Represents the result of a query.
Members
Array
<{name, type}> columns
Gets the columns returned in this ResultSet.
Object
info
Information on the execution of a successful query:
function
nextPage
Method used to manually fetch the next page of results.
This method is only exposed when using the eachRow
method and there are more rows available in
following pages.
String
pageState
A string token representing the current page state of query. It can be used in the following executions to continue paging and retrieve the remained of the result for the query.
Number
rowLength
Gets the row length of the result, regardless if the result has been buffered or not
Gets an array rows returned by the query, in case the result was buffered.
Constructor
Methods
@@iterator
()Gets the iterator function.
Retrieves the iterator of the underlying fetched rows and will not cause the driver to fetch the following
result pages. For more information on result paging,
visit the documentation
.
first
()Returns the first row or null if the result rows are empty.
wasApplied
()When this instance is the result of a conditional update query, it returns whether it was successful.
Otherwise, it returns true
.
For consistency, this method always returns true
for non-conditional queries (although there is
no reason to call the method in that case). This is also the case for conditional DDL statements
(CREATE KEYSPACE… IF NOT EXISTS, CREATE TABLE… IF NOT EXISTS), for which the server doesn’t return
information whether it was applied or not.
