MSSQL - Join tables, in different databases, on the same server - sql-server

Question

I have 2 tables, in different databases, on the same server.
I would like to output the differences.
Database 1: dbo.employees
Table: employees
id name
--- ----
1 John
2 Ringo
3 Paul
4 George
Database 2: dbo.timecard
Table: time
timeid timename
--- ----
1 John
2 Ringo
3 Paul
Desired output:
resultid resultname
--- ----
4 George
I've set up the connection info:
<?PHP
$serverName = "server";
$UID = "dbuser";
$PWD = "dbpass";
$Database1 = "employees";
$Database2 = "timecard";
$connectionOptions1 = array("Database"=>$Database1, "UID"=>$UID, "PWD"=>$PWD);
$connectionOptions2 = array("Database"=>$Database2, "UID"=>$UID, "PWD"=>$PWD);
$conn1 = sqlsrv_connect( $serverName, $connectionOptions1);
$conn2 = sqlsrv_connect( $serverName, $connectionOptions2);
if( $conn === false )
var_dump(sqlsrv_errors());
?>
And created 2 queries:
<?PHP
$EmployeeSelect = sqlsrv_query($conn1,"SELECT * FROM dbo.employees ORDER BY name");
WHILE ($EmployeeFetch=sqlsrv_fetch_array($EmployeeSelect, SQLSRV_FETCH_ASSOC)){
ECHO $EmployeeFetch['name']." / ".$EmployeeFetch['id'];
ECHO "<BR>";
}
?>
<?PHP
$TimeSelect = sqlsrv_query($conn2,"SELECT * FROM dbo.timecard ORDER BY timename");
WHILE ($TimeFetch=sqlsrv_fetch_array($TimeSelect, SQLSRV_FETCH_ASSOC)){
ECHO $TimeFetch['timename']." / ".$TimeFetch['timeid'];
ECHO "<BR>";
}
?>
How does one deal with 2 different connection strings in a single query?

Answer 1

You don't need multiple connection strings since these are on the same server. Your connection will have a default database of whatever. Let's say your second query needs to pull data from another database than the default. You just need to use 3 part naming.
As a side note, you should always explicitly name your columns instead of using *.
Select *
from MySecondDatabase.dbo.timecard

Answer 2

I would run it as a single SQL statement instead:
SELECT E.*
FROM db1.dbo.Employee E
LEFT OUTER JOIN db2.dbo.Time T
ON E.name = T.timename
WHERE T.timename IS NULL

Answer 3

SELECT id,name FROM db1.dbo.Employee
EXCEPT
SELECT timeid,timename FROM db2.dbo.Time
