| |
| <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. |
| </p> |
