SQL Apprentice Question
am a newly indoctrinated SQL Server 2005 user. So, forgive me if this
question is amatuer.
I am trying to create a stored proc that will read in a list of values
from one table (Possibly using a cte?) then iterate through each record
running another sp to populate a temp table and return all matching
records. The logic would be like the following:
create procedure spSample1
create table #tmptbl
(tmptblcol1 int not null)
with samplecte (var1 int)
(select column1 from table where column2 = @column2)
while not end-of-file
set localvar1 = current value of samplecte var1
insert into #tmptbl exec spSample2 localvar1
This is a very rough outline. Hopefully it helps with clarification of
what I am trying to acheive. Any help would be greatly appreciated.
Thank you in advance!

Let's get back to the basics of an RDBMS. Rows are not records; fields
are not columns; tables are not files; there is no sequential access or
ordering in an RDBMS, so "first", "next" and "last" are totally
SQL is a declarative set-oriented language. We tend to write one
statement to do a job; if I want to insert data into a table, I write
INSERT INTO Foobar (a, b, c, ..)
SELECT x, y, z, ..
FROM Floob, Snarf, ..
One statement, no loops, no if-then control flow. You tell SQL
**what** you want, not **how** to do it. You want to write code as if
you were still in a 3GL procedural language. And I'll bet that your
schema is full of redundancies, too.

Nope, it was too vague to be usable for any concrete suggestions. But
it did demonstrate that you missed the very foundations of RDBMS. Get
a few books (insert shameless plug for my stuff here), clear out
everything you already know and start over. "To drink new tea, you
must first empty the old tea from your cup" - Zen proverb.
