I am trying to create a view with the below query.
it should be a view as data in other tables will be updated and I want to refer to this often. Or as a last resort schedule the creation of this table over night some how?
DECLARE @@string1 varchar (20) = ' Number='
DECLARE @@string2 varchar (20) = ' And Id='
SELECT f.linkid, f.docname, f.title, dc.catname, t.template, r.extlink ,f.libid
,substring(extlink, charindex(@@string1, extlink)+len(@@string1),
charindex(@@string2, extlink) -len(@@string1) - charindex(@@string1, extlink)) as ID
from AL_TEMPLATE t
INNER JOIN AL_RELATION r ON t.tempID=r.tempid
INNER JOIN AL_RELATED_FILE rf ON r.relID=rf.relid
INNER JOIN al_file f ON rf.linkid=f.linkID
INNER JOIN al_filecats fc ON f.linkid=fc.linkid
INNER JOIN AL_DOCCAT dc ON fc.catid=dc.catID
where charindex(@@string2, extlink) -len(@@string1) - charindex(@@string1, extlink) > 0
Thanks

A view can only contain a single select statement, no other statements are allowed.

Try an in-line table-valued function with those two variables as parameters to the function.

I'm pretty sure you cant use variables in views, I have decided to take them out which isn't the end of the world.

I haven't worked out how to create a table on a scheduled task yet but i think the above method is better for this purpose.

Thanks

As Gail already suggested you can use inline table valued function and can pass those two parameteres in that..........
