I have a stored procedure where I'm looping through results in a cursor. The issue I'm having is the license_attributes value is always null when it shouldn't be. If I execute the select statement outside the stored procedure, or as a debug execute the select statement outside the cursor in the stored procedure, I get the results I'm expecting (not null)
This is the part of the select that is always returning null in the cursor:
(SELECT
CONCAT('{""',sf.Asset_Attribute__c.Type__c,'"": {',GROUP_CONCAT(
'""',sf.Asset_Attribute__c.Key__c,'"":""',LOWER(sf.Asset_Attribute__c.Value__c),'""'
),'}}')
FROM
sf.Asset_Attribute__c
WHERE
sf.Asset_Attribute__c.Asset__c = license_id
GROUP BY sf.Asset_Attribute__c.Asset__c) AS `license_attributes`
Here is the section of the stored proc:

But the results inside the block show license_attributes as null:
company, license_status, license_id, cloud_owner_email, entitlement_plan, role, is_trial, license_attributes
Test Company, Active, 02iq0000000jKgMAAU, [email protected], Standard, Owner, 0, null
Test Company, Active, 02iq0000000xlBBAAY, [email protected], Standard, Admin;wcl_admin;wcl_support, 0, null
Any help is greatly appreciated!
I suspect the issue is related to the procedure variable license_id.
The correlated subselect in the SELECT list includes
WHERE sf.Asset_Attribute__c.Asset__c = license_id
^^^^^^^^^^
Local variables take precedence over column references. Since license_id is declared as a variable within the code block,
DECLARE license_id VARCHAR(18) DEFAULT null;
the reference to license_id in the SELECT statement is a reference to that procedure variable.
Outside the code block, there likely is not a local variable named license_id. So that same SQL SELECT statement, that reference to license_id is not a reference to a variable, but a reference to a column.
I haven't traced through all of the logic, or the contents of license_id variable. But I suspect that explains the difference in the behavior observed with the statement, executed inside the code block vs outside the block.
