Use one single generic SQL Left Pad string function (LeftPad) for any built-in LPAD function or its emulation with a SQL expression. This article walks through in detail over the generated SQL when LPAD was supported or not. Select LeftPad from our visual SQL query builder, and it will be translated into the appropriate call.

Design SQL queries with window functions and reusable OVER clause declarations, regardless of whether or not your database supports the standard SQL WINDOW definition. Design visual SQL queries using MySQL window functions through Data Xtractor. Generate reusable WINDOW definitions, or simply isolate a reusable OVER clause in the visual designer.

This permanently updated list shows all database products with built-in native support for Window Functions. This includes the OVER clause, named windows or window chaining with the WINDOW clause, together with ranking functions, offset navigational functions and other related functions.

When complex SQL queries are generated for you, there is no need to expose SQL’s complexity when you handle some functions.

You can much better understand how ROWS works after playing for just a few minutes with our visual SQL query builder for window functions.
