    <p>I believe that the issue is a result of you passing a column <code>EmpDetails.EmpCode</code> name to the table-valued function, instead of a single value. You could try this instead:</p> <pre><code>DECLARE @EmpCode nvarchar(100); SELECT TOP 1 @EmpCode = EmpCode FROM Employee.tblEmp_Demographics WHERE RecordStatus='present'; select *,ROW_NUMBER() OVER (PARTITION BY EmpCode ORDER BY DateTaken DESC) AS RowNum, (select GradeName From Master.GradeMaster where GradeCode=Grade And Deleted=0) As Grade, SUM(Amount) OVER(PARTITION BY Grade) AS EmpAmount, SUM(DependentAmount) OVER(PARTITION BY Grade) As DepAmount, 0 As CheckNo from [dbo].[SELECT_AIRTICKET_DETAILS_BY_DATE](@EmpCode,getdate(),1) WHERE YEAR(DateTaken)=year(getdate()); </code></pre> <p>If you want results for multiple values from the <code>Employee.tblEmp_Demographics</code> table, you could iterate through each value (probably not best), or modify your table-valued function to return a result set with all EmpCode values, and then add a <code>WHERE</code> clause to filter the data as needed.</p> <hr> <p><em><strong>Edit</em></strong></p> <p>Something like this perhaps - note the modified function that returns all EmpCodes &amp; has one less parameter:</p> <pre><code>select *,ROW_NUMBER() OVER (PARTITION BY EmpCode ORDER BY DateTaken DESC) AS RowNum, (select GradeName From Master.GradeMaster where GradeCode=Grade And Deleted=0) As Grade, SUM(Amount) OVER(PARTITION BY Grade) AS EmpAmount, SUM(DependentAmount) OVER(PARTITION BY Grade) As DepAmount, 0 As CheckNo FROM [dbo].[SELECT_AIRTICKET_DETAILS_BY_DATE](getdate(),1) AS [Tickets] INNER JOIN Employee.tblEmp_Demographics ON tblEmp_Demographics.EmpCode = [Tickets].EmpCode AND tblEmp_Demographics.RecordStatus = 'present' WHERE YEAR(DateTaken) = year(getdate()); </code></pre> <p>With this solution, the function returns all EmpCodes, but we filter out the unnecessary ones by performing an <code>INNER JOIN</code> on the <code>Employee.tblEmp_Demographics</code> table.</p>

    2. COThe first `SELECT` statement gets the value from the `Employee.tblEmp_Demographics` table & saves it in the `@EmpCode` variable that is subsequently passed to the `[SELECT_AIRTICKET_DETAILS_BY_DATE]` function in the first parameter.

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.
