Latest-date Query
I am trying to get all records that share the most recent "RatesUpdated" datetime value from 1 table. I am doing the below query and I keep getting the following syntax error: "#1111 - Invalid use of group function" SELECT t1.Product, max(t2.RatesUpdated) FROM `lqdp_mortgage_rates` t1, `lqdp_mortgage_rates` t2 WHERE t1.RatesUpdated = max(t2.RatesUpdated) group by max(t2.RatesUpdated)

Latest In Mysql Query?
I want to run a query, to export the 10 most recent rows. There are a few possible ways i can think of to do this. I have an id column that is autoincrement, so i think i could order them in desc, then limit to 10...would it work? Or i also have a date column, so i guess with a little more work i could list by date. Any idea how to do this?

Delete Except Latest 2500 Entries (was "help With Query")
I have a table that holds information on activities. For each activity I store the following: ID, When, Description The ID is the key for the table The When column holds the datetime when the activity was added The table gets filled up pretty quickly. I would like to run a query that will delete ALL the entries except for the 2500 latest ones. The When column should be the one to use when deciding which are the 2500 latest activities Can someone show me the most efficient way of doing this?

Query For Dates
Table Data: ----------- id__name___from_________to_______ ------------------------------------- 1___ABC___2006-10-01___2006-10-31 2___CDE___2006-11-01___2006-11-31 is there a syntax to select both rows at once? i.e. if I query for dates from 2006-10-15 to 2006-11-15, is there a possibility to have the two rows as a result of a single SQL Statement query?

Query Dates
I am trying to find records where my approved date is not NULL and my shipped date is NULL. Using phpMyAdmin the records show cells with italic NULL and others with dates ie. 2006-06-11, so I assume this is formated right. However using this query I get no records. SELECT * FROM records WHERE approved_date != NULL AND shipped_date = NULL I have used phpMyAdmin's search section with every conceivable way and I can't get any proper results.

Query Using Dates
I'm having trouble figuring out how to get two time periods in one query. Basically it's either one month at a time or a full year...So I need to get everything that starts and stops this month, or cases where this month falls between the start and stop dates. I couldn't figure out how to do the between bit, so I settled for calling an expiration date that is not older than this month.I get partially correct results. It's calling the five ads that start on 2006-12-01 and end 2006-12-31, and ignoring the ones that start 2007-01-01 and end 2007-01-31. However, I've got a test ad that starts 2006-01-01 and ends 2006-12-31 that it's ignoring...I think my timeframes are cancelling each other out or something. $sql = "SELECT ad_id, ad_filename,rally,affiliates,past,upcoming,start_date FROM ads WHERE Month(start_date)='$curmonth' AND Year(start_date)='$curyear' OR Month(end_date)>='$curmonth' AND Year(end_date)>='$curyear'ORDER BY rally='y' DESC";

Dates NOT IN Query Confusion
I have a table of properties and a table of dates, each date relates to when a property is BOOKED. I am trying to write a search so that users can find available properties for their desired date range. I have a query that s working, but I think that it might need to change for other variables! Code: SELECT DISTINCT pid FROM properties WHERE pid NOT IN (SELECT pid FROM cal WHERE takendate between '2009-01-20' and '2009-01-29') AND property_publish='Y' AND property_sleeps >='1' cal table stores: pid (property id) takendate In this instance the dates 2009-01-20 -> , 2009-01-23 are TAKEN, however dates from 2009-01-24 -> 2009-01-29 are AVAILABLE. How would I flag it as available if only some of the dates are available? (eg. only hide property if ALL the date range is taken)

Creating A Query Based On Dates
I am trying to write a query (in PHP) which selects from a database all of the items which are in the future.

Converting MS Access Dates To MySQL Dates During LOAD DATA INPUT ?
My insert code is below. The MySQL server is on my local machine and is version 4.1.22. I am exporting from an access table with 6 fields to a mysql table with those 6 plus 5 more fields.

Also, how do I convert currency fields in the load data process?

Query On Any Combo Of 3 Columns
I've been trying unsuccessfully to contruct this query with 'if' statements, using PHP and mySQL. I have originally succeeded with ASP and an MS-SQL version of the same app. I have 3 columns a user can search on, but they can enter text that would apply to any of the three columns. There is a text box for keywords, and two drop lists. The user should be able to enter any number of keywords, which would appear in certain columns. They can also select an option from either, or both drop lists, or neither. My 'if' statements have become very complicated and messy trying to contruct this query, and on one combination of input, they are actually failing. Any suggestions as to how this could be accomplished? And would it be neater / faster via a stored procedure? And with regards to the keywords, would I be able to take multiple keywords from the text box, and search on each of those separatly, instead of the whole string? I have not posted current code, as it is very long and complicated, but can if needed.

Compare Two Date Columns In Mysql Query
I have 2 date columns in my table. One grabs the date that the article was created. The 2nd is user-defined and is used to tell the site when to "auto-archive" the article. I need to compare the two date columns to each other in a query so that I know if there are any current articles that have not been auto-archived. I thought I could use something like: $query = "SELECT * FROM publications where date_full >= auto_archive"; But this doesn't work. Anyone got any ideas?

How Do I Make Rows From Another Table Appear As Columns In Query?
I have a join query (which r937 kindly helped me out with) which joins a table of tracks with a table of albums in a many-to-many relationship. I also have a table called links with a column of URLs called links. There's also a column of link categories called linkTypes which is of type enum with three possibilities - artist, album and track. What I'd really like to do is to add three columns to the result set (if that's the correct term) of the join from above i.e. I'd like to add trackLinks, artistLinks, albumLinks. So I guess my question is: How can I make columns on the fly by using field values from another table? In answer to the first thquestion - why don't you just add the columns to those two tables? The answer is because in the future I will need an undetermined number of each of these columns, e.g. one artistLink column per affiliate - artistLinkItunesUS, artistLinkItunesUK etc. So is this something I can feasibly do without restructuring the database or should I use a couple of queries and try combine the data through PHP? Or perhaps I'm looking at the relationships incorrectly? Having to add columns like that does seem like a one-to-many relationship which I haven't taken care of.

Update String Dates Into Mysql Dates
I've got a table that someone created with varchar fields for month, day, and year. I've added a DATE field to the table, and now I want to combine all three of these strings into one DATE and stick it into the DATE field. Once I've got this done, I can delete those three varchar fields and just have the nice DATE field. Here's the command I've tried in several variations but no luck--syntax errors every time: UPDATE SET OCR_Entry_Date = date_format(str_to_date(concat_ws('-', OCR_MM, OCR_DD , OCR_YYYY) ,"%b-%d-%Y"), "%m-%d-%Y") WHERE OCR_YYYY = '1974' OCR_Entry_Date is a DATE field and the others are the varchar fields. My logic is basically: 1. concatenate the separate field values into a single string 2. convert the string into a date 3. format the date in the way I'd like it in the table

MSSQL Dates -> MySQL Dates Automatically?
We're using data feeds that were originally meant for MS SQL and the dates in the data feed (tab delimited text files) are formated like: Oct 21 2007 In MySQL, the date fields are formatted as datetime fields and when we do an import the dates all come through as 0000-00-00 00:00:00. We're importing using the MySQL "LOAD DATA LOCAL INFILE" command and just dumping the text files right into freshly truncated tables. Is there a way when loading the files to find and replace the dates maybe? Can MySQL convert the dates? I have a shell script downloading an archive and uncompressing, then it runs a PHP script that loops through the files runningt he LOAD DATA command. Any advice would be appreciated... I'm just looking for the easiest (and least server-intensive) way to get the date issue fixed. We've already tried begging the vendor but they're not yet ready to start supporting other date formats (even though their MS SQL db can output a date format friendly to MySQL). Thanks!

List All The Dates Between 2 Given Dates Using SELECT
how I can list all the dates between 2 dates (inclusive) using SELECT sql statement in mysql? I have a member table with the following columns: id int autoincrement name varchar(40) join_date date I want the following output (date, count of members joined on that date): 1 April 2009...... (2 members joined) 2 April 2009...... (0 members joined) 3 April 2009...... (3 members joined) .....so on ...upto 30 April 2009.....(1 members joined) For the above output I need the SQL command that is valid in mysql. Is there anyone who can produce the above result with a single SELECT command. Please don't suggest that is possible using php for loop or creating a mysqlorary table first and then inserting all the dates into it. Then make a join between mysql table and members table using date as GROUP by column etc. etc. I know this is possible using some user variables as I searched through the various SQL tutorial sites. But I am unable to figure out how I can produce a list of all dates between 2 given dates.
