Use ExecuteNext method to execute the statements from the script one by one. Text of the script should be specified by ScriptText property.
After the method has executed the Progress event fires where you can obtain statement text and process query results. If the statement has produced an error, event Error fires.
To restart execution from the beginning of the script call Reset method. When ScriptText property is modified DbScript automatically positions on the first statement.
string script = "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"; DB2Connection db2Conn = new DB2Connection( "user id=db2admin;server=db2;database=SAMPLE;"); DB2Script db2Script = new DB2Script(script,db2Conn); IDataReader db2Reader; db2Conn.Open(); while (db2Script.ExecuteNext(out db2Reader)) { Console.WriteLine("Records affected " + db2Reader.RecordsAffected); while (db2Reader.Read()) { Console.WriteLine(db2Reader.GetString(0)); } db2Reader.Close(); } db2Conn.Close();
