Hi,
I want to make a matrix report with there specifications:
Two details tables (t1,t2) are connected through the master table (t)
The matrix consist of:
rows: t1.d1
columns: t2.d2
cells: count(*)

SQL main features:
t.td1=t1.d1 and t.td2=t2.d2
There is IN operator
Group by t1.d1,t2.d2

The problem is:
suppose that t1.d1 has value let it b, and there is no row in the master has that value, then the report will dicard it and will not calculate the count which has the value 0,the same is true in case of values in t2.d2.So the report will have empty cells,and some columns and rows may not be shown if all cells in that row or column are empty.

The problem is :I tried the plus sign to make outer join but it is usless.

Hope that I could explain my problem good.
May any one help me. Thanks a lot in advance

you can create two queries in your data model

Query 1 - to get all of the combinations of rows and columns to make the matrix: ie. rows = departments and columns = years.

Query 2 - to get the hours worked and number of employees to fill the cells in the matrix.

The matrix will be laid out to have every year and department in query 1 regardless of whether there are employees or hours worked in query 2.
