It is often useful or necessary to know what identity value was generated by an INSERT command. Microsoft SQL Server provides several functions to do this: @@IDENTITY provides the last value generated on the current connection in the current scope, while IDENT_CURRENT(tablename) provides the last value generated, regardless of the connection or scope it was created on.
Similar to MS SQL Server, it uses a BIT data type. [18] In Access it is known as a Yes/No data type [19] which can have two values; Yes (True) or No (False). The BIT data type in Access can also can be represented numerically; True is −1 and False is 0. [20] This differs to MS SQL Server in two ways, even though both are Microsoft products:
In computing, the working directory of a process is a directory of a hierarchical file system, if any, [nb 1] dynamically associated with the process. It is sometimes called the current working directory (CWD) , e.g. the BSD getcwd [ 1 ] function, or just current directory . [ 2 ]
In fact, any product that adheres to the object-oriented aspects of SQL:1999 could be described as an object–relational database management product. For example, IBM Db2, Oracle Database, and Microsoft SQL Server, make claims to support this technology and do so with varying degrees of success.
The pushd ('push directory') command saves the current working directory to the stack then changes the working directory to the new path input by the user. If pushd is not provided with a path argument , in Unix it instead swaps the top two directories on the stack, which can be used to toggle between two directories.
The Ident Protocol is designed to work as a server daemon, on a user's computer, where it receives requests to a specified TCP port, generally 113. In the query, a client specifies a pair of TCP ports (a local and a remote port), encoded as ASCII decimals and separated by a comma (,).
Microsoft SQL Server Compact (SQL CE) is a discontinued relational database produced by Microsoft for applications that run on mobile devices and desktops. Prior to the introduction of the desktop platform, it was known as SQL Server for Windows CE and SQL Server Mobile Edition. It includes both 32-bit and 64-bit native support. [1]
