How To Pass Coulmn Values To A Stored Procedure

Hi,
I need to automate the procedure of selecting column with numeric and passing those column values as string to another stored procedure.

Here is sample code :
CREATE procedure procdeure1 @Utility varchar(50) WITH RECOMPILE
as
if @Utility='Electricity'
begin
IF EXISTS (SELECT * FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_NAME = 'gmmers1')
DROP TABLE gmmers1
IF EXISTS (SELECT * FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_NAME = 'gmmers2')
DROP TABLE gmmers2
create table gmmers1(sitecode varchar(15),
Gen_Electricity_Usage bigint
)
create table gmmers2 (gmmerssitecode varchar(15),
Gmers_Electricity_Usage bigint
)
insert into gmmers1
Select site.Sitecode,sum(isnull(AcctRptdata.ElectricityUse,0)*factor) as 'Electricity Usage'
From GEN..AcctRptdata AcctRptdata, GEN..site site,SuperAccesslevels.dbo.convfactor,SuperAccesslevels.dbo.countrysettings
Where ((AcctRptdata.Year*100)+AcctRptdata.Month) >= 200511 and
--((AcctRptdata.Year*100)+AcctRptdata.Month) < year(DATEADD(m,-1, GetDate()))*100+month(DATEADD(m,-1, GetDate())) and
((AcctRptdata.Year*100)+AcctRptdata.Month) >= 200511 and ((AcctRptdata.Year*100)+AcctRptdata.Month) <= 200707 and
site.idsite = AcctRptdata.siteid and site.sitecode not like ('C%')
and len(sitecode ) = 8
and AcctRptdata.idsvc in (100) and
SuperAccesslevels.dbo.convfactor.[Default] = SuperAccesslevels.dbo.countrysettings.IdUnitElec and
SuperAccesslevels.dbo.countrysettings.IdCountrySetting = Site.IdCustomerSetting and [user] = 1
and site.Sitecode not like '%B%'
and site.sitecode not like '9999%'
and AcctRptdata.ElectricityUse >0 --Added on 16th Aug
and site.sitecode in (select left (sitecode,8) from GEN..site where len(sitecode) >8)--= 11)
--and site.sitecode in (select left(sitecode,8) from gmers_prodn..facility_data where len(sitecode) = 11)
Group by site.Sitecode having sum(AcctRptdata.ElectricityUse*factor) > 0 Order by site.Sitecode

insert into gmmers2
select left (sitecode, 8) BU, sum(isnull(KWh_Purchased_Quantity, 0 )) as 'electric use' from gmers_prodn..electricity_data
where sitecode in --(select sitecode from facility_data where left (sitecode ,8) in
(select sitecode from gen..site where sitecode not like 'C%' and len(sitecode ) > 8 )
-- and len (sitecode) = 11)
and rpt_dt >= '2005-11-01' and rpt_dt < '2007-08-01'
--and sitecode like 'A0916323%'
and sitecode not like '%B%' and left(sitecode,8) not in ('N0010024','N0010088','N0010101','N0010173',
'N0010373','N0010447') and sitecode not like '9999%'
group by left (sitecode, 8) order by left (sitecode, 8) -- yyyy-mm-dd


select *,(Gen_Electricity_Usage-Gmers_Electricity_Usage)as Diff from gmmers1,gmmers2
where gmmers1.sitecode=gmmers2.gmmerssitecode and (Gen_Electricity_Usage-Gmers_Electricity_Usage) <>0
end
else if @UTILITY='GAS'
begin
IF EXISTS (SELECT * FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_NAME = 'gengas')
DROP TABLE gengas
IF EXISTS (SELECT * FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_NAME = 'gmmersgas')
DROP TABLE gmmersgas
create table gengas(sitecode varchar(15),
Gen_Gas_usage bigint
)
create table gmmersgas (gmmerssitecode varchar(15),
Gmers_Gas_Usage bigint
)
insert into gengas
Select site.Sitecode,sum(isnull(AcctRptdata.NaturalGasUse,0)*factor) as 'Gas Usage' From GEN..AcctRptdata AcctRptdata,
GEN..site site,SuperAccesslevels.dbo.convfactor,SuperAccesslevels.dbo.countrysettings
Where ((AcctRptdata.Year*100)+AcctRptdata.Month) >= 200511 and
--((AcctRptdata.Year*100)+AcctRptdata.Month) < year(DATEADD(m,-1, GetDate()))*100+month(DATEADD(m,-1, GetDate())) and
((AcctRptdata.Year*100)+AcctRptdata.Month) >= 200511 and ((AcctRptdata.Year*100)+AcctRptdata.Month) <= 200707 and
site.idsite = AcctRptdata.siteid and site.sitecode not like ('C%')and
len(sitecode ) = 8 and AcctRptdata.idsvc in (200,300) and
SuperAccesslevels.dbo.convfactor.[Default] = SuperAccesslevels.dbo.countrysettings.IdUnitGas and
SuperAccesslevels.dbo.countrysettings.IdCountrySetting = Site.IdCustomerSetting and [user] = 61
and site.sitecode not like '%B%' and site.sitecode not like '9999%'
and site.sitecode in (select left (sitecode,8) from GEN..site where len(sitecode) >8)
and AcctRptdata.NaturalGasUse >0 ----Added on 16th Aug
--and site.sitecode in (select left(sitecode,8) from gmers_prodn..facility_data where len(sitecode) = 11)
Group by site.Sitecode having sum(AcctRptdata.NaturalGasUse*factor) > 0 Order by site.Sitecode

insert into gmmersgas
select left( sitecode, 8 ) BU , sum(Utility_Natural_Gas_Volume) as 'gas use' from GMERS_PRODN..fuel_data
where sitecode in --(select sitecode from facility_data where left (sitecode,8) in
(select sitecode from gen..site where sitecode not like 'C%' and len(sitecode ) > 8 )
-- and len(sitecode )= 11 )
and rpt_dt >= '2005-11-01' and rpt_dt < '2007-08-01'
and sitecode not like '%B%' and sitecode not like '9999%'
group by left( sitecode, 8 ) order by left( sitecode, 8 )

select *,(Gen_Gas_usage-Gmers_Gas_Usage)as Diff from gengas,gmmersgas
where gengas.sitecode=gmmersgas.gmmerssitecode and (Gen_Gas_usage-Gmers_Gas_Usage)<>0
end

My aim is to pass sitecode having difference <>0 and from date and todate as an parameter to another stored procedure which updates sitewise for the utility so that in case a particular sitecode with same date range is included in one utility it should not be repeated in another utility.
