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 { 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 = "URL=http://myserver:7048;User=myserver\Administrator;Password=admin;ServerInstance=DYNAMICSNAV71;";
using (DynamicsNAVConnection connection = new DynamicsNAVConnection(connectionString)) {
  int rowsAffected;
  DynamicsNAVCommand cmd = new DynamicsNAVCommand("DELETE FROM Customer WHERE Id = @myId", connection);
  cmd.Parameters.Add(new DynamicsNAVParameter("myId","http://myserver:7048/DynamicsNAV71/OData/Customer('01234567')"));
  rowsAffected = cmd.ExecuteNonQuery();
}

VB.NET

  
Dim connectionString As [String] = "URL=http://myserver:7048;User=myserver\Administrator;Password=admin;ServerInstance=DYNAMICSNAV71;"
Using connection As New DynamicsNAVConnection(connectionString)
  Dim rowsAffected As Integer
  Dim cmd As New DynamicsNAVCommand("DELETE FROM Customer WHERE Id = @myId", connection)
  cmd.Parameters.Add(New DynamicsNAVParameter("myId", "http://myserver:7048/DynamicsNAV71/OData/Customer('01234567')"))
  rowsAffected = cmd.ExecuteNonQuery()
End Using
