PL/SQL Program to Print Patterns

Here you will get plsql programs to print patterns of stars, numbers and alphabets.

Pattern 1:

*
**
***
****
*****

declare
	n number:=5;
	i number;
	j number;
begin
	for i in 1..n
	loop
		for j in 1..i
		loop
			dbms_output.put('*');
		end loop;
		
		dbms_output.new_line;
	end loop;
end;
/

Pattern 2:

*****
****
***
**
*

declare
	n number:=5;
	i number;
	j number;
begin
	for i in reverse 1..n
	loop
		for j in 1..i
		loop
			dbms_output.put('*');
		end loop;
		
		dbms_output.new_line;
	end loop;
end;
/

Pattern 3:

    *
   **
  ***
 ****
*****

declare
	n number:=5;
	i number;
	j number;
	k number;
begin
	for i in 1..n
	loop
		for j in 1..n-i
		loop
			dbms_output.put(' ');
		end loop;

		for k in 1..i
		loop
			dbms_output.put('*');
		end loop;
		
		dbms_output.new_line;
	end loop;
end;
/

Pattern 4:

*****
 ****
  ***
   **
    *

declare
	n number:=5;
	i number;
	j number;
	k number;
begin
	for i in reverse 1..n
	loop
		for j in 1..n-i
		loop
			dbms_output.put(' ');
		end loop;

		for k in 1..i
		loop
			dbms_output.put('*');
		end loop;
		
		dbms_output.new_line;
	end loop;
end;
/

Pattern 5:

    *
   ***
  *****
 *******
*********

declare
	n number:=10;
	i number:=1;
	j number;
	k number;
begin
	while i<n
	loop
		j:=1;
		while j<n-i
		loop
			dbms_output.put(' ');
			j:=j+2;
		end loop;

		for k in 1..i
		loop
			dbms_output.put('*');
		end loop;
		
		dbms_output.new_line;
		i:=i+2;
	end loop;
end;
/

Pattern 6:

*********
 *******
  *****
   ***
    *

declare
	i number:=9;
	j number;
	k number;
begin
	while i>=1
	loop
		j:=9;
		while j>i
		loop
			dbms_output.put(' ');
			j:=j-2;
		end loop;

		for k in 1..i
		loop
			dbms_output.put('*');
		end loop;
		
		dbms_output.new_line;
		i:=i-2;
	end loop;
end;
/

Pattern 7:

    *
   ***
  *****
 *******
*********
 *******
  *****
   ***
    *

declare
	n number:=10;
	i number:=1;
	j number;
	k number;
begin
	while i<n
	loop
		j:=1;
		while j<n-i
		loop
			dbms_output.put(' ');
			j:=j+2;
		end loop;

		for k in 1..i
		loop
			dbms_output.put('*');
		end loop;
		
		dbms_output.new_line;
		i:=i+2;
	end loop;

	i:=7;
	
	while i>=1
	loop
		j:=9;
		while j>i
		loop
			dbms_output.put(' ');
			j:=j-2;
		end loop;

		for k in 1..i
		loop
			dbms_output.put('*');
		end loop;
		
		dbms_output.new_line;
		i:=i-2;
	end loop;	
end;
