I need to save an itab as an xstring or something like this and save it in dbtab.
Later I need to gather this xstring from dbtab and convert it in the itab before with exactly the same input from before.
I tried a lot of fuba´s like:
SCMS_STRING_TO_XSTRING or SCMS_XSTRING_TO_BINARY but I didn´t find something to convert it back.
Does somebody have tried something like this before and have some samples for me ?
Unfortunately I didn´t find something on other blogs or else.
An easy solution to convert into an xstring:
CALL TRANSFORMATION id SOURCE root = it_table RESULT XML DATA(lv_xstring).
Back would be like:
CALL TRANSFORMATION id SOURCE XML lv_xstring RESULT root = it_table.
For more information, see the ABAP documentation about data serialization and deserialization by using the XSL Identity Transformation.
use
import ... from data buffer
and
export ... to data buffer
to (re)store any variable as xstring.
Or you can use
import|export ... from|to database ...
I did some methods to do this:
First I loop at the table and concatenate it into a string.
Then convert the string into an xstring.
LOOP AT IT_TABLE ASSIGNING FIELD-SYMBOL(<LS_TABLE>).
CONCATENATE LV_STRING <LS_TABLE> INTO LV_STRING SEPARATED BY CL_ABAP_CHAR_UTILITIES=>NEWLINE.
ENDLOOP.
CALL FUNCTION 'SCMS_STRING_TO_XSTRING'
EXPORTING
TEXT = IV_STRING
IMPORTING
BUFFER = LV_XSTRING.
Back would be like:
Convert xstring back to string
String into table
TRY.
CL_BCS_CONVERT=>XSTRING_TO_STRING(
EXPORTING
IV_XSTR = IV_XSTRING
IV_CP = 1100 " SAP character set identification
RECEIVING
RV_STRING = LV_STRING
).
CATCH CX_BCS.
ENDTRY.
SPLIT IV_STRING AT CL_ABAP_CHAR_UTILITIES=>NEWLINE INTO: TABLE <LT_TABLE> .
READ TABLE <LT_TABLE> ASSIGNING FIELD-SYMBOL(<LS_TABLE>) INDEX 1.
IF <LS_TABLE> IS INITIAL.
DELETE TABLE <LT_TABLE> FROM <LS_TABLE>.
ENDIF.

select from list by index ${locator_var} ${inp_msge_type}
--getting error as expected string, int found
select from list by index ${locator_var} 7
-----not getting any error
${inp_msge_type}----contains 7 from DB query the result is stored in this variable, to avoid hard coding we need to do this
Is there any way to write
Do not add links to screenshots of code, or error messages, and format the code pieces accordingly - use the ` (tick) symbol to surround them.
The rant now behind us, your issue is that the keyword Select From List By Index expects the type of the index argument to be a string.
When you called it
Select From List By Index ${locator_var} 7
, that "7" is actually a string (though it looks like a number), because this is what the framework defaults to on any typed text. And so it works.
When you get the value from the DB, it is of the type that the DB stores it with; and probably the table schema says it is int. So now you pass an int to the keyword - and it fails.
The fix is simple - just cast (convert) the variable to a string type:
${inp_msge_type}= Convert To String ${inp_msge_type}
, and now you can call the keyword as you did before.
QuotedPremium column is a string feature so I need to convert it to numeric value in order to use algorithm.
So, for that I am using Edit Metadata module, where I specify data type to be converted is Floating Point.
After I run it - I got an error:
Could not convert type System.String to type System.Double, inner exception message: Input string was not in a correct format.
What am I missing here?
As mentioned in comments, you must change column where numbers are handled as text to numeric type data and it shouldn't have any null values. Now answering the question of how to substitute NULL's in data using ML studio and converting to numeric type.
Substitute NULL's in data
Use Execute R Script module for that, and add this code in it.
dataset1 <- maml.mapInputPort(1); # class: data.frame
dataset1[dataset1 == "NULL"] = 0; # Wherever cell's value is "NULL", replace it with 0
maml.mapOutputPort("dataset1"); # return the modified data.frame
Image for same:
Convert to numeric data
As you have added in your answer, this can be done using the Edit Metadata module.
I am attempting to write an algorithm that selects a specific reference standard (vector) as a function of temperature. The temperature values are stored in a structure ( procspectra(i).temperature ). My reference standards are stored in another structure ( standards.interp.zeroed.ClOxxx ) where xxx are numbers such as 200, 210, 220, etc. I have built the rounding construct and paste it below.
for i = 1:length(procspectra);
if mod(-procspectra(i).temperature,10) > mod(procspectra(i).temperature,10);
%if mod(-) > mod(+) round down, else round up
tempvector(i) = procspectra(i).temperature - mod(procspectra(i).temperature,10);
else
tempvector(i) = procspectra(i).temperature + mod(-procspectra(i).temperature,10);
end
clostd = strcat('standards.interp.zeroed.ClO',num2str(tempvector(i)));
end
This construct works well. Now, I have built a string which is identical to the name of the vector I want to invoke, but I'm uncertain how to actually call the vector given that this is encoded as a string. Ideally I want to do something within the for-loop like:
parameters(i).standards.ClOstandard = clostd
where I actually am assigning that parameter structure to be the same as the vector I have saved in the standards structure I have previously generated (and not just a string)
Could anyone help out?
Don't construct clostd like that (containing the full variable name), make it contain only the last field name instead:
clostd = ['ClO' num2str(tempvector(i))];
parameters(i).standards.ClOstandard = standards.interp.zeroed.(clostd);
This is the syntax of accessing a structure's field dynamically, using a string. So the following three are equivalent:
struc.Cl0123
struc.('Cl0123')
fieldn='Cl0123'; struc.(fieldn)
I am tring to plot a map with d3.js using GeoJSON, but the paths generated look like this:
<path d="MNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNLNaN,NaNZ">
the code and data are in this Gist:
https://gist.github.com/4157853
I can load the data just fine on QGIS.
Does any one know what is causing this?
The way you have specified the offset in the Mercator projection doesn't seem right. The projection.translate method expects a two element array:
https://github.com/mbostock/d3/wiki/Geo-Projections#wiki-mercator_translate
So instead of:
proj.translate(-43.8,-23.2).scale(10);
you would need to say:
proj.translate([-43.8,-23.2]).scale(10);
-- edit --
See source of projection.translate: https://github.com/mbostock/d3/blob/3.0/src/geo/projection.js#L139
projection.translate = function(_) {
if (!arguments.length) return [x, y];
x = +_[0];
y = +_[1];
return reset();
};
If the argument _ is not an array then +_[0] will return a NaN and therefore the x and y will become NaNs. (This is because trying to get one element from a number (e.g. 213[0]) returns undefined and casting undefined to a number (e.g. +undefined) yields NaN.)
If the code you posted in the gist is everything you're trying to run, then the data you show in data.json is not being loaded anywhere. Anyway, your draw function is acting on the data defined by the variable map (line 16), which refers to a simulation variable which isn't set anywhere. And even if it did, line 34 then refers to a features property of the object passed in as json, which map does not have.
In summary, you need to pass the JSON you posted in the gist to your draw function. Then it might well work. If you don't pass in valid data to the d3 SVG helpers, you'll get a bunch of NaN out.
