1 1 Working with MS SQL Server

2 2 Objectives You will be able to Use Visual Studio for GUI based interactive access to a Microsoft SQL Server database. Populate a table with data from an Excel worksheet. Use sqlcmd for command line interactive access to a Microsoft SQL Server database. Using either Visual Studio or sqlcmd Create and delete tables. Modify table definitions. Insert new rows into tables. Modify existing rows. Retrieve and display table data.

3 3 We all have accounts, with own database, on a Microsoft SQL Server on the CoE network: scorpius.eng.usf.edu Classroom and lab computers can access the CoE database directly. A VPN is required for your home computer or wireless laptop to access the CoE database server. Or maybe not! CoE Resources

4 4 VPN Software Download VPN client software can be downloaded from Academic Computing: http://vpn.usf.edu Caution: Some network oriented software on your computer may not work correctly while you have the VPN connection in place. Example: Sending Email

5 5 Setting Up a VPN Connection

6 6

7 7 Click Start

8 8 The Connection is Up This is Windows XP. The window will be different on other systems, but you should see the same information. If you don't get a window similar to this, your connection has not been established.

9 9 Using Visual Studio 2008 Visual Studio 2008 includes database access functions. View "Server Explorer" Set up a Data Connection

10 10 Data Connections in Visual Studio 2008 Right click on Data Connections and select Add Connection.

11 11 Adding a Data Connection

12 12 Adding a Data Connection Your SQL Server Username Your SQL Server Password

13 13 Test the Connection Click here

14 14 Adding a Table We will create a new table to hold the addresses in file Addresses.csv.

15 15 Adding a Table

16 16 Adding a Table

17 17 Data Types Common SQL Data Types int nvarchar(n)n = max number chars char(n)n = number chars decimal (p,s)p = total number of digits s = number decimal places datetime Many more!

18 18 Setting an ID Field It is good practice to include an ID field for every row. Unique identifier Not present in the Excel worksheet.

19 19 Setting an ID Field We will designate this as the “Primary ID”

20 20 Setting the Primary Key Right Click here System ensures that the Primary Key is unique.

21 21 Define Other Columns

22 22 Save the Table Definition Save

23 23 Table "Addresses" is Now Present

24 24 Viewing Table Data Right click on Addresses and select “Show Table Data”.

25 25 Viewing Table Data Table is currently empty.

26 26 Populating a Table Download file Addresses.csv from the Downloads area of the class web site: http://www.cse.usf.edu/~turnerr/Software_Systems_Development/ Downloads/ File Addresses.csv http://www.cse.usf.edu/~turnerr/Software_Systems_Development/ Downloads/ Double click to open in Excel

27 27 Excel Worksheet

28 28 Add ID Field In order to use this data in the database table we need to add an ID field. In Excel (2007), right click on the column header “A” and select “insert” in the dropdown menu. Adds a new column.

29 29 Adding an ID Column

30 30 Setting ID Values Set the ID for the first row to 1. Select ID on second row Press = Click the cell above (ID of the first row) Click in the formula window and add “+1” Formula window should now say =A1+1

31 31 Setting ID Values Press Enter

32 32 Setting ID Values

33 33 Setting ID Values Copy the formula in 2A down into all the cells below it. Click on 2A Shift click on 175A Press Ctrl-d (to copy Down) Should now see consecutive numbers 1 – 175 in the first column

34 34 Addresses with IDs

35 35 Populating the Database Table We will use the contents of this Excel worksheet to populate the Address table in the database. Click inside the worksheet, then press Ctrl-A to select all. Press Ctrl-C to copy the entire worksheet to the clipboard.

36 36 Populating the Database Table Click here to select all of the table. Press Ctrl-V to paste the clipboard into the table. (This may take a while to complete.)

37 37 The Table is Populated

38 38 The sqlcmd Utility Command line utility for MS SQL Server databases. Previous version called osql Available on classroom and lab PCs. In Windows command window Connect to a Database Server Enter SQL commands on the command line. Results output to the console.

39 39 Getting and Installing sqlcmd Included with Management Studio Express. Free download from Microsoft, Documentation available in SQL Server 2005 Books Online Free download from Microsoft. In Visual Studio 2008, search for sqlcmd.

40 40 The SQL Language The following slides demonstrate SQL commands using the sqlcmd program. Remember SQL is used everywhere we interact with a database server: Command line Database management programs Our own programs

41 41 Using sqlcmd The Server My Username Password entered here Execute commands in buffer Continued next class.
