SqlStatementCollection Class

In This Topic

Represents collection of statements that constitute SQL Server script.

Syntax

Visual Basic
C#

'Declaration
 
Public Class SqlStatementCollection 
   Inherits System.Collections.CollectionBase
   Implements System.Collections.ICollection, System.Collections.IEnumerable, System.Collections.IList

public class SqlStatementCollection : System.Collections.CollectionBase, System.Collections.ICollection, System.Collections.IEnumerable, System.Collections.IList

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.

csharp

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";
SqlConnection myConn = new SqlConnection(
    "User Id=sa;Server=localhost;Initial Catalog=Test;");
SqlScript myScript = new SqlScript(script,myConn);
SqlStatementCollection myColl = myScript.Statements;
IDataReader myReader;
myConn.Open();
foreach (SqlStatement myStatement in myColl)
{
  Console.WriteLine(myStatement.Text);
  try
  {
    myReader = myStatement.Execute();
    Console.WriteLine("  Records affected " + myReader.RecordsAffected); 
    while (myReader.Read()) 
    { 
      Console.WriteLine(myReader.GetString(0)); 
    } 
    myReader.Close(); 
    Console.WriteLine();
  }
  catch
  {
    Console.WriteLine("  Failed");
  }
}
myConn.Close();

Visual Basic

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 myConn As SqlConnection = New SqlConnection( _
    "User Id=sa;Server=localhost;Initial Catalog=Test;")
Dim myScript As SqlScript = New SqlScript(script, myConn)
Dim myColl As SqlStatementCollection = myScript.Statements
Dim myReader As IDataReader
myConn.Open()
For Each myStatement As SqlStatement In myColl
  Console.WriteLine(myStatement.Text)
  Try
    myReader = myStatement.Execute()
    Console.WriteLine("  Records affected " & myReader.RecordsAffected)
    While myReader.Read()
      Console.WriteLine(myReader.GetString(0))
    End While
    myReader.Close()
    Console.WriteLine()
  Catch ex As Exception
    Console.WriteLine("  Failed")
  End Try
Next myStatement
myConn.Close()
