stp2y0 CommentsNewscoding, community, development, engineering, inclusive, software

BackgroundApplications may need to work based on different databases. Although the SQL syntax for various databases is generally consistent, differences still exist, which necessitates modifications to related SQL statements. Such modifications often require manual adjustments, which involve heavy workload and are error-prone. Fully automating the SQL transformation is nearly impossible due to the varying functionalities of different databases. However, upon closer examination, it becomes clear that most issues stem from differences in the syntax of SQL functions. Especially for functions related to dates and strings, there isn’t a standard in the field, and each database has its own approach. For…

You can transform the elements in a Stream for further processing by extracting values from objects (e.g. getting the city name from a person or calculating the length of a string) and filter elements (e.g. only persons older than x years or cities starting with "D") before consuming the resulting Stream of elements.
