Mysql CASE - WHEN - THEN - returning wrong data type (blob)
- by Jack
Hi there.
Im creating customizable product attributes in a web store - each attribute can have different type of data, each data type is stored in a separate column using corresponding mysql datatype.
I Have a query like:
SELECT
products.id AS id,
products.sku AS sku,
products.name AS name,
products.url_key AS url_key,
attributes.name AS attribute,
CASE
WHEN `attribute_types`.`type` = 'text' THEN product_attribute_values.value_text
WHEN `attribute_types`.`type` = 'float' THEN product_attribute_values.value_float
WHEN `attribute_types`.`type` = 'price' THEN product_attribute_values.value_float
WHEN `attribute_types`.`type` = 'integer' THEN product_attribute_values.value_integer
WHEN `attribute_types`.`type` = 'multiple' THEN product_attribute_values.value_text
WHEN `attribute_types`.`type` = 'dropdown' THEN product_attribute_values.value_text
WHEN `attribute_types`.`type` = 'date' THEN product_attribute_values.value_date
WHEN `attribute_types`.`type` = 'textarea' THEN product_attribute_values.value_textarea
END as value
from (...)
Now, the problem is that when attribute_types.type equals to ?some-type? i want it to return a value as it's stored in product_attribute_values table.
Currently I get BLOb every time.
Should I use type-casting or there's some behind-the-scene magic that I dont know about, OR maybe there's some better alternative ?
