Hi
I have a table
TAB1 with data
no name
1 abc
2 abc
3 xyz
4 xyz
5 cvb
now I would like to create a form with name counts as
abc 2
xyz 2
cvb 1
I would like to create a datablock to display all the unique names, not sure where I should be writing the query to display unique names. I would like to create a textitem box to display the counts when the form is compiled, but not sure which trigger to use to write the query.please help

The simplest way to do that is to create a view:

create view v_tab1 as
  select name, count(*) cnt
  from tab1
  group by name

and base your form's data block on that view.

[EDIT] Whoa! Forgot the GROUP BY clause! Thank you, @uzairawan, for pointing that out!

This is a simple GROUP BY query by which you can retrieve aggregate SUM, COUNT and AVG of any numeric field. For example :

select deptno, count(empno) from emp
group by deptno
