Master List Of Select Rows
I am creating a database as part of a service record for items. When an item is serviced, an entry is added to the database with the item serial number and some other info. That all works great.
I also want to create a master list of all items. If I use the old "SELECT * FROM database WHERE 1" query, it will display all the rows in the database. Is there any way to retrieve the last row for each item number, instead of displaying all rows for all items? It seems I have worked myself into a corner with this table setup. If it can't be accomplished the way I have it set up, is there a better way to structure the table?
I thought about creating another field "type" and have it be either "parent" or "child" and then only display the "parent" rows in the master list. That would involve two queries when updating an item's status (adding a new row and updating the "parent" row for that item), and seems to be less convenient.
This seems like a common application so there has to be another way.

Query For Month Data Based On Occurance Against Master List
I have a query running nicely. Now I'm trying to expand it. It pulls the data from a table based on matching the id with another table and part of the grouping is by month and 2 other criteria. Now I'm trying to get the data pulled by month to pull only the info where the id matches the master file AND the FRANID's pulled are the same for each month. I'm trying to get a comparisson across times, but not every month has all FRANID's, depending on when they were entered and I ony want data that exists with matches over set months, starting for now with 12, perhaps also for 6 and 3 next time. I've simplified what I'm doing above, but it is detailed below.....

Master Master Replication, Truncate Table Fails, Version 5.0.22
I have set up a master master replication link between two databases, prototyping an idea. Anyhow, adding records and deleting works, both get updated, creating and dropping tables works, but truncating tables doesn't work. My main questions are, why doesn't truncate work, and if it doesn't work, what else doesn't work across a master-master replication link?

Backing Up A Circular Master-master Replication Setup
I have a running circular master - master replication running. I want to run a mysqldump on one of the servers but am worried what the impact of running a mysqldump will be on the replication. Will the transactions generated by the mysqldump get put into the binary log file? I see the option --delete-master-logs for mysqldump and am assuming that it deletes the previously inserted log items from the binary log file. If there is someone that can please just give me a little more clarification on how the --delete-master-logs option works.

Getting Rows Multiple By List Query
I have a list of values (constants) that I use to find matching rows in a single table as follows: "select id, name from articles where id in(1,2,3,2,3,2,2)" seems very simple, but my problem is, the query delivers only 3 lines, of course, because the last four numbers are redundant. But my need is, to get a row for each number in the list, wheather it is doubled or not.

How To Find All Rows Where Id Is One Of A Long List Of Ids?
I have a long list of "id" values: id1, id2, id3, etc. I want to find all rows in a table where the id is in the list. In other circumstances, I want to find all rows where the id is NOT in the list. Is there a more concise query that the following? SELECT * FROM table WHERE id=id1 OR id=id2 OR id=id3 OR ... For instance, I can't find a syntax that looks like this: SELECT * FROM table WHERE id IN (id1,id2,id3,...) Also, ... if the list of id values is the result of a previous SELECT query, is there a way to save that result and use it in a subsequent query?

Master / Master Asynchronous Replication
Currently we have a web based application that is mostly reads (4:1 r/w). It is using a single MySQL database server. Is there any way to have two database servers in a master/master configuration such that writes to either database server are replicated to eachother. Basically even though we have a 4:1 ration of read/write the writes happen often enought that when the database goes down the app stops working. I know how to get this working in Oracle (insert big laugh here) but Oracle is cost prohibitive. Any pointers?

Master/Master Replication Problems
I was wondering whether someone could help me. I have inherited set of replicated servers from a guy I used to work with, basic set up is: Master1/Slave2 - Server ID 1 Master2/Slave1 - Server ID 2 When I looked at the logs it looks as though Server ID 2 is well out of step. Having looked at the slave status it appears that that Slave_SQL_Running state is set to No and a particular piece of SQL is causing the problem. Having ran the SQL on the particular server it has now problem at all. Now my understanding of this type of set up is that Server ID 1 writes directly to Server ID 2, then Server ID 1 is in turn replicated to. But for the life in me, I cannot understand why this piece of SQL is causing the problem. Can anyone offer me any ideas on how I can best get to the bottom of this, I'm really struggling with this. There was me thinking replication just worked! Is there an ability to get MySQL to log all queries it is running, so I can get to the bottom of all queries currently being executed?

Select With Multiple Primary Keys Against List Of Values
I have created a method that automatically parses the metadata of a specified table and searches each field to effectively create a database search. The way it currently stands, it only supports tables with a single PK. Basically it returns a string that can be appended to the WHERE clause in a SELECT. i.e. "ID IN (1, 2, 3, 4)" Basically the PK field name and a list of matching PKs from the search. I realized though that this will break if I have a table with multiple primary keys. An elegant solution for this eludes me, and that is what I am asking for input on. Right now I can only think of returning something like : "(ID = 1 AND SSN = '123121234') OR (ID = 2 AND SSN = '432434321') OR ..." This obviously would become a monster if many results were returned. And if I did something like : "ID IN (1, 2) AND SSN IN ('123121234', '432434321')" This will either return false positives or nothing at all ... Is there a better way for me to create this conditional?

Don't Select Rows That Match Both Columns But DO Select Rows That Don't Match Both
I suppose it is because it is 2:30 AM but I'm having a bit of trouble figuring out the SQL I need to write. I am usually pretty good at this. Here's what I'm having trouble with. 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?

Using A Field, Which Is A Comma Separated List, As The List In An IN Comparison Test.
The following query only reads the first character of a comma separated list stored in a field of the records being queried. The varchar field in table d named "display" holds 1,4 The query " select * from d where 4 IN (display) " tests false. If I change the field "display" to 4,1 Then the query tests true. It is either testing only the first character, or is stopping at the comma. I need this to test true if the value is anywhere in the list, what am I doing wrong here?

Trying To Select Rows With Max Date
This is my query: SELECT i_dest,i_rate, price_1, effective_from FROM Rates r ORDER BY i_dest; I have multiple entries for each "i_dest". Every entry does have a unique i_rate (the younger the entry the higher the i_rate since it's the tables primary key with auto-inc). Also every entry does have a unique effective_from datetime value. I would like to select all distinct i_dest definitions having either the highest i_rate value or the highest/youngest datetime in effective_from. I have tried something like this: SELECT i_dest,i_rate, price_1, effective_from FROM Rates r GROUP BY i_dest HAVING MAX(i_rate); Unfortunately this does not work, i.e. it does not result in only the rows with the highest i_rate. If I go like this: SELECT i_dest,max(i_rate), price_1, effective_from FROM Rates r GROUP BY i_dest; then I do see the highest i_rate BUT the price_1 and effective_from entries are those from other rows with a lower i_rate (and same i_dest obviously).

Select With Dummy Rows When Grouping?
If I select from a table and, for example, group by the month or day to determine how much activity there is day to day or month to month, it will only return months and days with a record and leave out any month or day without any records making it apear at a glance that every day or month has activity which forces me or whoever to have to look at the date column and actively look for spots where a day or more elapses without a single row in order to determine when nothing has happened. Is there any select method for grouping on something like a month and to have it output a dummy row for missing days or months without having to write a program that makes an individual select for each day?
