Migrate Only Differing Rows?
Im currently using 'mysqldump' to dump the entire contents of my local database to my remote database.
This was fine, but now the database is huge, so I would like to know if there is a MySQL command/statement that compares the two databases and then only uploads rows that have been updated on the local database.
Is this possible to do? I can do this through PHP in a loop, but this takes ages, and I have a feeling there is a much more efficient way to do it using SQL statements.

Migrate DB From 5.0.51a To 5.1.30
It has a relatively large (17 table) database which is basically a custom made forum. It was made in MySQL 5.0.51a which at that time came as part of the WAMP5 server package for Windows. It has been about a year since I worked on it. Foolishly, I did not keep hold of the WAMP5 package that I used. I have downloaded the new WAMP5 package, which comes with MySQL 5.1.30. At first, the old database was not visible to the new MySQL server version. On the old backup I have, the data was located in C:wampinmysqlmysql5.0.51adataaaron_forum. I have basically moved the aaron_forum directory to the new MySQL data directory at C:wampinmysqlmysql5.1.30data and it is now picked up by the new MySQL server installation... however... it doesn't contain any tables according to my PHP, or indeed to the MySQL server. What is odd, is that it does actually display all 17 tables, but then when I try to open a table, it says that it doesn't exist. Quite interesting. I wanted to know if there is a way to migrate the data from the 5.0.51a generated MySQL server to the new 5.1.30 server?

Migrate 4.1 To 4.0- Possible?
I am running a big Drupal site on Host B, which uses MySql 4.1.19. Host B sucks and I want to move to Host A. Except they are running MySql 4.0.27 How can I get my database to work? I tried using dbase from Host B on Host A and am getting syntax errors, preventing the tables from loading. Quote: MySQL said: Documentation #1064 - You have an error in your SQL syntax. Check the manual that corresponds to your MySQL server version for the right syntax to use near 'DEFAULT CHARSET=latin1 AUTO_INCREMENT=1' at line 7

How Often Is Best To Create New Database, Migrate Data With Shared Hosting?
I have got a web site that I have ben working on since March, 2007. It is a news reporting web site. It is replacing an older web site. I created a new database (it uses the MySQL database) last March when I started working on the new web site. I have migrated all of the news content from the old web site database to the new web site database. I have a shared web hosting. It's my understanding that the hosting service provider fills up one server with databases then starts a new server with databases. For example, the IP for the server that is hosting the current database for the new web site is 10.6.166.5 I just created a new database (the hosting allows you to have ten databases per shared hosting). The IP for the server for the recently created database for the new web site hosting is 10.6.166.92 If the servers are ordered sequentially there have been 87 new servers filled up with databases since last March (i.e. 10.6.166.92 recently created IP minus 10.6.166.5 March, 2007 IP equals 87 servers). The problem with migrating the nine-month old database to the new database is that I have got over a thousand news stories and two thousand pictures stored in the database with the 10.6.166.5 IP address. I would have to copy and paste all of the data into the phpMyAdmin program or write a PHP script that would automate the process. Is there any benefit to migrating the 10.6.166.5 March, 2007 IP database over to the more recently created 10.6.166.92 IP database? Would it be reasonable to expect the more recently created database to perform better over the next 12 to 18 months than the one created nine months ago?

Any Way To Optimize Join To Find Rows Without Conditional Foreign Rows?
I've got a table of keywords that I regularly refresh against a remote search API, and I have another table that gets a row each each time I refresh one of the keywords. I use this table to block multiple processes from stepping on each other and refreshing the same keyword, as well as stat collection. So when I spin up my program, it queries for all the keywords that don't have a request currently in process, and don't have a successful one within the last 15 mins, or whatever the interval is. All was working fine for awhile, but now the keywords_requests table has almost 2 million rows in it and things are bogging down badly. I've got indexes on almost every column in the keywords_requests table, but to no avail. I'm logging slow queries and this one is taking forever, as you can see. What can I do? # Query_time: 20 Lock_time: 0 Rows_sent: 568 Rows_examined: 1826718 .....

Searching For Rows That Depend On Other Rows In Some Fashion
Maybe this is a very stupid question. I'll try anayway. I'm using MySQL 3.23.52 on RedHat 8.0. I have a very big table (several millions of rows). Each entry actually constitute a word in a big text. Among other fields we have an ID for each word which represents the postition in the text. Now I want to search for short phrases. For example "welcome to sweden". This means i want to find all occurences of the word "welcome" with ID x, where we have the word "to" with ID x+1 and the word "sweden" with ID x+2. I've tried doing this recursively with temporary tables - but a find myself hitting a wall as i'm not allowed to refer to 2 different temporary tables in the same query... Resorting to another type of data strucutre, full text index etc.. is unfortunately not an option. We only need this as an add on feature if we can do it. We believe that indexes, data structures etc.. are near optimal as is.

SELECT Rows With Field Different From Previous Rows
I have a table (sens_samples) with mysqlerature sensor samples taken every 5 minutes. Rows are: id (INT), sensor_id (INT), timestamp (DATETIME), mysql(FLOAT) and over_mysql(BOOL). I want to make a query to get ONLY the rows when over_mysql field changed from "previous" row value. I know that database rows are UNORDERED, but ORDER BY can "place" them in a given order. My query may be "syntactically" something like: SELECT timestamp, mysql FROM sens_samples WHERE "PREV_ROW".over_mysql <> over_mysql AND sens_id = 1 ORDER BY id; How can I get it using MySQL?

Selecting Rows While Using Values From These Rows In The Where Clause
I have a table which includes 3 columns: id: just an id name: a name parent: the id of the row which this row is a child of. In my example I want to select the rows with the id 5, it's parent, and the parent's parent. I found a syntax that workes in this case: SELECT `name`,`id` FROM `locations` WHERE `id`='5' or `id`=(SELECT `parent` FROM `locations` WHERE `id`='5') or `id`=(SELECT `parent` FROM `locations` WHERE `id`=(SELECT `parent` FROM `locations` WHERE `id`='5')) However my question now is if this syntax could be shortened while still working, and also if there is a way to allow for rows to be selected that do not have a parent( value 0 in my table) or that only have a parent but no grandparent.

Insert New Rows With Qty Values From Existing Rows
I am trying to make all my products unique in my db. Lets say I have a row with an id, it also has all relevant details about the product and it has a quantity value of 4. What I would like to do is take the entire row and duplicate it by the number of the quantity field. This would result in the same product 4 times instead of one product with qty of 4. Reason, I am going to serialise all the products so that they each have unique barcode from the id field. I will encounter the reverse issue when running an insert statement for inputting new data, i.e. insert a new row for each item depending on its qty value??

My app includes a Poll system built from scratch. Each question will run for one month. the month that the poll will run is kept in 2 columns in my table... runMonth and runYear. What i'm having trouble doing is selecting the rows that don't match both the current runMonth and current runYear. My Table... id.............Question...........runMonth...........runYear 1..............QA...................1......................2007 2..............QB...................2......................2007 3..............QC...................3......................2007 4..............QD...................4......................2007 (current month and year) 5..............QE...................5......................2007 6..............QF...................6......................2007 I can simply get the question for the current month... SELECT * FROM table WHERE runMonth = 4 AND runYear = 2007; but if I try to get all others using SELECT * FROM table WHERE runMonth != 4 AND runYear != 2007 I get an empty result set. As I should because there is nothing there that the runYear != 2007 doesn't knock out. The result set I am looking for is id.............Question...........runMonth...........runYear 1..............QA...................1......................2007 2..............QB...................2......................2007 3..............QC...................3......................2007 *********************(remove runMonth4 and runYear 2007) 5..............QE...................5......................2007 6..............QF...................6......................2007 What am I missing?

Get Best Fit Of Rows
I was wondering if its possible in Mysql to pull out the rows in a table that values add up to a certain number - but making sure the best fit is achieved. For example, the table has 2 columns: record and cost (cost being a decimal field -ignore the £ sign) rec1 £0.50 rec2 £1.50 rec3 £0.25 rec4 £1.00 Lets say I have a cost of £5.00 I want to get the records that fits into £5.00 (having the least amount of records). So the best fit would be: rec2, rec2, rec2, rec1 Is there a way of Mysql returning these 4 rows? Or at least just the 2 rows rec2, rec1?

100 Rows In A Db Better Than 1
you have a db for auto repair shops. One table is called services. It has two columns, one for ID and one for the service title. Now let us say you have 100 services. Now let us say you have a table called shops. That table has typical info about a shop (address, name, tel, etc) and also an id field. As I have been taught if I want to specify which services a shop offers I SHOULD NOT add a column to the shop table called "services" and enter a concatenated list such as - 1, 23, 34, 45, 55 (where each number is a service) but rather I should have a third table with two columns, one for service ID and one for Shop id. Now if a single shop offers 100 services that would be 100 rows. If 10 shops have 100 services that is 1,000 rows. Why is this better than having one more column in the shop table.

It contains only 6 fields: id dtime day weather topic content The program does some searches like displaying few previous days' diaries on the first page, and a content search function. It's not very complicated. Currently the program is aimed to contain five year diaries but I might expand it to more than five.
