DELETE Statements

To delete information from a table, use DELETE statements.


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:


String connectionString = "InitiateOAuth=GETANDREFRESH;OAuthClientId=MyClientId;OAuthClientSecret=MyClientSecret;CallbackURL=http://localhost:33333";
using (FreshBooksConnection connection = new FreshBooksConnection(connectionString)) {
  int rowsAffected;
  FreshBooksCommand cmd = new FreshBooksCommand("DELETE FROM Clients WHERE Id = @myId", connection);
  cmd.Parameters.Add(new FreshBooksParameter("myId","20050"));
  rowsAffected = cmd.ExecuteNonQuery();


Dim connectionString As [String] = "InitiateOAuth=GETANDREFRESH;OAuthClientId=MyClientId;OAuthClientSecret=MyClientSecret;CallbackURL=http://localhost:33333"
Using connection As New FreshBooksConnection(connectionString)
  Dim rowsAffected As Integer
  Dim cmd As New FreshBooksCommand("DELETE FROM Clients WHERE Id = @myId", connection)
  cmd.Parameters.Add(New FreshBooksParameter("myId", "20050"))
  rowsAffected = cmd.ExecuteNonQuery()
End Using
