|
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.
