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 = "DataModel=Relational;URI=C:\people.json";
using (JSONConnection connection = new JSONConnection(connectionString)) {
  int rowsAffected;
  JSONCommand cmd = new JSONCommand("INSERT INTO NorthwindOData (personal.name.last) VALUES ('Ana Trujilo')", connection);
  rowsAffected = cmd.ExecuteNonQuery();
}

VB.NET

Dim connectionString As [String] = "DataModel=Relational;URI=C:\people.json"
Using connection As New JSONConnection(connectionString)
  Dim rowsAffected As Integer
  Dim cmd As New JSONCommand("INSERT INTO NorthwindOData (personal.name.last) VALUES ('Ana Trujilo')", 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
