I have a MySQL DB in which I store data about each user.
I would like to add a list of friends for each user. Should I create a table of friends for each user in the DB or is there a better way?
Is it possible to merge these two mysql queries into one? I want to get NOW() returned to a php variable.

I really haven't found normal example of php file where mysql transactions are being used. Can you show me simple example of that?
And one more question. I've already created a lot of programming and didn't use transaction, maybe I can put any php function or smth to header.php that if one mysql_query fails, then others too?
Thank you.
Hello,
I backed up my db with mysqldump from phpMyAdmin. Using MySQL 5.0.22. Made no changes to database file. Import fails. Found many instances of extra spaces using notepad, but now cannot find any other such extraneous spaces. Error is 1064.
Any suggestions on how to import file properly?
Thanks.
Iam quite new to functions in SQL and I would like to create a function to compare values in a MySQL table against previous and I am not sure how to do this.
For example (iId is the input value)
DECLARE pVal INT(20);
DECLARE val INT(20);
SELECT price INTO pVal FROM products WHERE Id=iId;
SELECT price FROM products;
IF price == pVal THEN
SET val = price;
END IF;
Thanks
I'm changing my dataset in my program. And when my job was finished, I'm connecting to mysql database. I don't want to do this job again, how can I send changings to database like this
mydatadapter.Update(dataset, " table");
I found this code, but I can't run it :S
Why Nibernate HQL can not handle the following query:
from Deal D where (D.ApprovalDate + INTERVAL 1 Year) < current_timestamp() < (D.RenewalDate + INTERVAL -1 Year)
knowing that INTERVAL and YEAR are keywords in MySQL, so this is kind of mixing Sql within Hql (unless Hql can handle date functions like so and I don't know) . The dialect is MySQLDialect
Its perfectly valid to execute this query
SELECT '2005-01-01' + INTERVAL 1 Year;
I want to add 100 entry to users table numbers field, random characters length is 10, all entry should be unique as well. How can i achieve this using MYSQL query code ?

Hi I have a field in mySql table called jobnumber which auto increments with each new entry. What I want to do is when a user views my form, get the value of the next 'jobnumber' . But I want to do this before any entry is made to the table. IE so when a user looks at a form it will display something like 'this is job number 6954'
I have tried $rr = mysql_insert_id() but this only work after I have made an entry
Can anyone help please
thanks
Is it possible to import the attributes of one table, then I put it into another table using a query in mysql?
For example I have table1 with attributes lname, fname, mname
And I want to put those attributes into table2.
Is there any query that could do that? I'm imagining that the table2 has one attribute that could later be dropped so that it will be the same as table1.
I have a classified_id variable which matches one document in a MySql table.
I am currently fetching the information about that one record like this:
SELECT * FROM table WHERE table.classified_id = $classified_id
I wonder if there is a faster approach, for example like this:
SELECT 1 FROM table WHERE table.classified_id = $classified_id
Wont the last one only select 1 record, which is exactly what I need, so that it doesn't have to scan the entire table but instead stops searching for records after 1 is found?
Or am I dreaming this?
Thanks
Hello,
I am trying to insert data into a mysql table from a csv file. I am using the infile sql command, but I am having trouble because the first column of the table is an id that is set as an auto increment field. what do I have to set my first column value to in order to get this to work, or can I do it at all?
Thanks
I am torn between postgreSQL and MySQL but I am forced to install the choosen one on windows. I especially need asp.net membership and i will be installing NHibernate as well.
I have this mysql query:
SELECT *
FROM Customer c
JOIN eHRDemographic ehD ON ehD.CxID = c.CustomerID
JOIN CustPrimaryWeight cpW ON cpW.CxID = c.CustomerID
WHERE c.CustomerID =22703
GROUP BY c.CustomerID
ORDER BY cpW.CustPrimaryWeightID DESC
This doesn't really work correctly as the CustPrimaryWeight table has multiple enteries and it's simply joining the first entry and not the more recent one as the ORDER statement doesn't seem to do anything.
Any ideas?
I've created a salt using; md5(rand(0,10000000)); (there is probably a better way?)
There doesn't seem to be possible to make a text field unique in MYSQL. So how do I check if the salt has already been used for a previous user?
Or should I generate the salt based on the current date/time? as it is impossible for 2 users to register at exactly the same time correct?
I'm running program at apache tomcat server, that should be on permanently, but every morning(the client part isn't accessible at night) i receive error message (in apache tomcat console) that MySQL server is off. So is there any way to prevent this?

If I have a Parent and Child table in MySQL related by a foreign key, is it possible using a SQL statement to move certain rows from Parent and the related rows from Child into archive tables (e.g. Parent_Archive and Child_Archive) in an atomic manner?
