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;";
using (KlaviyoConnection connection = new KlaviyoConnection(connectionString)) {
  int rowsAffected;
  KlaviyoCommand cmd = new KlaviyoCommand("DELETE FROM SampleTable_1 WHERE Id = @myId", connection);
  cmd.Parameters.Add(new KlaviyoParameter("myId","6"));
  rowsAffected = cmd.ExecuteNonQuery();
}

VB.NET

  
Dim connectionString As [String] = "InitiateOAuth=GETANDREFRESH;"
Using connection As New KlaviyoConnection(connectionString)
  Dim rowsAffected As Integer
  Dim cmd As New KlaviyoCommand("DELETE FROM SampleTable_1 WHERE Id = @myId", connection)
  cmd.Parameters.Add(New KlaviyoParameter("myId", "6"))
  rowsAffected = cmd.ExecuteNonQuery()
End Using
