What does “%Type” mean in Oracle sql?

Question

I\'m getting my first experience with Oracle and TOAD (I know SSMS). I came across this \"%Type\" next to an input parameter in an update procedure and I have no idea what it is

Answer 1

some example

set serveroutput on
DECLARE
  var1  table_a.id%TYPE;
  var2  table_a.value%TYPE;
  var3_row table_a%ROWTYPE;
BEGIN
  SELECT id,value
    INTO var1, var2
    FROM table_a
  WHERE id= 8 AND ROWNUM<=1; 

  SELECT id+100,value INTO var3_row from table_A where rownum=1;

  INSERT INTO table_a VALUES var3_row;

  dbms_output.put_line('this is a test');
  dbms_output.put_line(var1);
  dbms_output.put_line(var2);
  NULL;  -- do something useful here
EXCEPTION
  WHEN NO_DATA_FOUND THEN
    NULL;  -- do something appropriate here
  WHEN TOO_MANY_ROWS THEN
    NULL;  -- do something appropriate here
END;
