  • double authentication issue on IIS / Report Server (SQL server 2008)

    - by Vinzz
    Hi, On a 2003 server box, with SQL server 2008 installed (ReportServer deployed in IIS mode), I've got a virtual directory within IIS with it's security set to 'windows authentication', with the following html code: <body> <h1>test</h1> <iframe src="/reportserver" witdh="50%" height="50%" /> </body> From the outside, I've got a first login/pwd box displayed to access the html code, then a second one to display the content of the iframe. On the same type of server, but with SQL Server 2005, I don't have this issue (i.e. only one login box). My thought is that the first token should give acces to both the page and the iframe, isn't it? Any hints on how to setup the reportserver to fix this? thanks.

  • Valid Email Addresses - XSS and SQL Injection

    - by PAAMAYIM_NEKUDOTAYIM
    Since there are so many valid characters for email addresses, are there any valid email addresses that can in themselves be XSS attacks or SQL injections? I couldn't find any information on this on the web. The local-part of the e-mail address may use any of these ASCII characters: Uppercase and lowercase English letters (a–z, A–Z) Digits 0 to 9 Characters ! # $ % & ' * + - / = ? ^ _ ` { | } ~ Character . (dot, period, full stop) provided that it is not the last character, and provided also that it does not appear two or more times consecutively (e.g. [email protected]). http://en.wikipedia.org/wiki/E-mail_address#RFC_specification I'm not asking how to prevent these attacks (I'm already using parametrized queries and HTML purifier), this is more a proof-of-concept. The first thing that came to mind was 'OR [email protected], except that spaces are not allowed. Do all SQL injections require spaces?

  • Access sql server without directly permission in domain from ASP.NET

    - by Yongwei Xing
    Hi all Here is the situation. All the machines and users are in the same domain.We are in a domain enviroment. There are some sql server 2005/2008 storing data. There is a ASP.NET site in the domain using the Window Authentication. Now, we need read the data from the sql server and display them using SqlDataSource and GridView. But most of users do not have the direct permission to access the database. Is there any solution to get the data from database and display them on the site without granting users permission? Best Regards,

  • SQL Server uncorrelated subquery very slow

    - by brianberns
    I have a simple, uncorrelated subquery that performs very poorly on SQL Server. I'm not very experienced at reading execution plans, but it looks like the inner query is being executed once for every row in the outer query, even though the results are the same each time. What can I do to tell SQL Server to execute the inner query only once? The query looks like this: select * from Record record0_ where record0_.RecordTypeFK='c2a0ffa5-d23b-11db-9ea3-000e7f30d6a2' and ( record0_.EntityFK in ( select record1_.EntityFK from Record record1_ join RecordTextValue textvalues2_ on record1_.PK=textvalues2_.RecordFK and textvalues2_.FieldFK = '0d323c22-0ec2-11e0-a148-0018f3dde540' and (textvalues2_.Value like 'O%' escape '~') ) )

  • SQL Script to clear database tables.

    - by pencilslate
    I have a need to take backup of a SQL Server Db with tons of data in it and import into another environment for updating and testing. Since, i am not interested in the data, i just want to recreate the schema on my other server. There is an option called 'Generate Script', but is throwing errors running them on the target server. Curious, if anyone attempted to write a SQL script that would run through all the tables in the db and clear the rows, thereby i could just create the schema backup as .bak file and restore it into another server.

  • Check if a SQL table exists.

    - by Carra
    What's the best way to check if a table exists in a Sql database in a database independant way? I came up with: bool exists; const string sqlStatement = @"SELECT COUNT(*) FROM my_table"; try { using (OdbcCommand cmd = new OdbcCommand(sqlStatement, myOdbcConnection)) { cmd.ExecuteScalar(); exists = true; } } catch (Exception ex) { exists = false; } Is there a better way to do this? This method will not work when the connection to the database fails. I've found ways for Sybase, SQL server, Oracle but nothing that works for all databases.

  • SQL Cartesian product joining table to itself and inserting into existing table

    - by Emma
    I am working in phpMyadmin using SQL. I want to take the primary key (EntryID) from TableA and create a cartesian product (if I am using the term correctly) in TableB (empty table already created) for all entries which share the same value for FieldB in TableA, except where TableA.EntryID equals TableA.EntryID So, for example, if the values in TableA were: TableA.EntryID TableA.FieldB 1 23 2 23 3 23 4 25 5 25 6 25 The result in TableB would be: Primary key EntryID1 EntryID2 FieldD (Default or manually entered) 1 1 2 Default value 2 1 3 Default value 3 2 1 Default value 4 2 3 Default value 5 3 1 Default value 6 3 2 Default value 7 4 5 Default value 8 4 6 Default value 9 5 4 Default value 10 5 6 Default value 11 6 4 Default value 12 6 5 Default value I am used to working in Access and this is the first query I have attempted in SQL. I started trying to work out the query and got this far. I know it's not right yet, as I’m still trying to get used to the syntax and pieced this together from various articles I found online. In particular, I wasn’t sure where the INSERT INTO text went (to create what would be an Append Query in Access). SELECT EntryID FROM TableA.EntryID TableA.EntryID WHERE TableA.FieldB=TableA.FieldB TableA.EntryID<>TableA.EntryID INSERT INTO TableB.EntryID1 TableB.EntryID2 After I've got that query right, I need to do a TRIGGER query (I think), so if an entry changes it's value in TableA.FieldB (changing it’s membership of that grouping to another grouping), the cartesian product will be re-run on THAT entry, unless TableB.FieldD = valueA or valueB (manually entered values). I have been using the Designer Tab. Does there have to be a relationship link between TableA and TableB. If so, would it be two links from the EntryID Primary Key in TableA, one to each EntryID in TableB? I assume this would not work because they are numbered EntryID1 and EntryID2 and the name needs to be the same to set up a relationship? If you can offer any suggestions, I would be very grateful. Research: http://www.fluffycat.com/SQL/Cartesian-Joins/ Cartesian Join example two Q: You said you can have a Cartesian join by joining a table to itself. Show that! Select * From Film_Table T1, Film_Table T2;

  • Paging Recordsets from SQL Serverside

    - by Jonno
    I've been banging my head off this one for a while. I want to call 1k records from a SQL database and page them per 100. In classic ASP (where I'm moving from) this was dead easy to do with ADODB but with VB using ADO.net I can't find a single way that doesn't involve stored procs (which I want to avoid for now). It seems really stupid to call all 1k and sort it programmatically. Edit: It's SQL Server 2005 / .net 4.0 / Visual Studio 2010. Edit 2: Just to reiterate, I have Googled extensively and don't want to use stored procedures. There are many ways to get paged data but everything I see involves paging the data in the program rather than from the server.

  • Exclude records matching subquery

    - by Skudd
    There is probably an obvious answer to this question, but I am having one heck of a time getting anywhere with it. Consider the query: SELECT * FROM reports AS r JOIN reportvalues AS rv ON rv.report_id = r.report_id JOIN metrics AS m ON m.metric_id = rv.metric_id WHERE r.report_id NOT IN( SELECT DISTINCT report_id FROM exclude_report ) In this query, exclude_report is a view constructed in a similar manner. Now what happens is the query takes an EXTREMELY long time to execute, presumably because the subquery is being executed over each and every row in the parent query. However, I am finding no feasible means of doing this any other way. Oh great SQL wizards, please advise. I really need a way of doing this all in SQL, which I will be using in SSRS.

  • MS SQL Server 2000 tables

    - by klork
    We currently have an MS SQL Server 2000 database with one table containing data for multiple users. The data is keyed by memberid which is an integer field. The table has a clustered index on memberid. The table is now about 200 million rows. Indexing and maintenance are becoming issues. We are debating splitting the table into one table per user model. This would imply that we would end up with a very large number of tables potentially upto the 2,147,483,647, considering just positive values. My questions: 1) Does anyone have any experience with a MS SQL Server (2000/2005) installation with millions of tables? 2) What are the implications of this architecture with regards to maintenance and access using Query Analyzer, Enterprise Manager etc. 3) What are the implications to having such a large number of indexes in a database instance. All comments are appreciated. Thanks

  • Finding group maxes in SQL join result

    - by Gene
    Two SQL tables. One contestant has many entries: Contestants Entries Id Name Id Contestant_Id Score -- ---- -- ------------- ----- 1 Fred 1 3 100 2 Mary 2 3 22 3 Irving 3 1 888 4 Grizelda 4 4 123 5 1 19 6 3 50 Low score wins. Need to retrieve current best scores of all contestants ordered by score: Best Entries Report Name Entry_Id Score ---- -------- ----- Fred 5 19 Irving 2 22 Grizelda 4 123 I can certainly get this done with many queries. My question is whether there's a way to get the result with one, efficient SQL query. I can almost see how to do it with GROUP BY, but not quite. In case it's relevant, the environment is Rails ActiveRecord and PostgreSQL.

  • Microsoft Access vs Native SQL

    - by ktm5124
    Hypothetical: Let's say you are writing complex queries to a database and it is very important that the data you extracted is the correct result set (e.g., that you didn't mess up a JOIN by not using all the correct keys, and all the other things that can go wrong, et cetera). What would you rather use to do this? Would you write the query using Microsoft Access and its Design View, or would you write it in native SQL using a SQL IDE? What is the better professional choice? Thanks in advance your feedback!

  • Access DB with SQL Server Back End

    - by uyuni99
    I have an old Access application that has a lot of code in forms and reports. The database is getting too large and I am thinking of moving the back end to SQL Server. My requirements are as follows: The DB needs to be multiuser and the users (3-5) will need to log in over the web I would prefer not to re-write the forms and reports in ASP or some other web front end. When I think about my choices, I see them as: Have an Access ADP front end and allows remote log-in to the server where it is stored. Not sure if it is possible for 2 users to simultaneously log in Distribute an ADP front end to the users, but I am not sure if it is possible to connect to a SQL Server back end over the internet, and the network traffic may be an issue. Any other solution? I appreciate all help. u

  • Hibernate HQL to basic SQL

    - by CC
    Hello everybody, I working on a project with Hibernate and we need to replace Hibernate with some "home made persistence" stuff. The idea is that the project is big enough, and we have many HQL queries. The problem is with the queries like select a,b from table1, table2 on t1.table1=t2.table2 Basically all joins are not supported by our "hand made persistence" stuff. What I would need, is to be able to do some sort of transcoder, which will take as a input the HQL queries and output some SQL, but the basic SQL without joins, something like (a dumb example) select a from table1 where t1 IN ( select b from table2) I hope you get the idea. My persistence layer does not supports joins. Does anybody has any idea about something like that? Some framework, or something? Thanks alot everybody. C.C.

  • VBA SQL Loop using QODBC

    - by Dan
    I am trying to loop through an existing table (tblSalesOrder) and I need to run through every line (where they relate to that particular customer) and write each line into an SQL statement and execute it. What is the easiest way to go about this procedure? The number of lines will need to be counted prior to data being written via SQL to a QuickBooks database. I can code something similar in php using the code below, but I am unsure how to convert this into a VBA friendly format: $sql_count = "SELECT count(*) FROM tblSalesOrder WHERE Customer='cust_number'"; execute_query($sql_count) When the above value is greater than 0, the vba code should loop through the queries. Thanks everyone

  • SSIS - SharePoint to SQL without Adapter Addin?

    - by Mark
    Hey all, Im looking to Extract a SharePoint List (WSS 2.0) to a SQL(2005) Table using SQL Server Integrated Services. First off I am aware of the "adapter" that does this from http://msdn.microsoft.com/en-us/library/dd365137.aspx however I'm just wondering for compatibility purposes if it can't just be done "out of the box". There are only a limited number of "Data Flow Sources" to select as alternatives and I am unsure if any of these would be able to work in a similar way either directly to SharePoint or via SharePoints web services (e.g. http://server_name/_vti_bin/Lists.asmx) From the list of these sources it looks like the best option would be the OLE DB connector, but not sure how it would do this. Any help you have would be great, Mark

  • Adding tables to sql server result in Domain\user.name.tablename

    - by Ryan Howe
    Our app uses migratordotnet to modify the backing SQL Server 2005 database. This works great 99% of the time but we are running into an issue. We have a client that is using and Active Directory group for sql server login and when new tables are added it creates them as Domain\login.table_name. What permissions are needed to be given to the AD group to add the tables as dbo.table_name? This does not happen in with all of our clients with similar configurations so I must be missing something.

  • Linq To SQL: Retain list order when using .Contains

    - by rockinthesixstring
    I'm using Lucene.net to build a MyListOfIds As List(Of Integer) which I then pass on to my Linq service. I then search the database as follows Return _EventRepository.Read().Where(Function(e) MyListOfIds.Contains(e.ID)).ToList Now I know that Lucene is already ordering MyListOfIds based on the weight it gave each term. What sucks is that Linq is losing that order in it's SQL search. My Question: How can I retain that sort order when building my Lambda expression? I tried using LINQPad to see how the query is being built, but because I had to declare a variable LINQPad didn't show me the resultant SQL :-( Here's what I tried in LINQPad Dim i As New List(Of Integer) i.Add(1) i.Add(100) i.Add(15) i.Add(3) i.Add(123) Dim r = (From e In Events Where i.Contains(e.ID) Select e) note: my example is in VB.NET, but I don't mind if responses are in C#

  • Understanding CGI and SQL security from the ground up

    - by Steve
    This question is for learning purposes. Suppose I am writing a simple SQL admin console using CGI and Python. At http://something.com/admin, this admin console should allow me to modify a SQL database (i.e., create and modify tables, and create and modify records) using an ordinary form. In the least secure case, anybody can access http://something.com/admin and modify the database. You can password protect http://something.com/admin. But once you start using the admin console, information is still transmitted in plain text. So then you use HTTPS to secure the transmitted data. Questions: To describe to a learner, how would you incrementally add security to the least secure environment in order to make it most secure? How would you modify/augment my three (possibly erroneous) steps above? What basic tools in Python make your steps possible? Optional: Now that I understand the process, how do sophisticated libraries and frameworks inherently achieve this level of security?

  • A better understanding of the relations beetween database tables

    - by Nistor Alexandru
    Hi I am trying to get a better understanding of relational databases and there is something that I keep bumping into and don't understand.Let's take this two tables: In this case Login.ID is the primary key with auto_increment set and Profile.ID_LOGIN is the Foreign KEY.When a user is created and it's username and password is stored in the login database does the ID coresponding to the curesnt username and password get automaticly added into ID_LOGIN or do I have to create an SQL statement to do this? If I have to create a SQL statement how should I aproach adding the ID_LOGIN to make sure I am adding it corectly?

  • SQL Server Mapping a user to a login and adding roles programmatically

    - by user163457
    In my SQL Server 2005 server I create databases and logins using Management Studio. My application requires that I give a newly created user read and write permissions to another database. To do this I right-click the newly created login, select properties and go to User Mapping. I put a check beside the database to map this login to the db and select db_datareader and db_datawriter as the roles to map. Can this be done programmatically? I've read about using Alter User and sp_change_users_login but I'm having problems getting these to work, since sp_change_users_login has been deprecated so I'd prefer to use Alter User. Please note my understanding of SQL Server database users/logins/roles is basic
