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 { 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:

C#

String connectionString = "InitiateOAuth=GETANDREFRESH;OrganizationUrl=https://myaccount.operations.dynamics.com/;";
using (D365FinOpConnection connection = new D365FinOpConnection(connectionString)) {
  int rowsAffected;
  D365FinOpCommand cmd = new D365FinOpCommand("DELETE FROM Accounts WHERE AccountId = @myAccountId", connection);
  cmd.Parameters.Add(new D365FinOpParameter("myAccountId","'00000000-0000-0000-0000-000000000000'"));
  rowsAffected = cmd.ExecuteNonQuery();
}

VB.NET

  
Dim connectionString As [String] = "InitiateOAuth=GETANDREFRESH;OrganizationUrl=https://myaccount.operations.dynamics.com/;"
Using connection As New D365FinOpConnection(connectionString)
  Dim rowsAffected As Integer
  Dim cmd As New D365FinOpCommand("DELETE FROM Accounts WHERE AccountId = @myAccountId", connection)
  cmd.Parameters.Add(New D365FinOpParameter("myAccountId", "'00000000-0000-0000-0000-000000000000'"))
  rowsAffected = cmd.ExecuteNonQuery()
End Using
