String formatting in MySQL - mysql
Is there a printf()-like formatting in MySQL?
I couldn't find a straightforward way in the documentation.
For example, how can I make something like:
SELECT STRFORMATFUNCTIONIMLOOKINGFOR("%03d", 17)
to get 017 ?
for your example, you could use
SELECT LPAD(17, 3, '0');
there is also
SELECT FORMAT(17, 3); -- 17.000
otherwise, UDF as mentioned above.
Maybe it will be useful:
select lpad(1, 2, '0') str;
+-----+
| str |
+-----+
| 01 |
+-----+
select lpad(11, 2, '0') str;
+-----+
| str |
+-----+
| 11 |
+-----+
see FORMAT() function:
mysql> SELECT FORMAT(12332.123456, 4);
returns '12,332.1235'
but it's only for formatting float numbers.

-- Função para formatar strings.
-- Exemplo: select mask("0123456789","(##) ####-####");
-- Retorna: (01) 2345-6789
CREATE FUNCTION mask(texto VARCHAR(255), mascara VARCHAR(255)) RETURNS VARCHAR(255) CHARSET latin1
Begin
-- Contém o texto processado.
DECLARE textoProcessado VARCHAR(255);
SET textoProcessado = "";
-- Se tem Texto.
IF length(texto) > 0 THEN
-- Percorre a máscara enquanto seu tamanho for maior que zero.
WHILE Length(mascara) > 0 DO
-- Se o caracter é um curinga.
IF LEFT(mascara,1) = "#" THEN
-- Concatena o primeiro caracter do texto.
SET textoProcessado = concat(textoProcessado,LEFT(texto,1));
-- Elimina o primeiro caracter da máscara.
SET mascara = SUBSTRING(mascara,2,255);
-- Elimina o primeiro caracter do texto.
SET texto = SUBSTRING(texto,2,255);
ELSE
-- Concatena o primeiro caracter da máscara.
SET textoProcessado = concat(textoProcessado,LEFT(mascara,1));
-- Elimina o primeiro caracter da máscara.
SET mascara = SUBSTRING(mascara,2,255);
END IF;
END WHILE;
END IF;
RETURN trim(textoProcessado);
END
You can implement this kind of function by creating a new UDF (user defined function).E.g. see http://dev.mysql.com/doc/refman/5.1/en/adding-functions.html

error about negative ou NA values in a array when using absolute values

I thought that maybe it's because the for loop might be trying to calculate NA values, but even so, how do I fix that?

how to format mysql float into sytem local values or decimal comma for a reportlab billing system
I have a Reportlab form for a billing system and it works good. But what I want to get are the values in sytem local values, with decimal comma, or separator; something as next instead as shown in the picture: 1,350,000.00 I'd like something like FORMAT in MySQL, but the problem with this one is that it does'nt let me to sum the values to get the total because it returns the values as string.

It seems that the 'grouping separator' is incorrect? Meanwhile, will 'es' (instead if 'es_CO') work correctly enough?
As some guys suggested, what I had to do was: sum the values, which was already done in my code, add a new variable appling a format with 'locale.format', and then just place that variable in the corresponding place in the reportlab form. For the total value it was not necessary to create a new variable, but just apply locate. So, I added to my code something like this: for i in dato2: #... renta = i[5] #New var to show value with thousands separator in the form renta1 = locale.format("%d", renta, grouping=True) tipo = i[9] #SI ARREND ES NATURAL(1) if tipo == 1: tipo = 0 #New var to show value with thousands separator in the form tipo1 = locale.format("%d", tipo, grouping=True) #SI ARREND ES JURÍDICO(2) if tipo == 2: tipo = renta*ivajuridi/100 #New var to show value with thousands separator in the form tipo1 = locale.format("%d", tipo, grouping=True) total = locale.format("%d", renta+tipo, grouping=True) #REPORTLAB FORM TABLA 3 data=[[desc, '', vlr], #0 [concepto, '', renta], #1 ['', '', ''], #2 ['', '', ''], #3 ['', '', ''], #4 ['', '', ''], #5 ['', '', ''], #6 ['Observaciones', 'SUBTOTAL', renta], #7 ['', 'IVA', tipo], #8 [resolucion, 'TOTAL', total]] #9
Octave - Call to m file and variables
I have condition.m, and it has inside it a loop that calculates the condition number of a user asked matrix: if(p == 1) for i = 1:co for j = 1:li somacolunas(j) = somacolunas(j) + A(j,i); end end for i = 1:co for j = 1:li somacolunasinvA(j) = somacolunasinvA(j) + abs(invA)(j,i); end end % encontrar o valor máximo maxco = somacolunas(1); for i = 1:length(somacolunas) if somacolunas(i) > maxco maxco = somacolunas(i); end end maxcoinv = somacolunasinvA(1); for y = 1:length(somacolunasinvA) if somacolunasinvA(y) > maxcoinv maxcoinv = somacolunasinvA(y); end end printf('o número de condição segundo a norma 1 é: %3.2f\n', maxco * maxcoinv); I want to call the condition.m file inside another m.file (that is in the same directory) and make use of the output vars (maxco and maxcoinv) to do some other math. I know that i can do condition; inside the other m file to access the condition.m file. But how to get access to it's variables, and if i need pass values to condition.m for loop iterate? Any ideas for the best method?
