    SqlStatementCollection Class
    In This Topic
    Represents collection of statements that constitute DB2 script.
    Syntax
    Remarks

    The collection is read-only. You can not add your own SqlStatement objects or remove them.

    SqlStatementCollection is used to execute statements in a script one by one. To populate the collection with data use DbScript.Statements property.

    Example
    This sample shows how to retrieve collection of statements that make up the script and execute them one by one.
    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);
    SqlStatementCollection db2Coll = db2Script.Statements;
    IDataReader db2Reader;
    db2Conn.Open();
    foreach (SqlStatement db2Statement in db2Coll)
    {
      Console.WriteLine(db2Statement.Text);
      try
      {
        db2Reader = db2Statement.Execute();
        Console.WriteLine("  Records affected " + db2Reader.RecordsAffected); 
        while (db2Reader.Read()) 
        { 
          Console.WriteLine(db2Reader.GetString(0)); 
        } 
        db2Reader.Close(); 
        Console.WriteLine();
      }
      catch
      {
        Console.WriteLine("  Failed");
      }
    }
    db2Conn.Close();
    Dim script As String = _
    
        "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"
    Dim db2Conn As DB2Connection = New DB2Connection( _
        "user id=db2admin;server=db2;database=SAMPLE;")
    Dim db2Script As DB2Script = New DB2Script(script, db2Conn)
    Dim db2Coll As SqlStatementCollection = db2Script.Statements
    Dim db2Reader As IDataReader
    db2Conn.Open()
    For Each db2Statement As SqlStatement In db2Coll
      Console.WriteLine(db2Statement.Text)
      Try
        db2Reader = db2Statement.Execute()
        Console.WriteLine("  Records affected " & db2Reader.RecordsAffected)
        While db2Reader.Read()
          Console.WriteLine(db2Reader.GetString(0))
        End While
        db2Reader.Close()
        Console.WriteLine()
      Catch ex As Exception
        Console.WriteLine("  Failed")
      End Try
    Next db2Statement
    db2Conn.Close()
