A typical problem : urgent

Question

hi,
I m in the middle of a typical problem.
I have this table abc with columns
( x varchar2(10),
y varchar2(10),
z varchar2(10)
the contents of which look like this
table : abc
x y z
5 .5*x .1+x
10 .75*x
columns y and z r storing the formula.
now my problem is
I have another table
PQR (x number(5,2), y number(5,2), z number(5,2))
I want the result of this table to look like this
table : PQR
x y z
5 2.5 .5
10 7.5
i. e the formula should get executed and the result to be placed
in the corresponding columns of PQR.
I just hope someone comes up with the following result. I would
be very thankfull to the person.

Answer 1

If the formula is always in the fashion u mentioned in the table
ABC i.e, a number multiplied with x then do this way.
store the value of the number only in the y column and z column,
i.e, if .5*x is the formula then store .5 only in column y.
and if .1*x is the formula then store .1 only in column z.
then use a procedure to update PQR table.
the procedure can be in this way.....
Use a cursor with a select statement to retrive the values of
table ABC.
and store these values in local variable.
say LVX,LVY,LVZ
declare another 2 local variables- LVQ,LVR
and say LVQ=LVY*LVX
and LVR=LVZ*LVX
and insert into table PQR (x,y,z)
     values (LVX,LVQ,LVR);
Hope this helps u.
If u could get a solution for invoking MSWORD or Powerpoint,
please let me know.
