select nombres a partir de IDs separados por coma en una columna
Hola

Necesito ayuda para escribir una consulta bastante compleja:

Tengo una tabla 'producttags' con ID y Nombre para cada tag.
Y otra tabla 'products' con una columna 'tags' que contiene IDs de varios tags, separados por comas (ej: 20,38,400)
Lo que necesito es hacer un select que me devuelva una columna con el nombre de los tags de cada producto, si es posible separados por un "#"

Alguien sabe como puedo lograr esto?
Si no se entiende avisenme y intento explicarlo mejor.

Es para un sitio bastante grande y con mucho trafico asi que deberia ser lo mas eficiente posible.

Muchas gracias!


No se si es relevante, pero les copio la consulta actual:
Como podran ver, los tags actualmente se levantan usando la tabla 'productjointags', pero el objetivo de esta modificacion es no necesitar mas esa tabla
