SELECT INTO Statements

You can use the SELECT INTO statement to export formatted data to a file.

Data Export with an SQL Query

The following query exports data into a file formatted in comma-separated values (CSV):

SELECT City, CompanyName INTO [csv://[CData].[Default].Customers.txt] FROM [[CData].[Default].Customers] WHERE Country = 'US'
You can specify other formats in the file URI. The possible delimiters are tab, semicolon, and comma with the default being a comma. The following example exports tab-separated values:
SELECT City, CompanyName INTO [csv://[CData].[Default].Customers.txt;delimiter=tab] FROM [[CData].[Default].Customers] WHERE Country = 'US'

C#

String connectionString = "Server=127.0.0.1;Port=10000;TransportMode=BINARY";

using (ApacheHiveConnection connection = new ApacheHiveConnection(connectionString)) {
  ApacheHiveCommand cmd = new ApacheHiveCommand("SELECT City, CompanyName INTO [csv://[CData].[Default].Customers.txt] FROM [[CData].[Default].Customers] WHERE Country = 'US' ", connection);
  int rowsAffected = cmd.ExecuteNonQuery();
} 

VB.NET

Dim connectionString As [String] = "Server=127.0.0.1;Port=10000;TransportMode=BINARY" 

Using connection As New ApacheHiveConnection(connectionString)
  Dim cmd As New ApacheHiveCommand("SELECT City, CompanyName INTO [csv://[CData].[Default].Customers.txt] FROM [[CData].[Default].Customers] WHERE Country = 'US'", connection)
  Dim rowsAffected As Integer = cmd.ExecuteNonQuery()
End Using
You can specify other file formats in the URI. The following example exports tab-separated values:

C#

String connectionString = "Server=127.0.0.1;Port=10000;TransportMode=BINARY";

using (ApacheHiveConnection connection = new ApacheHiveConnection(connectionString)) {
  ApacheHiveCommand cmd = new ApacheHiveCommand("SELECT * INTO [[CData].[Default].Customers] IN [csv://filename=c:/[CData].[Default].Customers.csv;delimiter=tab] FROM [[CData].[Default].Customers] WHERE Country = 'US'", connection);
  int rowsAffected = cmd.ExecuteNonQuery();
} 

VB.NET

Dim connectionString As [String] = "Server=127.0.0.1;Port=10000;TransportMode=BINARY" 

Using connection As New ApacheHiveConnection(connectionString)
  Dim cmd As New ApacheHiveCommand("SELECT * INTO [[CData].[Default].Customers] IN [csv://filename=c:/[CData].[Default].Customers.csv;delimiter=tab] FROM [[CData].[Default].Customers] WHERE Country = 'US'", connection)
  Dim rowsAffected As Integer = cmd.ExecuteNonQuery()
End Using
