Why does this function work one way in MSSQL Studio and another when accessed via PDO?
I'm trying to troubleshoot a function that's part of a SELECT statement. I built a little sandbox so I could better manipulate / view the code in a PHP environment. But when I went to fire the code, I got some different results and I don't understand why.
Here's the SQL:
When you fire that in MSSQL Studio, you get this:
Notice the value you're getting for "StatementRollUp."
Now when I try to run the same SELECT using a PDO dynamic, I get this:
...notice the value of "StatementRollUp."
In the Studio, StatementRollUp is "1." When I run it via PDO, it's "0" and I don't understand why.
Here's my PDO code:
What am I missing?
Here's the SQL:
SELECT
ac.AccountID,
clt.ClientName,
clt.ClientTetrisID,
clt.ClientID,
cast(dbo.ufn_ClientPreference(clt.ClientID, 'StatementRollUp') as int) as StatementRollUp
from Statement st with (nolock)
Join Account ac with (nolock) on st.Accountid = ac.AccountID
join Patient pat with (nolock) on pat.AccountID = ac.AccountID
join Practice prt with (nolock) on ac.PracticeID = prt.PracticeID
join Client clt with (nolock) on prt.ClientID = clt.ClientID
left join
(select pmtplanamount, pmtplanday, primarypatientid, startingplanbalance from PaymentPlan
where planendeddate is null
and iscurrentplan = 1) pp
on pp.primarypatientid = pat.patientid
where ac.accountid=10093227

$mssql_pdo->setAttribute(PDO::ATTR_ERRMODE,PDO::ERRMODE_EXCEPTION);

Who is Participating?
Scott!
I appreciate your time, friend! I'm up against a deadline so I'm glad you're at your desk! BTW: I'm in Nashville, so good to be talking to fellow Tennessean!
I should've provided the function. Here it is:
If you're like most, you're looking at this and wondering "Who wrote this?" I know. But be that as it may, I've got to understand what it's doing and how so I can determine conclusively whether or not it's posing a problem.
It works when I fire it in Studio, but it gives me a 0 when I run in PDO. Why the disparity?

Scott, I've run into this on a couple of situations since posting this question. I was able to solve the problem I was working on, but for the sake of establishing a bottom line, I'm going to close this question, but if I'm what I'm getting ready to suggest here inspires you to add any commentary, please do.
This particular app uses pconnect to connect to a T-SQL database. Not sure if pconnect has any advantages over PDO, but I've encountered situations where PDO sometimes coughs and sputters a little bit when it interacts with functions and stored procedures on the server. I remember one project where we boiled it down to a temp table being constructed within a stored procedure that was causing a problem. When we reconfigured that proc, it worked fine.
Whether or not that was an example of something that applies across the boards, I'm not sure. What I did this time around to circumvent even the possibility of an inconsistency is I built a little "sandbox" that used the same database connection as the actual app.
There you have it! Thanks for weighing in!
