=item &update_full_student_data($sname,$sdom,$courseid) |
| |
|
| |
Does a lonnet::dump on a student to populate the courses tables. |
| |
|
| |
Input: $sname, $sdom, $courseid |
| |
|
| |
Output: $returnstatus |
| |
|
| |
$returnstatus is a string describing any errors that occured. 'okay' is the |
| |
default. |
| |
|
| |
This subroutine loads a students data using lonnet::dump and inserts |
| |
it into the MySQL database. The inserts are done on three tables, |
| |
$fulldump_response_table, $fulldump_part_table, and $fulldump_timestamp_table. |
| |
The INSERT calls are made directly by this subroutine, not through lonmysql |
| |
because we do a 'bulk'insert which takes advantage of MySQLs non-SQL |
| |
compliant INSERT command to insert multiple rows at a time. |
| |
If anything has gone wrong during this process, $returnstatus is updated with |
| |
a description of the error. |
| |
|
| |
Once the "fulldump" tables are updated, the tables used for chart and |
| |
spreadsheet (which hold only the current state of the student on their |
| |
homework, not historical data) are updated. If all updates have occured |
| |
successfully, $student_table is updated to reflect the time of the update. |
| |
|
| |
Notice we do not insert the data and immediately query it. This means it |
| |
is possible for there to be data returned this first time that is not |
| |
available the second time. CYA. |
