Merge Data for N-N Relationship Tables in T-SQL
Recently, I have been organizing my blog data and needed to perform an operation to merge article categories. On my blog, articles and categories have a many-to-many relationship. That is, one article can belong to multiple categories, and one category can contain multiple articles. This is a very typical many-to-many relationship, and I use a many-to-many table with a composite primary key to associate this data. What I need to do is move articles from the "DotNetBeginner" category to the "CSharpAndDotNet" category. However, since some of the articles originally in the "DotNetBeginner" category also belong to "CSharpAndDotNet", directly updating the association table would result in duplicate composite keys, which would cause issues.
