I have a large statement @SQL that can dynamically grow up to about 6000 characters.

I need to execute this statement using :

sp_executesql

since the stored procedure parameter accepts only a single variable and the + operator is not allowed, how can I execute this statement using this stored procedure?

AFAIK, you will have to use a type of NTEXT.  You could create the query in two 4000-char NVARCHAR variables then concatenate that into an NTEXT field.  Sorry, don't know any other way.

So how would I insert the ntext value (which as I understand it exists only as a table field) into the sp_executesql statement.

I worked up the following to test some ideas but haven't found any that work

declare @a nchar(3)
declare @b nchar(3)
set @a = N'sp_'
set @b = N'who'
declare @table table (sql ntext NULL)
insert into @table values (@a + @b)

--this doesn't work and so is where I need help
exec sp_executesql (select top 1 sql from @table)

I think it can be an input parameter to a SP, but can then be manipulated as desired once inside the SP.  Sorry, I meant to mention that earlier.  If this is this being done within a SP, hopefully that will help.
