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 Name, TotalDue INTO [csv://Customer.txt] FROM [Customer] WHERE CustomerId = '12345'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 Name, TotalDue INTO [csv://Customer.txt;delimiter=tab] FROM [Customer] WHERE CustomerId = '12345'
C#
String connectionString = "User='myusername';Password='mypassword';Server='http://couchbase40'"; using (CouchbaseConnection connection = new CouchbaseConnection(connectionString)) { CouchbaseCommand cmd = new CouchbaseCommand("SELECT Name, TotalDue INTO [csv://Customer.txt] FROM [Customer] WHERE CustomerId = '12345' ", connection); int rowsAffected = cmd.ExecuteNonQuery(); }
VB.NET
Dim connectionString As [String] = "User='myusername';Password='mypassword';Server='http://couchbase40'" Using connection As New CouchbaseConnection(connectionString) Dim cmd As New CouchbaseCommand("SELECT Name, TotalDue INTO [csv://Customer.txt] FROM [Customer] WHERE CustomerId = '12345'", 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 = "User='myusername';Password='mypassword';Server='http://couchbase40'"; using (CouchbaseConnection connection = new CouchbaseConnection(connectionString)) { CouchbaseCommand cmd = new CouchbaseCommand("SELECT * INTO [Customer] IN [csv://filename=c:/Customer.csv;delimiter=tab] FROM [Customer] WHERE CustomerId = '12345'", connection); int rowsAffected = cmd.ExecuteNonQuery(); }
VB.NET
Dim connectionString As [String] = "User='myusername';Password='mypassword';Server='http://couchbase40'" Using connection As New CouchbaseConnection(connectionString) Dim cmd As New CouchbaseCommand("SELECT * INTO [Customer] IN [csv://filename=c:/Customer.csv;delimiter=tab] FROM [Customer] WHERE CustomerId = '12345'", connection) Dim rowsAffected As Integer = cmd.ExecuteNonQuery() End Using
