Issue with splitting values and passing to a stored procedure - sql-server

Question

Iam getting the below input parameter values in one of the stored procedure.
#DocKey1, #DocValue1,
#DocKey2, #DocValue2,
#DocKey3, #DocValue3,
#DocKey4, #DocValue4,
#DocKey5, #DocValue5
From this procedure iam calling another procedure to insert each pair of values.
Right now am calling the InsertDocValues stored procedure multiple times to insert each pair.
exec InsertDocValues #DocKey1, #DocValue1
exec InsertDocValues #DocKey2, #DocValue2
exec InsertDocValues #DocKey3, #DocValue3
exec InsertDocValues #DocKey4, #DocValue4
exec InsertDocValues #DocKey5, #DocValue5
Is there anyway i can pass the complete set of values to another procedure as below and then split each pair and insert
eg: #DocKey1, #DocValue1 and #DocKey2, #DocValue2 etc
#DocKey1, #DocValue1, #DocKey2, #DocValue2, #DocKey3, #DocValue3, #DocKey4, #DocValue4, #DocKey5, #DocValue5
Below is the procedure am using now to insert
Create PROCEDURE [dbo].[InsertDocValues]
(
#DocKey varchar(20),
#DocValue nvarchar(20)
)
AS
SET NOCOUNT ON;
BEGIN
INSERT INTO dbo.DocValues(
DocKey,
DocValue
)
VALUES(
#DocKey,
#DocValue
)
End
Please suggest

May be the below code would work for you.
Using user defined table type variable.
CREATE TYPE DocTable AS TABLE
(
DocKey int,
DocValue nvarchar(50)
);
GO
And then use this type to create required variable in first SP and pass the same to your second SP.
DECLARE #DocTable AS DocTable;
INSERT INTO #DocTable
SELECT #DocKey1, #DocValue1 UNION ALL
SELECT #DocKey2, #DocValue2 UNION ALL
SELECT #DocKey3, #DocValue3 UNION ALL
SELECT #DocKey4, #DocValue4 UNION ALL
SELECT #DocKey5, #DocValue5
You can create the above insert query dynamically also. There are so many ways to populate a table. So, use any one as you are getting output from your first SP.
And then call your Second SP.
EXEC [dbo].[InsertDocValues] #DocTable
Changes in second SP would be look like this.
Create PROCEDURE [dbo].[InsertDocValues]
(
#DocTable DocTable READONLY
)
AS
SET NOCOUNT ON;
BEGIN
INSERT INTO dbo.DocValues(
DocKey,
DocValue
)
SELECT
DocKey,
DocValue
FROM #DocTable
END

I'm getting the sense you have a string of pairs (key,value). Perhaps something like this:
Example
Declare #List varchar(max) = 'Key1:Value1,Key2:Value2'
Insert Into dbo.DocValues(DocKey,DocValue )
Select DocKey = left(RetVal,charindex(':',RetVal+':')-1)
,DocVal = stuff(RetVal,1,charindex(':',RetVal+':'),'')
From (
Select RetSeq = row_number() over (Order By (Select null))
,RetVal = ltrim(rtrim(B.i.value('(./text())[1]', 'varchar(max)')))
From (Select x = Cast('<x>' + replace((Select replace(#List,',','§§Split§§') as [*] For XML Path('')),'§§Split§§','</x><x>')+'</x>' as xml).query('.')) as A
Cross Apply x.nodes('x') AS B(i)
) A
The Data Inserted would be
DocKey DocVal
Key1 Value1
Key2 Value2
