Zakładając, że wyniki są takie:
Napisz
number company db1 Count
1 SuperCorp 5
2 SuperCorp 10
Zgłoś
number company db2 Count
2 SuperCorp 10
3 SuperCorp 20
Jeśli chcesz wyświetlić taką tabelę
number company db1 Count db2 Count
1 SuperCorp 5 0
2 SuperCorp 10 10
3 SuperCorp 0 20
Musisz scalić wyniki dwóch zapytań przed wydrukowaniem ich na ekranie. Jest to możliwe dzięki kolumnie 'number', która może być użyta jako klucz tablicy PHP.
Musisz również zmodyfikować swoje zapytania SQL, aby zawierały fałszywą kolumnę reprezentującą inną liczbę baz danych:
$sql1 = "SELECT num.number AS Number, com.name As company, count(*) As \"db1 count\", 0 As \"db2 count\"
FROM db1.db.job_processing AS jp
LEFT JOIN db1.db.number AS num ON num.id=jp.number_id
LEFT JOIN db1.db.company AS com on com.id=num.company_id
WHERE jp.show=1 AND jp.processing_complete=1
AND jp.call_start_time BETWEEN '2016-12-17' AND '2017-01-03'
GROUP BY Number
ORDER BY Number
LIMIT 20";
$sql2 = "SELECT num.number AS Number, com.name AS company, COUNT(*) AS \"db2 Count\", 0 As \"db1 count\"
FROM db2.db.job_processing AS jp
LEFT JOIN db2.db.number AS num ON num.id=jp.number_id
LEFT JOIN db2.db.company AS com on com.id=num.company_id
WHERE jp.show=1 AND jp.processing_complete=1
AND jp.call_start_time BETWEEN '2016-12-17' AND '2017-01-03'
GROUP BY Number
LIMIT 20";
A następnie połącz 2 wyniki wcześniej, aby je wyświetlić, w ten sposób:
$results = array();
while($row = $result1->fetch_assoc()) {
//Adding all the 1st query results
$results[$row['number']] = $row;
}
while($row = $result2->fetch_assoc()) {
if(! isset($results[$row['number']]) {
//Mean's this row is not present in the 1st database, so add it
$results[$row['number']] = $row;
}else {
//Just merging the db2 Count from the 2nd database since other fields are the same
$results[$row['number']]['db2 Count'] = $row['db2 Count'];
}
}
if ($results) {
echo"<TABLE><caption>Total Call Count Overview</caption><TR>
<TH>Number</TH>
<TH>Company</TH>
<TH>db1 Count</TH>
<TH>db2 Count</TH></TR>";
foreach($results as $row) {
echo"<TR><TD>". $row["number"]. "</TD>";
echo"<TD>". $row["company"]. "</TD>";
echo"<TD>". $row["db1 Count"]. "</TD>";
echo"<TD>". $row["db2 Count"]. "</TD></TR>";
}
echo"</TABLE>";
} else {
echo"0 Results";
}
