    Need to complete the rest of my assignment that I can&quot;t do - involves SQL and ER DiagramsQ.A group of people are setting up a car pooling arrangement and require a database to manage the information about pickup locations, drivers, passengers and the routes that will be driven. Use the following information to draw an ER diagram for the required database with the symbols and notation used in lectures and notes. You must not submit scanned or bit-mapped diagrams. This will result in reduced marks. A route is identified by a Route ID and has an associated departure time. There are many Pickup locations. Each one has a unique number known as an L number. There is also a description with details of precisely where the pickup is for that location.Each route is made up of many locations. Individual locations can appear on more than one route. People who register to use the service as a passenger are each given a P number and their name and mobile number is recorded. Other people register as drivers. They are each given their own D number and also supply their name and mobile number. Based on their needs, passengers in the system select the pickup location they prefer and record the time they expect to be at the pickup location. Routes are allocated to drivers. There are always more drivers than routes so every route has a driver. Each route starts and

    Please refer to the attachments. Export data from SQL server to excel using the pre-existing template. I require the query in the &quot;Requirements.doc&quot; to export data from SQL into an existing XLS file (not a new file - I can achieve this already). The pre-existing file is attached which includes all the pre-defined columns and all columns are formatted to the type of data that will be in each column. The export process of the data to XLS should be that of a stored procedure and should not alter the column headers - it should simply export the data to the XLS in to the designated columns i.e. PositionNo (SQL) > PositionNo (XLS).

    Have MSSQL Stored Procedure (&quot;SP&quot;) that has been running flawlessly for years on Win Server 2003 and MSSQL 2005. Moved app and database to Win Server 2012R2 64-bit and MSSQL 2008. SP functions to fetch data from database and propagate to Excel spreadsheet. Now have an issue with the SP involving the parameter for the &quot;Path to Excel Spreadsheet&quot; If path is entered as \Share\spreadsheet (e.g. E:\DD\5051.xls) it works fine. However if enteres as \\servername\share\spreadsheet (e.g. \\SUPCTCP\DD\5051.xls) it results in error message and failure. Using the Drive letter limits access to only those users who log on to the server itself. This SP needs to be run by client pcs on the network. There for we need to use the \\servername\ format. I can provide printout of the SP and screen shots of the success and failure. Successful candidate must be familiar with MSSQL and must have good diagnositc skills.
