  • Query two tables from different schema

    - by Guru
    Hi- I have two different schemas in Oracle (say S1, S2). And two tables in those schemas(say S1.Table1, S2.Table2). I want to query these two tables from schema S1. Both S1 and S2 are in different databases. From DB1 - Schema S1, I want to do something like this, select T1.Id from S1.Table1 T1 , S2.Table2 T2 Where T1.Id = T2.refId I know one way of doing this would be creating a DB Link for the second schema and use it in querying. But sadly, I don't have priv to create DB link. Is there some way to do without DB link, like, in TOAD, you can compare two schema objects. But again, two schema objects and it is general comparision. Not like querying them. Any ideas, suggestions are greatly appriciated. Thanks in advance.

  • Multi join query returns to many results and improperly matched

    - by Woot4Moo
    I have the following minimal schema in Oracle: http://sqlfiddle.com/#!4/c1ed0/14 The queries I have run yield too many results and this query: select cat.*, status.*, source.* from cats cat, status status, source source Left OUTER JOIN source source2 on source2.sourceid = 1 Right OUTER JOIN status status2 on status2.isStray =0 order by cat.name will yield incorrect results. What I am expecting is a table that looks like the following however I cannot seem to come up with the correct SQL. NAME AGE LENGTH STATUSID CATSOURCE ISSTRAY SOURCEID CATID Adam 1 25 null null null 1 2 Bill 5 1 null null null null null Charles 7 5 null null null null null Steve 12 15 1 1 1 1 1 In plain English what I am looking for is to return all known cats + their associated cat source + their cat status while retaining null values. The only information I will have is the source that I am curious about. I also only want the cats that have a status of either STRAY or UNKNOWN (null)

  • Nhibernate Complex Type binding

    - by user329983
    I have two oracle user defined types: Audit_Type – A normal object with two fields a string and a number Audit_Table_Type – A table of audit_types, (an array) I have a stored procedure that takes as a parameter an Audit_Table_Type. List<Audit_Type> table = new List<Audit_Type>(); var query = session.CreateSQLQuery("call Audit_Rows(Audit_Table_Type(:table))") .SetParameterList("table", table, NHibernateUtil.Custom(typeof(AuditTypeUDT))) This is what I did intuativly created the ICompositeType and just set in a list of them in but this gives me nothing close to what I wanted. I couldn’t figure out how to bind to a table at all. I have built the inline sql that would do this for me but it would destroy my shared pool (not using binds). So a General question how do I bind to complex/composite types using Nhibernate?

  • Writing OLAP SQL query

    - by user1859596
    I have a project I am working on that requires the following : create a normalized sample rdbms (5 tables) using Java I entered 1 million rows of data to each table run two OLTP and two OLAP queries on the normalized tables. Denormalized tables. run the same OLTP and OLAP queries on them and compare time. What does OLAP query mean? I've searched the internet and all that I can find is that I have to make a cube, and apply queries on it. How can I write an OLAP query on a RDBMS? I have a sample : tables normalized(orders,product,customer,branch,sales) sales : order_id,product_id,quantity product : product_id,name,description,price,sales_tax customer : customer_id,f_name,l_name,tel_no,addr,nic,city branch : branch_id,name,tel_no,addr,city orders : order_id,customer_id,order_date,branch_id I want to write an OLAP query on the above tables. I am using Oracle Express with SQL Developer.

  • Is there such a thing as a dektop application event aggregator, similar to that used in Prism?

    - by brownj
    The event aggregator in Prism is great, and allows loosely coupled communication between modules within a composite application. Does such a thing exist that allows the same thing to happen between standalone applications running on a user's desktop? I could imagine developing a solution that uses WCF with TCP binding and running inside Windows Process Activation Service. Client applications could subscribe or publish events to this service as required and it would ensure all other listeners get notified of events as appropriate. Using TCP would enable event messages to be pushed out to clients without the need for polling, ensuring messages are delivered very quickly. I can't help but think though that such a thing would already exist... Is anyone aware of something like this, or have any advice on how it may be best implemented?

  • database row/ record pointers

    - by David
    Hi I don't know the correct words for what I'm trying to find out about and as such having a hard time googling. I want to know whether its possible with databases (technology independent but would be interested to hear whether its possible with Oracle, MySQL and Postgres) to point to specific rows instead of executing my query again. So I might initially execute a query find some rows of interest and then wish to avoid searching for them again by having a list of pointers or some other metadata which indicates the location on a database which I can go to straight away the next time I want those results. I realise there is caching on databases, but I want to keep these "pointers" else where and as such caching doesn't ultimately solve this problem. Is this just an index and I store the index and look up by this? most of my current tables don't have indexes and I don't want the speed decrease that sometimes comes with indexes. So whats the magic term I've been trying to put into google? Cheers

  • How to use SQL trigger to record the affected column's row number

    - by Freeman
    I want to have an 'updateinfo' table in order to record every update/insert/delete operations on another table. In oracle I've written this: CREATE TABLE updateinfo ( rnumber NUMBER(10), tablename VARCHAR2(100 BYTE), action VARCHAR2(100 BYTE), UPDATE_DATE date ) DROP TRIGGER TRI_TABLE; CREATE OR REPLACE TRIGGER TRI_TABLE AFTER DELETE OR INSERT OR UPDATE ON demo REFERENCING NEW AS NEW OLD AS OLD FOR EACH ROW BEGIN if inserting then insert into updateinfo(rnumber,tablename,action,update_date ) values(rownum,'demo', 'insert',sysdate); elsif updating then insert into updateinfo(rnumber,tablename,action,update_date ) values(rownum,'demo', 'update',sysdate); elsif deleting then insert into updateinfo(rnumber,tablename,action,update_date ) values(rownum,'demo', 'delete',sysdate); end if; -- EXCEPTION -- WHEN OTHERS THEN -- Consider logging the error and then re-raise -- RAISE; END TRI_TABLE; but when checking updateinfo, all rnumber column is zero. is there anyway to retrieve the correct row number?

  • Is there a combination of "LIKE" and "IN" in SQL?

    - by Techpriester
    Hi folks. In SQL I (sadly) often have to use "LIKE" conditions due to databases that violate nearly every rule of normalization. I can't change that right now. But that's irrelevant to the question. Further, I often use conditions like WHERE something in (1,1,2,3,5,8,13,21) for better readability and flexibility of my SQL statements. Is there any possible way to combine these two things without writing complicated sub-selects? I want something as easy as WHERE something LIKE ('bla%', '%foo%', 'batz%') instead of WHERE something LIKE 'bla%' OR something LIKE '%foo%' OR something LIKE 'batz%' I'm working with MS SQl Server and Oracle here but I'm interested if this is possible in any RDBMS at all.

  • How to count toggled buttons in jqueryui after a click event.

    - by SystemicPlural
    I need to count how many buttons are toggled using the jqueryui checkbox button option - .buttonset(). This needs to happen when a button is toggled. I added a unique class to the labels before applying the button set and have set a click event on it. It fires fine, however it is firing before the jqueryui has processed the click so the result is out of date. How do I apply the click event after jqueryui has done its job? $(".button-set").click(function(){ var selected = $("#offer_list_4 label[aria-pressed=true]").length; // out of date });

  • Accessing inter-schema tables and relations in hibernate

    - by nitesh
    There is a typical situation being faced where different tables are scattered through different schemas in Oracle database and they are related to each other (encompassing all different types of relations). How can they be represented in Hibernate using annotations as when a sessionfactory handle is created for one schema, tables in that schema can't access other related tables (foreign key relation to tables in other schema)? For a query like following, exception is thrown - "from table1 as model where model.table2Name.table2column = "+foo Exception comes as - org.hibernate.QueryException: could not resolve property: table2column of: com.test.table1 [from com.test.table1 as model where model.table2Name.table2column = 1] Here table1 and table2 are present in different schemas.

  • Alter multiple tables' columns length

    - by gdoron
    So, we just found out that 254 tables in our Oracle DBMS have one column named "Foo" with the wrong length- Number(10) instead of Number(3). That foo column is a part from the PK of the tables. Those tables have other tables with forigen keys to it. What I did is: backed-up the table with a temp table. Disabled the forigen keys to the table. Disabled the PK with the foo column. Nulled the foo column for all the rows. Restored all the above But now we found out it's not just couple of tables but 254 tables. Is there an easy way, (or at least easier than this) to alter the columns length? P.S. I have DBA permissions.

  • How can I get jquery .val() AFTER keypress event?

    - by werner5471
    I got: $(someTextInputField).keypress(function() { alert($(this).val()); }); Now the alert always returns the value BEFORE the keypress (e.g. the field is empty, I type 'a' and the alert gives me ''. Then I type 'b' and the alert gives me 'a'...). But I want the value AFTER the keypress - how can I do that? Background: I'd like to enable a button as soon as the text field contains at least one character. So I run this test on every keypress event, but using the returned val() the result is always one step behind. Using the change() event is not an option for me because then the button is disabled until you leave the text box. If there's a better way to do that, I'm glad to hear it!

  • [SQL] Getting the sum of several columns from two tables

    - by romaintaz
    I want to get the sum of several columns from 2 different tables (these tables share the same structure). If I only consider one table, I would write this kind of query: SELECT MONTH_REF, SUM(amount1), SUM(amount2) FROM T_FOO WHERE seller = XXX GROUP BY MONTH_REF; However, I would like to also work with the data from the table T_BAR, and then have a select query that return the following columns: MONTH_REF SUM(T_FOO.amount1) + SUM(T_BAR.amount1) SUM(T_FOO.amount2) + SUM(T_BAR.amount2) everything grouped by the value of MONTH_REF. Note that a record for a given MONTH_REF can be found in one table but not in the other table. In this case, I would like to get the sum of T_FOO.amount1 + 0 (or 0 + T_BAR.amount1). How can I write my SQL query to get this information? For information, my database is Oracle 10g.

  • YUI Image Loader Images Above Fold Not Loading Until Scroll event.

    I have a function that is called on the window.onload event to create a group of images and render via the scroll event. function LoadImages(){ var foldGroup = new YAHOO.util.ImageLoader.group(window, 'scroll'); for(var i=0; i<someCounter; i++){ var locationId = locationsArr[i]; foldGroup.registerSrcImage('Location_' + locationId, GetImageDomain()+'/templates/Includes/imagehandler.ashx?locationId=' + locationid); } foldGroup.foldConditional = true; foldGroup.addTrigger(window, 'resize'); } The problem I'm having is that when the page loads, the images "above the fold" are not rendered until I scroll. Is there any tips on troubleshooting this? I'm totally not a js/frontend guy :) Thanks in advance!

  • Create an event to recognise when text on a page changes?

    - by DaveDev
    There's a page that I'm trying to trigger a jQuery event for when a certain span's value changes to 1. There's a countdown timer on the page. When the timer reaches 1, I'd like to trigger a click event. The difficulty I'm having is getting a script that i'm running via Jash to know when the timer changes to 1. The value of the timer can read with: $('#tCounter_474754 .bid_time_highlight').text(); But how can I get jQuery to trigger the click when this timer reaches 1?

  • Which .NET data provider?

    - by worlds-apart89
    I am new to database programming, so I'd like help getting on the right track. I have read that there are Microsoft-defined and third-party data providers for data access. MSDN has information on data providers for SQL Server, OLE DB, ODBC, Oracle, as well as the EntityClient provider (Entity Framework). Which data provider is today's hottest, most-widely used model? Which one is the future? Also, I have seen Linq to SQL tutorials, but what category does L2S fall into?
