  • DAL without web2py

    - by Jay
    I am using web2py to power my web site. I decided to use the web2py DAL for a long running program that runs behind the site. This program does not seem to update its data or the database (sometimes). from gluon.sql import * from gluon.sql import SQLDB from locdb import * # contains # db = SQLDB("mysql://user/pw@localhost/mydb", pool_size=10) # db.define_table('orders', Field('status', 'integer'), Field('item', 'string'), # migrate='orders.table') orderid = 20 # there is row with id == 20 in table orders #when I do db(db.orders.id==orderid).update(status=6703) db.commit() It does not update the database, and a select on orders with this id, shows the correct data. In some circumstances a "db.rollback()" after a commit seems to help. Very strange to say the least. Have you seen this, more importantly do you know the solution? Jay

  • 'ORA-01031: insufficient privileges' error received when inserting into a View

    - by Patrick K
    Under the user name 'MY_ADMIN', I have successfully created a table called 'NOTIFICATIONS' and a view called 'V_NOTIFICATIONS'. On the 'V_NOTIFICATIONS' view I have successfully created a trigger and a package that takes what the user attempts to insert into the view and inserts it into the table. The 'V_NOTIFICATIONS' trigger and package also perform the update and delete functions on the table when the user attempts to perform the update and delete functions on the view. I have done this with many views in the project I am currently working on, as many views sit over the top of many different tables, however when attempting to insert a record into this view I receive an 'ORA-01031: insufficient privileges' error. I am able to insert directly into the table using the same code that is in the package, but not into the view. Any help on this would be greatly appreciated.

  • Spring Security DB Authentication w/Hibernate and hashed passwords?

    - by Seth
    I'm trying to set up spring security 3 to authenticate users against my hibernate 3 database. I'm storing only sha1 hashes of the passwords in the database (not plaintext). I've looked at this and this, which tell me to implement my own UserDetailsService. Unfortunately, the UserDetails that loadUserByUsername spits out seem to need the plaintext password, which I don't have. How is this usually handled? Can Spring Security actually do what I need here? Am I missing something?

  • Convert xml as string

    - by hakish
    i have a scenario where in i need to send an xml as a tag content in a SOAP request message to a webservice for example <arg_1><xml version="1.0" encoding="UTF-8"?><sometag><somemoretag>abcd</somemoretag></sometag></arg_1></code> arg_1 happens to be an String parameter to a webservice. So i bring in a CDATA section for this <arg_1><![CDATA[<xml version="1.0" encoding="UTF-8"?><sometag><somemoretag>abcd</somemoretag></sometag>]]></arg_1> But this keeps throwing me an exception org.xml.sax.SAXException: WSWS3084E: Error: SimpleDeserializer encountered a child element, which is NOT expected, in something it was trying to deserialize. Message being parsed: I keep getting this exception. Has anyone seen this before??

  • ADD COLUMN to sqlite db IF NOT EXISTS - flex/air sqlite?

    - by Adam
    I've got a flex/air app I've been working on, it uses a local sqlite database that is created on the initial application start. I've added some features to the application and in the process I had to add a new field to one of the database tables. My questions is how to I go about getting the application to create one new field that is located in a table that already exists? this is a the line that creates the table stmt.text = "CREATE TABLE IF NOT EXISTS tbl_status ("+"status_id INTEGER PRIMARY KEY AUTOINCREMENT,"+" status_status TEXT)"; And now I'd like to add a status_default field. thanks! Thanks - MPelletier I've add the code you provided and it does add the field, but now the next time I restart my app I get an error - 'status_default' already exists'. So how can I go about adding some sort of a IF NOT EXISTS statement to the line you provided?

  • Fetch and bulk collect from a REF CURSOR returned by a procedure

    - by Rachcha
    I have a procedure that has a SYS_REFCURSOR as an OUT parameter. The signature is, for example, as follows: PROCEDURE myProc(p_someID IN INTEGER, p_cursor OUT SYS_REFCURSOR); I call this procedure from a function, where I have to copy a column named clientID from the p_cursor to a scalar nested table. I am doing as follows: CREATE OR REPLACE FUNCTION myFunction RETURN sys_refcursor IS someID INTEGER := 1234; myCursor SYS_REFCURSOR; TYPE t_clientID_nt IS TABLE OF NUMBER(16,0); clientID_nt t_clientID_nt; otherID SYS_REFCURSOR; BEGIN myProc (someID, myCursor); FOR i IN myCursor LOOP clientID_nt.EXTEND; clientID_nt (clientID_nt.COUNT) := i.clientID; END LOOP; -- Other code that opens the cursor otherID -- based on the IDs in clientID_nt ... ... RETURN otherID; END; / When I try to compile this function, the error I get is: PLS-00221: 'CLIENTID_NT' is not a procedure or is undefined and it is at line 11 of the code. Any help on how to fetch and bulk collect from such a cursor is greatly appreciated.

  • DBMS debugger causes TOAD to hang

    - by James Collins
    I can start the dbms debugger in Toad and use it normally but if I hit the 'halt execution' button or just hit the 'Run' button to reach the end of the function it causes TOAD to hang. Windows reports it as not responding and I have to kill it through the task manager. I have had this problem in Toad 9.7.2.5 and Toad 10 on two different laptops. Has anyone else experienced this problem? If you have did you find a solution to this?

  • wm_concat function and small characer buffer

    - by Ruslan
    Hi, i have select like: select substr(account,1,4), currency, amount, module,count(*) quan, wm_concat(id) ids from all_transactions group by substr(account,1,4), currency, amount, module But sometimes COUNT(*) is more then 600. In that case i get: 'ORA-06502: PL/SQL: : character string buffer too small' Is there any way out to keep wm_concat(id) for all records? Because excluding this function for entries with big COUNT(*) is the way out.

  • PHP with DB backed-end application to complete windows EXE possible or not?

    Hi, Let's say I have a php application backed-end with SQLite and I would like to convert whole application to exe file so the end user can just click it and run on windows. User should be able to save, update and add new data into database without any web server or browser things. Is it possible? I found out that we can use PHP-GTK for UI. exeoutput.com supports with database engines according to it's website. Anyone have tried it out? If I'm missing something, pls share with me. Thanks all in advance and happy new year!!!

  • Tutorials for .NET database app using SQLite

    - by ChrisC
    I have some MS Access experience, and had a class on console c++ apps, now I am trying to develop my first program. It's a little C# db app. I have the db tables and columns planned and keyed into VS, but that's where I'm stuck. I'm needing C#/VS tutorials that will guide me on configuring relationships, datatyping, etc, on the db so I can get it ready for testing of the schema. The only tutorials I've been able to find either talk about general db basics (ie, not helping me with VS/C#), or about C# communications with an existing SQL db. Thank you. (In case it matters, I'm using the open source System.Data.SQLite (sqlite.phxsoftware.com) for the db. I chose it over SQL Server CE after seeing a comparison between the two. Also I wanted a server-less version of SQL because this little app will be on other people's computers and I want to to do as little support as possible.)

  • Spring Security - is Role and ACL security overkill?

    - by HDave
    I have a 3 tier application that requires security authorizations be placed on various domain objects. Whether I use Spring's ACL implementation or roll my own, it seems to me that ACL based security can only be used to authorize (service) methods and cannot be used to authorize URL or web service invocations. I think this because how could a web service call check the ACL before it has hydrated the XML payload? Also, all the examples for web access security in the Spring documentation are securing URL's based on Role. Is it typical to use Spring's roles to secure web presentation and web service calls, while at the same time using ACL's to secure the business methods? Is this overkill?

  • Global Temporary Table Concurrency

    - by sahs
    Hi, I have a global temp table which is set as delete on commit. How does it behave on concurrency issue? I mean what happens if another session wants to use that global temporary table? The answer will probably not be "they share the same data". Now, if my guess is correct :), is the table locked until the first connection commits, or does the dbms create a global temp table for each connection? ( something like an instance of the table? )

  • optimizing operating systems to provide maximum informix performance.

    - by Frank Developer
    Are there any Informix-specific guides for optimizing any operating system where an ifx engine is running? For example, in Linux, strip-down to a bare minimum all unecessary binaries, daemons, utilities, tune kernel parameters, optimize raw and cooked devices (hdparm). Someday, maybe, informix can create its own proprietary PICK-like O/S. The general idea is for the OS where ifx sits on have the smallest footprint, lowest overhead impact on ifx and provide optimized ifx performance.

  • One check constraint or multiple check constraints?

    - by RenderIn
    Any suggestions on whether fewer check constraints are better, or more? How should they be grouped if at all? Suppose I have 3 columns which are VARCHAR2(1 BYTE), each of which is a 'T'/'F' flag. I want to add a check constraint to each column specifying that only characters IN ('T', 'F') are allowed. Should I have 3 separate check constraints, one for each column: COL_1 IN ('T', 'F') COL_2 IN ('T', 'F') COL_3 IN ('T', 'F') Or a single check constraint: COL_1 IN ('T', 'F') AND COL_2 IN ('T', 'F') AND COL_3 IN ('T', 'F') My thoughts are it is best to keep these three separate, as the columns are logically unrelated to each other. The only case I would have a check constraint that examines more than one column is if there was some relationship between the value in one and the value in another, e.g.: (PARENT_CNT > 0 AND PRIMARY_PARENT IS NOT NULL) OR (PARENT_CNT = 0 AND PRIMARY_PARENT IS NULL)
