We are processing spatial data from another source to display in our GIS environment. The data is a set of multi lines. The gtype is 2006. A typical geometry looks like:
Now, this is not an actual multiline... it's just encoded as a multi line, but if you look at the coordinates you'll see that the end point of the first line is the same as the beginning of the second line (105094.84, 195084.96).
SELECT field1, COUNT(x) AS COUNT FROM my_table GROUP BY field1;
For field1 I want to get a count, but if field1 is like 'ABC%' then I want to combine all of those.
So if I have the following: ABC1 | 5 ABC2 | 10 XYZ1 | 3
I want results like this: ABC | 15 XYZ1 | 3
I've tried using some case statements like
SELECT CASE WHEN field1 LIKE 'ABC%' THEN 'ABC' ELSE field1 END AS field1, COUNT(x) AS COUNT FROM my_table GROUP BY CASE WHEN field1 LIKE 'ABC%' THEN 'ABC' ELSE field1 END;
but this just gives me ABC | 5 ABC | 10 XYZ1 | 3
How can I combine record 1 and 2 from the last record set example above?
i have a given pl/sql program that first deletes records out of a table and afterwards inserts new rows. now for example 2 rows out of 10 have a foreign constraint and can not be deleted that easily anymore. so i delete the ones i am able to (with the where not exists clause).
now i want to update the records who have a foreign key constraint and the rest with a regular insert. how would i do this the easiest way. i thought i could use insert with a where clause!!
ive got two select statements which fetches data from different tables. I need to join the two result set . is it possible to do it from sql. Heres the query.
1)
SELECT COUNT(CASE WHEN (INTERACTION_TYPE= 'EmailED' AND CONTACT_PARTY=1) THEN 1 END)CUSTOMER_EMAIL, COUNT(CASE WHEN INTERACTION_TYPE= 'EmailED' AND CONTACT_PARTY=2 THEN 1 END)OTHER_EMAIL,
[Code]....
2)
SELECT SUM (CHEQUE_TOTAL) CHEQUE_TOTAL FROM RI_CHEQUE_VOUCHER_REFUND refund INNER JOIN CH_CASE case ON (case.id = refund.id) INNER JOIN EVA_ENTITY_DEFINITION ed ON (ed.name= 'ChequeRefundCaseED') WHERE case.creation_time<= SYSDATE AND case.creation_time>= SYSDATE-7
Again I need to combine the resultset.So the result would look like
Updated to Add: In a last ditch search, I found my answer with ROWNUM <= 1 in the Where clause. It works and I can go from there with what I want to do.
I have a website that pulls similar information from multiple queries using a Union-based query. I want to only pull 1 record from one section, two from another, and 5 from the third. I've so far found LIMIT but haven't been able to get it to work in that way. Is it possible to limit each query in the union as I am looking to do?
The query is:
SELECTc.priority, c.startDate, p.headline, p.newsID, p.kicker, p.webPath, p.makePopup, p.thumbnail, p.shortDesc, p.storyType, d.filePath FROM (so_news p LEFT OUTER JOIN so_news_deptLevel c ON p.newsID = c.newsID) LEFT OUTER JOIN so_departments d ON d.deptID = c.deptID WHERE p.storyType = 'alert' AND c.display = 'yes' AND c.startDate <= sysDate AND c.endDate >= sysDate UNION All SELECTc.priority, c.startDate, p.headline, p.newsID, p.kicker, p.webPath, p.makePopup, p.thumbnail, p.shortDesc, p.storyType, d.filePath
(CASE WHEN DATEa=DATEb THEN 0 WHEN DATEa> DATEb THEN NETWORKDAYS(DATEb, DATEa) WHEN DATEa < DATEb THEN NETWORKDAYS(DATEa, DATEb) WHEN STATUS='PENDING' THEN NULL ELSE NULL END) AS RESULTa,
Now what I need to be able to do is place those results in buckets, similar to this:
(CASE WHEN RESULTa < 0 THEN '<0' WHEN RESULTa between -1 AND 6 THEN '<=5' WHEN RESULTa >5 THEN '>5' ELSE '' END) AS BUCKETa
I understand that I can't call an alias from a previous case expresson to get these desired results and how I could combine the two statements to get the desired bucket.
I tried writing a decode statement but it doesn't work as expected. The data I'm working has 4 different brand names with an associated code. I tried using decode to get the 4 brands to be on one line like this: Description, Inventory_Item, Product_Line, Product_Type, Brand_1, Brand_2, Brand_3, Brand_4..I still get 4 lines with the Brands displayed like a stair steps.
What do I have to do to get the data on one line? My code is as follows:
Begin str := '...' .... f1 := utl_file.Fopen('EXT_REP_DIR',b,'W',32767); utl_file.Put(f1,str);
Loop .... utl_file.Put(f1,str); End Loop; utl_file.Fclose(f1); End
There would be around 100000 records and I want everything in 1 line(i.e no line breaks). I'm getting error ORA-29285, WRITE_ERROR...By using PUT_LINE, the size of the file is for 10000 records is 3035542. But, I can not use PUT_LINE as this will put NEW_LINE at end of line.
My query is suppose to capture the student's number, date of birth, and number of students which that students mentors. I am suppose to show only the 5 oldest students
SELECT s.std_num, s.birth_date, COUNT(s2.mentor_num) From Student s left outer join Student s2 on s2.mentor_num=s.std_num GROUP BY s.std_num, s.birth_date ORDER BY s.birth_date ASC;
This function works but the problem is in displaying the five records because whenever I apply the rownum<=5 function the counter returns incorrect results. I tried writing another query to fix it but I could not dispay the counter anymore
SELECT ROWNUM as SENIOR, s.std_num, s.birth_date, COUNT(s2.mentor_num) FROM (SELECT s1.std_num, s1.birth_date, COUNT (e2.super_id) From Student s left outer join Student s2 on s2.mentor_num=s1.std_num GROUP BY s1.std_num, s1.birth_date ORDER BY s1.birth_date ASC) S WHERE row_num<=5;
This code only works if I remove the count in the first line but I need to display the number in my result.
I'm working on my database homework, and I came across an error that I cannot seem to fix. I'm getting a missing right parenthesis error on line 7, but I seem to have all my parenthesis, endless I'm overlooking one.
I am running Oracle 9 and using sql loader to import text file into table. Can sql loader skips the record which blank line or carriage return? Do I need to set up with options?
I have some Oracle Databases and sometimes for me is easier to access to the databases with SQLPLUS instead SQLDEVELOPER or TOAD.
But i can't reach to a good configuration of command line prompt to do queries against the database, normaly if it returns a lot o rows and columns it is unreadable.
