stmtsetFetchMode

The `stmtsetFetchMode` function is a method commonly found in database interaction libraries or APIs, particularly those that interface with SQL databases. Its primary purpose is to control how data is retrieved from a database query result set.

Specifically, `stmtsetFetchMode` allows a developer to specify the format or structure in which rows from the result set will be returned to the application. This can influence the efficiency and convenience of data processing. Common fetch modes might include returning rows as arrays of values, associative arrays (where column names are keys), objects (where column names are properties), or even as a stream of individual values.

The exact implementation and available options for `stmtsetFetchMode` can vary significantly depending on the programming language, the specific database driver, or the Object-Relational Mapper (ORM) being used. However, the underlying goal remains consistent: to provide flexibility in how query results are accessed and manipulated by the application. Developers often choose a fetch mode that best suits the immediate needs of their code, balancing performance considerations with ease of use. For instance, an associative array might be preferred for its readability when accessing specific columns by name, while a simple array might be more efficient for bulk processing where column order is known.
