AW: AW: [firebird-support] Converting with parameters stored in variables?
Helle Karol, thank you, now it works and it is more easier. I have modified this: SELECT lpad(cast(TRUNC(x.a) as integer), :i_anz, '0') || '.' || lpad((X.A-TRUNC(X.A))*X.B, 3, '0') FROM (SELECT cast(:z_str as double precision) AS A, POWER(10,:i_anz2) AS B FROM RDB$DATABASE) X Without cast as integer I get the 100 to the left (100.300) (11.3), without casting as double precision, I get an error, cannot work with strings.

Hallo Karol, we have a rfc interface with a high bay storage an the telegram defines the different datatypes. If I would create a new material, I must set different parameters #name#weight…#111.111# and so on. Trunc instead of pow? Regards Olaf Von: firebird-support@yahoogroups.com Gesendet: Freitag, 30.

But i ask why do you need this format in resultset? Formatting numbers is a client side task, same as for DATE. Regards, Karol Bieniaszewski

Hello Karol,
yes, I know padding. In my case I would like to set the numeric parameters with
two variables first.
* Take the R11.3 into two variables f1 and f2 (f1 = 11, f2 = 3)
* Set the numeric(:f1,:f2) without execute statements
Now I have it realized as following:
c_anz = substring(t_str from 2 for (position( '.' in t_str)-2)); -- precision
(t_str is ’11.3’ a string)
select value_int from p_u_isnumeric(:c_anz) into :i_anz; -- check for integer
and convert into an int
c_anz2 = substring(t_str from (position('.' in t_str)+1) for 5); -- scale
select value_int from p_u_isnumeric(:c_anz2) into :i_anz2;
tmp_int = cast(z_str as double precision) * power(10,i_anz2); -- set the
value, round it –z_str = double precision, the value to convert into a string
(2.4 into 002.400)
tmp_str = lpad(cast(tmp_int as varchar(15)),i_anz + i_anz2,'0');
n_str = o_str || left(tmp_str,i_anz) || '.' || right(tmp_str,i_anz2) || '#';
-- set the decimalpoint
suspend;

Hi
This is called padding.
Simple example (but not what you want you must padd also decimal point)
SELECT LPAD(CAST(100 AS NUMERIC(10,3)), 14, '0') FROM RDB$DATABASE
But you must tell us what is your real problem, as you need padding for what?
Pozdrawiam,
Karol Bieniaszewski

select right('0'||(10.3+0.000),10) from rdb$database
Hello,
I get from a application the following
100
R10.3
Or
22.22
R10.3
Now I should take it into:
000100.000
And
22.220
I think, I cannot simply (cast :input as :vartype) (vartype = ‘decimal(10.3)’
Also it will fortunately not work: cast(input as decimal(:v1,:v2) (v1 = 10 v2 =
3).
How can I realize it without dismantle the 10.3 and the 22.22?
Thank you.
