To modify existing records, use UPDATE statements.

Update Syntax

The UPDATE statement takes as input a comma-separated list of columns and new column values as name-value pairs in the SET clause, as shown in the following example:

UPDATE <table_name> SET { <column_reference> = <expression> } [ , ... ] WHERE { Id = <expression>  } [ { AND | OR } ... ] 

<expression> ::=
  | @ <parameter> 
  | ?
  | <literal>

You can use the ExecuteNonQuery method to execute data manipulation commands and retrieve the rows affected, as shown in the following example:

C#

String connectionString = "InitiateOAuth=GETANDREFRESH;AccountId=1234567;Schema=V3;ProjectId=abcd1234";
using (BasecampConnection connection = new BasecampConnection(connectionString)) {
  int rowsAffected;
  BasecampCommand cmd = new BasecampCommand("UPDATE Projects SET Name='Test Name' WHERE Id = @myId", connection);
  cmd.Parameters.Add(new BasecampParameter("myId","S"));
  rowsAffected = cmd.ExecuteNonQuery();
}

VB.NET

Dim connectionString As [String] = "InitiateOAuth=GETANDREFRESH;AccountId=1234567;Schema=V3;ProjectId=abcd1234"
Using connection As New BasecampConnection(connectionString)
  Dim rowsAffected As Integer
  Dim cmd As New BasecampCommand("UPDATE Projects SET Name='Test Name' WHERE Id = @myId", connection)
  cmd.Parameters.Add(New BasecampParameter("myId", "S"))
  rowsAffected = cmd.ExecuteNonQuery()
End Using
