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 = "HostURL=https://my.host.oraclecloud.com; Username=abc123; Password=abcdef;";
using (OracleSalesCloudConnection connection = new OracleSalesCloudConnection(connectionString)) {
  int rowsAffected;
  OracleSalesCloudCommand cmd = new OracleSalesCloudCommand("DELETE FROM Opportunities WHERE Id = @myId", connection);
  cmd.Parameters.Add(new OracleSalesCloudParameter("myId","300000002693011"));
  rowsAffected = cmd.ExecuteNonQuery();
}

VB.NET

  
Dim connectionString As [String] = "HostURL=https://my.host.oraclecloud.com; Username=abc123; Password=abcdef;"
Using connection As New OracleSalesCloudConnection(connectionString)
  Dim rowsAffected As Integer
  Dim cmd As New OracleSalesCloudCommand("DELETE FROM Opportunities WHERE Id = @myId", connection)
  cmd.Parameters.Add(New OracleSalesCloudParameter("myId", "300000002693011"))
  rowsAffected = cmd.ExecuteNonQuery()
End Using
