Update Multiple Rows
I have about 20 rows that need to updated together and would rather not have 20 seperate update lines but am not sure what else to do. At the moment it looks something like this: UPDATE movies SET mon='10pm', tues='10pm', wed='11pm' WHERE movie_id='19'... UPDATE movies SET mon='9pm', tues='11pm', wed='4pm' WHERE movie_id='37'... UPDATE movies SET mon='8am', tues='1pm', wed='5pm' WHERE movie_id='19'... There is no logical order to the movie_id's they are selected from the movies table using specific criteria.

Multiple Update Of 21 Rows
I have a database table which holds price ranges for various classes of hire car and various hire periods. There are 7 different hire classes and 3 different hire periods. 21 records in total. Heres an example of what the table contains: ID......HIRE PERIOD.....HIRE GROUP....PRICE 1..........14.....................a...............25.00 2..........28.....................c...............15.00 The rows are shown in an editable form, which is basically a grid of text fields. I need to figure out the most efficient way of updating all the records when the grid is edited. Do I need to perform 21 individual updates? as I'm worried that this will be too cumbersome when there are multiple users. I thought of one way which involves having a hidden field for each row, called 1,2,3 etc, each with a value of eg. 14,a,25.00 as a comma seperated list. Then I split the post values into arrays and perform various updates. Seems a bit clunky though,

Update Multiple Rows Using Arrays
I have an array that I need to put into an existing db column using a perl foreach loop. I can do this using an INSERT statement but the script will be run every day and the source array will be changing as it is based on directory contents so I need to UPDATE vs. INSERT With the INSERT statment the script places each array element on a new row of the db as it should but when I try to use an UPDATE statement, I get a single array element written over and over on each row of the db.

Update Multiple Rows Within One Table
I have a Dynamically created formfield. Tgis field shows the attached devices off a selected device (for instance you have a pc and in the formfields it shows two attached monitors). The monitors however are in the same database table. (with an other device_id ofcourse). The page with the pc info is shown by using the device_id in the URL. What I want to do is update some fields in this table for the pc but also for the attached devices.... When I do it like this: UPDATE dev SET .... etc. WHERE device_id IN ('#FORM.koppel_2#') It selects both device id's like this: WHERE dev_volgnr IN ('602,603') This doesn't work! However in this example the table should be updated for the devices with device_id 602 and 603. Is this possible? How would I do that?

Can't Update Multiple Rows Via PHP, But Works In PhpMyAdmin
My php script will update 1 row fine, but fails on 2. However, the exact same query works when pasted into phpMyAdmin. THIS QUERY WORKS BOTH IN MY PHP AND PHPMYADMIN: $sql = "update table set color='red' where id='1';"; $sql_do = mysql_query($sql); THIS QUERY WORKS ONLY IN PHPMYADMIN: $sql = "update table set color='red' where id='1'; update table set color='green' where id='2';"; $sql_do = mysql_query($sql); I know the second query is correct, because when I copy it from my php code and paste it into phpMyAdmin, it works. But only the first query, with 1 row update, works from my php code.

The Most Efficient Manner To Update Multiple Rows
I have a table that holds information about people The table is quite large (300,000 rows) I need to write code that update many of the rows in the table Here is what I need to do Two of the fields that I store about each person are: location and country The location is some free text which the user can type in, while the country is the ISO country code, like "US", "ES" and so on I need go over all the records in the database, and for those that have a non-empty location field, to extract the value and to try to guess what country the user is from and to update the Country field accordingly My problem is that I might find that most of the records need updating, and this might lead to 100,00+ update statements I cannot use LOAD DATA as this is product database Is there a way to update multiple rows (each with a different value and condition in a single query?

Update All Rows In A Column
I'm a complete newbie but I'm trying to do something that I would think would be easy. In my table I have a column LICLEVEL with values of Club, Expert and Elite. I need to tack on "USA Cycling - " in front of that value, so that if the current data is "Elite" after the update it will say "USA Cycling - Elite". With 800 records to update, I'm hoping there's a fairly easy way to achieve this with SQL (or PHP).

Import A Csv To Update Only Certain Rows Of Data?
I have an existing mysql table and a csv. I want to import the csv into the table, but it is at a different sort order. There are too many records to sort my csv by hand to match. There is a common 'cd_code' field that both have. Is it possible to import a csv to the table so that each row of the csv is inserted in the correct row of the table, based on the common 'cd_code' field? For example, if I sorted by cd_code asc, it would match the csv, but how to I import the csv into a particular sort?

Update Script, But Check If The Value Is The Same On Other Rows
I have a nice user script. In a particular section there is the ability to edit the users on the databse. What I am concerned about is that people may edit the username or email and find its the same username or email that another user has, this can screw up the login system especially two usernames being the same. So is it possible to make it so that if the email/username is the same in another row to give an error, Please note that the input fields for their email and username are already filled in so if they dont come to edit it them they will still output there original username/address.

MySQL Update Speed With 10K+ Of Rows
I Have table called `users` which have 10K+ rows. Each user have a fields called `gold` and `level`. Now each user should get "pow(1.25, level)*100" gold per/hour and it should divide so that users will get 1 gold per time unit. example: user level is 7 and he should get 1.25^7 * 100 gold = 476 gold per hour (1 gold every 7.5 seconds). Now I have a problem. I can't update all users at once every second because it would create too much load for server (mysql load was 100% if I did it). Even if I would do this update in every 7 seconds, it will be too much load for the server. maybe we can determine user gold amount so: user gold = user gold + (seconds_after_last_update/3600); and do update every prime hour? but what happens the when user wants to spend this gold? My mysql-updateing daemon is running in infinite loop doing 1 action every second.

Update Multiple Fields With 'OR'
Is there a better way to do this (more efficient). I have up to 200 items to update per query, the id's are not sequential. Using up 200 (well 199) OR's in a single query doesnt strike me as being the best way to do this. All the fields get set to the same value. # Example UPDATE table SET value=value WHERE id=11 or id=23 or id=31 or id=74 or id=56 or id=96; # Up to 200 fields Or am I stuck with this query?

Multiple Update By Multiple Users
I'm looking at producing an application that will allow multiple users to order multiple items/ parts from what would effectively be an online store. These users could be ordering several hundred items/ parts at a time, each item/ part ordered representing one box or several hundred. Each part record will require the "total stock" to be down dated and each unit will require updated to show it as having been picked (plus other info). I'm looking at programming this in php 4.3 or php 5 using a current version of mysql. Looking around etc. I believe there are various options options open to me : 1 Create a pick list in a database table and have a "pick" routine pick the stock. This would ensure that the actual pick could only be carried out by a single process and the result of the pick request could be emailed to the user. This approach would provide the user with a very fast, responsive acceptance of an order request (but not real time - albeit almost). 2 Use Table Locks - This I understand may be the fastest but potentially could leave users with apparently hung screens, eg. if three picks were issued each taking 10 secs, then pick 3 would not start until the first two picks completed (20 secs). 3 Record Locks - I'm concerned that doing this would increase the time taken to pick the stock. But if the times were not excessive this would provide the user with an immediate "real time" response.

Update Numerous Rows In A Single Query
Let's say I have 6 rows in my MySQL table ID RANK ============= 1 1 2 2 3 3 4 4 5 5 6 6 I want to delete ID #3, that's ok, BUT I want to downgrade all the rows that has a RANK value higher than him (3). So my table would look like this afterwards; ID RANK ============= 1 1 2 2 4 3 5 4 6 5 I want to be able to update a field within the query, something like this $deleted_rank=3; //the rank number that got deleted mysql_query = UPDATE tablename SET rank='rank--' WHERE rank>'$deleted_rank' the field RANK is an INT I know the rank-- thing doesn't work, but I want to know how I can achieve this in a single query, I don't want to do a WHILE on this.

If I use update query, it will update John's rows but there is no rows to update? There are only rows to add and delete at this time. I don't want to delete all records of John every time John enters the data, because a user can potentially have a lot of rows in the table.

How To Update All Fields With A Multiple Of The Field Value?
Is there a MySQL command to replace all the values of a field with the field's original value that's had a mathematical formula applied to it? Basically, I want to divide the field's original value in half, then add 40% more. The formula would be y=x/2+.2x where y is the new value and x is the original value. I know I could write a PHP script that would select each field's value, apply the formula, then update the new value, but it'd be cool if there's a MySQL built-in function to do this.

UPDATE Multiple Tables Difficulties
I've been creating a stock update system that needs to be integrated with an existing database. To update the stock I need 2 tables updated in the same query (unless there is better way). In one table, items_ordered, holds every single product that has been sold and has a field StockUpdated which holds a 1 or 0 depending on whether they have been stock counted already. This will stop future queries counting stock that has already been counted. i.e. the query will look and update each record that has a 0. So far the query is able to update this table successfully.....

UPDATE Large Number Of Rows With CASE Is Very Slow

I need to update the entire table with this query. The problem is the query runs extremely slowly, taking 4.6529 seconds to run. I realize the index is not the most efficient, but is it the main culprit?

Update One Table With Data From Another That Has Multiple Returns
I have a query that works but it takes extraordinary amounts of time to run and I'm sure there's got to be a better way. I haven't touched sql in many years and I just can't remember the proper way to do this. Table 1 has a column that I need to fill from table 2. Table 2 has multiples of the requested data. There are about 303 records in table2 that meet the >0 criteria but only 44 distinct values that I need to retrieve. col1 in both tables is the matching index. What I have so far is: update table1 a set a.col2 = (select b.col2 from table2 b where a.col1=b.col1 and b.col2>0 group by b.col1) I also tried limit 1 instead of group by but there was no difference in execution time (which is about 5 updates in 10 minutes!)
