How To Make Table Name Dynamic
Feb 22, 2011
I am trying to create an autocomplete textbox using jquery which will be bound to SQL database. I also want to place a dropdownlist on the page so based on initial selection autocomplete textbox will retrieve data from different tables. It's an ASP.NET 2.0 page and code behind is VB.NET. I have AJAX autocomplete working but it matches only first characters and its not as robust as jquery. Can anyone share a sample code that will retrieve search data from SQL and also give me directions on how to make the table name dynamic?

I have an MS access database with some .dbf files linked to it. One of the dbf file is a sales file. I am trying to generate a report for each of the month's sales. For that the sales dbf file will be different for each of the month. I want to give an option to the user to specify the file name from which he wants to use to generate the report. After accepting the input from the user, i need to link to that table in MSACCESS. Is there a way to achieve this from vb.net

I'm developing an application to allow engineers to conduct simple single table/view queries against our databases by selecting Database, Table, Fields.
I get how to use the Dynamic LINQ Library Sample to provide for dynamically selecting the Select, Where and Order by Clauses at runtime but I'm at an impass on how to allot for table choice.
Is there a way to provide for dynamically selecting the "from" table at run time
EDIT
So Both of the answers seem to be saying the same general Idea. I'm going to try to convert the C# into VB and get it to work.
The first answer converts to
NotInheritable Class DataContextExtensions
Private Sub New()
End Sub

Is there a way to use Meta Tales or Table names to Construct a dynamic query in LINQ?
foreach (var metaTable in db.Mapping.GetTables())
{
var queryType = metaTable.RowType.Type;
[code]....
Is there a way to do something like this? The attempt above yields the error:Could not find an implementation of the query pattern for source type 'System.Data.Linq.ITable'. 'Select' not found. Consider explicitly specifying the type of the range variable 'q'.

I'm trying to query old Access database tables and compare them with SQL Server tables.They often don't have primary keys, or they have extra fields that had some purpose in the nineties, etc., or the new tables have new fields, etc.I need to find records - based on a set of fields specified at runtime - that are in one table but not another.So, I do this kind of query all the time in SQL, when I'm comparing data in different tables:
dim fields_i_care_about as string = "field1, field2, field3"
'This kind of thing gets set by a caller, can be any number of fields, depends on the
'table
dim s as string= ""
[code]....
It tells me it can't convert a Boolean - Is there any way to do this without Linq expressions? They seem far more complex than what I'm trying to do here, and they take a lot of code, and also I can't seem to find examples of Expressions where we're comparing two fields in a subquery.Is there a simpler way? I know I could do the usual EXISTS query using JOIN or IN - in this case I don't need the query to be super fast or anything. And I don't need to use a DataTable or DataSet - I can put the data in some other kind of object.

I've a DLL assembly reading a variable, "GalleryID", from an XML file. I can't modify the assembly, so I am wondering if I can make the XML element value dynamic? For example, to get this value from a querystring or any other scenario without changing the assembly.[code]This is an ASP.NET website that has multiple users. When a user logs in and open the gallery.aspx page it will show the user's own gallery. This scenario is not working now since the gallery module shows one gallery (Galleryid=2) to all users according to its setting in Settings.xml file. How can I pass galleryid in querystring -- gallery.aspx?galleryid=5 and inject it to Settings.xml file?

I have developed a vb.net app with MS access as back end db.when i installed exe on client's machine, it gives error that it couldn't find the db file on client's machine, even though i have changed the connection string in app.config file after the installation. What i have found out is that when a dataset is created at development time and whatever the address is at that time , that is the address it looks for at client's machine.

I have the following linq query:
Dim q = From definition In definitionList _
Where definition.ValueDefName.Contains(criteria)[code]....
I have already looked into this answer: LINQ - dynamic WHERE clause?Unfortunately, it doesn't work for me using .net 4.0. When I attempt to pass the criteria string in it ask for a predicate. The end goal is to add any of these:
definition.ValueDefname.Contains(criteria)
definition.ValueDefDesc.Contains(criteria)
definition.Aliaslist.Contains(Criteria)
definition.StrategicInitiative.Contains(Criteria)
to be passed into the query depending on what checkboxes the user has selected. How can I create a dynamic where clause in linq to sql? Is there new syntax for passing in a where clause as a string?

I am trying to automate an access table make query through vb.net.It works fine the first time, but the second time it fails because the table already exists.Of course i can delete the table through code by it's name, but i want to let my .net-application find out wich table must be deleted. Or maybe there is a solution that doesn't fail with the error "table exists" without first deleting it.[code]

How would I change this code to make the factory dynamic. I believe I was close with remoting. I don't want any hardcoding of the factory, nor do I want to have to recompile. The database drives it.

factoryObject = _dal.GetFactoryObject(ruleId)

Ho can you make a dynamic label stay right justified, so that when the label.text is filled the text starts at the right edge of the label and fills to the left? Currently the text fills to the right from the left edge of the labels location and tends to run off the form.

I need to represent the following query using LINQ:

Now, I know that a query in .NET doesnt look like this, this is my test in the SQL Design Studio. Naturally VB.NET variables will be used in place of the SQL local variables.My problem is this: All of the conditions after "WHERE" are optional. In that a query might be made that uses one, some, all, or none of the conditions. V.PropertyID and V.Value can also appear any number of times.In VB.NET I can make this query easy enough by simply concatenating strings, and using a loop to append the "V.PropertyID/V.Value" conditions.I can also make a Stored Procedure in MS SQL, which is easy enough.However, I want to accomplish this using LINQ.
