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 DEPT;"+
  "CREATE TABLE DEPT ("+
  "  DEPTNO NUMBER(38) NOT NULL,"+
  "  DNAME VARCHAR2(14),"+
  "  LOC VARCHAR2(13)"+
  ");"+
  "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";
OracleConnection myConn = new OracleConnection(
    "User Id=Scott;Password=tiger;Data Source=Ora;");
OracleScript myScript = new OracleScript(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 DEPT;" + _
  "CREATE TABLE DEPT (" + _
  "  DEPTNO NUMBER(38) NOT NULL," + _
  "  DNAME VARCHAR2(14)," + _
  "  LOC VARCHAR2(13)" + _

    "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 OracleConnection = New OracleConnection( _
    "User Id=Scott;Password=tiger;Data Source=Ora;")
Dim myScript As OracleScript = New OracleScript(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()
