    <p>I'm working with the C# membership provider and transferring it to LINQ along the way.</p> <p>I'm having trouble pulling the results from a stored procedure in MS SQL. The procedure does some work to set variables and then selects the variables before setting the return value of 0.</p> <p>When I run this in MS SQL to test it works fine. When I run it with a regular command object and a reader in C# it works fine. However, when I'm using LINQ to run it I'm not able to get the results back, just the return value. </p> <p><strong>SQL Procedure</strong></p> <pre> ALTER PROCEDURE [dbo].[TEST] AS BEGIN **... DO WORK TO DECLARE AND SET VARIABLES ....** SELECT @Password, @PasswordFormat, @PasswordSalt, @FailedPasswordAttemptCount, FailedPasswordAnswerAttemptCount, @LastLoginDate, @LastActivityDate, @Status_Flag RETURN 0 END </pre> <p><strong>MSSQL Result Set</strong></p> <pre> host | 0 | NULL | 0 | 0 | 2009-09-22 00:57:22.700 | 2009-12-09 16:35:05.607 | 1 (1 row(s) affected) Return Value 0 (1 row(s) affected) </pre> <p><strong>LINQ</strong></p> <pre><code>var x = (from b in _linq.TEST() select b).Single(); </code></pre> <p><strong>LINQ Results</strong></p> <pre> NULL | NULL | NULL | NULL | NULL | NULL | NULL | NULL Return Value 0 </pre> <p>I've also verified that the sql seems to be the same being sent from LINQ as what I'm typing into MSSql.</p> <p><strong>Here's all of the LINQ that I've tried (and viewed in debugger to see results):</strong></p> <pre> // allow linq to create custom TESTResult type var result1 = _linq.TEST(); // get the return value from the type created above object p = result1.ReturnValue; // get the single result set from SP into the TESTResult type TESTResult result = _linq.TEST().Single(); // try to see one column to ensure null values aren't causing issues var y = (from b in _linq.TEST() select b.Column1).Single(); // try querying result set from LINQ var x = (from b in _linq.TEST() select b).Single(); </pre> <p>I've also tried playing with the database to change column values and remove nulls.</p>

    1. COLinq only has one result set, how are you printing the linq results?

    2. COI'm going in through the debugger to see what the results are from the Linq - 2 seperate places. If I just print the return value fort he stored proc (or look at it through the debugger) it is correct. If I print/look at the result set in LINQ it is NULL for each column.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
