The SSIS Import/Export Wizard lets the user create packages that move data from a single data source to a destination with no transformations. The Wizard can quickly move data from a variety of source types to a variety of destination types, including text files and other SQL Server instances.
In SQL Server versions 6.5 and earlier, database administrators (DBAs) used SQL Server Transfer Manager and Bulk Copy Program, included with SQL Server, to transfer data. These tools had significant shortcomings, and many [ quantify ] DBAs used third-party tools such as Pervasive Data Integrator to transfer data more flexibly and easily.
A UNION query could combine results from both tables. Note that UNION ALL does not guarantee the order of rows. Rows from the second operand may appear before, after, or mixed with rows from the first operand. In situations where a specific order is desired, ORDER BY must be used. Note that UNION ALL may be much faster than plain UNION.
Tabular Data Stream (TDS) is an application layer protocol used to transfer data between a database server and a client. It was initially designed and developed by Sybase Inc. for their Sybase SQL Server relational database engine in 1984, and later by Microsoft in Microsoft SQL Server .
The "Server port" column indicates the port from which the server transmits data. In the case of FTP , this port differs from the listening port. Some protocols—including FTP, FTP Secure , FASP , and Tsunami —listen on a "control port" or "command port", at which they receive commands from the client.
The ReportViewer control will process reports by: (a) server processing, where the report is rendered by the Report Server; or (b) local processing, where the control renders the RDL file itself. SQL Server Reporting Services also support ad hoc reports: the designer develops a report schema and deploys it on the reporting server, where the ...
In the field of programming a data transfer object (DTO [1] [2]) is an object that carries data between processes. The motivation for its use is that communication between processes is usually done resorting to remote interfaces (e.g., web services), where each call is an expensive operation. [ 2 ]
Conversely, an inner join can result in disastrously slow performance or even a server crash when used in a large volume query in combination with database functions in an SQL Where clause. [ 2 ] [ 3 ] [ 4 ] A function in an SQL Where clause can result in the database ignoring relatively compact table indexes.
