, I have another case where I need to use EXECUTE TO UPDATE certain table, and also to INSERT...
DECLARE @tbl nvarchar(125), @lookupvalue nvarchar(125), @lookuporder nvarchar(125), @lvid nvarchar(125)
I want to use those variable for UPDATE... using EXEC sp_executesql...
SET @sql=('UPDATE @tbl SET fieldname=@fieldname, lookupvalue=@lookupvalue, lookuporder=@lookuporder WHERE lvid=@lvid')
EXEC sp_executesql @sql, N'@lvid nvarchar(125), @lookupvalue nvarchar(125), @lookuporder numeric(9), @fieldname nvarchar(125), @tbl nvarchar(125)'....im not sure what code to fill in here.
I will also use the same variables(except @lvid) for INSERT to @tbl.
I just want my StoredProcedure to be flexible.
Need Help...

You also need to learn sql programming. This is basically the worst possible way to use sql server's stored proc. You need to create one statement for each possible operation if you want to harnest the server's power.

I agree. You either have the cat by the tailpiece, or you are giving us insufficient info, hehehe .

Anyway, you can use at least some of this:

Replace the BOLD RED with your values...

DECLARE @SQL nvarchar(4000),

@fieldname nvarchar(50),

@tbl nvarchar(125),

@lookupvalue nvarchar(125),

@lookuporder nvarchar(125),

@lvid nvarchar(125)

SET @fieldname = 'FIELDNAME'

set @tbl = 'TBL'

set @lookupvalue = 'LOOKUPVALUE'

set @lookuporder = 'LOOKUPORDER'

set @lvid = 'LVID'

SET @sql = 'UPDATE ' + @tbl + ' SET fieldname=' + @fieldname + ', lookupvalue='

set @sql = @SQL + @lookupvalue + ', lookuporder=' + @lookuporder + ' WHERE lvid=' + @lvid

print @SQL --use this to check first

EXEC @SQL
