Change Details

Allow to support prepare/bind/execute query workflow. This made easier to write better DI-resistant code. This change introduces a Query abstract class, implemented by PDOQuery, where the following method can prepare the query: - `query` to run the query and get PDODatabaseResult - `withValue` and `bind` to set a parameter value or bind it to a variable - `bindInOutParameter` to set a parameter for stored procedure calls The PDOQuery instance is constructed by PDOEngine classes, calling the `prepare()` method with SQL query as argument. While PDO directly calls all methods on statement class, this engine / query / result division supports better separation of concerns Ref T2169

Enhances support for the prepare/bind/execute query workflow, making it easier to write Dependency Injection (DI) resistant code. This change introduces a `Query` abstract class, implemented by `PDOQuery`, with the following methods: - `query: executes the query and returns a `PDODatabaseResult` - `withValue` and `bind`: sets a parameter value or bind it to a variable - `bindInOutParameter`: sets a parameter for stored procedure calls The `PDOQuery` instance is created by the `PDOEngine` class, which calls the `prepare()` method with an SQL query as its argument. While PDO directly calls all methods on the statement class, this engine/query/result separation improves the overall separation of concerns. Ref T2169
