  • connecting to secure database on private network from website host

    - by jim
    Hello all, I've got a requirement to both read and write data via a .net webservice to a sqlserver database that's on a private network. this database is currently accessed via a vpn connection by remote client software (on standard desktop machines) to get latest product prices and to upload product stock sales. I've been tasked with finding a way to centralise this access from a webservice that the clients then access, rather than them using the vpn route to connect directly to the database. My question is related to my .net service's relationship to the sqlserver database. What are the options for connecting to a private network vpn from a domain host in order to achive the functionality of allowing the webservice to both read and write data to the database. For now, I'm not too concerned about the client connectivity and security (tho i appreciate that this will have to be worked out too), I'm really just interested in discovering the options available in order to allow my .net webservice to connect to the private network in as painless and transparent a way as posible. [edit] the webservice will also be available to the retail website in order for it to lookup product info as well as allocate stock transfers to the same sqlserver db. it will therefore be located on the same domain as the retail site The option of switching the database onto public hosting is not feasible, so I have to work with the scenario as described above for now, unless there's a compelling rationale presented to do otherwise. thanks all... jim

  • Storing images in a Microsoft SQL Server 2005 database

    - by Rekreativc
    Hello! I have a question about storing an image in a database. I know this topic has been discussed before, however I feel that in my case this is actually a good idea - the images will be small (none should be as large as 1MB) and there shouldn't be too many. I like the idea of not worrying about IO permissions etc. Anyway I have a problem when storing the image (byte[]) to the database type image. Here is my code: OleDbCommand comm = new OleDbCommand(strSql, Program.GetConnection()); comm.Parameters.Add("?", SqlDbType.Image).Value = bytearr; comm.ExecuteNonQuery(); Everything compiles fine, however when I run it, the code only saves the value 63 (0x3F) into the field - no matter which image I am trying to save. What could be the problem? Thank you for your help.

  • How to 'insert if not exists' in MySQL?

    - by warren
    I started by googling, and found this article which talks about mutex tables. I have a table with ~14 million records. If I want to add more data in the same format, is there a way to ensure the record I want to insert does not already exist without using a pair of queries (ie, one query to check and one to insert is the result set is empty)? Does a unique constraint on a field guarantee the insert will fail if it's already there? It seems that with merely a constraint, when I issue the insert via php, the script croaks.

  • How to find all records that share the same field value as some other record?

    - by Gj
    I need to extract all records which have a field which does NOT have a unique value. I can't figure out an elegant way to do it - using annotation or some other way. I see a "value_annotate" method to the object manager but it's unclear if it's at all related. Currently I'm using the inelegant way of simple looping through all values and doing a get on the value, and if there's an exception it means it's not unique.. Thanks

  • ASP.Net delete record audit trigger

    - by Germ
    Suppose you have the following... A ASP.NET web application that calls a stored procedure to delete a record. The table has a trigger on it that will insert an audit entry each time a record is deleted. I want to be able to record in the audit entry the person who deleted the record. What would be the best way to go about achieving this? I know I could remove the trigger and have the delete stored procedure insert the audit entry prior to deleting but are there other recommeded alternative?

  • association of more than one model to a listview

    - by Veer
    I have 3 Tables in my database. Each table has 3 fields each, excluding the ID field. out of which 2 fields are of type nvarchar. None of the tables are related. My ListView in the application helps the user to search my database, the search being incremental. The search includes the nvarchar fields of the 3 tables ie, 6 fields in total. Eg: PhoneBook: Name, PhoneNo Notes: Title, Content Bookmarks: Name, url I've the models generated for the 3 tables. Now the ListBox should display the Ph.Name, Title and the Bo.Name fields. ie, It should be bound to them. But they are from different models. I also should be able to perform CRUD operation on the item searched. How would i do that? P.S: Separate ViewModels are created for each Model which are used for their respective views for handling those tables individually. But this is an integrated view where the user should be able to search everything. Also please somebody suggest me a better Title for this question:)

  • Sanitizing DB inputs with XSLT

    - by azathoth
    Hello I've been looking for a method to strip my XML content of apostrophes (') like: <name> Jim O'Connor</name> since my DBMS is complaining of receiving those. By looking at the example described here, that is supposed to replace ' with '', I constructed the following script: <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output omit-xml-declaration="yes" indent="yes" /> <xsl:template match="node()|@*"> <xsl:copy> <xsl:apply-templates select="node()|@*" /> </xsl:copy> </xsl:template> <xsl:template name="sqlApostrophe"> <xsl:param name="string" /> <xsl:variable name="apostrophe">'</xsl:variable> <xsl:choose> <xsl:when test="contains($string,$apostrophe)"> <xsl:value-of select="concat(substring-before($string,$apostrophe), $apostrophe,$apostrophe)" disable-output-escaping="yes" /> <xsl:call-template name="sqlApostrophe"> <xsl:with-param name="string" select="substring-after($string,$apostrophe)" /> </xsl:call-template> </xsl:when> <xsl:otherwise> <xsl:value-of select="$string" disable-output-escaping="yes" /> </xsl:otherwise> </xsl:choose> </xsl:template> <xsl:template match="node()|@*"> <xsl:apply-templates name="sqlApostrophe"/> </xsl:template> </xsl:stylesheet> However, the processor isn't accepting it. What am I missing here? Is there a better way to get rid of the apostrophes? Perhaps another approach for sanitizing DB inputs by using XSLT? Thanks for your help

  • Creating a Doctrine query with a different number of ids

    - by frapet
    Is it possible to create a Doctrine query with a differnt number of ids coming from a submitted form? And if yes how? What I am trying to do is this: .... if ($input->isValid()) { $q = Doctrine_Query::create() ->from('Imm_Model_Images i') ->whereIn('i.ImageID = ?', array($input->ids)); $result = $q->fetchArray(); PS: ids come form the submitted form in an array as ids[]. Added Edit: chaged the above line: ->whereIn('i.ImageID = ?', array($input->ids)); with: ->whereIn('i.ImageID = array($input->ids)'); ...and it seems to work.

  • Disable animations when ending search in iPhone

    - by camilo
    Hi. A quicky: is there a way to dismiss the keyboard and the searchDisplayController without animation? I was able to do it when the user presses "Cancel", but when the user presses the black "window thingy" above search field (only visible while the user hasn't inserted any text), the animation always occurs, even when I change the delegate functions. Is there a way to control this, or as an alternative, to disable the user to end searching by pressing the black window? Thanks in advance.

  • Database abstraction/adapters for ruby

    - by Stiivi
    What are the database abstractions/adapters you are using in Ruby? I am mainly interested in data oriented features, not in those with object mapping (like active record or data mapper). I am currently using Sequel. Are there any other options? I am mostly interested in: simple, clean and non-ambiguous API data selection (obviously), filtering and aggregation raw value selection without field mapping: SELECT col1, col2, col3 = [val1, val2, val3] not hash of { :col1 = val1 ...} API takes into account table schemas 'some_schema.some_table' in a consistent (and working) way; also reflection for this (get schema from table) database reflection: get list of table columns, their database storage types and perhaps adaptor's abstracted types table creation, deletion be able to work with other tables (insert, update) in a loop enumerating selection from another table without requiring to fetch all records from table being enumerated Purpose is to manipulate data with unknown structure at the time of writing code, which is the opposite to object mapping where structure or most of the structure is usually well known. I do not need the object mapping overhead. What are the options, including back-ends for object-mapping libraries?

  • How do I choose a database?

    - by liamzebedee
    I need a comparison table of some sort for database varieties (MySQL, SQLite etc.). I can't find one. My use case is, I am implementing storage of objects in a distributed hash table. I need a database solution that is: Fast for sorting Simplistic (no users, preferably no additional structures like multiple tables etc.) Concurrent (if possible) Multi-platform File based (not stored in memory primarily) Centralized I will be programming in Go. As I understand, I believe I need what is called a Document Orientated Database, because I am storing objects, identified by keys. EDIT: While I am implementing a DHT, I will also be storing metadata about the objects, such as access counts etc. It would also be preferable to have TLL (time to live)

  • Using stored procedures to generate RDLC report in C#

    - by NDraskovic
    I'm making an application that generates reports for my client. I'm using his database that contains stored procedures which return the data needed for the reports. The problem is that I don't know how to execute them from the application (more specific the TableAdapter in my dataset). When I use the visual aid to create the TableAdapter, it shows the error "Invalid object named #table1". This is weird because there is a temporary table called #table1 in the stored procedure. When I try to do the whole job programmatically, I get the exception Incorrect syntax near '.'. An object or column name is missing or empty. For SELECT INTO statements, verify each column has a name. For other statements, look for empty alias names. Aliases defined as "" or [] are not allowed. Change the alias to a valid name. I created a DataTable that has identical structure as the result of the stored procedure, but I still get the same exception

  • How to count how many items for distinct items in mysql?

    Imagine a have a table with a column named status: status ------ A A A B C C D D D How can I count how many rows have A, how many rows have B etc? this kind of output: A |B |C |D |E ------------------ 3 |1 |2 |3 |0 As for E = O , this will always be A,B,C,D and E Output should be one row (thus 1 query). When doing a distinct count (most returning answer on my searches, it does return how many different elements there are, 4 in this case...)
