Why is my row count 0?

Posted on 16th Feb 2014 by admin

Here's the MySQL query i'm running. It basically pulls data from 2 tables based on some data passed.

Here are things i know.
1. The data passed is passed correctly, and is correct as far as data goes.
2. The sql statements do run, the database connection is solid and works.
3. Other queries work, this however is the first join query im attempting.
4. employee_directory is a regular table, but pcsmgr.mvx_phone_history_io is a table inside the pcsmgr SCHEMA on the database. hence the prefix in the table names.

My guess it that perhaps the fact that my SELECT fields have two periods? maybe i dunno.
pcsmgr.mvx_phone_history_io.extension for example.

Here's the query - please see if you can figure out why the $recordCount returns 0;
Code: <?php
#Check for this branch
$branchid_SQL = $brancharray[$key][0];
#===Find All People That Work for "filenumber" WITHIN EACH BRANCH
$sql_1 = "SELECT employee_directory.filenumber,
employee_directory.phone,
employee_directory.firstname,
employee_directory.lastname,
employee_directory.managerid,
employee_directory.departmentid,
employee_directory.branchid,
pcsmgr.mvx_phone_history_io.extension,
pcsmgr.mvx_phone_history_io.calldate,
pcsmgr.mvx_phone_history_io.calltype,
pcsmgr.mvx_phone_history_io.dur_seconds,
pcsmgr.mvx_phone_history_io.dur_minutes,
pcsmgr.mvx_phone_history_io.dist_pnums,
pcsmgr.mvx_phone_history_io.count_pnums,
pcsmgr.mvx_phone_history_io.dognet_user_id,
pcsmgr.mvx_phone_history_io.callcat
FROM pcsmgr.mvx_phone_history_io, employee_directory
WHERE employee_directory.managerid = '$DT_filenumber' AND
employee_directory.branchid = '$branchid_SQL' AND
employee_directory.filenumber = pcsmgr.mvx_phone_history_io.dognet_user_id";
$go_1 = oci_parse($conn, $sql_1);
oci_execute($go_1);
$result_1 = oci_fetch_assoc($go_1);
$recordCount = oci_num_rows($go_1);
echo $recordCount;
?>

-- NEW

just realised that by removing this line of code from the query
Code: <?php
AND employee_directory.filenumber = pcsmgr.mvx_phone_history_io.dognet_user_id
?>I actually get a result, an inaccurate one but a result none the less. So i guess the next question is whats wrong with that line?
