WebMatrix tip: renaming SQL tables (and running SQL commands)
Here's a tip that came up on an internal alias today. When you create a database table in WebMatrix, you click the New Table button in the ribbon, define your fields, and then save. The save process gives you your one and only chance to name the table:
If you screw this up, tho, or if you change your mind about the name, you'll find yourself pressing F2 in vain to try to get it to let you rename the table.
However, you can use the sp_rename command to, you know, rename the table. In the Databases workspace, select the database and then in the riboon click New Query. This displays what's basically a free-form edit window. Click inside and enter a command like this:
sp_rename 'Customres', 'Customers'(note the single quotation marks around the names) and then click Execute in the ribbon.
Assuming everything went well, you'll see a results window:
The larger lesson here is that you can execute arbitrary SQL commands in the New Query window. For info about what-all you can do in SQL Server Compact, have a look at the SQL Reference (SQL Server Compact) page on MSDN. Note that commands for SQL Server Compact have some limitations. For example, sp_rename only lets you rename tables, unlike its equivalent in "big" SQL Server.
