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 = "SubscriptionKey=test;CountryVersion=2021.R2.AU;CompanyFile=Q:/CData Software.QBW;User=test;Password=test;InitiateOAuth=GETANDREFRESH;CallbackURL=http://localhost:33333;OAuthClientId=MyOAuthClientID;OAuthClientSecret=MyOAuthClientSecret;";
using (ReckonAccountsHostedConnection connection = new ReckonAccountsHostedConnection(connectionString)) {
  int rowsAffected;
  ReckonAccountsHostedCommand cmd = new ReckonAccountsHostedCommand("DELETE FROM Customers WHERE Id = @myId", connection);
  cmd.Parameters.Add(new ReckonAccountsHostedParameter("myId","10456255-0015501366"));
  rowsAffected = cmd.ExecuteNonQuery();
}

VB.NET

  
Dim connectionString As [String] = "SubscriptionKey=test;CountryVersion=2021.R2.AU;CompanyFile=Q:/CData Software.QBW;User=test;Password=test;InitiateOAuth=GETANDREFRESH;CallbackURL=http://localhost:33333;OAuthClientId=MyOAuthClientID;OAuthClientSecret=MyOAuthClientSecret;"
Using connection As New ReckonAccountsHostedConnection(connectionString)
  Dim rowsAffected As Integer
  Dim cmd As New ReckonAccountsHostedCommand("DELETE FROM Customers WHERE Id = @myId", connection)
  cmd.Parameters.Add(New ReckonAccountsHostedParameter("myId", "10456255-0015501366"))
  rowsAffected = cmd.ExecuteNonQuery()
End Using
