To modify existing records, use UPDATE statements.

Update Syntax

The UPDATE statement takes as input a comma-separated list of columns and new column values as name-value pairs in the SET clause, as shown in the following example:

UPDATE <table_name> SET <select_statement> | {<column_reference> = <expression> [ , ... ]} WHERE { Sid = <expression>  } [ { AND | OR } ... ] 

<expression> ::=
  | @ <parameter> 
  | ?
  | <literal>

You can use the ExecuteNonQuery method to execute data manipulation commands and retrieve the rows affected, as shown in the following example:

C#

String connectionString = "AccountSid=MyAccountSid;AuthToken=MyAuthToken;";
using (TwilioConnection connection = new TwilioConnection(connectionString)) {
  int rowsAffected;
  TwilioCommand cmd = new TwilioCommand("UPDATE Applications SET Name='MyApp2' WHERE Sid = @mySid", connection);
  cmd.Parameters.Add(new TwilioParameter("mySid","AP5ddf534702934bd3a446d293e8cdeb1f"));
  rowsAffected = cmd.ExecuteNonQuery();
}

VB.NET

Dim connectionString As [String] = "AccountSid=MyAccountSid;AuthToken=MyAuthToken;"
Using connection As New TwilioConnection(connectionString)
  Dim rowsAffected As Integer
  Dim cmd As New TwilioCommand("UPDATE Applications SET Name='MyApp2' WHERE Sid = @mySid", connection)
  cmd.Parameters.Add(New TwilioParameter("mySid", "AP5ddf534702934bd3a446d293e8cdeb1f"))
  rowsAffected = cmd.ExecuteNonQuery()
End Using
