Result Set Data Usage (Snapshot Queries)

Use the Query.Statement.execute() function to returns values in a result set.

See Obtain Results Using a Result Set for details about obtaining results.

• Move the Cursor to the Next Row
  The result set maintains a cursor (that is, a reference) on the current row, initially positioned just before the first row so that you can perform operations on the table. The only way to do operations on the table is through the cursor.
• Count of Records in Certain Result Sets
  You can use the getRowCountIfPossible() function to get the count of records in a result set when using Query Functions.
