INSERT Statements

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 = "AuthScheme=basic;URL=http://hostname:port/rest.rsc;User=my_user;Password=my_password;";
using (ConnectConnection connection = new ConnectConnection(connectionString)) {
  int rowsAffected;
  ConnectCommand cmd = new ConnectCommand("INSERT INTO Orders (ShipCity) VALUES ('New York')", connection);
  rowsAffected = cmd.ExecuteNonQuery();
}

VB.NET

Dim connectionString As [String] = "AuthScheme=basic;URL=http://hostname:port/rest.rsc;User=my_user;Password=my_password;"
Using connection As New ConnectConnection(connectionString)
  Dim rowsAffected As Integer
  Dim cmd As New ConnectCommand("INSERT INTO Orders (ShipCity) VALUES ('New York')", connection)
  rowsAffected = cmd.ExecuteNonQuery()
End Using

Retrieving Generated Ids

In order to retrieve the Id of the last inserted record, use the SCOPE_IDENTITY function, as shown in the following example:

C#

cmd = connection.CreateCommand();
cmd.CommandText = "SELECT SCOPE_IDENTITY()";
Object returnedValues = cmd.ExecuteScalar();
String Id = (String)returnedValues;

VB.NET

cmd = connection.CreateCommand()
cmd.CommandText = "SELECT SCOPE_IDENTITY()"
Dim returnedValues As [Object] = cmd.ExecuteScalar()
Dim Id As [String] = returnedValues
