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 = "[email protected];Password=test_1234;Domain=test.quickbase.com;ApplicationToken='bwkxrb5da2wn57bzfh9xn24';";
using (QuickBaseConnection connection = new QuickBaseConnection(connectionString)) {
  int rowsAffected;
  QuickBaseCommand cmd = new QuickBaseCommand("DELETE FROM [CData].[QuickBase].SampleTable_1 WHERE Id = @myId", connection);
  cmd.Parameters.Add(new QuickBaseParameter("myId","6"));
  rowsAffected = cmd.ExecuteNonQuery();
}

VB.NET

  
Dim connectionString As [String] = "[email protected];Password=test_1234;Domain=test.quickbase.com;ApplicationToken='bwkxrb5da2wn57bzfh9xn24';"
Using connection As New QuickBaseConnection(connectionString)
  Dim rowsAffected As Integer
  Dim cmd As New QuickBaseCommand("DELETE FROM [CData].[QuickBase].SampleTable_1 WHERE Id = @myId", connection)
  cmd.Parameters.Add(New QuickBaseParameter("myId", "6"))
  rowsAffected = cmd.ExecuteNonQuery()
End Using
