Web Forms :: Creating Own Query Analyzer?

Jan 7, 2010

Is it possible to create my own query analyzer?The idea is the user just have to type their query in a textbox (SELECT only) then after pressing the execute button, records will be displayed in the page.If the user uses Insert, Delete or anything transactional, it will display msg that will prohibit the user executing the script

Building A Generic Page "Query Analyzer" Like In Asp.net With SMO?

Mar 26, 2010

I'm build a web page in ASP.net is supposed to work just like Query Analyzer. It has basically a textarea to input the sql command, and an Execute button.I'm using SMO to execute the command in the database, as follows:

//Create object SMO
Microsoft.SqlServer.Management.Smo.Server server = new Microsoft.SqlServer.Management.Smo.Server(new Microsoft.SqlServer.Management.Common.ServerConnection(oConn));

//To execute the command
server.ConnectionContext.ExecuteNonQuery(tbx_cmd.Text);
//OR
myDataset = server.ConnectionContext.ExecuteWithResults(tbx_cmd.Text);

The problem is that the textarea command can contain anything, from a stored procedure (with GO's statements) and any select command that return resultsets, just like Query Analyzer.But, if I have GO statements, I only can perform the query using ExecuteNonQuery method. If I use the ExecuteWithResults method, it raises errors because of the GO statements.And if I want the resultsets to be available, of course I can only use the ExecuteWithResults method. how can I do to execute the same command texts at the same time?

JQuery :: Creating JSON Object From AD Query

Mar 23, 2011

I'm new to Jquery, JSON and MVC, and am trying to create a json object that contains AD info from an AD query. The ad query is working fine and returning data and I have 2 overloaded implementations of it.

#1 is a method from an older .net app that builds and returns a datatable that we bound to a grid view control

#2 was a modification of #1 that returns a System.Collections.Generic.List<> type. #2 returns data ok and i can display a table in the MVC view

however, I'd like to get the data results into a json object so i can bind it to a jqGrid object that has similar functionality to the old .Net server controls (Delete, Update, Sort) Here's the new method that's part of a C# static class:

[Code]....

Like I said...I'm new to this way of doing web development, so I'm not sure how to even approach getting this data into a json object.

Forms Data Controls :: Query Working In Query Builder But Not In Webpage?

Jul 13, 2010

I'm encountering a strange problem. Here is the scenario. I have built a query that accepts a parameter (WHERE LIKE clause).

I've tested this within the query builder and it returns exactly the number I would expect.

I then go back to my webpage and add the following controls:

Dropdown

Gridview

the user to make a selection from the dropdown. Postback on the dropdown is enabled so the page reloads and the Gridview displays the filtered results (via an objectdatasource). I've set the parameter to the dropdown control.

The trouble is when I run the page I make the selection in the dropdown no results are displayed. Even though the text displayed in the dropdown control is exactly the same as I inputted into the query builder when testing it.

DataSource Controls :: SqlDataSource And Parameters Query / Trying To Accomplish Is Building Dynamic Query

Aug 22, 2010

1. I have a GridView on my page and it uses sqldatasource with parameterized query. What I want to do is, on page load (where nothing has been selected so no parameter supplied), I want it to query everything (something like SELECT * FROM [this_table]) but since my SelectCommand is something like

SELECT * FROM [this_table] WHERE [this_column] = @someParameters AND [that_column] = @someParameters.

Can I play around with default value to achieve something like that but how ? Now, when the page loads, it doesn't show anything (No Gridview).

2. On my page, I made something like (username, gender, address, and more) and one single search button. That means, no single control enable auto postback. What I am trying to accomplish is building dynamic query

(if username specifed -> SELECT * FROM [this_table] WHERE [username] LIKE @username).

If both username and gender are specified (SELECT * FROM [this_table] WHERE [username] LIKE @username AND [gender] = @gender) and you know the rest. How can I do this using GridView and SqlDataSource ? To my knowledge, I can only specify one SELECT statement in a sqldatasource.

C# - Sql Inline Query - Parameter Is Not Read When The Query Is Executed

Apr 23, 2010

I am having a problem with my sql query in c#, basically it's inline query with parameters, but when I run it it tells me that parameter 1 or parameter 2 is not there here is my query declared on top of the page as public:

public const string InsertStmtUsersTable = "insert into Users (username, password, email, userTypeID, memberID, CM7Register) " +
"Values(@username, @password, @email, @userTypeID, @memberID,@CM7Register ); select @@identity";

this is my code for assigning the parameters, I know I am having problem so I am assigning the params twice:

Username =(cmd.Parameters["@username"].Value = row["username"].ToString()) as string;
cmd.Parameters["@username"].Value = row["username"].ToString();

In 1 methopd it calls this query and tries to insert to table, here is the code:

Result = Convert.ToInt32(SqlHelper.ExecuteScalar(con, CommandType.Text,InsertStmtUsersTable));

Exact error message is: Must declare the variable '@username'. Could this code be a problem, because all the previous coding is declared with in this using statement, except declaration of query, here the using statement: using (SqlCommand cmd = new SqlCommand(InsertStmtUsersTable, con))

DataSource Controls :: Accessing FK From A Query Via Entity Query

Jan 21, 2010

I've got a query such as

Dim MediaQuery =
From m
In dB.DOWNLOADS _Where m.ID = id _Select

which returns a record from the database. One of the fields in the record is a FK to another table. I need to read this value to be able to set a dropdown based on the ID but I can't work out how to access it. For a standard record I can just do the following txtTitle.Text = MediaQuery.FirstOrDefault().TITLE

However with the foreign key it doesn't work like that. I've tried drpGroup.SelectedIndex = MediaQuery.FirstOrDefault().DOWNLOAD_GROUPS.ID where DOWNLOAD_GROUPS is the FK field but it returns Object reference not set to an instance of an object. If you're simply wanting to read some values from a single db record in the entitiy framework and one is a foreign key how should I go about getting the value?

Linq Query Returning Less Records Than Sql Query?

Mar 19, 2011

I am facing a big problem with simple linq query.. I am using EF 4.0..

I am trying to take all the records from a table using a linq query:

var result = context.tablename.select(x=>x);

This results in less rows than the normal sql query which is select * from tablename;

This table has more than 5 tables as child objects (foreign key relations: one to one and one to many etc)..

This result variable after executing that linq statement returns records with all child object values without doing a include statement.. I don't know is it a default behavior of EF 4.0 . I tried this statement in linqpad also..but there is no use... But interesting thing is if I do a join on the same table with another one table is working same is sql inner join and count is same..but I don't know why is it acting differently with that table only.. Is it doing inner joins with all child tables before returning the all records of that parent table?

Linq Query - How To Select Inner Query Into List

I am writing a linq query to select a blogpost,

[code]....

The blogpost i am testing got 3 tags attached to it. The table structure is:

(table)BlogPost -> (table)BlogPostTags <- (table)Tags

So the BlogPostTags table only contains 2 fields, BlogPostID and TagID.

When i run the query above i get 3 results back. Same blogpost 3 times but with 1 tag in each. It should return 1 post with 3 tags. The problem lies in the Tags query above.
