DELETE Statements

To delete information from a table, use DELETE statements.


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:


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();


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
