Access report details

Dear Experts,

There is MS ACCESS report based on 2 tables: tbl_task (parent) and tbl_subtask)child.
Report presentation grouped by task.
Some tasks have subtasks, then its fine. Both task and subtasks visible on the report.
Some tasks do not have subtasks. Then group is not visible on report.
Is there a way to see the group title even if its empty?

The Report Object can only group on what's in you underlying table ... if the task is not there it would be impossible to group on it.  I've done this in the past by making a table with all the possible tasks in it and creating a relation to your subtask table.  Then group on the task field in that unique listing all possible task.

Just an idea.

Typically tasks would be the main report and subtasks would be a subreport.  If you are using only a main report make sure that the join between tasks and subtasks is a left join.  That will return tasks even if they don't have subtasks.

Good day,

What is "left join"? I did not catch:(

Join you tables such that all records from the tasks table are included even if there is no matching subtasks.  That's what I was referring to in my original post.  You don't want to join where the join field i.e. TaskID has to be present in both tables.

The default join type is INNER.  With an inner join only rows from tableA that have a matching row in tableB are selected.  The other join type is OUTER which is broken into LEFT or RIGHT depending on your perspective.  A LEFT Join (outer is assumed), selects ALL rows from tableA and any matching rows from tableB.  So in your case you will get all tasks whether or not they have any subtasks whereas with an inner join, the query would return only tasks that have at least one subtask.  A RIGHT join is the same as a LEFT join but from the other direction.  It selects all rows in tableB and any matching rows in tableA.

I've attached a database I made that shows various join types.
