALES','CHICAGO');"+ "INSERT INTO DEPT VALUES (40,'OPERATIONS','BOSTON');"+ "SELECT * FROM DEPT"; PgSqlConnection pgConn = new PgSqlConnection( "host=server;database=test;user id=postgres;"); PgSqlScript pgScript = new PgSqlScript(script,pgConn); pgScript.Progress += new Devart.Common.ScriptProgressEventHandler(OnProgress); pgScript.Error += new Devart.Common.ScriptErrorEventHandler(OnError); pgConn.Open(); pgScript.Execute(); pgConn.Close(); } static void OnProgress(object sender, Devart.Common.ScriptProgressEventArgs e) { Console.WriteLine(e.Text); Console.WriteLine(" Successfully executed."); } static void OnError(object sender, Devart.Common.ScriptErrorEventArgs e) { e.Ignore = true; Console.WriteLine(e.Text); Console.WriteLine(" Failed."); }
