interval between rows in the same column / intervalo entre filas de la misma columna

[#1]

Buenos días, necesito restar datos entre filas, es decir de una misma  columna.

Hello, I need to subtract dates between rows, ie the same column.

Name	Time	State	Code
Person 1	01/01/2011  8:16:11	Logged - in	0
Person 1	01/01/2011  16:00:11	Logout	130

"Time"= 01/01/2011 16:00:11 - 01/01/2011 08:16:11 = 07:44:00

Hi,

I think you can try chart inter record functions like above, i.e. like this

= interval(Time- above(Time))

as expression in your chart. This will show the time difference between current and above row, for each row in your table.

Hope this helps,

Stefan

ahora se complica un poco mas porque necesito condiciones.

now a little more complicated because I need conditions.

Name	Time	State	Code
Person 1	01/01/2011  8:16:11	Logged - in	0
Person 1	01/01/2011  16:00:11	Logout	23658

Person 1                        01/01/2011  19:00:11                             ready                                   44             

Person 1                       01/01/2011  19:00:11                            Logout                                130

Necesito el intervalo de "Time", SI    "state"="Logged - in"  y  "Code"="130".

Need interval of "Time", if "state" = "Logged - in"   and   "Code" = "130"

Gracias

Thanks for your help

Hi,

to create a time difference, you need to use two rows, so given your above example

- I don't see a matching row for state=Logged in" and Code=130

- If there is a match, to what other row should the interval difference be taken? Using the previous row or the previous row which matches the condition?

Could you provide maybe a more complete data sample (as INLINE table or sample qvw file) and the exprected results?

Regards,

Stefan
