To create new records, use INSERT statements.

INSERT Syntax

The INSERT statement specifies the columns to be inserted and the new column values. You can specify the column values in a comma-separated list in the VALUES clause, as shown in the following example:

INSERT INTO <table_name> 
( <column_reference> [ , ... ] )
VALUES 
( { <expression> | NULL } [ , ... ] ) 
  

<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 = "Server=127.0.0.1;User=admin;Password=1234;Port=9925;";
using (HarperDBConnection connection = new HarperDBConnection(connectionString)) {
  int rowsAffected;
  HarperDBCommand cmd = new HarperDBCommand("INSERT INTO [HarperDB].[cstest].Cutomers (CompanyName) VALUES ('RSSBus Inc.')", connection);
  rowsAffected = cmd.ExecuteNonQuery();
}

VB.NET

Dim connectionString As [String] = "Server=127.0.0.1;User=admin;Password=1234;Port=9925;"
Using connection As New HarperDBConnection(connectionString)
  Dim rowsAffected As Integer
  Dim cmd As New HarperDBCommand("INSERT INTO [HarperDB].[cstest].Cutomers (CompanyName) VALUES ('RSSBus Inc.')", connection)
  rowsAffected = cmd.ExecuteNonQuery()
End Using
