subsonic / SubSonic-3.0

To replicate this try the following

List excluded = new List();
var f = WebPageContent.Find(x => !usedID.Any(e => e == x.ID));

I know there is nothing in the list but in my scenario I have a list that might get populated so I need to do a Find then a Delete. I have tried doing just a Delete for less code and less DB hitss but there is a bug in the Delete lambda expression when doing a NOT IN type scenario. See Github issue 62.

At the moment I am having to do this:

if (usedID.Count > 0)
{ var f = WebPageContent.Find(x => !usedID.Any(e => e == x.ID));

        if (f.Count > 0)
        {
            var repo = WebPageContent.GetRepo();
            repo.Delete(f);
        }

}

I should just be able to do WebPageContent.Delete(x => !usedID.Any(e => e == x.ID));

3.0.0.3 SimpleRepository issue with MySQL Server 5.1 and .Net Connector 6.0.4

var p = repo.GetPaged(index, pagesize)

Throws a MySQL syntax exception when run. After doing some digging (getting the logs to work) this is the query that is being executed:

SELECT COUNT(``id``) AS `CountOfid` FROM Sales; //Does not work

SELECT COUNT(id) AS CountOfid FROM Sales; //Ran this to make sure it wasn't an issue in the DB and it runs like a champ.

I have this simple little method that is trying to use the SimpleRepositry Find method in SubSonic 3.0.0.3. When I make the call I get a invalid operation exception "Lambda Parameter not in scope".
To reproduce this fault I used the following code :

class SimpleCustomer

{
    /// <summary>
    /// Gets or sets the customer GUID.
    /// </summary>
    /// <value>The customer GUID.</value>
    public Guid CustomerGUID { get; set; }

    /// <summary>
    /// Gets or sets the ID tag number that is assigned to the customer
    /// </summary>
    /// <value>The ID.</value>
    public string ID { get; set; }

    public bool Active { get; set; }

    /// <summary>
    /// Gets or sets the first names.
    /// </summary>
    /// <value>The first names.</value>
    public string FirstNames { get; set; }
    /// <summary>
    /// Gets or sets the last names.
    /// </summary>
    /// <value>The last names.</value>
    public string LastNames { get; set; }
}

    public static void AddSimpleCustomer()
    {
        SimpleRepository repos = new SimpleRepository("EmptyDB", SimpleRepositoryOptions.RunMigrations);

        string searchTerm = "jon";
        string id = "00033221100";
        SimpleCustomer x = new SimpleCustomer();

        if (repos.Exists<SimpleCustomer>(c => c.ID == id) == false)
        {
            x.FirstNames = "John";
            x.LastNames = "Smith";
            x.ID = id;
            x.CustomerGUID = Guid.NewGuid();
            repos.Add<SimpleCustomer>(x);
        }
        // Boom - Thinks go horribly wrong here
        SimpleCustomer y = repos.Find<SimpleCustomer>(c => c.FirstNames.StartsWith(searchTerm)).FirstOrDefault();
        //Or Here
        y = repos.Find<SimpleCustomer>(c => c.FirstNames.Contains(searchTerm)).FirstOrDefault();

    }

I can work around this issue using

public override IEnumerable FindCustomers(string searchTerm)

    {            

        return Repos.All<Customer>().Where(cust => cust.FirstNames.Contains(searchTerm) || cust.LastNames.Contains(searchTerm)).ToArray();
    }

But given that it is using the All method, I suspect that this may not scale well :-)

ActiveRecord attempts to update computed columns in sql server. This effectively means that any table with a computed column can not be used.

These two commits add awareness of Computed columns, to the templates and the core.

• Computed columns can still be updated in code
• Core will not try to update/insert a column that is computed

In the future, it should make computed column property "protected set" , and not add them to the dirty columns collection.

Sorry about the CS files in there, don't know what to do bout that since I am so new to GIT.

There are some issues with the current trunk and invoking the datacontext.[Tables]. Count() or .Where(). I tried testing this today. My code is using trunk/master subsonic and active record templates from today (8/7/2009 @ 6PM CST)

Saving, getting, and deleting a single row worked fine in MediumTrust. When I tried to do a DB.Table.Where(o=> expression).ToList(); I got the SecurityException below. (this also happened when trying to pull all rows with a simple LINQ query. (from row in DB.Tables select row);

I don't have any suggestions yet. I believe this is happening on a Compile() function; possibly where the expression tree is constructed??? I haven't dug into it yet.

I am using activerecord (last subsonic source, with MySQL) and my table name is Payment. SubSonic generates a Payment class. Great! Almost everything works. One exception is SubSonic.Query.Insert, who calls the ToSchemaTable (there is a call to MakePlural there). As result, a obtain a wrong sql command, with Payments.

How a im doing:

SubSonic.Query.BatchQuery batch = new BatchQuery();

    var query = new SubSonic.Query.Insert(provider).Into<Payment>(new String[] { "Number", "Document", "ServiceNumber", "PaymentDate", "FreeDate" })
.Values(new Object[] { payment.Number, payment.Document,
payment.ServiceNumber, payment.PaymentDate.ToString("yyyy-MM-dd HH:mm:ss"),
payment.FreeDate.Value.ToString("yyyy-MM-dd HH:mm:ss") });
    batch.Queue(query);
    batch.Execute();

When I call Find() on a column that allows nulls, SubSonic is generating incorrect SQL. This happens only when I call Find() from a VB.NET project (SubSonic + templates are in a separate C# project in the same solution). If I call Find() from a C# project, there is no problem.

Details:

• latest SubSonic 3 (master branch, dated 2009-07-27) and ActiveRecord
• MS SQL Server 2005 Express Edition.
• Visual Studio 2008 solution
  • SubSonic and T4 templates in a C# class library project
  • My VB application in a separate project referencing the SubSonic project

Here's my table:

CREATE TABLE [dbo].[Fruit](
    [FruitID] [int] NOT NULL,
    [ColorID] [int] NULL,
 CONSTRAINT [PK_Fruit] PRIMARY KEY CLUSTERED 
 ...

In my VB code, I have

Dim bar = Fruit.Find(Function(f As Fruit) f.ColorID = 1)

SubSonic generates the following SQL

SELECT [t0].[ColorID], [t0].[FruitID]
FROM [dbo].[Fruit] AS t0
WHERE ([t0].[ColorID] = 1) <> 0

which fails to execute in DBDataProvider.ExecuteReader with

SqlException was unhandled by user code
Incorrect syntax near '<'

If I make the ColorID column "NOT NULL", the query generates correctly as:

SELECT [t0].[ColorID], [t0].[FruitID]
FROM [dbo].[Fruit] AS t0
WHERE ([t0].[ColorID] = 1)

If I execute the following equivalent Find() in C#, I also have no problems:

var foo = FooDB.Fruit.Find(x => x.ColorID == 1);

Please let me know if you need more information. If there are any workarounds that I can use until this makes it in, I'd appreciate it.

I have a column in SQL Server 2005 table of type varbinary(MAX). Generated active record class has the corresponding property type byte[]. I can successfully new-up the active record class representing the table, initialize values and save. The static method Find of the active record class returns the full set of data. When using the SubSonic.Linq.Structure.Query<T> then the byte[] field is always null.

In other words

var query = new Query<MyTable>();
var result = (from x in query select x).ToList();

if MyTable has a property of type byte[] (varbinary(MAX) in SQL Server 2005) then that property is always null in the result.

When querying using a GUID, the following error is returned:

The member 'xxx' is not supported. (xxx is the property name)

Example code:
Guid myId = new Guid("EE4FB3A9-2039-40FC-8241-F97967CF38A1");
IList test = Document.Find(x => x.xxx == myId);

I have various columns that aren't loading into my objects. None of the columns that are affected by naming changes resulting from my modified CleanUp method are being loaded. In this function, I'm just replacing underscores with string.empty and fixing the capitalization back like SubSonic 2.x, so "my_table" becomes "MyTable". The fields that weren't affected (other than capitalization changes) load fine.

Hello, I have a table called QuizItem that have these fields

id As Int
created As DateTime
header As Sring
body As String
fk_parent As int
url As String

All the items without parent key would be the question, and ones that have the parent key would be the answer. I am having the problem to get all the latest active questions (based both on questions created time and and answer created time).

I have used the following approach to do the query but keep getting the error or wrong result( answer and questions in diffrent group), is there some issue with the subsonic vb template, or my code is wrong, or sth else, any one can help me please.

From q In Quiz.Data.QuizItem.All Group q By masterID = If(q.FK_Parent Is Nothing, q.ID, q.ID) Into g = Group _

                           Order By g.Max(Function(q2) q2.Created) Descending Select New With {.masterItem = (From q3 In g Where q3.FK_Parent Is Nothing Select q3).Single}

Any idea is appreciated

public IQueryable Find(Expression<Func<T, bool>> expression)

in TestRepository returns all records, making unit tests which rely on the Active Record Testing using Find or SingleOrDefault fail.

What lead me down this road was the BOOL/TINYINT/SByte problem mentioned in issue #Num: #95 Figuring out the same as defacer.

After some digging around I find this: http://lists.mysql.com/commits/79014

And decide to try update MySQL.Data, I was using 5.2.5 iirc. I tried only 5.2.7 and 5.1.7 (and 5.2.5).
I got the same TINYINT -> SByte problem in all but 5.1.7. In the latter I now figure out that the ParameterMarker is ? and DbDataProvider.cs:104 ExecuteReader(QueryCommand qry) throws on /SubSonic.Core/DataProviders/DbDataProvider.cs#L130. saying "Column 'XYZ' cannot be null", even if parameters are added to the command. I found http://forums.mysql.com/read.php?38,200568,200573#msg-200573 and added "old syntax=true" in my connection string. Now instead I get a bunch of warnings for every query (I assume):

[23.08.2009 11:28:39] - WARNING:You are using old syntax that will be removed in future versions

coupled with

A first chance exception of type 'System.ArgumentException' occurred in System.Core.dll

stemming from SubSonic.Core/Linq/Structure/QueryMapping.cs#L159 in Output tool window.

I ask what have I done wrong? Do I not deserve SubSonic???

1. Delete the Products table from an Sqlite3 database.
   
2. Run the following code. This will add a Product to the Products table, creating the table in the process.
   

3. Result: The MyID field will have type nvarchar. Expected: MyID should have type nvarchar(10).

   namespace ss3simple {

   class Product
   {
       [SubSonicPrimaryKey]
       [SubSonicStringLength(10)]
       public string MyID { get; set; }
       [SubSonicStringLength(11)]
       public string Value { get; set; }
   
       public Product(string a, string b)
       {
           MyID = a;
           Value = b;
       }
   
       public Product() { }
   }
   
   class Program
   {
       static void Main(string[] args)
       {
           var repo = new SimpleRepository(SimpleRepositoryOptions.RunMigrations);
           repo.Add(new Product("hi", "there"));
       }
   }
   

   }

Using SQLite v3 and ActiveRecord pattern.Created a table named "User.Categories". When the T4 template is run, the "." in the name seems to cause a problem with namespaces and therefore class generation.

Hi using Subsonic 3.0.0.3 and MS SQL 2008 (10.0.2531) it appears there is some issue with Subsonic identifying Stored Procedure paramters as output parameters.

In the StoredProcedures.cs class I find my stored procedure definition but the last parameter is defined incorrectly as a 'AddParameter'.

sp.Command.AddParameter("HasPermission",HasPermission,DbType.Boolean);
When I sp.Execute() and attempt to read the value of the sp.Command.OutputValues[0] the value is null.

If the definition is edited to be like this;

sp.Command.AddOutputParameter("HasPermission", DbType.Boolean);
Then the value is returned and is correct value type

I am not sure how I 'fix' this - as everytime I regen the SP class via the 'Run Custom Tool' the parameter definitions require editing. Should I edit a T4 template somehow?

Please advise.

The GetTypeProjection method (line147) will throw an unhandled exception "Type 'System.Collections.Generic.IList`1[System.String]' does not have a default constructor" if i add some custom properties of type like IList{String},when the code runs at "return Expression.MemberInit(Expression.New(type), bindings);".

I think that the GetMappedMembers(type) method should exclude those custom fields and properties,because they don't belong to the ActiveRecord model,they are just custom added for certain biz intentions.

I attempted to make a primary key with UInt64, but no matter what I did it wouldn't run. however when I changed the datatype to long, it worked right on...

what are the datatypes allowed for the primary key?

I tried to find an attribute to disable autoinc key for the primary key, but couldn't find one.

is there a way to disable the auto increment so that I can set the id manually?

thanks!

SQL 2008 comes with the new datatype geography which is currently not supported. It should map to Microsoft.SqlServer.Types.SqlGeography or be converted to a byte array.

There is bug in ExecuteScalar method in DbDataProvider class. It always gives weird result if the result from cmd.ExecuteScalar() is null. The result is not null nor in some kind of value. I'm using MySQL template and MySQL Connector 6.1.

So I modified the returned value like this

return result != null & !string.IsNullOrEmpty(result.ToString()) ? result : null;

Hello,

At the moment types like decimals are being parsed using the current culture by the LINQ parser. This should be done using invariant culture, otherwise you would have to switch to invariant culture before every linq query.

The SQLite database that I use has a table (call it TEST) with a DateTime field (call it DT). Until recently, I have been inserting records into the table by doing the following:
TEST t = new TEST(); TEST.DT = DateTime.Now; TEST.Save();

In SQLite (using SQLiteStudio), this will appear something like this: 2009-09-28 16:29:26.4145701.

Recently, I switched to using a different approach, so that I could control the database connection:
Insert.Into(x => x.DT).Values(DateTime.Now).Execute();

This appeared to work - no errors on insert. SQLite showed the value differently, as 9/28/2008 1:23 PM. Unfortunately, this difference becomes apparent when the data gets read; when that happens, an exception about converting strings to datetime is thrown.

Expected behavior?

I originally asked a question about this on StackOverflow here: http://stackoverflow.com/questions/1467820/subsonic-getpaged-method-different-index-needed-in-unit-test

Adam thought that this was a bug/inconsistency with the GetPaged method using ActiveRecord, and suggested that I log it here.

I have a SQLServer and a MySQL database having a few columns containing spaces.

The project is correctly generated using T4 templates, the spaces from column names are removed by CleanUp and the project compiles.

However at runtime those columns containg spaces in their names are not read from the db, by using e.g. myTable.GetAll() or any other method.

The debugger will show a SELECT statement where these columns are not present, meaning there is a bug while generating this statment by Subsonic.Core.

When using the SimpleRepository 'Add' method and passing in an instance of 'T' where the primary key field is an integer (i.e public int PostID {...} in a class named 'Post') the return value is sent back typed as a decimal instead of an int. This appears to be related to how the data reader that reads back the 'SELECT SCOPE_IDENTITY' deals with that type.

I've seen this behavior on two different machines both of which were running against a local installation of SQL Server 2005 Express Edition.

in source code have a "#if debug console.writeline ..... " you can made something to enable write in a text file...

this will help a lot!!!

I am using SS 3.0.0.3 ActiveRecord (Current master build) with SQLite. This query:

new Update<BillDetail>(provider)
    .Set(bd => bd.DivisionDetails == divisionDetails)
    .Where(bd => bd.BillNumber == documentId && bd.IsInvoice == true);

produces this SQL:

UPDATE `BillDetails` 
    SET `DivisionDetails`=@up_DivisionDetails
    WHERE `BillNumber` = @0

Rob informed me here: http://stackoverflow.com/questions/1368405/subsonic-3-updatet-problem that the problem was fixed but it still is not.

I am using SS 3.0.0.3 ActiveRecord (Current master build) with SQLite (I think this error might be reproducable in other databases also, although I didn't checked).

If I do something like this:

var customerRepo = Customer.GetRepo();
var customerList = customerRepo.GetAll().ToList();

And then after making changes to the list, try to do this:

customerRepo.Update(customerList);

It causes a SQLite error because if the customer is not changed (i.e. IsDirty flag is false) the sql is not empty but this:

UPDATE `Customers`
    WHERE `Id` = @0;
UPDATE `Customers`
    WHERE `Id` = @1;

If a check for IsDirty flag is added to method public int Update(IEnumerable items, IDataProvider provider) at line 279 of SubSonic.Core\Repository\SubSonicRepository.cs, the error is resolved.

The resultant public int Update(IEnumerable items, IDataProvider provider) method should be:

    public int Update(IEnumerable<T> items, IDataProvider provider)
    {
        BatchQuery bQuery = new BatchQuery(provider);
        int result = 0;

        foreach(T item in items)
        {
            if (((IActiveRecord)item).IsDirty()) // adding this check fixes the problem...
            {
                var query = item.ToUpdateQuery(provider);
                bQuery.Queue(query);
            }
        }
        result = bQuery.Execute();
        return result;
    }

I am having a problem while using the test repository and it makes it IMPOSSIBLE to test...

This line of code:

     var dbFriend = Friend.SingleOrDefault(f => f.UserId == id && f.FriendId == friendId);

Always returns the first element regardless of whether the expression is matched or not. This happens because of

    var results=repo.Find(expression);

in the ActiveRecord.cs file.

I tried to step through it but couldn't figure it out.

My table looks like this:

FriendUserId - unique, bigint, auto increment
FriendId - big int
UserId - big in

I also noticed that the autoincrement features doesn't work in test mode. Is that correct behavior?

The update method in the test repository doesn't work. This method:

    public int Update(T item)
    {
        var update = _items.SingleOrDefault(x => x.KeyValue() == item.KeyValue());
        _items.Remove(item);
        _items.Add(update);
        return 0;
    }

always sets the variable "update" to null because x.KeyValue() == item.KeyValue() always fail because it is trying to compare two references instead of their values. Even though I have an item with the primary key = 3 it will still return null because it is boxing 3 and comparing two objects instead of two integers (I think!!!)

If I change the method to

    public int Update(T item)
    {
        var update = _items.SingleOrDefault(x => x.KeyValue().ToString() == item.KeyValue().ToString());
        _items.Remove(item);
        _items.Add(update);
        return 0;
    }

then the "update" variable is correctly retrieved but the PROBLEM now is

    _items.Remove(item)

does NOT remove the item from the collection... Not sure why???

I need some help. It is impossible to use the TestRepository in its current state...

I just started to use subsonic and I have an issue. I only checked it briefly.

When updating an active record object the schema name is missing. If you update the same object or delete it, the schema name is present in the SqlQuery which gets passed to the ANSISqlGenerator.cs. If the table is not under the dbo schema I, of course, get an exception.

In generated Structs.cs file, the schema name is present for the table.
