Sous-requête imbriquée T-SQL

Question

Je souhaite placer ce code de travail dans une instruction SQL, OU dois-je effectuer une fonction UDF.

Le jeu de résultats est une concaténation à une ligne, et je souhaite qu'il soit placé dans chacune des lignes de jeu de résultats globales.

Pas vraiment sûr de ce que vous demandez, mais vous pouvez faire quelque chose le long des lignes de

Select col1 + ', ' + col2 + ', ' + col3 etc....
