Question

I am retrieving values from listbox and formatting them in string as

if (lbRaisedByLogin.SelectedIndex != -1)
    {
        foreach (ListItem item in lbRaisedByLogin.Items)
        {
            if (item.Selected == true)
            {
                sb.AppendFormat("{0},", item.Value);
            }
        }

        searchCase.raisedByLogin = sb.ToString().TrimEnd(Convert.ToChar(","));
        sb.Length = 0;
    }

I am passing these strings to store procedure as parameter (Datatype– Varchar(Max))

in stored procedure I am comparing these values like

SELECT * FROM AUS_CID_Cases
WHERE
AddedBy IN ( @raisedByLogin )

Where @raisedByLogin is one of the parameter i passed. It has values like @raisedByLogin=”4,2,1″

AddedBy has datatype bigint.

When I run code I get error as “Error converting data type varchar to bigint.”.. I understand it is because AddedBy column has datatype bigint. I can not change that datatype.

However when i cast AddedBy like

SELECT * FROM AUS_CID_Cases
WHERE
CAST(AddedBy as VARCHAR) IN ( @raisedByLogin )

I dont get error, but nothing is selected i.e I dont get any result from select statement.

What can I do?

First create this view

CREATE FUNCTION [dbo].[Split](@String varchar(8000), @Delimiter char(1))       
returns @temptable TABLE (items varchar(8000))       
as       
begin       
    declare @idx int       
    declare @slice varchar(8000)       

    select @idx = 1       
        if len(@String)<1 or @String is null  return       

    while @idx!= 0       
    begin       
        set @idx = charindex(@Delimiter,@String)       
        if @idx!=0       
            set @slice = left(@String,@idx - 1)       
        else       
            set @slice = @String       

        if(len(@slice)>0)  
            insert into @temptable(Items) values(@slice)       

        set @String = right(@String,len(@String) - @idx)       
        if len(@String) = 0 break       
    end   
return  

then change the query to this and try,

SELECT * FROM AUS_CID_Cases
WHERE
CAST(AddedBy as VARCHAR) IN ( select * from split(@raisedByLogin,',') )

found above Function here, and managed to solve this issue sometime back…
