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;URL=http://mySugarCRM.com;User=myUser;Password=myPassword;";
using (SugarCRMConnection connection = new SugarCRMConnection(connectionString)) {
  int rowsAffected;
  SugarCRMCommand cmd = new SugarCRMCommand("DELETE FROM Accounts WHERE Id = @myId", connection);
  cmd.Parameters.Add(new SugarCRMParameter("myId","1"));
  rowsAffected = cmd.ExecuteNonQuery();
}

VB.NET

  
Dim connectionString As [String] = "InitiateOAuth=GETANDREFRESH;URL=http://mySugarCRM.com;User=myUser;Password=myPassword;"
Using connection As New SugarCRMConnection(connectionString)
  Dim rowsAffected As Integer
  Dim cmd As New SugarCRMCommand("DELETE FROM Accounts WHERE Id = @myId", connection)
  cmd.Parameters.Add(New SugarCRMParameter("myId", "1"))
  rowsAffected = cmd.ExecuteNonQuery()
End Using
