Compiling optimized database statements including receiving, by a query compiler from a client computing system, a state specification of a graphical user interface in response to a user manipulating the graphical user interface on the client computing system, wherein the state specification is in a standard file format and describes modifications to a plurality of visual elements of the graphical user interface; compiling, by the query compiler, a database statement from the state specification such that a limit clause within the database statement is processed by a database before at least one join clause; and sending, by the query compiler, the optimized database statement to a database on a cloud-based data warehouse.

Compiling optimized database statements

Adding a column into a worksheet, including: receiving, via a spreadsheet interface comprising a first worksheet, a request to add a new column to the first worksheet, wherein the request includes a key that identifies a reference column in the first worksheet, a specification of a second worksheet that comprises a corresponding reference column related by the key, and a specification of a data column in the second worksheet, wherein each entry of the data column is associated with an entry of the corresponding reference column in the second worksheet, and entries to be included in the requested new column will be based on the entries of the data column; generating, based on the request, a database query; and receiving, from a database and in response to the database query, a query result comprising the new column to be added to the first worksheet.

Optimizing database statements using a query compiler including receiving, by a query compiler from a client computing system, a state specification of a graphical user interface; compiling, by the query compiler, a database statement from the state specification, including: optimizing the database statement by repositioning, within the database statement, a limit clause such that the limit clause is processed by the database before at least one join clause; and sending, by the query compiler, the optimized database statement to a database on a cloud-based data warehouse.
