Well, the problem is that I am trying to join two tables.
Table series looks like this:
Serie 1Serie DescriptionDate updatedetc, etc
Serie 2Serie DescriptionDate updatedetc, etc
Serie 3Serie DescriptionDate updatedetc, etc
Serie 4Serie DescriptionDate updatedetc, etc
Table articles looks like this:
Article idSerie 1Article descetc, etc
Article idSerie 1Article descetc, etc
Article idSerie 2Article descetc, etc
Article idSerie 2Article descetc, etc
Article idSerie 2Article descetc, etc
Article idSerie 2Article descetc, etc
Article idSerie 2Article descetc, etc
Article idSerie 3Article descetc, etc
Article idSerie 3Article descetc, etc
Article idSerie 3Article descetc, etc
Article idSerie 4Article descetc, etc
I thought LEFT JOIN was the best way to combine the two...
