Hi All,
Is there any way in postgres to write a query to display the result in
matrix form. (where column names are dynamic)
For eg.
Employee Name Client1 Client2 Client3 Client4
Emp1 100 102 90 23
Emp2 56 0 23 98
Emp3 34 45 76 0
Here Client1, Client2... are the values from the database.
Thanks,
Jyoti

There is a contrib-modul, tablefunc. It contains a crosstab-function.
Maybe this can help you. Other solution: write a function in plpgsql and
build a string that contains your query, and EXECUTE that string.
