Copilot for Data Warehouse provides intelligent autocomplete-style T-SQL code suggestions to simplify your coding experience.
As you start writing T-SQL code or comments in the editor, Copilot for Data Warehouse leverages your warehouse schema and query tab context to complement the existing IntelliSense with inline code suggestions. The completions can come in varied lengths - sometimes the completion of the current line, and sometimes a whole new block of code.
