C# : DBConnection.Open() timeout is too long.

- by leo

Hi, I'm trying to connect to a server that the user inputs. When the server doesn't exist, I'd like to give a quick feedback to the end-user so he can correct what he's typed. Is there any way to test if a server exists before trying to connect ? Thanks

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;} }

Complex LINQ paging algorithm

- by sharepointmonkey

We have a list of projects that may or may not have a collection of subprojects. Our report needs to contain all the projects except those that are the parent project of a subproject. I need to page this into pages of, say, 25 rows. But if subprojects appear on that page then ALL the subprojects of that project must appear on the same page. So more than 25 items may appear if necessary. I've got as far as var pagedProjects = db.Projects.Where(x => !x.SubProjects.Any()).Skip( (pageNo -1) * pageSize).Take(pageSize); Obviously, this fails the second part of the requirements. As a further pain in the arse, I need to have a pager control on the report. So I'll need to be able to calculate the total number of pages. I could loop through the whole table of projects but the performance will suffer. Can anybody come up with a paged solution? EDIT - I should probably mention that SubProjects joins back onto Projects via a selfreferencing foreign key so the whole lot comes back as an IQueryable<Project>.

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

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)

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.

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?

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.

mysql statement with nested SELECT - how to improve performance

How to have multiple tables with multiple joins

- by williamsdb

I have three tables that I need to join together and get a combination of results. I have tried using left/right joins but they don't give the desired results. For example: Table 1 - STAFF id name 1 John 2 Fred Table 2 - STAFFMOBILERIGHTS id staffid mobilerightsid rights --this table is empty-- Table 3 - MOBILERIGHTS id rightname 1 Login 2 View and what I need is this as the result... id name id staffid mobilerightsid rights id rightname 1 John null null null null 1 login 1 John null null null null 2 View 2 Fred null null null null 1 login 2 Fred null null null null 2 View I have tried the following : SELECT * FROM STAFFMOBILERIGHTS SMR RIGHT JOIN STAFF STA ON STA.STAFFID = SMR.STAFFID RIGHT JOIN MOBILERIGHTS MRI ON MRI.ID = SMR.MOBILERIGHTSID But this only returns two rows as follows: id name id staffid mobilerightsid rights id rightname null null null null null null 1 login null null null null null null 2 View Can what I am trying to achieve be done and if so how?

oracle query with inconsistent results

- by Spencer Stejskal

Im having a very strange problem, i have a complicated view that returns incorrect data when i query on a particular column. heres an example: select empname, has_garnishment from timecard_v2 where empname = 'Testerson, Testy'; this returns the single result 'Testerson, Testy', 'N' however, if i use the query: select empname, has_garnishment from timecard_v2 where empname = 'Testerson, Testy' and has_garnishment = 'Y'; this returns the single result 'Testerson, Testy', 'Y' The second query should return a subset of the first query, but it returns a different answer. I have dissected the view and determined that this section of the view definition is where the problem arises(Note, I removed all of the select clause except the parts of interests for clarity, in the full query all joined tables are required): SELECT e.fullname empname , NVL2(ded.has_garn, 'Y', 'N') has_garnishment FROM timecard tc , orderdetail od , orderassign oa , employee e , employee3 e3 , customer10 c10 , order_misc om, (SELECT COUNT(*) has_garn, v_ssn FROM deductions WHERE yymmdd_stop = 0 OR (LENGTH(yymmdd_stop) = 7 AND to_date(SUBSTR(yymmdd_stop, 2), 'YYMMDD') sysdate) GROUP BY v_ssn ) ded WHERE oa.lrn(+) = tc.lrn_order AND om.lrn(+) = od.lrn AND od.orderno = oa.orderno AND e.ssn = tc.ssn AND c10.custno = tc.custno AND e.lrn = e3.lrn AND e.ssn = ded.v_ssn(+) One thing of note about the definition of the 'ded' subquery. The v_ssn field is a virtual field on the deductions table. I am not a DBA im a software developer but we recently lost our DBA and the new one is still getting up to speed so im trying to debug this issue. That being said, please explain things a little more thoroughly then you would for a fellow oracle expert. thanks

ibatis/Oracle - SELECT query inside INSERT is failing

Hi, I'm trying to do an Insert operation using iBatis. INSERT INTO SCHEMA.TABLE (FIELD1, FIELD2, FIELD3) VALUES (#field1#, (SELECT ANOTHER_FIELD FROM SCHEMA.TABLE WHERE FIELD4= #field2#), #field2#) The inner select query always fails and returns NULL. But if I substitute #field2# with the actual value only in the inner query, it works fine. Why is iBatis not substituting fieldvalues in the innerqueries? Any ideas?

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).

MySQL - display rows of names and addresses grouped by name, where name occures more than once

- by Stoob

I have two tables, "name" and "address". I would like to list the last_name and joined address.street_address of all last_name in table "name" that occur more than once in table "name". The two tables are joined on the column "name_id". The desired output would appear like so: 213 | smith | 123 bluebird | 14 | smith | 456 first ave | 718 | smith | 12 san antonia st. | 244 | jones | 78 third ave # 45 | 98 | jones | 18177 toronto place | Note that if the last_name "abernathy" appears only once in table "name", then "abernathy" should not be included in the result. This is what I came up with so far: SELECT name.name_id, name.last_name, address.street_address, count(*) FROM `name` JOIN `address` ON name.name_id = address.name_id GROUP BY `last_name` HAVING count(*) > 1 However, this produces only one row per last name. I'd like all the last names listed. I know I am missing something simple. Any help is appreciated, thanks!

MySQL - Finding time overlaps

- by Jude

Hi, I have 2 tables in the database with the following attributes: Booking ======= booking_id booking_start booking_end resource_booked =============== booking_id resource_id The second table is an associative entity between "Booking" and "Resource" (i.e., 1 booking can contain many resources). Attributes booking_start and booking_end are timestamps with date and time in it. May I know how I might be able to find out for each resource_id (resource_booked) if the date/time overlaps or clashes with other bookings of similar resource_id? I was doodling the answer on paper, pictorially, to see if it might help me visualize how I could solve this and I got this: Joining the 2 tables (Booking, Booked_resource) into one table with the 4 attributes needed. Follow the answer suggested here : http://stackoverflow.com/questions/689458/find-overlapping-date-time-rows-within-one-table I did step 1 but step 2 is leaving me baffled! I would really appreciate any help on this! Thanks!
