    SqlStatement Class
    In This Topic
    Represents a single statement in a script.
    Syntax
    'Declaration
     
    Public Class SqlStatement 
    public class SqlStatement 
    Remarks

    Use SqlStatement to execute individual statements in a script. Each SqlStatement object contains SQL text and information about location of statement in the whole script.

    SqlStatement object can be obtained through DbScript.Statements collection. After originating ScriptText has been modified any obsolete SqlStatement objects can no longer be used.

    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
