  • Which MySql line is faster:

    - by Camran
    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

  • How can I update a field in a MySQL database table by addition in MySQL database in a single query

    - by undefined
    I have a table that stores a value that will be added to over time. When I want to add to the value I would like to do so in a single query rather than - Get oldValue from database newValue = oldValue + X update row with newValue $query1 = "SELECT value FROM table WHERE id = thisID"; $result1 = mysql_query($query1); while($row=mysql_fetch_array($result)) { $oldValue = $row['value']; } $newValue = $oldValue + x $query1 = "UPDATE table SET value = $newValue WHERE id = thisID"; Can this be done in a single query?

  • ORDERING A MYSQL QUERY WITH JOINS AND GROUPS

    - by Oliver
    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?

  • How do you debug MySQL stored procedures?

    - by Cory House
    My current process for debugging stored procedures is very simple. I create a table called "debug" where I insert variable values from the stored procedure as it runs.

  • Unique text field in MySQL and php

    - by Jonathan
    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?

  • MySQL Limiting a query to one consistent value

    - by Lucas Matos
    My current query returns a table like: +------------+ value1 | .... value1 | .... value2 | .... value3 | .... +------------+ I want: +------------+ value1 | .... value1 | .... +------------+ I want to only receive all rows with the first value. Normally I would do a WHERE clause if I knew that value, and I cannot use a LIMIT because each value has a different number of rows. Right now My query looks like "SELECT u.*, n.something, w.* FROM ... AS u, ... AS n, ... AS w WHERE u.id = n.id AND w.val = n.val AND u.desc LIKE '%GET REQUEST VARIABLE%';" This works great, except I get way too many rows and using PHP to do this ruins code portability and is superfluous. Thanks for reading

  • MySQL using function IN with variable

    - by misanov
    I have problem querying table with variable in IN function. SELECT s.date, (SELECT GROUP_CONCAT(value) FROM value WHERE id_value IN(s.ref_values) ) AS vals FROM stats s ORDER BY s.date DESC LIMIT 1 Where s.ref_values is '12,22,54,15'. I get only one return for first number (12). When I insert that value directly in IN(12,22,54,15) it finds all 4. So, there must be problem with using variable in IN. What am I doing wrong?

    - by Chris Brandsma
    Something strange is going on with NHibernate for me. I can select, and I can insert. But I can't do and update against MySql. Here is my domain class public class UserAccount { public virtual int Id { get; set; } public virtual string UserName { get; set; } public virtual string Password { get; set; } public virtual bool Enabled { get; set; } public virtual string FirstName { get; set; } public virtual string LastName { get; set; } public virtual string Phone { get; set; } public virtual DateTime?
