We have a following code in Python
def function1()
...........
raise Exception ..
...............
return 0
Robot script:
${STATUS}= function1
Can anyone please let me know how in Robot script we can catch the return code / exception and branch accordingly?
Run Keyword And Return Status will return a boolean true/false did the enclose keyword succeed.
Run Keyword And Ignore Error returns a tuple of two values - the 1st is the string "PASS" or "FAIL" depending did your keyword succeed or not; the second - the keyword's return value if it passed, or any error messages if not.
Thus surround your keyword with one of these 2 - it really boils down to do you care about the returned value in success or the error in failure - and work with the returned values.
${passed}= Run Keyword And Return Status function1
Run Keyword If ${passed} Action When Passed ELSE Different Action
${rc} ${msg} Run Keyword And Ignore Error function1
Run Keyword If "${rc}" == 'PASS' Log The keyword returned the value: ${msg}
... ELSE Log The keyword failed with the message: ${msg}
So, I am trying to read and write into a file.
While writing into the file, I need to check if a particular index exist in file then I don't write and throw error.
The data in file will look like this:
{1,{data,dcA,1}}.
{2, {data, dcA, 2}}.
{3,{data,dcA,3}}.
I added the dot at the end of each line because file:consult() needs the file like this.
Which is in this format.
{Index, {Data, Node, Index}}
When I have to add a new file, I check with this Index.
Here's what I have tried so far - https://pastebin.com/apnWLk45
And I run it like this:
193> {ok, P9} = poc:start(test1, self()).
{ok,<0.2863.0>}
194> poc:add(P9, Node, {6, data}).
In poc:add/3, P9 is the process id from the file:open.
I defined before in shell as dcA
And the third is the data - which is in this format - {Index, data}
Since I am using file:consult/1, it takes the filename as parameter. At that point, I only have process id. So I take the name from
file:pid2name(_Server).
This runs perfectly when I run it for the first time.
When I run this again - poc:add(P9, Node, {6, data2}), I get an error in this line file:pid2name(_Server).
exception error: no match of right hand side value undefined
How can I solve this issue?

A DETS table can easily do what you want:
-module(my).
-compile(export_all).
open_table() ->
dets:open_file(my_data, [{type, set}, {file, "./my_data.dets"}]).
close_table() ->
dets:close(my_data).
clear_table() ->
dets:delete_all_objects(my_data).
insert({Key, _Rest}=Data) ->
case dets:member(my_data, Key) of
true -> throw(index_already_exists);
false -> dets:insert(my_data, Data)
end.
all_items() ->
dets:match(my_data, '$1').
In the shell:
~/erlang_programs$ erl

When a process opens a file, it becomes linked to a process that handles the file I/O, which means that if the process that opens the file terminates abnormally, the I/O process will also terminate. Here is an example:
-module(my).
-compile(export_all).
start() ->
{ok, Pid} = file:open('data.txt', [read, write]),
spawn(my, add, [Pid, x, y]),
exit("bye").
add(Pid, _X, _Y) ->
timer:sleep(1000), %Let start() process terminate.
{ok, Fname} = file:pid2name(Pid),
io:format("~s~n", [Fname]).
In the shell:
1> c(my).
my.erl:2: Warning: export_all flag enabled - all functions will be exported
{ok,my}
2> my:start().
** exception exit: "bye"
in function my:start/0 (my.erl, line 7)

Error in process <0.72.0> with exit value:

According to the pid2name() docs:
pid2name(Pid) -> {ok, Filename} | undefined
the function can return undefined, which is what the error message is saying happened.
I keep getting this error when trying to compile
[Error] PLS-00201 (159: 25): PLS-00201: identifier 'DMBS_UTILITY.FORMAT_ERROR_BACKTRACE' must be declared
Here's the faulty code:

As Gurwinder stated, you just have a typo in your code (DMBS_UTILITY instead of DBMS_UTILITY):
Try this:
EXCEPTION
WHEN OTHERS THEN
DBMS_OUTPUT.PUT_LINE('STUDENT:'||V_STUDENT||
'Error Occured: '||SQLERRM ||CHR(10)||'['||
DBMS_UTILITY.FORMAT_ERROR_BACKTRACE||']');

comment 1:we did remap_tablespace because we wrongly put the schema on system tablespace,
comment 2:we run this code on one computer and it worked but it is not working on other computer
Please guide me...
It seems the datamining user does not exist. Please create it and retry the import.

When invoking a custom command, I noticed that only the logs are displayed. For example, if my Custom Comand script contains a retrun statement return "great custom command", I can't find it in the result. Both in API Java client or shell execution cases.
What can I do to be able to retrieve that result at the end of an execution?
Thanks.
Command definition in service description file:
customCommands ([
"getText" : "getText.groovy"
])
getText.groovy file content:
def text = "great custom command"
println "trying to get a text"
return text
Assuming that you service file contains the following :
customCommands ([
"printA" : {
println "111111"
return "222222"
},
"printB" : "fileB.groovy"
])
And fileB.groovy contains the following code :
println "AAAAAA"
return "BBBBBB"
Then if you run the following command : invoke yourService printA
You will get this :
Invocation results:
1: OK from instance #1..., Result: 222222
invocation completed successfully.
and if you run the following command : invoke yourService printB
You will get this :
Invocation results:
1: OK from instance #1..., Result: AAAAAA
invocation completed successfully.
So if your custom command's implementation is a Groovy closure, then its result is its return value.
And if your custom command's implementation is an external Groovy file, then its result is its last statement output.
HTH,
Tamir.
