When I insert a row into a table with 1000+ entries, and attempt to return the row ID (be it from an autoincrement trigger/seq, or from setting the value manually in the insert statement), I get a truncated value:
$db = OCILogon(DATABASE_LOGIN, DATABASE_PASSWORD, DATABASE_NAME);
$mysqldate = date('Y/m/d G:i:s');
$db_vid_id = 748;

On my website you can search 'ads' or 'classifieds'. There are different categories.
Would the searches be faster with multiple tables, one for each category, or wouldn't it matter?
We are talking about around 500 thousand ads.
If it won't slow down the search, please explain yourself so that I understand why it won't, because it seem...

I have a question about why some SQL (running on SQL Server 2005) is behaving the way it is. Specifically, I made a change to reduce lock contention during an update and it seems to be working in cases I didn't think it would.
Original code:
We had an update statement like this, that was being applied to a table with more than 3,000,0...
I am trying to pull data from SQL, and then write it to a text file. This does that, to an extent, but it only pulls 1 from the table, which reads test:test<br> on the text file.

I would like to ask for opinion on making aggregate data by concatenating strings. If I have a column aggregate but I want to concatenate then in an aggregate column, which is faster in terms of performance? Doing one SQL then just aggregating then in the CODE. Or selecting the main data then querying one at a time.
For Example:
