I have the following case
I have the following csv file format example:
Year;Ligue1;Ligue2;Ligue3
2017;Manchester;Burnley;Doncaster
2016;Chelsea;Aston Villa;Leeds
2015;Arsenal;Newcastle;Sheffield
What I would like to create so far is a table/view with rows just for each year and each Ligue.
For instance : Year : 2017 ; Ligue : League 1 ; Team : Manchester
My idea is the following.
To bulk the CSV file into the database : Bulk into ...
Once the data is loaded I would iterate through all the records from first column (Ligue1 ) until the last column (Ligue 3) and insert these records into a specific view depending on the league classification.
For instance i will create the following view:
View Football with just 3 columns : Year , League, Winner
Insert into Football (Year, League = always the name of the Column (League 1, League 2 or League 3) Team ) where Team is the relevant Winner for the specific year.
Final Result Example:
Year;League;Winner
2017;League1;Manchester
2017;League2;Burnley
2017;League3;Doncaster
Would be the idea of bulking the CSV the best approach?
How could I get the results and cases described in the second step? With Counters / Cursors...?

In my database table i have a table name Household member where the column are
Upzila, union , ward, village , para family_head_name , member_name ,
relation_with_family_head, age , maritial_status.
I want to generate a new table with same structure but with new auto-generate column the column name will be HH_ID , Member_id .Below i will provide simple dataset with the new example column of hh_id and hh_membe_id.
For example the Upazila is Cox Bazar Sadar so i will assume the code is 1 and the union is jhiwanja so jhionja code is 03 then if ward is number 1 and village is Boro chara so code is 01 and the para name is asroyon prokolo that code is 02 so the hh_id will be and the member id will be incremental for example if the house hold contain 3 people so for the first member id (hh_member_id) will be then second member id will be .
I have tried so many approch but i faild to generate that id . last time i have tried to generate the id using excel manually but i faild . so would be the best solution to do that in postgreSQL database .

So I'm trying to match entries in two databases so in the new table the row is comprised of two words that end in the same ending letter. I'm working with two tables that have one column in each of them, each named word. table 1 contains the following data in order: Dog, High, It, Weeks, while table two contains the data: Bat, Is, Laugh, Sing. I need to select from both of these tables and match the words so that each row is as follows: Dog | Sing, High | Laugh, It | Bat, Weeks | Is
The screenshot is what I have so far for my SQL statement. I'm still early on in learning SQL so any info to help on this would be appreciated.
Recommend reading up on SUBSTR() for more information on why the below code works: https://docs.oracle.com/cd/B28359_01/olap.111/b28126/dml_functions_2101.htm#OLADM679
SELECT
a.word
, b.word
FROM sec1313_words1 a
JOIN sec1313_words2 b
ON SUBSTR(b.word, -1) = SUBSTR(a.word, -1)
ORDER BY a.word
I have an unusual question that seems simple but has me stumped in a SQL Server stored procedure.
I have 2 tables as described below.
tblMaster
ID, CommitDate, SubUser, OrigFileName
Sample data
ID CommitDate SubUser OrigFileName
----------------------------------------
1 2014-10-07 Test1 Test1.pdf
2 2014-10-08 Test2 Test2.pdf
3 2014-10-09 Test3 Test3.pdf
The above table is basically the header table that tracks the committed files. In addition to this, we have a details table with the following structure.
tblIndex
ID, FileID (Linking column to the header row described above), Word
Sample data:
1. 1, 1, Oil
2. 2, 1, oil
3. 3, 2, oil
4. 4, 2, tank
5. 5, 3, tank
The above rows represent the words that we want to search on and if a certain criteria matches return the corresponding filename/header row ID. What I would love to figure out to do is if I do a search for
One word (i.e. "oil"), then the system should respond with all the files that meet the criteria (easiest case and figured out)
If more than one word is searched for (i.e. "oil" and "tank"), then we should only see the second file since it is the only one that has both oil and tank as its key words.
Tried using a LIKE "%oil%" AND LIKE "%tank%" and that resulted in no rows being created since one value can't be both oil and tank.
Tried doing a LIKE "%oil%" OR LIKE "%tank%" but I get files 1, 2, and 3 since the OR is inclusive of all the other rows.
One last thing, I recognize I could just do a search for the first term and then save the results into a temp table and then search for the second term in that second table and I will get what I am looking for. The problem with that is that I don't exactly know how many items will be searched for. I don't want to have to create a structure where I am constantly having to store data into another temp table if someone does a search for 6 "keywords".
Any help/ideas will be much appreciated.
try this ! slightly differing from the previous answer
SELECT distinct FileID,COUNT(distinct t.word) FROM tblIndex t
WHERE t.Word LIKE '%oil%' OR t.Word LIKE '%tank%'
GROUP BY FileID
HAVING COUNT(distinct t.word) > 1
One simple option would be to do something like this :
SELECT FileID
FROM tblIndex t
WHERE t.Word LIKE '%oil%' OR t.Word LIKE '%tank%'
GROUP BY FileID
HAVING COUNT(*) > 1
This assume you do not have duplicate in your tblIndex.
I'm also unsure whether you really need the like or not. According to your sample data you don't, a basic comparison would be way more efficient and would avoid possible collisions.
Let's say we have two tables. The first table has following description:
animal_count: {zoo_name:chararray, counts:()}
The meaning of "zoo_name" fields is obvious. "counts" fields contains counts of each specific animal species. In order to know what exact species a given field in "counts" tuple represents, we use another table:
species_position : {species:chararray, position:int}
Let assume we have following data in "species_position" table:
"tiger", 0
"elephant", 1
"lion", 2
This data means the first field in animal_count.counts is the number of tigers in a given zoo. The second field in that tuple is the number of elephants, and so on. So, if we want to represent that fact that "san diego zoo" has 2 tigers, 4 elephants and no lion, we will have following data in "animal_count" table:
"san diego zoo", (2, 4, 0)
Given this setup, how can I write a query to extract the number of a given species in all zoos? I was hoping for something like:
FOREACH species_position GENERATE species, animal_count.counts.$position;
Of course, the "animal_count.counts.$position" won't work.
Is this possible without resorting to UDF?
I have a question about updating multiple rows with different values in MS Access 2010.
Table 1: Food
ID | Favourite Food
1 | Apple
2 | Orange
3 | Pear
Table 2: New
ID | Favourite Food
1 | Watermelon
3 | Cherries
Right now, it looks deceptively simple to execute them separately (because this is just an example). But how would I execute a whole lot of them at the same time if I had, say, 500 rows to update out of 1000 records.
So what I want to do is to update the "Food" table based on the new values from the "New" table.
Would appreciate if anyone could give me some direction / syntax so that I can test it out on MS Access 2010. If this requires VBA, do provide some samples of how I should carry this out programmatically, not manually statement-by-statement.
Thank you!
ADDENDUM (REAL DATA)
Table: Competitors
Columns: CompetitorNo (PK), FirstName, LastName, Score, Ranking
query: FinalScore
Columns: CompetitorNo, Score, Ranking
Note - this query is a query of another query, which in turn, is a query of another query (could there be a potential problem here? There are at least 4 queries before this FinalScore query is derived. Should I post them?)
In the competitors table, all the columns except "Score" and "Ranking" are filled. We would need to take the values from the FinalScore query and insert them into the relevant competitor columns.
Addendum (Brief Explanation of Query)
Table: Competitors
Columns: CompetitorNo (PK), FirstName, LastName, Score, Ranking
Sample Data: AX1234, Simpson, Danny, <blank initially>, <blank initially>
Table: CompetitionRecord
Columns: EventNo (PK composite), CompetitorNo (PK composite), Timing, Bonus
Sample Data1: E01, AX1234, 14.4, 1
Sample Data2: E01, AB1938, 12.5, 0
Sample Data3: E01, BB1919, 13.0, 2
Event No specifies unique event ID
Timing measures the time taken to run 200 metres. The lesser, the better.
Bonus can be given in 3 values (0 - Disqualified, 1 - Normal, 2 - Exceptional). Competitors with Exceptional are given bonus points (5% off their timing).
Query: FinalScore
Columns: CompetitorNo (PK), Score, Ranking
Score is calculated by wins. For example, in the above event (E01), there are three competitors. The winner of the event is BB1919. Winners get 1 point. Losers don't get any points. Those that are disqualified do not receive any points as well.
This query lists the competitors and their cumulative scores (from a list of many events - E01, E02, E03 etc.) and calculates their ranking in the ranking column everytime the query is executed. (For example, a person who wins the most 200m events would be at the top of this list).
Now, I am required to update the Competitors table with this information. The query is rather complex - with all the grouping, summations, rankings and whatnots. Thus, I had to create multiple queries to achieve the end result.
How about:
UPDATE Food
INNER JOIN [New]
ON Food.ID=New.ID
SET Food.[Favourite Food] = New.[Favourite Food]
