• How to escape wildcard characters in "like" clause in HQL?

  - by Pablo Cabrera

  How can I escape the wildcard characters in a like clause? E.g.: select foo from Foo as foo where foo.bar like '%' || :filter ||'%' query.setParameter("filter", "%"); query.list(); // I'd expect to get the foo's containing the '%' in bar, not all of them! Any ideas?

• Tools to help with analysing log files

  - by peter

  I am developing a C# .NET application. In the app.config file I add trace logging as shown, <?xml version="1.0" encoding="UTF-8" ?> <configuration> <system.diagnostics> <trace autoflush="true" /> <sources> <source name="System.Net.Sockets" maxdatasize="1024"> <listeners> <add name="MyTraceFile"/> </listeners> </source> </sources> <sharedListeners> <add name="MyTraceFile" type="System.Diagnostics.TextWriterTraceListener" initializeData="System.Net.trace.log" /> </sharedListeners> <switches> <add name="System.Net" value="Verbose" /> </switches> </system.diagnostics> </configuration> Are there any good tools around to analyse the log file that is output?

• Spring.NET and ADO.NET Entity Data Model

  - by Jason

  Having defined an ADO.NET Entity Data Model, I can then instantiate it in a Repository class to query against the database. using (ApplicationEntities ctx = new ApplicationEntities()) { // query, CRUD, etc } However, that particular line of code becomes boilerplate in most of the methods in the repository class. Is it possible to just use Spring.NET to inject the Entity Data Model, either in the class or, even better, in an abstract parent class that all the repositories inherit from?

• Parameterized include in Classic ASP with VBScript

  - by Thom Smith

  I want to write a function that will include an external file, much like Server.Execute, but will pass along parameters. I'm aware that Server.Execute will pass along query parameters, but I'd like to pass data more generally. For instance: ' main.asp MyInclude("external.inc", Array("mykey", "myval")) ' external.inc Response.Write mykey I doubt I can get quite that far without reading the external fine, twiddling it, and executing, but I'd like to get as close as reasonably possible. Also, if possible, I'd prefer avoiding using the query passing option for security reasons.

• How to compute the probability of a multi-class prediction using libsvm?

  - by Cuga

  I'm using libsvm and the documentation leads me to believe that there's a way to output the believed probability of an output classification's accuracy. Is this so? And if so, can anyone provide a clear example of how to do it in code? Currently, I'm using the Java libraries in the following manner SvmModel model = Svm.svm_train(problem, parameters); SvmNode x[] = getAnArrayOfSvmNodesForProblem(); double predictedValue = Svm.svm_predict(model, x);

  Hey everyone, I am interested in doing some document clustering, and right now I am considering using TF-IDF for this. If I am not wrong, TFIDF is particularly used for evaluating the relevance of a document given a query. If I do not have a particular query, how can I apply tfidf to clustering?

• How do you search between two columns using a parameter and a case when statement? SQL Server

  - by Kip Birgen

  I would like to search between to columns in a s query or a table depending on the variable on a paramenter e.g Declare @SelectAll as interger Set @SelectAll = 1 Declare @Column as interger Select mt.Column1, mtColumn2 From MyTable as mt Where Case When @SelectAll = 1 Then mt.Column1 IN(@Column) and mt.Column2 (' Selecting all") When @SelectAll = 1 Then mt.Column2 IN(@Column) and mt.Column1 (' Selecting all") End The purpose of this query is to allow the user to search between the column they choose. Further more the use of parameter is for the purposes of writing reporting services reports.

• XML Return from an Oracle Stored Procedure

  - by Tequila Jinx

  Unfortunately most of my DB experience has been with MSSQL which tends to hold your hand a lot more than Oracle. What I'm trying to do is fairly trivial in tSQL, however, pl/sql is giving me a headache. I have the following procedure: CREATE OR REPLACE PROCEDURE USPX_GetUserbyID (USERID USERS.USERID%TYPE, USERRECORD OUT XMLTYPE) AS BEGIN SELECT XMLELEMENT("user" , XMLATTRIBUTES(u.USERID AS "userid", u.companyid as "companyid", u.usertype as "usertype", u.status as "status", u.personid as "personid") , XMLFOREST( p.FIRSTNAME AS "firstname" , p.LASTNAME AS "lastname" , p.EMAIL AS "email" , p.PHONE AS "phone" , p.PHONEEXTENSION AS "extension") , XMLELEMENT("roles", (SELECT XMLAGG(XMLELEMENT("role", r.ROLETYPE)) FROM USER_ROLES r WHERE r.USERID = USERID AND r.ISACTIVE = 1 ) ) , XMLELEMENT("watches", (SELECT XMLAGG( XMLELEMENT("watch", XMLATTRIBUTES(w.WATCHID AS "id", w.TICKETID AS "ticket") ) ) FROM USER_WATCHES w WHERE w.USERID = USERID AND w.ISACTIVE = 1 ) ) ) AS "RESULT" INTO USERRECORD FROM USERS u LEFT JOIN PEOPLE p ON p.PERSONID = u.PERSONID WHERE u.USERID = USERID; END USPX_GetUserbyID; When executed, it should return an XML document with the following structure: <user userid="" companyid="" usertype="" status="" personid=""> <firstname /> <lastname /> <email /> <phone /> <extension /> <roles> <role /> </roles> <watches> <watch id="" ticket="" /> </watches> </user> When I execute the query itself, replacing the USERID parameter with a string and removing the "into" clause, the query runs fine and returns the expected structure. However, when the procedure attempts to execute the query, passing the results of the XMLELEMENT function into the USERRECORD output parameter, I get the following exception: Error report: ORA-01422: exact fetch returns more than requested number of rows ORA-06512: at "USPX_GETUSERBYID", line 4 ORA-06512: at line 3 01422. 00000 - "exact fetch returns more than requested number of rows" *Cause: The number specified in exact fetch is less than the rows returned. *Action: Rewrite the query or change number of rows requested I'm baffled trying to nail this down, and unfortunately my google-fu hasn't helped. I've found plenty of Oracle SQL|XML examples, but none that deal with XML returns from a procedure. Note: I know that an alternate method of retrieving XML using DBMS methods exists, however, it's my understanding that that functionality is deprecated in favor of SQL|XML.

• Issues in Ada Concurrency

  - by Arkapravo

  Hi I need some help and also some insight. This is a program in Ada-2005 which has 3 tasks. The output is 'z'. If the 3 tasks do not happen in the order of their placement in the program then output can vary from z = 2, z = 1 to z = 0 ( That is easy to see in the program, mutual exclusion is attempted to make sure output is z = 2). WITH Ada.Text_IO; USE Ada.Text_IO; WITH Ada.Integer_Text_IO; USE Ada.Integer_Text_IO; WITH System; USE System; procedure xyz is x : Integer := 0; y : Integer := 0; z : Integer := 0; task task1 is pragma Priority(System.Default_Priority + 3); end task1; task task2 is pragma Priority(System.Default_Priority + 2); end task2; task task3 is pragma Priority(System.Default_Priority + 1); end task3; task body task1 is begin x := x + 1; end task1; task body task2 is begin y := x + y; end task2; task body task3 is begin z := x + y + z; end task3; begin Put(" z = "); Put(z); end xyz; I first tried this program (a) without pragmas, the result : In 100 tries, occurence of 2: 86, occurence of 1: 10, occurence of 0: 4. Then (b) with pragmas, the result : In 100 tries, occurence of 2: 84, occurence of 1 : 14, occurence of 0: 2. Which is unexpected as the 2 results are nearly identical. Which means pragmas or no pragmas the output has same behavior. Those who are Ada concurrency Gurus please shed some light on this topic. Alternative solutions with semaphores (if possible) is also invited. Further in my opinion for a critical process (that is what we do with Ada), with pragmas the result should be z = 2, 100% at all times, hence or otherwise this program should be termed as 85% critical !!!! (That should not be so with Ada)
