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=https://my999999.sapbydesign.com;User=username;Password=password;CustomService=servicename;";
using (SAPByDesignConnection connection = new SAPByDesignConnection(connectionString)) {
  int rowsAffected;
  SAPByDesignCommand cmd = new SAPByDesignCommand("DELETE FROM Account WHERE Id = @myId", connection);
  cmd.Parameters.Add(new SAPByDesignParameter("myId","1"));
  rowsAffected = cmd.ExecuteNonQuery();
}

VB.NET

  
Dim connectionString As [String] = "URL=https://my999999.sapbydesign.com;User=username;Password=password;CustomService=servicename;"
Using connection As New SAPByDesignConnection(connectionString)
  Dim rowsAffected As Integer
  Dim cmd As New SAPByDesignCommand("DELETE FROM Account WHERE Id = @myId", connection)
  cmd.Parameters.Add(New SAPByDesignParameter("myId", "1"))
  rowsAffected = cmd.ExecuteNonQuery()
End Using
