Result Sets

You can use ResultSetMetaData to retrieve metadata about the results of a query.

The query can contain any of the following:

  • Joins
  • Aggregates
  • Aliases
  • Fully qualified names
  • Generated columns

You can instantiate a ResultSetMetaData object by invoking the getMetaData method of the Statement class. A ResultSetMetaData instance is populated with data after the statement has been executed. The following query prints out the columns in the result of the query:

String connectionString = "jdbc:amazonathena:AWSAccessKey='a123';AWSSecretKey='s123';AWSRegion='IRELAND';Database='sampledb';S3StagingDirectory='s3://bucket/staging/';";

Connection conn = DriverManager.getConnection(connectionString);
PreparedStatement pstmt = conn.prepareStatement("SELECT Name, TotalDue AS My_TotalDue, GETDATE() FROM Customers WHERE CustomerId = '12345'");
ResultSetMetaData rs = pstmt.getMetaData();
for(int i=1;i<=rs.getColumnCount();i++) {
