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 = "InitiateOAuth=GETANDREFRESH;Region='United States';Division=5512;";
using (ExactOnlineConnection connection = new ExactOnlineConnection(connectionString)) {
  int rowsAffected;
  ExactOnlineCommand cmd = new ExactOnlineCommand("DELETE FROM Accounts WHERE Id = @myId", connection);
  cmd.Parameters.Add(new ExactOnlineParameter("myId","a1f7b7c1-1ea9-4305-82b8-ab482db90a5f"));
  rowsAffected = cmd.ExecuteNonQuery();
}

VB.NET

  
Dim connectionString As [String] = "InitiateOAuth=GETANDREFRESH;Region='United States';Division=5512;"
Using connection As New ExactOnlineConnection(connectionString)
  Dim rowsAffected As Integer
  Dim cmd As New ExactOnlineCommand("DELETE FROM Accounts WHERE Id = @myId", connection)
  cmd.Parameters.Add(New ExactOnlineParameter("myId", "a1f7b7c1-1ea9-4305-82b8-ab482db90a5f"))
  rowsAffected = cmd.ExecuteNonQuery()
End Using
