  • Replace into equivalent for postgresql and then autoincrementing an int

    - by Mohamed Ikal Al-Jabir
    Okay no seriously, if a postgresql guru can help out I'm just getting started. Basically what I want is a simple table like such: CREATE TABLE schema.searches ( search_id serial NOT NULL, search_query character varying(255), search_count integer DEFAULT 1, CONSTRAINT pkey_search_id PRIMARY KEY (search_id) ) WITH ( OIDS=FALSE ); I need something like REPLACE INTO for mysql. I don't know if I have to write my own procedure or something? Basically: check if the query already exists if so, just add 1 to the count it not, add it to the db I can do this in my php code but I'd rather all that be done in postgres C engine Thanks for helping

  • How to give weight to full matches over partial matches (PostgreSQL)

    - by kagaku
    I've got a query that takes an input searches for the closet match in zipcode/region/city/metrocode in a location table containing a few tens of thousands of entries (should be nearly every city in the US). The query I'm using is: select metrocode, region, postalcode, region_full, city from dv_location where ( region ilike '%Chicago%' or postalcode ilike '%Chicago%' or city ilike '%Chicago%' or region_full ilike'%Chicago%' ) and metrocode is not null Odd thing is, the results set I'm getting back looks like this: metrocode;region;postalcode;region_full;city 862;CA;95712;California;Chicago Park 862;CA;95712;California;Chicago Park 602;IL;60611;Illinois;Chicago 602;IL;60610;Illinois;Chicago What am I doing wrong? My thinking is that Chicago would have greater weight than Chicago Park since Chicago is an exact match to the term (even though I'm asking for a wildcard match on the term).

  • How to avoid overlapping date ranges when using a grouping clause?

    - by k rey
    I have a situation where I need to find time spans between value changes. I tried a simple group by clause but it eliminates overlapping changes. Consider the following example: create table #items ( code varchar(4) , class varchar(4) , txdate datetime ) insert into #items (code, class, txdate) values ('A', 'C', '2010-01-01'); insert into #items (code, class, txdate) values ('A', 'C', '2010-01-02'); insert into #items (code, class, txdate) values ('A', 'C', '2010-01-03'); insert into #items (code, class, txdate) values ('A', 'D', '2010-01-04'); insert into #items (code, class, txdate) values ('A', 'D', '2010-01-05'); insert into #items (code, class, txdate) values ('A', 'C', '2010-01-06'); insert into #items (code, class, txdate) values ('A', 'C', '2010-01-07'); insert into #items (code, class, txdate) values ('A', 'D', '2010-01-08'); insert into #items (code, class, txdate) values ('A', 'D', '2010-01-09'); select code , class , min(txdate) mindate , max(txdate) maxdate from #items group by code, class This returns the following results (notice the overlapping date ranges): |code|class|mindate |maxdate | ---------------------------------- |A |C |2010-01-01|2010-01-07| |A |D |2010-01-04|2010-01-09| I would like to have the query return the following: |code|class|mindate |maxdate | ---------------------------------- |A |C |2010-01-01|2010-01-03| |A |D |2010-01-04|2010-01-05| |A |C |2010-01-06|2010-01-07| |A |D |2010-01-08|2010-01-09| Any ideas and suggestions?

  • mysql statement with nested SELECT - how to improve performance

    - by ernie
    This statement appears inefficient because only one one out of 10 records are selected and only 1 of 100 entries contain comments. What can I do to improve it ? $query = "SELECT A,B,C, (SELECT COUNT(*) FROM comments WHERE comments.nid = header_file.nid) as my_comment_count FROM header_file Where A = 'admin' " edit: I want header records even if no comments are found.

  • question about frequency of updating access

    - by I__
    i have a table in an access database this access database is used on a regular basis, basically from 9-5 someone else has a copy of this exact table. sometimes records are added, sometimes deleted, and sometimes data within the records is updated. i need to update the access database table with the offsite table every hour or so. what is the best algorithm of updating the data? there are about 5000 records. would it severely lock up the table for a few seconds every hour? i would like to publicly apologize for my rude comment to david fenton

  • How to switch from MSSQL to MySQL for using with Excel pivot

    - by Sim
    Hi all, I have a table that contains sales transaction (~20 mil rows). Previously I used MSSQL and export it to an Excel pivot. Data refresh took 10-15 minutes but still do-able. However, after I migrated to MySQL (using XamppLite & ODBC), it took forever to refresh the data in the Excel pivot. Maybe I didn't optimize the MySQL good enough ? Anyone can share some thoughts 'bout this ? Thanks

  • SSIS 2005 - How to Import a Fixed Width Flat File?

    - by Greg
    I have a flat file that looks something like this: junk I don't care about \n \n columns names\n val1 val2 val3\n val1 val2 val3\n columns names \n val1 val2 val3\n I only care the lines with values. These value lines are all fixed width format and have the same line length. The other junk lines and column names can have any line width. When I try the flat file fixed width option or the ragged right option the preview looks all wrong. Any ideas what the easiest way to get this into SSIS is?

  • Logical operator AND having higher order of precedence than IN

    - by AspOnMyNet
    I’ve read that logical operator AND has higher order of precedence than logical operator IN, but that doesn’t make sense since if that was true, then wouldn’t in the following statement the AND condition got evaluated before the IN condition ( thus before IN operator would be able to check whether Released field equals to any of the values specified within parentheses ? SELECT Song, Released, Rating FROM Songs WHERE Released IN (1967, 1977, 1987) AND SongName = ’WTTJ’ thanx

  • Freebase Query with "JOINS"

    - by codemonkey
    ... Yeah, yeah, I know traditional joins don't exist. I actually like the freebase query methodology in theory, just having a little trouble getting it to actually work for me : ) Anyone have a dumb-simple example of getting Freebase data via MQL that pulls from two different "tables"? In particular, I'm trying to get automotive data... so for example, pulling fields from both /automotive/model_year and /automotive/trim_year. I've read the documentation (for hours actually). There's a distinct possibility that I'm looking right at such an example somewhere and just not seeing it because my OLTP brain just doesn't comprehend what it's seeing. * Note * ... that the two "types" I'm working with above are siblings, not parent/child. Does freebase even allow joining data between sibling nodes... I see examples of queries pulling from parent/child, but not from siblings I don't think (or I've overlooked them).

  • MySQL table data transformation -- how can I dis-aggreate MySQL time data?

    - by lighthouse65
    We are coding for a MySQL data warehousing application that stores descriptive data (User ID, Work ID, Machine ID, Start and End Time columns in the first table below) associated with time and production quantity data (Output and Time columns in the first table below) upon which aggregate (SUM, COUNT, AVG) functions are applied. We now wish to dis-aggregate time data for another type of analysis. Our current data table design: +---------+---------+------------+---------------------+---------------------+--------+------+ | User ID | Work ID | Machine ID | Event Start Time | Event End Time | Output | Time | +---------+---------+------------+---------------------+---------------------+--------+------+ | 080025 | ABC123 | M01 | 2008-01-24 16:19:15 | 2008-01-24 16:34:45 | 2120 | 930 | +---------+---------+------------+---------------------+---------------------+--------+------+ Reprocessing dis-aggregation that we would like to do would be to transform table content based on a granularity of minutes, rather than the current production event ("Event Start Time" and "Event End Time") granularity. The resulting reprocessing of existing table rows would look like: +---------+---------+------------+---------------------+--------+ | User ID | Work ID | Machine ID | Production Minute | Output | +---------+---------+------------+---------------------+--------+ | 080025 | ABC123 | M01 | 2010-01-24 16:19 | 133 | | 080025 | ABC123 | M01 | 2010-01-24 16:20 | 133 | | 080025 | ABC123 | M01 | 2010-01-24 16:21 | 133 | | 080025 | ABC123 | M01 | 2010-01-24 16:22 | 133 | | 080025 | ABC123 | M01 | 2010-01-24 16:23 | 133 | | 080025 | ABC123 | M01 | 2010-01-24 16:24 | 133 | | 080025 | ABC123 | M01 | 2010-01-24 16:25 | 133 | | 080025 | ABC123 | M01 | 2010-01-24 16:26 | 133 | | 080025 | ABC123 | M01 | 2010-01-24 16:27 | 133 | | 080025 | ABC123 | M01 | 2010-01-24 16:28 | 133 | | 080025 | ABC123 | M01 | 2010-01-24 16:29 | 133 | | 080025 | ABC123 | M01 | 2010-01-24 16:30 | 133 | | 080025 | ABC123 | M01 | 2010-01-24 16:31 | 133 | | 080025 | ABC123 | M01 | 2010-01-24 16:22 | 133 | | 080025 | ABC123 | M01 | 2010-01-24 16:33 | 133 | | 080025 | ABC123 | M01 | 2010-01-24 16:34 | 133 | +---------+---------+------------+---------------------+--------+ So the reprocessing would take an existing row of data created at the granularity of production event and modify the granularity to minutes, eliminating redundant (Event End Time, Time) columns while doing so. It assumes a constant rate of production and divides output by the difference in minutes plus one to populate the new table's Output column. I know this can be done in code...but can it be done entirely in a MySQL insert statement (or otherwise entirely in MySQL)? I am thinking of a INSERT ... INTO construction but keep getting stuck. An additional complexity is that there are hundreds of machines to include in the operation so there will be multiple rows (one for each machine) for each minute of the day. Any ideas would be much appreciated. Thanks.

  • Select count / duplicates

    - by mike
    Hello! I have a table with all U.S. zip codes. each row contains the city and state name for the zip code. I'm trying to get a list of cities that show up in multiple states. This wouldn't be a problem if there weren't X amount of zip codes in the same city... So basically, I just want to the city in a state to count as 1 instead of it counting the city/state 7 times because there are 2+ zip codes in that city/state... I'm not really sure how to do this. I know I need to use count but how do I tell the mysql to only count a given city/state combo as 1?

  • Getting an entry before and after a given entry in a Django Queryset

    - by Vernon
    I am creating a simple blog as part of a website and I am getting stuck on something that I am assuming is simple. If I call any blog post, say by it's title, from a queryset, how can I get the entry before and after the post in it's published order. I can iterate over the whole thing, get the position of the entry I have and use that to call the one before and the one after. But that is a long bit of code for something that I am sure I can do more simply. What I want would be something like this: next_post = Posts.object.filter(title=current_title).order_by("-published")[-1] Of course because of the filter, it is not going to work, but just to give you the idea of what I am looking for.

  • Finding the right terminology for a dictionary table

    - by Karl Forner
    My concern is about what I currently call "dictionary tables", that are database tables containing a list of controlled vocabulary. Let's use an example: Suppose you have a table User containing fields: user_id : primary key first_name last_name user_type_id : foreign key to the UserType table and another table UserType with just two fields: user_type_id : primary key name : the name/value of a particular type of user. For instance, the UserType table may contain (1, Administrator), (2, PowerUser), (3, Normal)... My question is: what is the canonical term for a table like UserType, that only contains a list of (dictinct) words. I want to publish some code that help managing this kind of tables, but first I have to name them ! Thanks for your help. Current state of thought: For now I feel Lookup Tables is a good term. It is also used with the same meaning in these posts: http://dbix-class.35028.n2.nabble.com/RFC-Component-for-Lookup-tables-td3504085.html http://tonyandrews.blogspot.de/2004/10/otlt-and-eav-two-big-design-mistakes.html Lookup Tables Best Practices: DB Tables... or Enumerations The only problem is that lookup table is also sometimes used to name a junction table.
