Select count(*) INTO

Hi all,
I am creating a procedure and the following query produces a result of 1 when launched individually:

SELECT COUNT(*) as counter
FROM INFORMATION_SCHEMA.PARTITIONS
WHERE TABLE_SCHEMA = 'my_dwh'
AND TABLE_NAME = 'report_position'
AND PARTITION_NAME = 'p143';

why in the procedure I always have a value of 0?
This is my code:

...
DECLARE partition_count BIGINT UNSIGNED DEFAULT 0;

SELECT COUNT(*) AS counter
FROM INFORMATION_SCHEMA.PARTITIONS
WHERE TABLE_SCHEMA = 'my_dwh'
AND TABLE_NAME = 'report_position'
AND PARTITION_NAME = 'p143'
INTO partition_count;
...

Thank you in advance,

Andrea
