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 Id, Name INTO [csv://hpcc::test::person.txt] FROM [hpcc::test::person] WHERE Industry = 'Floppy Disks'
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 Id, Name INTO [csv://hpcc::test::person.txt;delimiter=tab] FROM [hpcc::test::person] WHERE Industry = 'Floppy Disks'

C#

String connectionString = "URL=http://127.0.0.1:8510;User=test;Password=xA123456;Version=1;Cluster=hthor;";

using (HPCCConnection connection = new HPCCConnection(connectionString)) {
  HPCCCommand cmd = new HPCCCommand("SELECT Id, Name INTO [csv://hpcc::test::person.txt] FROM [hpcc::test::person] WHERE Industry = 'Floppy Disks' ", connection);
  int rowsAffected = cmd.ExecuteNonQuery();
} 

VB.NET

Dim connectionString As [String] = "URL=http://127.0.0.1:8510;User=test;Password=xA123456;Version=1;Cluster=hthor;" 

Using connection As New HPCCConnection(connectionString)
  Dim cmd As New HPCCCommand("SELECT Id, Name INTO [csv://hpcc::test::person.txt] FROM [hpcc::test::person] WHERE Industry = 'Floppy Disks'", 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 = "URL=http://127.0.0.1:8510;User=test;Password=xA123456;Version=1;Cluster=hthor;";

using (HPCCConnection connection = new HPCCConnection(connectionString)) {
  HPCCCommand cmd = new HPCCCommand("SELECT * INTO [hpcc::test::person] IN [csv://filename=c:/hpcc::test::person.csv;delimiter=tab] FROM [hpcc::test::person] WHERE Industry = 'Floppy Disks'", connection);
  int rowsAffected = cmd.ExecuteNonQuery();
} 

VB.NET

Dim connectionString As [String] = "URL=http://127.0.0.1:8510;User=test;Password=xA123456;Version=1;Cluster=hthor;" 

Using connection As New HPCCConnection(connectionString)
  Dim cmd As New HPCCCommand("SELECT * INTO [hpcc::test::person] IN [csv://filename=c:/hpcc::test::person.csv;delimiter=tab] FROM [hpcc::test::person] WHERE Industry = 'Floppy Disks'", connection)
  Dim rowsAffected As Integer = cmd.ExecuteNonQuery()
End Using
