Select Command - Sql DataSource

May 21, 2016 10:59 AM|csajad|LINK

hi every body

Select Command :

SELECT stInfo.stId, stInfo.stName, stInfo.stName+'  '+stInfo.stFamily as nf, stInfo.stFamily, stInfo.stimage FROM Field INNER JOIN  Course ON Field.idField = Course.idField INNER JOIN  stInfo INNER JOIN  Class ON stInfo.stClass = Class.idClass ON Course.idField = stInfo.stField  where stClass='" + Session["gradlistkls"] + "' and Course.idCourse='" + Session["gradlistdrs"] + "'

SELECT stInfo.stId, stInfo.stName, stInfo.stName+'  '+stInfo.stFamily as nf, stInfo.stFamily, stInfo.stimage
 FROM Field INNER JOIN  Course ON Field.idField = Course.idField
 INNER JOIN  stInfo INNER JOIN  Class ON stInfo.stClass = Class.idClass ON Course.idField = stInfo.stField
  where stClass='" + Session["gradlistkls"] + "' and Course.idCourse='" + Session["gradlistdrs"] + "'

I used Session to Filter Select command.(Session["gradlistdrs"] and Session["gradlistkls"] )

How to write it in the Sql Data Source ?

                                        enter family  : 
                                        <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>

Since you are having concatenating operation inside the query, IMHO best option is to use StoredProcedure and then use SessionParameters in SQLDatasource

 <asp:SqlDataSource ConnectionString="<%$ ConnectionStrings:madrese %>"
            SelectCommand="Provide Your SP Name" SelectCommandType="StoredProcedure">
            <SelectParameters>
                <asp:SessionParameter Name="stClass" SessionField="gradlistkls"
                    DefaultValue="" />
                <asp:SessionParameter Name="Course" SessionField="gradlistdrs"
                    DefaultValue="" />
            </SelectParameters>
        </asp:SqlDataSource>

Sample SP

CREATE PROCEDURE YourStoredProcname 
	-- Add the parameters for the stored procedure here
	@stClass Varchar(100),
	@Course Varchar(100)
AS
BEGIN
    -- Select statements for procedure here
	SELECT stInfo.stId, stInfo.stName, stInfo.stName+'  '+stInfo.stFamily as nf, stInfo.stFamily, stInfo.stimage
     FROM Field INNER JOIN  Course ON Field.idField = Course.idField
     INNER JOIN  stInfo INNER JOIN  Class ON stInfo.stClass = Class.idClass ON Course.idField = stInfo.stField
      where stClass =@stClass and Course.idCourse=@Course
END
GO
