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 { RowId = <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 = "Excel File=C:\MyExcelWorkbooks\SampleWorkbook.xlsx;";
using (ExcelConnection connection = new ExcelConnection(connectionString)) {
  int rowsAffected;
  ExcelCommand cmd = new ExcelCommand("DELETE FROM Sheet WHERE RowId = @myRowId", connection);
  cmd.Parameters.Add(new ExcelParameter("myRowId","5"));
  rowsAffected = cmd.ExecuteNonQuery();
}

VB.NET

  
Dim connectionString As [String] = "Excel File=C:\MyExcelWorkbooks\SampleWorkbook.xlsx;"
Using connection As New ExcelConnection(connectionString)
  Dim rowsAffected As Integer
  Dim cmd As New ExcelCommand("DELETE FROM Sheet WHERE RowId = @myRowId", connection)
  cmd.Parameters.Add(New ExcelParameter("myRowId", "5"))
  rowsAffected = cmd.ExecuteNonQuery()
End Using
