Sql updating multiple columns

I'm using stripslashes and urlencode before I update the columns but it only seems to work if I try to update 1 column at a time ?

ok, I've tried just updating 1 column (title, date, body) and they all work fine that way so why doesn't it work when Itry to update 3 at once ???

So I know that it has to be returning true, otherwise there'd be an error somewhere or I wouldn't receive the e-mails. Right after the query runs, in PHP, I would make another select query that redumps the row and check the value there. Then all you have to do is find where it's setting it back to the old value.

Hello SQL Server Readers, You've probably seen multiple column update examples out there using syntax such as this: set (col1, col2) = (select col1, col2 from ...) You've also probably found that the above syntax is not SQL Server friendly.

(And your ID should probably be an auto-incremented ingeter unless you've got another primary key set that fills this role.) Note also that you don't need a "SET" for each column.

Use SET and then give a comma-delimited name=value listing of updates.

I've changed urlencode to htmlentities but that hasn't helped, any ideas ?

From what I've read, this is what you'd call using the update statement extension.

Also, putting stuff into the database, you probably want to add slashes rather than stripping them.

PHP should automatically decode the query string into plain text (removing and other such special characters and converting them back into spaces, quotes, etc.).

Returns a varbinary bit pattern that indicates the columns in a table or view that were inserted or updated.

COLUMNS_UPDATED is used anywhere inside the body of a Transact-SQL INSERT or UPDATE trigger to test whether the trigger should execute certain actions.

I'll just call it using an aliased subselect as that makes more sense in my mind. One last thing before the example that you'll want to pay close attention to.
