  • 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

  • DB2 CASE Statement

    - by gamerzfuse
    I need to somehow use the CASE syntax (which is beyond me) to affect the database results based on criteria. I have a bunch of royalties in 0.# form (royalty) I have a title ID # (title_id) and I need to show the new increase in royalties so that I can use the data. IF: they have a current royalty of 0.0 - 0.1 = 10% raise IF: they have 0.11 - 0.15 = 20% raise IF: royalty >= 0.16 = 20% raise Any help would be much appreciated. create table royalites ( title_id char(6), lorange integer, hirange integer, royalty decimal(5,2));

  • 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

  • Select from table and function

    - by David Oneill
    I have a function that returns a table. The returned table contains (among other things) a store_id. I can get the store_id for a particular transaction_id and city_id as follows: select store_id from table(f_get_store(city_id, transaction_id)); I have another table that contains a list of transactions (which includes transaction_id and city_id). I want a query that returns store_id, city_id, transaction_id for every entry in the transaction table. My first guess was: select f_get_store(city_id, transaction_id), city_id, transaction_id from table; (simplified away the unimportant details) However, this yields an "ORA-00932: inconsistent datatypes" error. How do I need to structure this query? (I'm using Oracle)

  • Using Multiple Foreign Keys to the same table in LINQ

    - by Graeme
    I have a table Users and a table Items In the Items table, I have fields such as ModifiedBy CreatedBy AssignedTo which all have a userId integer. The database is set up to have these as foreign keys back to the Users table. When using LINQToSQL, the relationships which are automatically built from the dbml end up giving me names like User, User1 and User2 e.g. myItem.User1.Name or myItem.User2.Name Obviously this isn't very readable and I'd like it be along the lines of myItem.CreatedByUser.Name or myItem.ModifiedByUser.Name etc I could change the names of the relationships but that means I have to redo that every time I change the db schema and refresh the dbml. Is there any way round this?

  • Modeling a Generic Relationship (expressed in C#) in a Database

    - by StevenH
    This is most likely one for all you sexy DBAs out there: How would I effieciently model a relational database whereby I have a field in an "Event" table which defines a "SportType"? This "SportsType" field can hold a link to different sports tables E.g. "FootballEvent", "RubgyEvent", "CricketEvent" and "F1 Event". Each of these Sports tables have different fields specific to that sport. My goal is to be able to genericly add sports types in the future as required, yet hold sport specific event data (fields) as part of my Event Entity. Is it possible to use an ORM such as NHibernate / Entity framework / DataObjects.NET which would reflect such a relationship? I have thrown together a quick C# example to express my intent at a higher level: public class Event<T> where T : new() { public T Fields { get; set; } public Event() { EventType = new T(); } } public class FootballEvent { public Team CompetitorA { get; set; } public Team CompetitorB { get; set; } } public class TennisEvent { public Player CompetitorA { get; set; } public Player CompetitorB { get; set; } } public class F1RacingEvent { public List<Player> Drivers { get; set; } public List<Team> Teams { get; set; } } public class Team { public IEnumerable<Player> Squad { get; set; } } public class Player { public string Name { get; set; } public DateTime DOB { get; set;} }

    - 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

  • ERD-CLASS design

    - by Mahesh
    Hello guyz,i am new to daatbase and class diagram.I just get scenarios from internet and try to develop ERD and Class Diagram for them.But the following scenario has caused me some problems, and i am not sure about my design. "Whenever an employee fills leave application form, the leave application should be appeared for approval to his/her team leader. Team Leader has the option to change the date of requested leave and to approve or reject the leave. Employee also has the option to change date of previously unapproved leaves or to cancel any of unapproved leave. In case of team leader, he can approve his own leaves. Management should be able to create categories of leaves like (Casual, Sick, Planned work, etc) and should be able to adjust the days allocated to each type of leave". I have identified these as entities for ERD 1) Employee(I think i dont need to make entity for Technical lead,since he is an employee) 2) LeaveHistory 3) LeaveCategory Plz correct me if the system need more classes or entities

  • 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).

  • How to move from untyped DataSets to POCO\LINQ2SQL in legacy application

    - by artvolk
    Good day! I've a legacy application where data access layer consists of classes where queries are done using SqlConnection/SqlCommand and results are passed to upper layers wrapped in untyped DataSets/DataTable. Now I'm working on integrating this application into newer one where written in ASP.NET MVC 2 where LINQ2SQL is used for data access. I don't want to rewrite fancy logic of generating complex queries that are passed to SqlConnection/SqlCommand in LINQ2SQL (and don't have permission to do this), but I'd like to have result of these queries as strong-typed objects collection instead of untyped DataSets/DataTable. The basic idea is to wrap old data access code in a nice-looking from ASP.NET MVC "Model". What is the fast\easy way of doing this?

  • 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?

  • Put stored procedure result set into a table-- any shortcuts besides INSERT INTO...EXEC?

    - by larryq
    Hi everyone, I'm creating a temp table that's the result of a stored procedure's result set. Right now I'm using the create table statement, followed by insert into....exec. It gets the job done but I was curious if there are other ways of going about this? I wish it were possible to run a select into, with the stored procedure's result set serving the role of the select statement, so that I wouldn't have to write a create statement beforehand (so that if the stored proc's columns change, there wouldn't be any modifications needed.) If there are other ways to go about this that might fit my needs better I'd love to hear about them. Thanks very much.

  • 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?

  • 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.

  • 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

  • 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.
