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 = "Server=127.0.0.1;Port=21050;";
using (ApacheImpalaConnection connection = new ApacheImpalaConnection(connectionString)) {
  int rowsAffected;
  ApacheImpalaCommand cmd = new ApacheImpalaCommand("INSERT INTO [CData].[Default].Customers (CompanyName) VALUES ('RSSBus Inc.')", connection);
  rowsAffected = cmd.ExecuteNonQuery();
}

VB.NET

Dim connectionString As [String] = "Server=127.0.0.1;Port=21050;"
Using connection As New ApacheImpalaConnection(connectionString)
  Dim rowsAffected As Integer
  Dim cmd As New ApacheImpalaCommand("INSERT INTO [CData].[Default].Customers (CompanyName) VALUES ('RSSBus Inc.')", connection)
  rowsAffected = cmd.ExecuteNonQuery()
End Using
