• Google maps spatial reference system

  - by JavaRocky

  What is Google map's spatial reference system using when you enter a lat, long into the maps search bar? I've found hints that it might be WGS84 but after converting to that coordinate system, nothing shows up when i paste the coordinates into the google maps search box. I am converting from GDA MGA 56. Sample: Input MGA56 coords: 336301, 6253363 Expected WGS86 coords: -33.8473340793201, 151.230631835944 I get: 16834916.928327594 -4008321.1020318186 Spatial coord systems: EPSG:28356 for MGA56 EPSG:900913 for WGS86 (google maps) I am using geotools to do the transform: CoordinateReferenceSystem crsMga56 = CRS.parseWKT(mga56); CoordinateReferenceSystem crsGmaps = CRS.parseWKT(gmaps); Coordinate coordinate = new Coordinate(336301, 6253363); Point point = new GeometryFactory().createPoint(coordinate); MathTransform transform = CRS.findMathTransform(crsMga56, crsGmaps); Geometry geometry = JTS.transform(point, transform); I know the transform is not correct, as when i use an online tool it gives me the correct coords. http://www.environment.gov.au/cgi-bin/transform/mga2geo%5Fgda.pl?east=336301&north=6253363&zone=56

• How can match end-of-line multiple times in a regex without interpolation?

  - by harschware

  Hi, if I have a input with new lines in it like: [INFO] xyz [INFO] How can I pull out the xyz part? I tried a pattern like /^\[INFO\]$(.*?)$\[INFO\]/ms, but perl gives me: Use of uninitialized value $\ in regexp compilation at scripts\t.pl line 6. I've been trying things to get interpolation to stop like using qr// but alas, no love. EDIT: The key is that the end-of-line anchor is a dollar sign but at times it may be necessary to intersperse the end-of-line anchor through the pattern. If the pattern is interpolating then you might get problems such as uninitialized $\. For instance an acceptable solution here is /^\[INFO\]\s*^(.*?)\s*^\[INFO\]/ms but that does not solve the crux of the first problem. I've changed the anchors to be ^ so there is no interpolation going on, and with this input I'm free to do that. But what about when I really do want to reference EOL with $ in my pattern? How do I get the regex to compile?

• How to stop Javascript from showing default image and only text for link?

  - by tokyowp

  The Javascript below has a default image, but I would like display text "only text url" for this link instead of this button at this link http://developer.mixi.co.jp/wp-content/uploads/2010/09/bt_check_1.gif that this script defaults to.

• File::GlobMapper doesnt seem to be exporting globmap

  - by justintime

  The following is pretty well copied from the documentation. use File::GlobMapper qw( globmap ); for my $pair (globmap '<*.tar.gz>' => '<#1.tgz>' ) { } And it gives String found where operator expected at globmapper_test1.pl line 4, near "globmap '<*.tar.gz>'" (Do you need to predeclare globmap?) (Using ActivePerl 5.10.0 on Windows) Side questions - if GlobMapper only exports one function, why is it set so you have to export it explicitly?

• Single Large v/s Multiple Small MySQL tables for storing Options

  - by Prasad

  Hi there, I'm aware of several question on this forum relating to this. But I'm not talking about splitting tables for the same entity (like user for example) Suppose I have a huge options table that stores list options like Gender, Marital Status, and many more domain specific groups with same structure. I plan to capture in a OPTIONS table. Another simple option is to have the field set as ENUM, but there are disadvantages of that as well. http://www.brandonsavage.net/why-you-should-replace-enum-with-something-else/ OPTIONS Table: option_id <will be referred instead of the name> name value group Query: select .. from options where group = '15' - Since this table is expected to be multi-tenant, the no of rows could grow drastically. - I believe splitting the tables instead of finding by the group would be easier to write & faster to execute. - or perhaps partitioning by the group or tenant? Pl suggest. Thanks

• A Perl script and a Perl module are using `use lib` and referencing the same module

  - by miss_a

  I have a Perl script that is using two modules. The first module also uses the second module. If the the first module does use lib 'dir1', and the script does use lib 'dir2': module1.pm use lib "dir1"; use module2; script.pl use lib "dir2"; use module1; use module2; which directory is being used by the first module? Does the script's use lib, 'dir2' override the use lib, 'dir1' in the first module, or do they have different scope?

• How can I check a type's dependents order to drop them and replace/modify the initial type?

  - by pctroll

  I tried to modify a type using the following code and it gave me the error code: 'ORA-02303'. I don't know much about Oracle or PL/SQL but I need to solve this; so I'd appreciate any further help with this. Thanks in advance. The code is just an example. But then again, I need to check its dependents first. create or replace type A as object ( x_ number, y_ varchar2(10), member procedure to_upper ); /

• Prolog - Finding the current directory, relative directory for 'tell' predicate

  - by Bharat

  I'm having trouble trying to figure out how to get prolog to spit out a text file where I want it to. I'm currently doing a bunch of operations and then using tell('output.txt') to record the output. Now the problem is that when I do this, it creates this file in the SWI \bin\ folder. I was wondering if there's a way to make it create this file in the directory containing the actual .pl file. So even if the file was moved (and it will be), the text file gets created right where the source file is. Long story short, is there a way to get the location of the source file once the source file has been consulted? Many Thanks!

• Oracle XE + ODP.NET ANNOYING VIEW ERROR

  - by Alex

  Sup guys, heres my view: CREATE OR REPLACE VIEW SISTEMA.VWTELA AS SELECT TEL_DLTELA AS Tela, TEL_DLDESCRICAO As Descricao, TEL_DLTABELA As Tabela, CASE WHEN to_char(TEL_STATIVO) = to_char(1) THEN to_char('Yes') ELSE to_char('No') END as Ativo, TEL_IDTELA AS IDTEL FROM SISTEMA.TEL_TELA; When i do a SELECT * FROM SISTEMA.VWTELA it works fine from PL/SQL Developer but when i launch the query from my VB.NET application it throws me a super annoying error ORA-01722. Any ideas? The Application code works perfecty with any query so its not application code error but prolly some "super cool feature" from ODP.NET. Already tried to_number, to_whatever and same error always happens.

• Oracle - correlated subquery problems

  - by FrustratedWithFormsDesigner

  I have this query: select acc_num from (select distinct ac_outer.acc_num, ac_outer.owner from ac_tab ac_outer where (ac_outer.owner = '1234567') and ac_outer.owner = (select sq.owner from (select a1.owner from ac_tab a1 where a1.acc_num = ac_outer.acc_num order by a1.a_date desc, a1.b_date desc, a1.c_date desc) sq where rownum = 1) order by dbms_random.value()) subq order by acc_num; The idea is to get all acc_nums (not a primary key) from ac_tab, that have an owner of 1234567. Since an acc_num in ac_tab could have changed owners over time, I am trying to use the inner correlated subqueries to ensure that an acc_num is returned ONLY if it's most recent owner is 12345678. Naturally, it doesn't work (or I wouldn't be posting here ;) ) Oracle gives me an error: ORA-000904 ac_outer.acc_num is an invalid identifier. I thought that ac_outer should be visible to the correlated subqueries, but for some reason it's not. Is there a way to fix the query, or do I have to resort to PL/SQL to solve this? (Oracle verison is 10g)

• oracle plsql: retrieve runtime parameter values when you call a procedure

  - by Luca Vaccaro

  I need a generalized method to get list of runtime parameters (values) when I call a procedure. I need something similar to the $$PLSQL_UNIT that returns the name of the running procedure. (plsql Oracle 10g) E.g. look at this sample procedure: (it simply prints its own name and parameters ) CREATE OR REPLACE PROCEDURE MY_PROC(ow in varchar2, tn IN varchar2) IS BEGIN dbms_output.put_line('proc_name: '||$$PLSQL_UNIT||' parameters: '|| ow||' '||tn ); EXCEPTION WHEN OTHERS THEN DBMS_OUTPUT.PUT_LINE('ERRORE: ' ||SQLERRM); END MY_PROC; / Running procedure produces the following output: SQL> 1 BEGIN 2 IBAD_OWN.MY_PROC('first_par', 'second_par'); 3 END; 4 / proc_name: MY_PROC parameters: first_par second_par PL/SQL procedure successfully completed. I'm not satisfy because I can't copy and paste in all my procedures because I have to hard code each procedure to set their right parameter variables. Thanks in advance for the help.

• pipelined function

  - by user289429

  Can someone provide an example of how to use parallel table function in oracle pl/sql. We need to run massive queries for 15 years and combine the result. SELECT * FROM Table(TableFunction(cursor(SELECT * FROM year_table))) ...is what we want effectively. The innermost select will give all the years, and the table function will take each year and run massive query and returns a collection. The problem we have is that all years are being fed to one table function itself, we would rather prefer the table function being called in parallel for each of the year. We tried all sort of partitioning by hash and range and it didn't help. Also, can we drop the keyword PIPELINED from the function declaration? because we are not performing any transformation and just need the aggregate of the resultset.

• How to have tortoisesvn Always freeze svn:externals for tags

  - by dnndeveloper

  Is this possible with tortoiseSVN?: Always freeze svn:externals for tags the scenario is our trunk will always use the 'head' revision for externals, however when we create 'tags' we would like for them to have a revision set for externals to properly 'freeze' them at a specific point in time. Thanks! Update Thanks to everyone for your feedback/info. Since I could not find anything that would completely meet our needs (tried smartsvn and svncopy.pl) I made a console app that so far has passed all our test cases. A high level overview: The app takes a repository URL then looks for all externals and adds the last commit revision for them - I do a "svn info" and get the "commit revision". The app works with both folder and single file externals. Here is the source code and complete setup files: http://svnxf.codeplex.com/

• mod_perl memory leak

  - by marghi

  Hello, I recently discovered that one of our sites has a memory leak in it, it's very strange because it happened all of the sudden. I've used GTop to measure the memory size per process and it tells me that the real value is somewhere around 65 MB (on the server) per request and and additional 5 MB shared. I tried preloading the modules in the startup.pl file a indicated in the performance tuning article for mod_perl. Nothing happened if fact the shared memory decreased down to 3.7 MB, in this situation I thought that my application is leaking memory do before any line of code got executed I measured the memory just to find out that the total value is in fact 64 MB, my questions are: Is there a default preallocation of memory for each process? Is there a configuration issue? Is mod_perl leaking memory ? Thank you very much.

• Difference in select for update of ... in Oracle Database 10g and 11g

  - by sax

  Hi, I found out that Oracle Database 10g and 11g treat the following PL/SQL block differently (I am using scott schema for convenience): DECLARE v_ename bonus.ename%TYPE; BEGIN SELECT b.ename INTO v_ename FROM bonus b JOIN emp e ON b.ename = e.ename JOIN dept d ON d.deptno = e.deptno WHERE b.ename = 'Scott' FOR UPDATE OF b.ename; END; / While in 10g (10.2) this code ends successfully (well NO_DATA_FOUND exception is raised but that is expected), in 11g (11.2) it raises exception "column ambiguously defined". And that is definitely not expected. It seems like it does not take into account table alias because I found out that when I change the column in FOR UPDATE OF e.empno (also does not work) to e.mgr (which is unique) it starts working. So is this some error in 11g? Any thoughts?

• A datastructure for Robotic Sort

  - by amit.codename13

  I am trying to solve this problem : https://www.spoj.pl/problems/CERC07S/ I have identified that i need a datastructure in which reversing operations have lesser time complexity. I tried to create one using a doubly linked list, in which (i thought) reversing can be done in O(1) by just changing a value associated with the starting and ending node which indicates the direction of traversing the list. I tried to implement it but got stuck. Maybe the approach is wrong! Are trees applicable here? If yes, how? Any ideas or links are appreciated? Thanks in advance.

VARIABLE area NUMBER DECLARE radius NUMBER(2) := &s_radius; pi CONSTANT NUMBER := 3.14; BEGIN :area := pi * radius * radius; END; I understand that I can run this using SqlPlus, but I remember my teacher was running this from the web browser using Application Express.

Can you help me run it in Application Express or point me to a way where I can use an editor to run these course exercises? Thanks!
