Template:IssuerSlug
From LOTR-TCG Wiki
SQL expression (for use inside #cargo_query) giving the version-switch slug of a release's effective issuer: Decipher, PC or Other. These are the values of the data-issuer / data-set attributes that MediaWiki:Common.css keys on.
{{IssuerSlug}}: the releaseCR's own Issuer if set (errata), else its setCS's Creator.{{IssuerSlug|CR2}}for another CardReleases alias;set=names the CardSets alias (defaultCS).{{IssuerSlug|-}}: the set's issuer only.
Each column is compared on its own: CardReleases.Issuer and CardSets.Creator have different collations, so comparing {{IssuerName}} (an IFNULL of the two) to a string fails with "Illegal mix of collations".
