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 FullPath, Permission INTO [csv://Resources.txt] FROM [Resources] WHERE Type = 'FILE'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 FullPath, Permission INTO [csv://Resources.txt;delimiter=tab] FROM [Resources] WHERE Type = 'FILE'
C#
String connectionString = "Schema=ADLSGen2;Account=MyStorageAccount;FileSystem=MyBlobContainer;AccessKey=myAccessKey;"; using (ADLSConnection connection = new ADLSConnection(connectionString)) { ADLSCommand cmd = new ADLSCommand("SELECT FullPath, Permission INTO [csv://Resources.txt] FROM [Resources] WHERE Type = 'FILE' ", connection); int rowsAffected = cmd.ExecuteNonQuery(); }
VB.NET
Dim connectionString As [String] = "Schema=ADLSGen2;Account=MyStorageAccount;FileSystem=MyBlobContainer;AccessKey=myAccessKey;" Using connection As New ADLSConnection(connectionString) Dim cmd As New ADLSCommand("SELECT FullPath, Permission INTO [csv://Resources.txt] FROM [Resources] WHERE Type = 'FILE'", connection) Dim rowsAffected As Integer = cmd.ExecuteNonQuery() End UsingYou can specify other file formats in the URI. The following example exports tab-separated values:
C#
String connectionString = "Schema=ADLSGen2;Account=MyStorageAccount;FileSystem=MyBlobContainer;AccessKey=myAccessKey;"; using (ADLSConnection connection = new ADLSConnection(connectionString)) { ADLSCommand cmd = new ADLSCommand("SELECT * INTO [Resources] IN [csv://filename=c:/Resources.csv;delimiter=tab] FROM [Resources] WHERE Type = 'FILE'", connection); int rowsAffected = cmd.ExecuteNonQuery(); }
VB.NET
Dim connectionString As [String] = "Schema=ADLSGen2;Account=MyStorageAccount;FileSystem=MyBlobContainer;AccessKey=myAccessKey;" Using connection As New ADLSConnection(connectionString) Dim cmd As New ADLSCommand("SELECT * INTO [Resources] IN [csv://filename=c:/Resources.csv;delimiter=tab] FROM [Resources] WHERE Type = 'FILE'", connection) Dim rowsAffected As Integer = cmd.ExecuteNonQuery() End Using
