Loop over SQL stored procedure - sql-server-2008

Question

I have a stored procedure In which insert query fire on two table.
masters_table,child_table as you see here #Value1,#Value2,#Value3,#Value4 having parameter. I have written insert statement for each block, can I make use loop here to avoid multiple insert write for each block, suppose I have nth value then i have to write nth time block wise insert query, any better way to achieve this task
Create proc sp_insert_master_child
(
#Details_Data custom_tb READONLY,
#Value1 nvarchar(500),
#Value2 nvarchar(500),
#Value3 nvarchar(500),
#Value4 nvarchar(500),
#Value5 nvarchar(500),
#Value6 nvarchar(500),
#Value7 nvarchar(500)
)
as begin
declare #id bigint
------- block 1
if #Value1 is not null
begin
insert into masters_table (col1,col2,col3))
select Substring(#Value1, 1,Charindex(',', #Value1)-1) as col_value_1,
Substring(#Value1, Charindex(',', #Value1)+1, LEN(#Value1)) as col_value_2
select #id = ##IDENTITY
insert into child_table (col1,col2,col3)
SELECT #id,col_val_2,col_val_3 FROM #Details_Data WHERE blockType='blk_1';
end
------ block 2
if #Value2 is not null
begin
insert into masters_table (col1,col2,col3))
select Substring(#Value2, 1,Charindex(',', #Value2)-1) as col_value_1,
Substring(#Value2, Charindex(',', #Value2)+1, LEN(#Value2)) as col_value_2
select #id = ##IDENTITY
insert into child_table (col1,col2,col3)
SELECT #id,col_val_2,col_val_3 FROM #Details_Data WHERE blockType='blk_2';
end
------ block 3
if #Value3 is not null
begin
insert into masters_table (col1,col2,col3))
select Substring(#Value3, 1,Charindex(',', #Value3)-1) as col_value_1,
Substring(#Value3, Charindex(',', #Value2)+1, LEN(#Value3)) as col_value_2
select #id = ##IDENTITY
insert into child_table (col1,col2,col3)
SELECT #id,col_val_2,col_val_3 FROM #Details_Data WHERE blockType='blk_3';
end
------ block 4
.......
------ block 5

You can insert all parameters into a table .Use while loop and read one by one row (parameter) from table .
Ex:
declare #x int
set #x= 1
declare #tmp table ( val int )
while (#x < noofrows)
begin
***********
Use Top #x value to get row(parameter in your case) from table
perform your operation
*************
increment x(set #X=#x+1)
end
