+
+ <p>
+ The <codeph>NUM_ROWS_PRODUCED_LIMIT</codeph> query option limits the
number of rows
+ produced by a query. A query is canceled when its execution produces
more rows than the
+ specified limit set by the <codeph>NUM_ROWS_PRODUCED_LIMIT</codeph>
option.
+ </p>
+
+ <p>
+ This limit only applies when the results are returned to a client, for
example, to a
+ <codeph>SELECT</codeph> query, but not to an <codeph>INSERT</codeph>
query.
+ </p>
+
+ <p>
+ The default value of <codeph>0</codeph> specifies that there is no limit
on the number of
+ rows produced.
