In SQL, a window function or analytic function [1] is a function which uses values from one or multiple rows to return a value for each row. (This contrasts with an aggregate function, which returns a single value for multiple rows.) Window functions have an OVER clause; any function without an OVER clause is not a window function, but rather ...
MySQL Workbench is the first MySQL family of products that offer two different editions - an open source and a proprietary edition. [31] The "Community Edition" is a full featured product that is not crippled in any way. Being the foundation for all other editions it will benefit from all future development efforts.
Excel 2.0 for Windows, which was modeled after its Mac GUI-based counterpart, indirectly expanded the installed base of the then-nascent Windows environment. Excel 2.0 was released a month before Windows 2.0, and the installed base of Windows was so low at that point in 1987 that Microsoft had to bundle a runtime version of Windows 1.0 with ...
Multics had a pwd command (which was a short name of the print_wdir command) [11] from which the Unix pwd command originated. [12] The command is a shell builtin in most Unix shells such as Bourne shell, ash, bash, ksh, and zsh. It can be implemented easily with the POSIX C functions getcwd() or getwd().
However, delete and update operations are more problematic: deletes must leave an empty space, or the rows' offsets would change; the same goes for updates, as the length of the rows becomes shorter; if the update makes the row longer, the row is fragmented. To defragment rows and claim empty space, the OPTIMIZE TABLE command must be executed.
DR DOS 6.0 [11] and Datalight ROM-DOS [12] include an implementation of the find command. The FreeDOS version was developed by Jim Hall and is licensed under the GPL. [13] The Unix command find performs an entirely different function, analogous to forfiles on Windows. The rough equivalent to the Windows find is the Unix grep. [14]

The command is also available in the Command Processor Shell of Windows Embedded CE [6] and in the Take Command Console. [7] Although the OS/2 command shell is closely related to the Windows Command Prompt, the title command is not available in the OS/2 version of cmd.exe. The default title of the OS/2 shell window is "OS/2 Window".
