The mechanism for dynamic SQL with parameters is as follows:

https://msdn.microsoft.com/en-us/library/ms188001.aspx

You'd want to create the declaration for your parameter definition:

DECLARE @ParmDefinition nvarchar(500);

Open in new window


then,

SET @ParamDefinition = N'@CustID bigint, @LName varchar(30), @FName varchar(30).....'

Open in new window


and then create a variable for each of your input variables,

DECLARE @CustomerID BIGITINT = 123456789
DECLARE @LastName VARCHAR(30) = 'Smith'

Open in new window

and so forth,

Call it:
EXEC sp_executesql @spexecutesqlStr , @ParamDefinition, @CustID = @CustomerID,
@Lname = @LastName, .....

Open in new window

Can you explain the new problems? This seems to work perfectly for me locally on my system.

i execute this

declare @spexecutesqlStr nvarchar(1000)

 DECLARE @ParmDefinition nvarchar(500);
 SET @ParmDefinition = N'@CustID bigint, @LName varchar(30), @FName varchar(30), @MI char(1), @Email varchar(128), @RegionNo tinyint, @CustomerCode tinyint'

 DECLARE @CustomerID BIGINT = 1
 DECLARE @LastName VARCHAR(30) = 'Achong'

 EXEC sp_executesql @spexecutesqlStr , @ParmDefinition,
             @CustID = @CustomerID,
             @Lname = @LastName,
             @FName = null,
             @MI = null,
             @Email =null,
             @RegionNo = null,
             @CustomerCode= null

the error is:
Msg 8178, Level 16, State 1, Line 0
The parameterized query '(@CustID bigint, @LName varchar(30), @FName varchar(30), @MI cha' expects the parameter '@LName', which was not supplied.

I copied and pasted all of that to my local SSMS and it works, but there is no definition for:
sp_executesql 

Open in new window

In your example that you posted. Do you have a more fully detailed demonstration of the problem?

All my local testing has worked with your examples. I can't determine what the problem is. Sorry. It works just fine in my local system. Could it be that we have different versions of SQL server that are causing the problems? I'm using 2012.

This works for me:

DECLARE @spexecutesqlStr NVARCHAR(1000) = 'EXEC dbo.GetCustomerInformation @CustomerID = @CustID, @LastName = @Lname'
DECLARE @ParmDefinition NVARCHAR (500) = N'@CustID bigint, @LName varchar(30), @FName varchar(30), @MI char(1), @Email varchar(128), @RegionNo tinyint, @CustomerCode tinyint'
DECLARE @CustomerID BIGINT = 1
DECLARE @LastName VARCHAR(30) = 'Achong'

 EXEC sp_executesql @spexecutesqlStr, 
					@ParmDefinition, 
					@CustID = @CustomerID,
					@Lname = @LastName,
					@FName = null,
					@MI = null,
					@Email =null, 
					@RegionNo = null, 
					@CustomerCode= null

Open in new window
