Upravit:
Za předpokladu, že jsou vaše výsledky takové :
Napište
number company db1 Count
1 SuperCorp 5
2 SuperCorp 10
Zpráva
number company db2 Count
2 SuperCorp 10
3 SuperCorp 20
Pokud chcete zobrazit tabulku, jako je tato
number company db1 Count db2 Count
1 SuperCorp 5 0
2 SuperCorp 10 10
3 SuperCorp 0 20
Než je chcete vytisknout na obrazovku, musíte výsledky těchto dvou dotazů sloučit. To je možné díky vašemu sloupci 'číslo', který lze použít jako klíč vašeho pole PHP.
Musíte také upravit své dotazy SQL tak, aby obsahovaly falešný sloupec představující počet ostatních databází:
$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 poté zkombinujte 2 předchozí výsledky, abyste je zobrazili takto:
$results = array();
while($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";
}
