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 { ObjectID = <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 = "User=user;Password=password;";
using (SAPHybrisC4CConnection connection = new SAPHybrisC4CConnection(connectionString)) {
  int rowsAffected;
  SAPHybrisC4CCommand cmd = new SAPHybrisC4CCommand("UPDATE AccountCollection SET AccountName='John' WHERE ObjectID = @myObjectID", connection);
  cmd.Parameters.Add(new SAPHybrisC4CParameter("myObjectID","'00000000-0000-0000-0000-000000000000'"));
  rowsAffected = cmd.ExecuteNonQuery();
}

VB.NET

Dim connectionString As [String] = "User=user;Password=password;"
Using connection As New SAPHybrisC4CConnection(connectionString)
  Dim rowsAffected As Integer
  Dim cmd As New SAPHybrisC4CCommand("UPDATE AccountCollection SET AccountName='John' WHERE ObjectID = @myObjectID", connection)
  cmd.Parameters.Add(New SAPHybrisC4CParameter("myObjectID", "'00000000-0000-0000-0000-000000000000'"))
  rowsAffected = cmd.ExecuteNonQuery()
End Using
