Jag antar att din month_payment
kolumnen är en DATE
(btw, bör posta SHOW CREATE TABLE
när du ställer SQL-frågor så att vi inte behöver gissa).
Men din första fråga formaterar inte det till år/månad. Det begränsar inte heller datumintervallet.
SELECT
GROUP_CONCAT(DISTINCT
CONCAT(
'SUM(CASE WHEN EXTRACT(YEAR_MONTH FROM month_payment) = ',
EXTRACT(YEAR_MONTH FROM month_payment),
' THEN AMOUNT END) AS `',
EXTRACT(YEAR_MONTH FROM month_payment),
'`'
)
) INTO @sql
FROM record_payment
WHERE month_payment BETWEEN ? AND ?

Trots Barmars förslag finns det ingen anledning att lägga detta i en lagrad procedur. Du taggade din fråga med PHP, och du kan göra detta i PHP alldeles utmärkt:
<?php
...get a PDO connection...
$sql = "
SELECT
GROUP_CONCAT(DISTINCT
CONCAT(
'SUM(CASE WHEN EXTRACT(YEAR_MONTH FROM month_payment) = ',
EXTRACT(YEAR_MONTH FROM month_payment),
' THEN AMOUNT END) AS `',
EXTRACT(YEAR_MONTH FROM month_payment),
'`'
)
) AS `pivot_columns`
FROM record_payment
WHERE month_payment BETWEEN ? AND ?
";
$stmt = $pdo->prepare($sql);
$date_from = '2017-01-01';
$date_to = '2017-08-01';
$stmt->execute([$date_from, $date_to]);
$row = $stmt->fetch();
$stmt->closeCursor();
$pivot_columns = $row['pivot_columns'];
$sql = "
SELECT title AS `Payment Method`, {$pivot_columns}
FROM record_payment t1
JOIN setting_payment_method spm ON spm.id = t1.method_id
WHERE month_payment BETWEEN ? AND ?
GROUP BY title WITH ROLLUP
";
echo $sql;
$stmt = $pdo->prepare($sql);
$stmt->execute([$date_from, $date_to]);
$results = $stmt->fetchAll();
$stmt->closeCursor();
print_r($results);
