EXEC sp_executesql with multiple parameters

问题

How to pass the parameters to the EXEC sp_executesql statement correctly?

This is what I have now, but i\'m getting errors:

alter PROCEDURE [dbo].[usp_getReceivedCases]
    -- Add the parameters for the stored procedure here
    @LabID int,
    @RequestTypeID varchar(max),
    @BeginDate date,
    @EndDate date
AS
BEGIN
    -- SET NOCOUNT ON added to prevent extra result sets from
    -- interfering with SELECT statements.
    SET NOCOUNT ON;


declare @statement nvarchar(4000)

set @statement = N\'select   SentToLab,
FROM     dbo.vEmailSent
WHERE     SentToLab_ID=@LabID and convert(date,DateSent) >= @BeginDate 
and CONVERT(date, datesent) <= @EndDate
and RequestType_ID in ( @RequestTypeID )

EXEC sp_executesql  @statement,N\'@LabID int\',  @LabID, N\'@BeginDate date\', @BeginDate,N\'@EndDate date\', @EndDate, @RequestTypeID=@RequestTypeID

END

RequestTypeID is a comma delimited list of integers, like so: \"1,2,3,4,5\"

here is my try #2, also unsuccessful

declare @statement nvarchar(4000)

SET @statement =\' select    SentToLab_ID

FROM     dbo.vEmailSent
WHERE     
SentToLab_ID=\'+@LabID+\' and convert(date,DateSent) >= \'+@BeginDate +\'
and CONVERT(date, datesent) <= \'+@EndDate+\'
and RequestType_ID in (\'+ @RequestTypeID+\' )
group by FileStream_ID, SentToLab_ID\'


EXEC(@statement)

Operand type clash: date is incompatible with int

Here is a simple example:

EXEC sp_executesql @sql, N'@p1 INT, @p2 INT, @p3 INT', @p1, @p2, @p3;

Your call will be something like this

EXEC sp_executesql @statement, N'@LabID int, @BeginDate date, @EndDate date, @RequestTypeID varchar', @LabID, @BeginDate, @EndDate, @RequestTypeID

This also works....sometimes you may want to construct the definition of the parameters outside of the actual EXEC call.

DECLARE @Parmdef nvarchar (500)
DECLARE @SQL nvarchar (max)
DECLARE @xTxt1  nvarchar (100) = 'test1'
DECLARE @xTxt2  nvarchar (500) = 'test2' 
SET @parmdef = '@text1 nvarchar (100), @text2 nvarchar (500)'
SET @SQL = 'PRINT @text1 + '' '' + @text2'
EXEC sp_executeSQL @SQL, @Parmdef, @xTxt1, @xTxt2
