"The DB-API 2.0 specification (PEP 249) defines several ways to pass parameters to SQL queries. The two most popular are: positional ? placeholders with a tuple/list of values and named %(name)s placeholders with a dictionary of values."
"Previously, mssql-python only supported qmark. It works fine for simple queries, but as parameters multiply, tracking their order becomes error-prone, leading to subtle, hard to spot bugs."
"With dual parameter style support, developers no longer need to choose between conciseness and clarity, making it easier to build complex queries and dynamically assemble filters."
mssql-python now supports both positional and named parameter styles for SQL queries, allowing developers to choose based on preference. Positional parameters can lead to confusion with multiple values, while named parameters offer clarity. This dual support is beneficial for complex queries, dynamic filters, and migrating existing code. The DB-API 2.0 specification defines these parameter styles, with positional placeholders represented by '?' and named placeholders by '%(name)s'. The new feature aims to improve high-performance SQL Server connectivity in Python applications.
