I'm trying to enter values into a database table using a form and a PHP function. The PHP seems to be fine as the SQL statement it creates looks okay, but the database always throws up an error. This is the SQL statement that my code has generated (with arbitrary values):
INSERT INTO Iteminfo ('itemName', 'itemSeller', 'itemCategory', '...
What is the purpose of putting an 'N' in front of function parameters in TSQL?
For example, what does the N mean in front of the function parameter in the following code:

If all of the three flags are set to '1' then the query to be generated is
SELECT * FROM Food WHERE Name In ('Apple, 'Biscuit', 'Chocolate');
If only the flags 'A' and 'B' are set to '1' with C set to '0'. Then the fol...
Currently, our system will do a "foreach" over all Subscriptions which are returned from the ListSubscriptions method of ReportingService and fire a Timed Subscription event so that they receive the report as an email.
In our dev environment, I don't want every subscription of these reports to be sent out when we are testing.
Is there ...
I have a table of data that is searchable and sortable, but likely to produce hundreds or thousands of results for broad searches. Assuming the user searches for "foo" and sorts the foos in descending price order I'd like to show a quick-jump select menu like so:
<option value="1">Page 1 ($25,000,000 - $1,625,000)</option>

Hi, basically, I have 3 tables; users and projects, then I have 'users_projects' to allow the one-to-many formation. When a user adds a project, I need the project information stored and then the 'userid' and 'projectid' stored in the usersprojects table. It sounds like its really straight forward but I'm having problems with the syntax...

Note: The database is Microsoft Access.
