Select Last N Records Matching A Query.
I am trying to select the last n records in a database which conform to criteria selected by a user. I gather that there is no "BOTTOM" equivalent to the "SELECT TOP" command. I've tried "SELECT... ORDER BY... LIMIT X,Y" but MySQL doesn't seem to take a second parameter for the LIMIT statement. Is there any way round this?

Selecting Non Matching Records
How do I go about selecting records from two tables that do not match? example: I have two tables (Table1 and Table2) linked by field1. Table1 will have records added right away where as Table2 will get its records written at a later date. Thus having it in some cases where Table2 will not have a matching record for Table1. What I want to do is generate a list of those items in Table1 that do not have a record written in Table2 as yet.
Get Count Of Matching Records
I have two tables, that I am trying to match up rows and count the number of times first_name AND last_name in table A match first_name AND last_name in table B. What is the best way to do this without creating a mess of queries and code?
Select Not Matching Date Range
I'm looking to write a query which returns a date range result that does not match any date range in the database. Example. id date_from date_to 1 2007-10-10 2007-10-11 2 2007-10-12 2007-10-13 Query returns 2007-10-11 or something along those lines. Is it possible at all?
SELECT Conditional... Matching NULL Rows
I am trying to use a SELECT query to retrieve records from a table that have a certain row set to NULL. However when I try a query like the one below... it is not returning any records, eventhough there are thousands of records that have NULL in the 'row1' row. Example query: PHP $query = "SELECT * FROM table WHERE row1=NULL ORDER BY date DESC";
Matching SQL And Database Query
If I open up phpMyAdmin, click on a database named Gypsy, then click on the SQL tab and paste in the following: GRANT ALL PRIVILEGES ON Gypsy.* TO 'James_Bond'@'localhost' IDENTIFIED BY î‘' FLUSH PRIVILEGES; I know it's at least partially working because I see James_Bond listed among the users when I click on "Privileges" - and I don't see James_Bond listed for any other database. But when I try the following database connection... PHP $link = mysql_connect ("localhost" , "James_Bond", "007") or die(mysql_error()); mysql_select_db ("Gypsy", $link) or die(mysql_error()); I get this error message: Quote: Warning: mysql_connect() [function.mysql-connect]: Access denied for user 'James_Bond'@'localhost' (using password: YES) in /Users/MyName/Sites/Geobop/index.php on line 194 Access denied for user 'James_Bond'@'localhost' (using password: YES)
Need Help With Matching A Range Of Character In A Query
The following query (modified from original to make it easier for you to read) select all of the clients whose fisrt initial of their last name equals a specified character ($lastInitial). It works fine for characters A-Z but I need to know what to set $lastInitial to for it to select clients last names that start with a different character than A-Z such as a number or some kind of punctuation. select * from Clients where left(lastName,1) = $lastInitial order by lastName ASC
How To Select Records?

Select All Records
I have a structure like this: A table (authors) that consists of authors names, ages, and an authorid A table (books) that consists of books names, year published, and a bookid A table (aTob) that consists of authorid and bookid, to match book to author I want to write a select statement that selects all authors and all books they've written, if any. So my best guess is: SELECT authors.name, authors.age, books.name, books.year from authors, books, aTob. But this doesn't work...sems to draw SQL into an infinite operation. The result I'm looking for is a row for each author and book...so some authors will be listed several times if they've written several books...BUT, I also want authors who haven't written any books...The end goal is to have a view in which I can do some statistical things, such as find the average year of publication for each author.
Select Records
I am needing to select records where a field has the current date. I figured that this would work: SELECT * FROM table WHERE DATE(datetimefield) = DATE(NOW()) But that doesnt seem to work. In PHP i receive the following error: 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 '(datetimefield) = DATE(NOW()) ORDER BY datetimefield' at line 1,I have tried with a conjuction of MONTH and DAY, but it always seems to hang on the DAY part of it. Whats up with it?
Select Records
i'm quite a newbie in using MySQL so this question should be an easy-answer one. I've got a db with about 20 tables in it containing various data about architecture projects like name, description, dimensions, year, etc.. Each table contains a specific kind of project but every table has the same structure. I want to select the latest project inserted considering every table (for example latest 10 project between all the tables). I tried with this but doesnt work: SELECT * FROM pro_pianificazione, pro_master, pro_grandi, pro_residenza, pro_terziario, pro_attivita, pro_allestimenti, pro_arti ORDER BY 'id' DESC LIMIT $primo, $per_page Of course the vairables of LIMIT instance are prevoiusly set in the code.
SELECT Records
I have two MySQL tables as follows:A 'wine' table that contains about 50 wines & has fields such as wine_id, name, origin, vintage etcA 'wine_venue' table that lists venues and the wines that each venue does NOT offer. It has 2 fields venue_id and wine_id I want to select all the wines that a specific venue DOES offer. (BTW most venues offer all the wines in the wine table) I have tried the following select statement, but it does not give the result I want!Code: SELECT * FROM wine, wine_venue WHERE wine.wine_id != wine_venue.wine_id AND wine_venue.venue_id = 23

I need to know if it is possible select records from a database table on a remote server and if so what is the command syntax? I'm picturing something along the lines of SELECT * FROM <server address>:<database>.<table> but that does not work.
Select Surrounding Records
I am trying to find a way to select 2 rows before and two rows after a known row. For example, I have a table with an id and a datetime field. Given row with an id of 70, how can I select the two rows that would preceed it, and the two that would follow it, when the table is sorted on the datetime field? I have been looking around, but can't seem to find a way to this.
HOW TO: Select Only The Last 2 Records In A Table.
I'm not very good in mySQL but am trying to modify a script. It has to do with a log table. I want to retrieve the last 2 log records (if any) and if the last log entries are the same as my current (to be) entry, simply update the time in the last entry. But if not, simply insert the new entry. My question is how to select the last two entries from the log table? CREATE TABLE broadcast_log ( id mediumint(8) unsigned NOT NULL auto_increment, time varchar(20) NOT NULL, entry varchar(255) NOT NULL, PRIMARY KEY (id) );

Select Records That Are A Group
I have a table like this: ITEMID CODE 1 1 1 2 1 3 2 1 2 3 2 4 3 1 3 2 4 3 where every item is a set of codes. For example, ItemID 1 = (1,2,3) ItemID 2 = (1,3,4) ItemID 3 = (1,2) ItemID 4 = (3) How can I know if an item exists? For example, if (1,2,3) exists or if (1,2) exists? I'm working with a MySQL Database, and VB.Net application.
Select Records By Date
I got a form where the date is being plugged into the database on items that are marked as sold. I want all records to show up until 5 days after being posted as sold. So for example: If I posted a item as sold on Oct 5th, after Oct 10th the record wouldnt be shown again.
Select Doesn't Show Some Records
This problem is driving me crazy. I've got a table with about 200 records in it. It contains a list of domains. When I do a select * from table it works shows all records. But when I do a select * from table where url="http://www.xxxxxx.com/blahblah" it shows most records but it doesn't show certain ones. At something like record 150 to 160 select * from table where url="http://www.xxxxxx.com/blahblah" doesn't work. So on about 10 records the select doesn't work it just returns 0 records. This is really confusing me because it's strange i've made certain the characters are exactly the same as the record i'm searching for(copy & paste as well) but it just shows 0 records.
Best Way To Select Records WITHOUT Relationship In Another Table?
I have a stock table and a stock_category_r table which is a relationship table between stock items (products) and stock categories (M:M relationship) I need to select stock that is uncategorised. I.e Items that have not been related to ANY categories. I was using this query with a subquery: SELECT s.ID, s.code, s.name FROM `stock` s WHERE s.ID NOT IN (SELECT stockID FROM stock_category_r) Just wondering if this was the most effecient way to find stock records that have no corresponding relationship in stock_catgegory_r ? Do sub queries effect performance much? My tables for this app have very few rows, but I'm interested in the best-practice theory The table structure: CREATE TABLE `stock` ( `ID` smallint(5) unsigned NOT NULL auto_increment, `code` varchar(16) NOT NULL default '', `name` varchar(40) NOT NULL default '', `description` mediumtext NOT NULL, `image` varchar(35) NOT NULL default '', PRIMARY KEY (`ID`), UNIQUE KEY `name` (`name`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1; CREATE TABLE `stock_category_r` ( `stockID` smallint(5) unsigned NOT NULL default Ɔ', `categoryID` tinyint(3) unsigned NOT NULL default Ɔ', PRIMARY KEY (`stockID`,`categoryID`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1;
Select Records In A Range Of Values
I have a figure that a user inputs into a php script for how many people an apartment sleeps. What I want to do is select all properties in a database where this is so. Ok, easy enough for now. What I also need to do is to select apartments that may sleep 1 or 2 people more as well. So, for example, if a person asks for apartments that sleep 3 people, it should return all apertments that sleep 3 and 4 people (already got this working), but if the person asks for an aprtment that sleeps 6 people, it should give all apartments that sleep 6,7 and 8 people and if they ask for an apartment that sleeps 10 people then it should return all apartments that have more than 10 in teh sleeps field.
SELECT Date Records Between Two Given Dates.
Let's say i have a job posting site and a user wants to see the jobs posted between dates.... how would i do that? here's how a table would look like(sample): table: Jobs fields: JobID JobStatus DatePosted DateToDeactivate and when i build the query i would make it something like this: "Select * from Jobs Where JobID = '123' and ( DatePosted BETWEEN 2003-05-08 12:14:37 AND 2004-06-08 12:14:37)" i know that this does not work! how can i do this.
Select Unique Records From A Join?
I have two tables, both tables contain a matching JobID. Some records in the job table are not present in the joblocation table. I need to Select only those records. I thought I could just do a left join on the two tables with a not equal to where clause? SELECT job.JobLocation1, job.City, job.Province, job.SiteName1, job.Code, job.JobID, joblocation.JobID FROM soileng.joblocation joblocation LEFT OUTER JOIN soileng.job job ON joblocation.JobID = job.JobID WHERE job.JobID != joblocation.JobID limit 100 Any ideas on how to get this to work?

SELECT records that only occur one time. I have a table with an ID field. I want to SELECT the records where the ID field only has one occurrence. If it appears in two or more rows I do not want to SELECT it.
Limit On Select Produces Records Out Of Order
I have a Java applet that displays descriptions (from an sql table) in a text area. The latest description is shown on load-up with max(time) ok, and there is a button to step through them in reverse order from latest to earliest. I have a problem with the following query: SELECT idescription FROM descriptions where unit = 'A' and iname = 'plate' order by 'time' limit "+nextrecord+",1 This query is executed on a java button press. The variable 'nextrecord' has already been set to 1 (to get the second latest, i.e. 'very useful item') and then 1 is added to it each time the button is pressed to get the next previous one. But the resulting order is squiffy, e.g. when applyed to the following table Code:
Select / Count Not Showing Records ... Permissions?
I imported 600,000 records from SQL Server 2005 to mySQL. I know they are in there -- I just can't see them! When I do a SELECT, it processes for a while, and then returns nothing. Same with a count, it sits there processing, and then returns a '0' However when I do the same on a table I know has no rows, it definitely comes back right away. I'm logged in as root. Do I need to assign myself some permissions to see these records? And the count numbers?
Select Where Multiple Joined Records Match
I'm trying to figure out how to select all the records in one table which have multiple specified records in a second table. Here's a simplified version of my problem. I have two tables, resources and goals. resources table: ID TITLE 1 civil war women 2 bunnies on the plain 3 North Carolina and WWII 4 geodesic domes goals table: ID RESOURCE_ID GRADE SUBJECT 1 1 1 English 2 1 1 Soc 3 1 2 English 4 2 1 English 5 2 3 Soc 6 3 2 English 7 4 1 English Now, how do I select all the resources which have 1st and 2nd grade English goals? If I just do: Select * from resources, goals where ((resources.ID = goals.RESOURCE_ID) and (SUBJECT="English") and ((GRADE="1") and (GRADE="2"))); I'll get no results, since no record of the joined set will have more than one grade. I can't just put 'or' between the Grade conditions; that would give resources 1, 2, 3, and 4, when only 1 really should match. My real problem is slightly more complex, as the 'goals' table also contains an additional field which might be searched on. I'm thinking it's time for me to go into the deep end of SQL (MySQL, actually), and my old O'Reilly MySQL & mSQL book isn't doing the trick.
Join 2 Tables And Select Only Most Recent Records
I have been wrestling with a way to select only the most recent records for a group of clients without using a subselect. I have two tables: cdp_clients and cdp_level_records related by 'admitid'. For each cdp_client there are multiple cdp_level_records, each with a different 'level_date'. I want to select only the most recent cdp_level_record for each client in cdp_clients.
Deleting Records Upon Query... (!?!)
Sorry for the confusing thread title. Here's what I am trying to do... Read the last six added records for a particular criteria, and delete the rest. Now consider I have around 1000 unique "criteria" and this query is executed a few times a day for each unique... should I delete it on each read or put it in a cron job and schedule it for every night. Here's a sample MySQL syntax for my selectquery: SELECT * FROM table1 WHERE field1 = sometext ORDER BY some_time_field ASC LIMIT 0,6 So the questions, again, are:Can I join this SELECT query with a DELETE, and delete all field1s with "sometext" which were not selected by the query?If I can't, how would I do it with a seperate DELETE query? i.e. Leave the last six records for field1 = sometext and delete the rest?Do I really need to order by some_time_field? Or does MySQL have an internal schema to sort records by their "internal" creation date?
Query Help Looping Through Records
The below Query loops through two tables in mysql and outputs all records where a match_date in a reports table (re) is equal to a match_date in a fixtures table (f).

Query Cannot Retrieves All The Records
I've got this problem, this query is used to create a combo wich display all months where at least a news is been submited (a kind of hostory menù), the fact is that it can display max the months wich correspond to the 107 record submited. The query: select date_format(data,"%b/%Y")as textMonth, month(data)as month,dayofmonth(data)as day,year(data)as year from archivio where category = "Rassegna Stampa" group by month Just to be shure I've also tried the query above on mysql browser, and the result is the same. Can you tell me if there's a kind of limit?
Query And Non Existent Records
I have a mysql table texts which keeps textlines in different languages. columns: textId, languageCode, textline The application adds records for specific languages as: textId 1 languageCode: EN textline: "Username" another record could be: textId 1 languageCode: DE textline "Anwendername" Now at a certain pojnt in the app I have to check whether for a specific textId there are textline filled in for specific languageCode. For example: Is there a textline for records with textIds 120, 124 and 134. And are these records present for EN and FR (French). I can query as: Select count(*) from texts where textline != '' and textId in (120,124,134); But what when the records are there in ENglish and German but not in French? Any ideas how to solve this?
Total Like Records Query
Ime probably missing the boat here so please be patient. I am trying to create a query to display the total number of records with the same parent name.

I think its supposed to look something like: Select sum(Eddings) $total From books

Update A Set Of Records In One Single Query
My records contain a position, from 1 to n. This position is not the primary key. In normal conditions, the position of this records should be as follows: 1, 2, 3, 4, 5, 6, 7, 8, 9 . etc... One of my utitities is meant to check the consistency of the table - one of the things it has to do is scan the table as follows: SELECT position FROM employe_records WHERE employe_id = ? ORDER BY position From the result of this query I verify each entry (JDBC) one by one, looking for inconsistancies. In a for() loop I look at the value of position and check that they start from 1 and are incremented by one for each record. At the first inconsistency I come accross I want to run a query to update the records so it is consistant again - it is something like this: UPDATE employe_records SET position = updatedValue FROM employe_records WHERE employe_id = ? ORDER BY position This is not valid query of course - my question is what should my query look like?! How can I make 'updatedValue' incremented by one automatically so each of the records are updated from 1 to n.
