SQL One-to-Many Relationships and Retrieving Specific Rows from a Related Table Introduction In relational databases, one-to-many relationships between tables are common. A one-to-many relationship occurs when one row in a table (the “parent” or “one”) is associated with multiple rows in another table (the “child” or “many”). In this blog post, we will explore how to work with one-to-many relationships and retrieve specific rows from the related table using SQL.
