drh | e91cd0c | 2000-06-12 12:36:36 +0000 | [diff] [blame] | 55 | <li>Added the fcnt() function to the SQL interpreter. The fcnt() function |
| 56 | returns the number of database "Fetch" operations that have occurred. |
| 57 | This function is designed for use in test scripts to verify that |
| 58 | queries are efficient and appropriately optimized. Fcnt() has no other |
| 59 | useful purpose, as far as I know.</li> |
| 60 | <li>Added a bunch more tests that take advantage of the new fcnt() function. |

| 111 | and '_' wildcards of SQL.</li> |
| 112 | <li>Added the <B>COPY</b> command patterned after |
