  • Cannot figure out how to take in generic parameters for an Enterprise Framework library sql statemen

    - by KallDrexx
    I have written a specialized class to wrap up the enterprise library database functionality for easier usage. The reasoning for using the Enterprise Library is because my applications commonly connect to both oracle and sql server database systems. My wrapper handles both creating connection strings on the fly, connecting, and executing queries allowing my main code to only have to write a few lines of code to do database stuff and deal with error handling. As an example my ExecuteNonQuery method has the following declaration: /// <summary> /// Executes a query that returns no results (e.g. insert or update statements) /// </summary> /// <param name="sqlQuery"></param> /// <param name="parameters">Hashtable containing all the parameters for the query</param> /// <returns>The total number of records modified, -1 if an error occurred </returns> public int ExecuteNonQuery(string sqlQuery, Hashtable parameters) { // Make sure we are connected to the database if (!IsConnected) { ErrorHandler("Attempted to run a query without being connected to a database.", ErrorSeverity.Critical); return -1; } // Form the command DbCommand dbCommand = _database.GetSqlStringCommand(sqlQuery); // Add all the paramters foreach (string key in parameters.Keys) { if (parameters[key] == null) _database.AddInParameter(dbCommand, key, DbType.Object, null); else _database.AddInParameter(dbCommand, key, DbType.Object, parameters[key].ToString()); } return _database.ExecuteNonQuery(dbCommand); } _database is defined as private Database _database;. Hashtable parameters are created via code similar to p.Add("@param", value);. the issue I am having is that it seems that with enterprise library database framework you must declare the dbType of each parameter. This isn't an issue when you are calling the database code directly when forming the paramters but doesn't work for creating a generic abstraction class such as I have. In order to try and get around that I thought I could just use DbType.Object and figure the DB will figure it out based on the columns the sql is working with. Unfortunately, this is not the case as I get the following error: Implicit conversion from data type sql_variant to varchar is not allowed. Use the CONVERT function to run this query Is there any way to use generic parameters in a wrapper class or am I just going to have to move all my DB code into my main classes?

  • jruby hangs on connection to sqlserver

    - by Christopher Dancy
    Jruby is hanging on connection to sqlserver and I cannot figure out why. Here is my code ... puts "make connection" ActiveRecord::Base.establish_connection( :adapter => 'jdbc', :driver => 'com.microsoft.jdbc.sqlserver.SQLServerDriver', :url => 'jdbc:sqlserver://test:1433;databaseName=test;integratedSecurity=true', :username=>'test', :password=>'test' ) puts "connected" fish = ActiveRecord::Base.connection.execute("SELECT * FROM users") puts "query ok" the code spits out "make connection" and then "connected" but never reaches "query ok" any ideas?

  • Is it possible to bind arrays of literals in sqlite3-ruby?

    - by willb
    I'd like to execute the following sort of query through sqlite3-ruby: SELECT * FROM foo WHERE bar IN (:items) and bind :items to one or many literals. Is this possible? The obvious technique of passing the list of literals as an array as follows doesn't seem to work: db.execute("SELECT * FROM foo WHERE bar IN (:items)", :items=>[3,1]) (In the above example, only the first value in the array is bound to :items.)

  • IP address numbers in MySQL subquery

    - by Iain Collins
    I have a problem with a subquery involving IPV4 addresses stored in MySQL (MySQL 5.0). The IP addresses are stored in two tables, both in network number format - e.g. the format output by MySQL's INET_ATON(). The first table ('events') contains lots of rows with IP addresses associated with them, the second table ('network_providers') contains a list of provider information for given netblocks. events table (~4,000,000 rows): event_id (int) event_name (varchar) ip_address (unsigned 4 byte int) network_providers table (~60,000 rows): ip_start (unsigned 4 byte int) ip_end (unsigned 4 byte int) provider_name (varchar) Simplified for the purposes of the problem I'm having, the goal is to create an export along the lines of: event_id,event_name,ip_address,provider_name If do a query along the lines of either of the following, I get the result I expect: SELECT provider_name FROM network_providers WHERE INET_ATON('192.168.0.1') >= network_providers.ip_start ORDER BY network_providers.ip_start DESC LIMIT 1 SELECT provider_name FROM network_providers WHERE 3232235521 >= network_providers.ip_start ORDER BY network_providers.ip_start DESC LIMIT 1 That is to say, it returns the correct provider_name for whatever IP I look up (of course I'm not really using 192.168.0.1 in my queries). However, when performing this same query as a subquery, in the following manner, it doesn't yield the result I would expect: SELECT event.id, event.event_name, (SELECT provider_name FROM network_providers WHERE event.ip_address >= network_providers.ip_start ORDER BY network_providers.ip_start DESC LIMIT 1) as provider FROM events Instead the a different (incorrect) value for network_provider is returned - over 90% (but curiously not all) values returned in the provider column contain the wrong provider information for that IP. Using event.ip_address in a subquery just to echo out the value confirms it contains the value I'd expect and that the subquery can parse it. Replacing event.ip_address with an actual network number also works, just using it dynamically in the subquery in this manner that doesn't work for me. I suspect the problem is there is something fundamental and important about subqueries in MySQL that I don't get. I've worked with IP addresses like this in MySQL quite a bit before, but haven't previously done lookups for them using a subquery. The question: I'd really appreciate an example of how I could get the output I want, and if someone here knows, some enlightenment as to why what I'm doing doesn't work so I can avoid making this mistake again. Notes: The actual real-world usage I'm trying to do is considerably more complicated (involving joining two or three tables). This is a simplified version, to avoid overly complicating the question. Additionally, I know I'm not using a between on ip_start & ip_end - that's intentional (the DB's can be out of date, and such cases the owner in the DB is almost always in the next specified range and 'best guess' is fine in this context) however I'm grateful for any suggestions for improvement that relate to the question. Efficiency is always nice, but in this case absolutely not essential - any help appreciated.

  • .Net Entity Framework SaveChanges is adding without add method

    - by tmfkmoney
    I'm new to the entity framework and I'm really confused about how savechanges works. There's probably a lot of code in my example which could be improved, but here's the problem I'm having. The user enters a bunch of picks. I make sure the user hasn't already entered those picks. Then I add the picks to the database. var db = new myModel() var predictionArray = ticker.Substring(1).Split(','); // Get rid of the initial comma. var user = Membership.GetUser(); var userId = Convert.ToInt32(user.ProviderUserKey); // Get the member with all his predictions for today. var memberQuery = (from member in db.Members where member.user_id == userId select new { member, predictions = from p in member.Predictions where p.start_date == null select p }).First(); // Load all the company ids. foreach (var prediction in memberQuery.predictions) { prediction.CompanyReference.Load(); } var picks = from prediction in predictionArray let data = prediction.Split(':') let companyTicker = data[0] where !(from i in memberQuery.predictions select i.Company.ticker).Contains(companyTicker) select new Prediction { Member = memberQuery.member, Company = db.Companies.Where(c => c.ticker == companyTicker).First(), is_up = data[1] == "up", // This turns up and down into true and false. }; // Save the records to the database. // HERE'S THE PART I DON'T UNDERSTAND. // This saves the records, even though I don't have db.AddToPredictions(pick) foreach (var pick in picks) { db.SaveChanges(); } // This does not save records when the db.SaveChanges outside of a loop of picks. db.SaveChanges(); foreach (var pick in picks) { } // This saves records, but it will insert all the picks exactly once no matter how many picks you have. //The fact you're skipping a pick makes no difference in what gets inserted. var counter = 1; foreach (var pick in picks) { if (counter == 2) { db.SaveChanges(); } counter++; } There's obviously something going on with the context I don't understand. I'm guessing I've somehow loaded my new picks as pending changes, but even if that's true I don't understand I have to loop over them to save changes. Can someone explain this to me?
