DELETE Statements

To delete information from a table, use DELETE statements.

DELETE Syntax

The DELETE statement requires the table name in the FROM clause and the row's primary key in the WHERE clause, as shown in the following example:

<delete_statement> ::= DELETE FROM <table_name> WHERE { Id = <expression> } [ { AND | OR } ... ]

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

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

C#

String connectionString = "AuthScheme=Basic;User=myUser;Password=myPassword;Security Token=myToken;";
using (SalesforceConnection connection = new SalesforceConnection(connectionString)) {
  int rowsAffected;
  SalesforceCommand cmd = new SalesforceCommand("DELETE FROM Account WHERE Id = @myId", connection);
  cmd.Parameters.Add(new SalesforceParameter("myId","1045625d-99ee-e011-a272-00155d01ad6b"));
  rowsAffected = cmd.ExecuteNonQuery();
}

VB.NET

  
Dim connectionString As [String] = "AuthScheme=Basic;User=myUser;Password=myPassword;Security Token=myToken;"
Using connection As New SalesforceConnection(connectionString)
  Dim rowsAffected As Integer
  Dim cmd As New SalesforceCommand("DELETE FROM Account WHERE Id = @myId", connection)
  cmd.Parameters.Add(New SalesforceParameter("myId", "1045625d-99ee-e011-a272-00155d01ad6b"))
  rowsAffected = cmd.ExecuteNonQuery()
End Using
