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 { GoalHeadingId = <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/;Edition=Sales;";
using (Dynamics365Connection connection = new Dynamics365Connection(connectionString)) {
  int rowsAffected;
  Dynamics365Command cmd = new Dynamics365Command("DELETE FROM GoalHeadings WHERE GoalHeadingId = @myGoalHeadingId", connection);
  cmd.Parameters.Add(new Dynamics365Parameter("myGoalHeadingId","'test'"));
  rowsAffected = cmd.ExecuteNonQuery();
}

VB.NET

  
Dim connectionString As [String] = "InitiateOAuth=GETANDREFRESH;OrganizationUrl=https://myaccount.operations.dynamics.com/;Edition=Sales;"
Using connection As New Dynamics365Connection(connectionString)
  Dim rowsAffected As Integer
  Dim cmd As New Dynamics365Command("DELETE FROM GoalHeadings WHERE GoalHeadingId = @myGoalHeadingId", connection)
  cmd.Parameters.Add(New Dynamics365Parameter("myGoalHeadingId", "'test'"))
  rowsAffected = cmd.ExecuteNonQuery()
End Using
