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 { AccountId = <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;OrganizationUrl=;";
using (CDSConnection connection = new CDSConnection(connectionString)) {
  int rowsAffected;
  CDSCommand cmd = new CDSCommand("DELETE FROM Accounts WHERE AccountId = @myAccountId", connection);
  cmd.Parameters.Add(new CDSParameter("myAccountId","'00000000-0000-0000-0000-000000000000'"));
  rowsAffected = cmd.ExecuteNonQuery();


Dim connectionString As [String] = "InitiateOAuth=GETANDREFRESH;OrganizationUrl=;"
Using connection As New CDSConnection(connectionString)
  Dim rowsAffected As Integer
  Dim cmd As New CDSCommand("DELETE FROM Accounts WHERE AccountId = @myAccountId", connection)
  cmd.Parameters.Add(New CDSParameter("myAccountId", "'00000000-0000-0000-0000-000000000000'"))
  rowsAffected = cmd.ExecuteNonQuery()
End Using
