Query to add up multiple names from TVP - sql-server

Question

I have a table of name value pairs like this
Properties
- EmployeeId
My table for employee looks like this:-
EmployeeId FirstName Middle LastName
1 John Smith
2 Rick Steve James
3 Maddy Y Angela
Now my TVP can contain multiple or single EmployeeId's
I want to add up the full names of all the person in TVP in a single parameter.
i.e.
For eg. If I receive 1 and 3 in TVP
My output should be John Smith, Maddy Y Angela.
Do I need to use cursors in this?
What is the best way to accomplish this?
EDIT
The Scipt For the TVP is as below:-
CREATE TYPE [dbo].[Employee] AS TABLE( [EmployeeId] [uniqueidentifier] NULL)GO
The desired output is the Full Names of Employees in the TVP comma seperated.

Answer 1

Assuming you have a table type like:
CREATE TYPE dbo.TVPTypeName AS TABLE(EmployeeId INT PRIMARY KEY);
Then you can just perform a join:
CREATE PROCEDURE dbo.foo
#bar dbo.TVPTypeName READONLY
AS
BEGIN
SET NOCOUNT ON;
SELECT STUFF((SELECT ','
+ e.FirstName
+ COALESCE(' ' + NULLIF(RTRIM(e.Middle),''), ' ')
+ e.LastName
FROM dbo.Employees AS e
INNER JOIN #bar AS b
ON e.EmployeeId = b.EmployeeId
FOR XML PATH(''),TYPE).value('.[1]','nvarchar(max)'),1,1,'');
END
GO

Answer 2

CREATE TYPE dbo.IntArray AS TABLE(IntValue INT PRIMARY KEY);
GO
CREATE TABLE dbo.Employee(
EmployeeID INT IDENTITY(1,1) PRIMARY KEY,
FirstName NVARCHAR(50) NOT NULL,
MiddleName NVARCHAR(50) NULL,
LastName NVARCHAR(50) NOT NULL
);
GO
INSERT INTO dbo.Employee VALUES ('John',NULL,'Smith');
INSERT INTO dbo.Employee VALUES ('Rick','Steve','James');
INSERT INTO dbo.Employee VALUES ('Maddy','Y','Angela');
GO
CREATE PROCEDURE dbo.CocoJambo(#pEmployee dbo.IntArray READONLY)
AS
BEGIN
DECLARE #Result NVARCHAR(MAX);
SELECT #Result=ISNULL(#Result,'')+','+FirstName+ISNULL(' '+MiddleName,'')+' '+LastName
FROM dbo.Employee e INNER JOIN #pEmployee p ON e.EmployeeID=p.IntValue;
SELECT STUFF(#Result,1,1,'') AS [Result];
END;
GO
-- Test
DECLARE #p dbo.IntArray;
INSERT INTO #p VALUES (1);
INSERT INTO #p VALUES (3);
EXEC dbo.CocoJambo #pEmployee=#p;
/*
Result
-------------------------
John Smith,Maddy Y Angela
