DataSource Controls :: How To Get Rid Of The Temp Table

I am doing this in my stored proc. Creating a temp table. Dumping the select results into the temp table and then select the info where the search string is based on the status name info.

because of the temp table, it is taking long to excecute. How can I get rid of the temp table and still seach based on the CurrentStatusName

Create proc [dbo].[usp_GetRequestsInfoOnSearchString]
(
@SearchString varchar(100)
)
as
Create TABLE #Request(
[RequestId] [int] NULL,
[RequestDate] [datetime] NULL,
[RequestText] [varchar](500) NULL,
[CurrentStatusId] [int] NULL,
[RiskLevelId] [int] NULL
)
INSERT into #Request
([RequestId] ,
[RequestDate] ,
[RequestText] ,
[CurrentStatusId] ,
[RiskLevelId] )
SELECT [RequestId]
,[RequestDate]
,[RequestText]
,CurrentStatusName = dbo.udf_GetRequestStatusName(CurrentStatusId)
,[RiskLevelId]
FROM [dbo].[Request]
select [RequestId] as [Request Id]
,[RequestDate] as [Request Date]
,[RequestText] as [Request Text]
,[CurrentStatusName] as [Current Status Name]
from #Request
WHERE ([CurrentStatusName] like @SearchString OR len(@SearchString)= 0 OR @SearchString is null)
