摘要:
Systems and methods are provided, wherein the method includes retrieving and/or storing one or more data types representative of a selected date and/or time value from a server to a client in a server/client SQL environment using a selected wire format. Another aspect provides apparatus including a SQL server, a SQL client operationally coupled to the server, and means to transmit the selected time/date data types between the server and the client according to a selected wire format. In an illustrative implementation, the wire format translates the date/time data into a binary format.
摘要:
Systems and methodologies that enhance a Tabular Data Stream (TDS) protocol by enabling efficient transmission of a row(s) with null columns(s). An identification component employs a bit map that can be positioned at beginning of a row, to indicate to the receiving side (e.g., a client) columns that are to be sent. Accordingly, by distinguishing columns that are null from columns that are not null—followed by sending columns that are not null—transmission resources can be effectively employed.

摘要:
Systems and methodologies that enhance a Tabular Data Stream (TDS) protocol by enabling clients to send tabular formed data as a single parameter to servers. A Table Valued Parameter (TVP) transporting component enables the client servers to transmit entire database tables as a single parameter; when invoking a server side procedure, for example. As such, values can be passed for functions associated with a stored procedure, and a parameter styled Application Program Interface (API) can be implemented.
