xorg touchscreen: absolute position ignored - x11
I'm trying to use an EETI EXC7200 touchscreen with X (1.14.7). The touchscreen is recognized and events are processed. TS sends absolute coordinates and evdev driver is used (mode absolute). However when I move to the edge of the screen (and X or Y reaches 0) the pointer is snapped to center of the window. Afterwards any movement has an offset (depending on the difference between real position and corner).
To test this I draw pointer on the screen with coordinates from XQueryPointer.
Here is the output from evtest:
~# evtest /dev/input/event0
Input driver version is 1.0.1

xinput is outputting extra motion events positioned at the center. But only when I get near the edge of touchscreen.
What am I doing wrong? What should I be looking at?
Thank you for any help or hints.
The cause was in SDL 1.2.15 which was used at the same time. By default it uses relative mode for mouse/touch events and apparently sends own X11 mouse events for corrections it makes ("see motion a[0]=1024 a[1]=1024").
Setting environment variable SDL_MOUSE_RELATIVE=0 fixed this behavior.

[]uint8 inteface from UUID database data type to STRING or UUID GOLANG
I have problem when return uuid type from database using interface, I geeting back []uint8 not uuid or string, here []uint8 interface data, id: [53 102 53 56 99 101 99 98 45 101 48 52 49 45 52 54 52 57 45 98 54 49 55 45 100 53 55 56 102 49 97 50 53 53 51 56] expected id: 5f58cecb-e041-4649-b617-d578f1a25538 how to convert back []uint8 interface to UUID or string thanks
If it's just a []uint8 then string(buf) will convert it. You seem to be implying that it's an interface{} though. In that case you would do string(buf.([]uint8)).
how to sort the numbers 1, ... n lexicographically without converting the numbers to string?
Assume I have input n how I can print this sequence without convert the number to string?
i.e:-
n = 100
Output :- 1 10 100 11 12 13 14 15 16 17 18 19 2 20 ...
n = 15 Output :- 1 10 11 12 13 14 15 2 3 4 5 6 7 8 9
n = 20 Output :- 1 10 11 12 13 15 15 16 17 18 19 2 20 3 4 5 6 7 8 9
What is the main factor here?
My initial solution that will print the 1's followed by 0's or 2's followed by 0's
int n = 100;
for (int i = 1; i <= n; i++) {
int x = i;
while (x <= n) {
System.out.println(x);
x *= 10;
}
}
I figured out the solution:-
You can call it with initial k = 1
for example printnum(15, 1
void printnums(int n, int k) {
if (k > n) {
return;
}
for (int i = 0; i < 10; i++) {
if (k <= n) {
System.out.println(k);
k *= 10;
printnums(n, k);
k /= 10;
k++;
if (k % 10 == 0) return;
}
}
}
I don't know if there are more optimized one?
Here a condensed solution in Python based on the OP's own answer: def genRangeLexiSorted(n, k=1): for i in range(k, min(k+10-k%10, n+1)): yield i for j in genRangeLexiSorted(n, 10*i): yield j def printnums(n): print(*list(genRangeLexiSorted(n))) Then the calls printnums(1) printnums(9) printnums(11) printnums(20) printnums(100) give the following outputs: 1 1 2 3 4 5 6 7 8 9 1 10 11 2 3 4 5 6 7 8 9 1 10 11 12 13 14 15 16 17 18 19 2 20 3 4 5 6 7 8 9 1 10 100 11 12 13 14 15 16 17 18 19 2 20 21 22 23 24 25 26 27 28 29 3 30 31 32 33 34 35 36 37 38 39 4 40 41 42 43 44 45 46 47 48 49 5 50 51 52 53 54 55 56 57 58 59 6 60 61 62 63 64 65 66 67 68 69 7 70 71 72 73 74 75 76 77 78 79 8 80 81 82 83 84 85 86 87 88 89 9 90 91 92 93 94 95 96 97 98 99

Row sum in PIVOT query
Please Help me i am trying to create pivot but not success. query select t.g_no, t.sz, t.DT, t.Qty from gp123 t Result 4480 46 4/24/2017 30 4480 42 4/24/2017 28 4480 40 4/24/2017 37 4480 44 4/24/2017 26 4480 50 4/24/2017 17 4480 48 4/24/2017 2 Required result Gate Pass No. Date 40 42 44 46 48 50 Total 4480 24-Apr-17 37 28 26 30 2 17 140 4500 25-Apr-17 187 140 155 127 99 85 793 4537 25-Apr-17 141 97 139 172 141 159 849 4538 26-Apr-17 90 141 122 148 172 151 824 4542 26-Apr-17 1 60 118 63 32 3 277
Use the SUM() OVER () analytic function to get the total and then use PIVOT to convert the rows to columns: SELECT * FROM ( SELECT g_no AS "Gate Pass No.", sz, DT AS "Date", Qty, SUM( qty ) OVER ( PARTITION BY g_no, DT ) AS Total FROM gp123 ) PIVOT ( SUM( qty ) FOR sz IN ( 40, 42, 44, 46, 48, 50 ) )
... or simply: select g_no, dt, "40", "42", "44", "46", "48", "50", "40" + "42" + "44" + "46" + "48" + "50" total from gp123 t pivot (sum(qty) for sz in (40, 42, 44, 46, 48, 50));
return resultset from function
I need to return a resultset from function and work with this resultset just like with an ordinary table.
So I need something like following:
select * from table(querydb('select * from dual'))
The querydb function should return a resultset of a query passed to it.
Can it be implemented in oracle?
Would be grateful for any information.
If you need a result set and a ref cursor won't do with a datatype called sys.anydataset. i.e what you seem to want is a pipelined function, but of course with a regular pipelined function you need to define the output structure, which in your case isn't static.
Enter anydataset. this type allows us to dynamically generate types on the fly (at hard parse time only) to allow us to define pipelined functions with varying outputs.
The coding is a bit complex unfortunately.
To start with, we define a type that will do the processing of the passed in SQL statement.

Type body created.
once this is done, you can query like:
SQL> select * from table(pkg_pipeline.querydb('select * from dual'));
D
-
X
SQL> select * from table(pkg_pipeline.querydb('select * from v$mystat where rownum <= 2'));
SID STATISTIC# VALUE
---------- ---------- ----------
230 0 1
230 1 1
If I understand you correctly, you want to do this:
select * from (select * from dual)
...with the caveat that the subquery is in some way dynamic? You can do this using a PL/SQL block, using a reference cursor:
declare
subQuery varchar2(1000);
mainQuery varchar2(1000) := 'select * from (';
type myRefCursor is ref cursor;
myResultset myRefCursor;
myField1 FIELDTYPE;
...
myFieldN FIELDTYPE;
begin
-- Generate this dynamically
subQuery := 'select * from dual';
-- Create main query and open cursor
mainQuery := mainQuery || subQuery || ')';
open myResultset for mainQuery;
-- Loop through records
loop
fetch myResultset into myField1, ..., myFieldN;
exit when myResultset%NOTFOUND;
-- Do something with the record data
dbms_output.put_line(myField1 || ' ... ' || myFieldN);
end loop;
close myResultset;
end;
/
Note that rather than using fetch into with individual variables, you can populate an entire record at once, provided you can define the record's field types. That is, if you have created a custom type or your record's type matches a table you already have in your schema. For the latter, you can use:
myRecord someTable%ROWTYPE;
...in the declaration block, then change the fetch into statement to:
fetch myResultset into myRecord;
...and access record fields using dot notation (e.g., myRecord.some_field_name).
You say in your comments that the dynamic SQL bit is from the results of some other query. Therefore, in my example code, you could use a regular cursor to loop over these data to create the subQuery variable in each instance... Although, incidentally, is there any reason why what you're trying to achieve can't be done with a simple join?
