but what if I want also to include another table
for example, can I do this :
SELECT R.Stock_StockID,S.StockName, MAX(R.RequestPrice),
SUM(R.RequestTotal) FROM
Request R, StocksT S WHERE S.StockID=R.Stock_StockID AND
R.RequestType='Offer' AND
R.RequestENDDate=Date(now()) GROUP BY
Hi
The query will work and should.
As of our understanding,
you want to retrieve the sum of the total column for a particular id, with
its max price where the type='offer' and id same for both the tables.
Is it so?
Thanks

I have a table with a SMALLINT column that -- trough a mistake --
contains values like 57, 13 etc. which in fact are 0x57 and 0x13 (i.e.
HEX numbers).
How would I convert
13 (false decimal) to 0x13 (Hex) and from there to 19 (decimal)?
I tried my luck with UNHEX and CAST but I only got 0
Alternatively one could use a TRIGGER that updates the start_yr_mo
whenever start_date is modified but I'm unsure if triggers are present
before 5.1.
Triggers are new in 5.0

This didn't work.
To explain in easy way, let say I have this table
ID, OrderID, Price, Total, Type
1 200 100 20 Offer
2 200 700 40 Offer
3 200 700 30 Offer
4 300 100 60 Offer
5 300 500

You need to look at the GROUP BY clause
If all the columns from a GROUP BY clause
are not indexed or if the columns in the
GROUP BY clause are from different tables,
MySQL will use the temp table.
Please send your query to the MySQL List
and the structure of all tables in the query

Hi
This is my SQL command:
Select cs_documents.str_url FROM logs_2006_11
LEFT Join cs_documents ON int_url_strem = cs_documents.id
where
logs_2006_11.int_bots = 0
And
(
cs_documents.str_url LIKE '%.asp' Or
cs_documents.str_url LIKE '%.php' Or
cs_documents.str_url LIKE '%.html' Or
As for this part of your query
(
cs_documents.str_url LIKE '%.asp' Or
cs_documents.str_url LIKE '%.php' Or
cs_documents.str_url LIKE '%.html' Or
cs_documents.str_url LIKE '%.htm' Or
cs_documents.str_url LIKE '%.jsp' Or
cs_documents.str_url LIKE '%.aspx' Or

Are there any hard and fast rules for this? If someone has already

For example:

Change:

I'm creating a forum in php where users are able to store comments in
a text field (think blog comments). To prevent SQL injection, I'm
using the php function mysql_real_escape_string() on data going into
the text field. Is this really enough to be safe, or should I be doing
more?
