Hello,
I am trying to print the results of a simple query. ITEM is the first of four columns in my table, and is the only one I want to see the results from. But the browser only displays the basic info from the jsp code near the top of the program when I enter the url. I have marked the SELECT statement with a comment. Thanks!
The output...
MySQL-JSP, hello.delete mm.mysql.libdelete mm.mysql-2.0.3.lib
hello world
The current data and time isSun Dec 29 21:06:50 PST 2002 after DriverManager con!=null;1
after show table
con!=null;

It looks like you might not be getting any results from your query. Have you tried running it in the database itself to make sure it returns something?
Also, to test your code, try a simpler query, something like:
SELECT * FROM FOOD;
And make sure it is printing the results.
Another thing to do would be to test the resultset after it is returned to see if there are any items in it:

hope that helps

I tried the if statement with the do-while as well as the SELECT *, but am still getting the same output. My DBTools shows me those tables have the data. What could be going wrong? Thanks again.

Hi Doug,
1. Check the syntex for loading the Driver and Connection
2. All HTML tags in "quotes" in out.println instead of System
Hopefully you will get some result.
Thanks

The connection syntax was given to me by the webhost, and I'm positive that my database userid and password are correct. Should I ask the webhost what is going wrong? I'm not sure what you mean by quotes around html tags because the br tag does have quotes around it in the out.print statement.
Thanks!
