Statements Property (DbScript)

In This Topic

Gets the collection of statements that make up the script.

Syntax

Visual Basic
C#

'Declaration
 
Public ReadOnly Property Statements As SqlStatementCollection

public SqlStatementCollection Statements {get;}

Property Value

Collection of statements.

Remarks

Use Statements to obtain SqlStatementCollection which allows to access individual statements of the script and execute them manually. The collection is read-only so you can not modify it in any way. It is also bound to originating DbScript object, which means that if you have altered ScriptText, previously obtained collection will be cleared.

Example

This sample shows how to retrieve collection of statements that make up the script and execute them one by one.

csharp

string script =
  "DROP TABLE IF EXISTS DEPT;"+
  "CREATE TABLE DEPT ("+
  "  DEPTNO INT PRIMARY KEY,"+
  "  DNAME VARCHAR(14),"+
  "  LOC VARCHAR(13)"+
") TYPE = InnoDB;"+
  "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";
MySqlConnection myConn = new MySqlConnection(
    "User Id=root;Host=localhost;Database=Test;");
MySqlScript myScript = new MySqlScript(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 = _
  "DROP TABLE IF EXISTS DEPT;" + _
  "CREATE TABLE DEPT (" + _
  "  DEPTNO INT PRIMARY KEY," + _

    "INSERT INTO DEPT VALUES (30,'SALES','CHICAGO');" + _
    "INSERT INTO DEPT VALUES (40,'OPERATIONS','BOSTON');" + _
    "SELECT * FROM DEPT"
Dim myConn As MySqlConnection = New MySqlConnection( _
    "User Id=root;Host=localhost;Database=Test;")
Dim myScript As MySqlScript = New MySqlScript(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()
