    <p>We have the ability to execute stored procs from the middle-tier. Basically, in a database table called "SQLJobStep" we have -- among other things -- a varchar(300) column called "StoredProcedure" which holds something like this:</p> <pre><code>usp_SendReminderEmails @Debug=0, @LoginID </code></pre> <p>Via the middle-tier, a user clicks on a link to run the proc of their choice. What happens in the backend is a proc ("usp_SQLJobsActionGet") looks up the correct value from the "SQLJobStep.StoredProcedure" column and executes the value above.</p> <p>This is the part of the code from "usp_SQLJobsActionGet" that executes the above value:</p> <pre><code>DECLARE @StepId int DECLARE @LoginID varchar(12) DECLARE @StoredProcedure varchar(300) SET @StepId = 74 SET @LoginID = 'Yoav' SELECT @StoredProcedure = SJS.StoredProcedure FROM SQLJobStep AS SJS WHERE SJS.StepId = @StepId SET @StoredProcedure = ISNULL(@StoredProcedure, '') IF CHARINDEX('@LoginID', @StoredProcedure) &gt; 0 BEGIN SET @LoginID = ISNULL(@LoginID, 'UNKNOWN') SET @StoredProcedure = REPLACE(@StoredProcedure, '@LoginID', '@LoginID = ''' + @LoginID + '''') END IF @StoredProcedure != '' BEGIN EXEC(@StoredProcedure) END </code></pre> <p>Fairly simple stuff....</p> <p>The above code converts the original value to (and then executes):</p> <pre><code>usp_SendReminderEmails @Debug=0, @LoginID = 'Yoav' </code></pre> <p>Here is the issue:</p> <p>When executing the "usp_SendReminderEmails @Debug=0, @LoginID = 'Yoav'" value nothing happens. No error is returned to the middle-tier. But I know that a value is pulled from the SQLJobStep table because we have other stored procedure values that get pulled and they run fine. (Note that the other values only have the @LoginID parameter, while this has @Debug=0 as well.)</p> <p>At the same time, if I run the code above (both the gutted code and calling "usp_SQLJobsActionGet" directly) in SQL Management Studio, it works perfectly.</p> <p>Do you have any advice? I am sure I am missing something very basic.</p> <p>Thanks.</p>

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.
