  • Update multiple table column values using single query

    - by Dave Jarvis
    How would you update data in multiple tables using a single query? In MySQL it would be: UPDATE party p LEFT JOIN party_name n ON p.party_id = n.party_id LEFT JOIN party_details d ON p.party_id = d.party_id LEFT JOIN incident_participant ip ON ip.party_id = p.party_id LEFT JOIN incident i ON ip.incident_id = i.incident_id SET p.employee_id = NULL, c.em_address = '[email protected]', c.ad_postal = 'x', n.first_name = 'x', n.last_name = 'x' WHERE i.confidential_dt IS NOT NULL What is the equivalent SQL statement using Oracle 11g? (Is ANSI SQL possible?) Thank you!

  • T-SQL Query, combine columns from multiple rows into single column

    - by Shayne
    I have seeen some examples of what I am trying to do using COALESCE and FOR XML (seems like the better solution). I just can't quite get the syntax right. Here is what I have (I will shorten the fields to only the key ones): Table Fields ------ ------------------------------- Requisition ID, Number IssuedPO ID, Number Job ID, Number Job_Activity ID, JobID (fkey) RequisitionItems ID, RequisitionID(fkey), IssuedPOID(fkey), Job_ActivityID (fkey) I need a query that will list ONE Requisition per line with its associated Jobs and IssuedPOs. (The requisition number start with "R-" and the Job Number start with "J-"). Example: R-123 | "PO1; PO2; PO3" | "J-12345; J-6780" Sure thing Adam! Here is a query that returns multiple rows. I have to use outer joins, since not all Requisitions have RequisitionItems that are assigned to Jobs and/or IssuedPOs (in that case their fkey IDs would just be null of course). SELECT DISTINCT Requisition.Number, IssuedPO.Number, Job.Number FROM Requisition INNER JOIN RequisitionItem on RequisitionItem.RequisitionID = Requisition.ID LEFT OUTER JOIN Job_Activity on RequisitionItem.JobActivityID = Job_Activity.ID LEFT OUTER JOIN Job on Job_Activity.JobID = Job.ID LEFT OUTER JOIN IssuedPO on RequisitionItem.IssuedPOID = IssuedPO.ID

  • mysql get table based on common column between two tables

    - by Zentdayn
    while trying to learn sql i came across "Learn SQL The Hard Way" and i started reading it. Everything was going fine then i thought ,as a way to practice, to make something like given example in the book (example consists in 3 tables pet,person,person_pet and the person_pet table 'links' pets to their owners). I made this: report table +----+-------------+ | id | content | +----+-------------+ | 1 | bank robbery| | 2 | invalid | | 3 | cat on tree | +----+-------------+ notes table +-----------+--------------------+ | report_id | content | +-----------+--------------------+ | 1 | they had guns | | 3 | cat was saved | +-----------+--------------------+ wanted result +-----------+--------------------+---------------+ | report_id | report_content | report_notes | +-----------+--------------------+---------------+ | 1 | bank robbery | they had guns | | 2 | invalid | null or '' | | 3 | cat on tree | cat was saved | +-----------+--------------------+---------------+ I tried a few combinations but no success. My first thought was SELECT report.id,report.content AS report_content,note.content AS note_content FROM report,note WHERE report.id = note.report_id but this only returns the ones that have a match (would not return the invalid report). after this i tried adding IF conditions but i just made it worse. My question is, is this something i will figure out after getting past basic sql or can this be done in simple way? Anyway i would appreciate any help, i pretty much lost with this. Thank you. EDIT: i have looked into related questions but havent yet found one that solves my problem. I probably need to look into other statements such as join or something to sort this out.

  • MySQL: SELECT highest column value when WHERE finds similar entries

    - by Ike
    My question is comparable to this one, but not quite the same. I have a database with a huge amount of books, with different editions of some of the same book titles. I'm looking for an SQL statement giving me the highest edition number of each of the titles I'm selecting with a WHERE clause (to find specific book series). Here's what the table looks like: |id|title |edition|year| |--|-------------------------|-------|----| |01|Serie One Title One |1 |2007| |02|Serie One Title One |2 |2008| |03|Serie One Title One |3 |2009| |04|Serie One Title Two |1 |2001| |05|Serie One Title Three |1 |2008| |06|Serie One Title Three |2 |2009| |07|Serie One Title Three |3 |2010| |08|Serie One Title Three |4 |2011| |--|-------------------------|-------|----| The result I'm looking for is this: |id|title |edition|year| |--|-------------------------|-------|----| |03|Serie One Title One |3 |2009| |04|Serie One Title Two |1 |2001| |08|Serie One Title Three |4 |2011| |--|-------------------------|-------|----| The closest I got was using this statement: select id, title, max(edition), max(year) from books where title like "serie one%" group by name; but it returns the highest edition and year and includes the first id it finds: |--|-----------------------|-------|----| |01|Serie One Title One |3 |2009| |04|Serie One Title Two |1 |2001| |05|Serie One Title Three |4 |2011| |--|-----------------------|-------|----| This fancy join also comes close, but doesn't give the right result: select b.id, b.title, b.edition, b.year from books b inner join (select name, max(edition) as maxedition from books group by title) g on b.edition = g.maxedition where b.title like "serie one%" group by title; Using this I'm getting unique titles, but mostly old editions.

    - by user440485
    Hi All, I am working on page(Lesson) has button called "AddToFavorite". when i click on this button lessonID,lessonHeading is added in the Coredata. - (NSFetchedResultsController *)fetchedResultsController { // Set up the fetched results controller if needed. if (fetchedResultsController != nil) { return fetchedResultsController; } // Create the fetch request for the entity.

  • Better ways to print out column names when using cx_Oracle

    - by philipjkim
    Found an example using cx_Oracle, this example shows all the information of Cursor.description. import cx_Oracle from pprint import pprint connection = cx_Oracle.Connection("%s/%s@%s" % (dbuser, dbpasswd, oracle_sid)) cursor = cx_Oracle.Cursor(connection) sql = "SELECT * FROM your_table" cursor.execute(sql) data = cursor.fetchall() print "(name, type_code, display_size, internal_size, precision, scale, null_ok)" pprint(cursor.description) pprint(data) cursor.close() connection.close() What I wanted to see was the list of Cursor.description[0](name), so I changed the code: import cx_Oracle import pprint connection = cx_Oracle.Connection("%s/%s@%s" % (dbuser, dbpasswd, oracle_sid)) cursor = cx_Oracle.Cursor(connection) sql = "SELECT * FROM your_table" cursor.execute(sql) data = cursor.fetchall() col_names = [] for i in range(0, len(cursor.description)): col_names.append(cursor.description[i][0]) pp = pprint.PrettyPrinter(width=1024) pp.pprint(col_names) pp.pprint(data) cursor.close() connection.close() I think there will be better ways to print out the names of columns. Please get me alternatives to the Python beginner. :-)

  • SQLite If Column Exists

    - by Nathan
    I was wondering if there is a nice IF NOT EXISTS for checking columns and indexes in SQLite, or do I need to bring back the entire database schema and validate against that?

  • c# finding matching words in table column using Linq2Sql

    - by David Liddle
    I am trying to use Linq2Sql to return all rows that contain values from a list of strings. The linq2sql class object has a string property that contains words separated by spaces. public class MyObject { public string MyProperty { get; set; } } Example MyProperty values are: MyObject1.MyProperty = "text1 text2 text3 text4" MyObject2.MyProperty = "text2" For example, using a string collection, I pass the below list var list = new List<>() { "text2", "text4" } This would return both items in my example above as they both contain "text2" value. I attempted the following using the below code however, because of my extension method the Linq2Sql cannot be evaluated. public static IQueryable<MyObject> WithProperty(this IQueryable<MyProperty> qry, IList<string> p) { return from t in qry where t.MyProperty.Contains(p, ' ') select t; } I also wrote an extension method public static bool Contains(this string str, IList<string> list, char seperator) { if (String.IsNullOrEmpty(str) || list == null) return false; var splitStr = str.Split(new char[] { seperator }, StringSplitOptions.RemoveEmptyEntries); foreach (string s in splitStr) foreach (string l in list) if (String.Compare(s, l, true) == 0) return true; return false; } Any help or ideas on how I could achieve this?

  • EntityFramework: Access dabase-column using user defined Type

    - by Nils
    I "inherited" an old Database where dates are stored as Int32 values (times too, but dates shall suffice for this example) i.e. 20090101 for Jan. 1st 2009. I can not change the schema of this database because it is still accessed by the old programs. However I want to write a new program using EF as the O/R-M. Now I'd love to have DateTime-Values in my Model. Is there a way to write a custom type and use this as a Type in the EF-Model. Something like a Type "OldDate" with properties: DatabaseValue : Int23 Value : DateTime (specifying the date-part whereas the time-part is always 0:00:00) Is something like this possible with the EF-Model ?

  • How to remove "Standard Error" column from xtable() output of an lm on R/RSweave/LaTeX

    - by Lucas Spangher
    I'm currently doing some data analysis on population data, so reporting the standard errors in the tables of parameter coefficients just doesn't really make statistical sense. I've done a fair bit of searching and can't find any way to customize the xtable output to remove it. Can anyone point me in the right direction? Thanks a lot, I didn't post this lightly; if it's something obvious, I apologize for having wasted time!

  • Dynamic Column lookup with different pages in excel

    - by CinCity
    I have a multi page spread sheet in excel that needs to read information dynamically from columns on other pages and have these values show up on a main page. This is the formula I'm using: =IF(VLOOKUP($B:$B,'CP01'!$B:$BN,3,FALSE)="r","r", IF(VLOOKUP($B:$B,'CP01'!$B:$BN,3,FALSE)="a","a","")) CP01 is a sheet in the excel file and instead of look at the specific sheet I want it to look at all of the sheets in the file. Is there a way to do this as an excel formula or with excel-VBA? Edit: I also tried CP* (* being a wildcard character) and it didn't work. Edit2: Is there a way to match the value where the 'CP' is placed with its a other columns value?

  • SUM of column with Left Outer Join

    - by Matt
    I am trying to get the Count of all records that have at least on person who is authorized on the record. Basically, a Record can have more than one person associated with it. I want to return the count of Total Records, a count of total Authorized Records where at least 1 person is authorized, and a count of total NotAuthorized records where no person associated with record is authorized. It doesn't matter if one person is authorized per Record or if 3 people are authorized for that record, that should add 1 to the Authorized counter. The current query is incrementing Auth and Non auth for each person added per record rather, than one per record. If no people are assigned to the record that should also count towards Not Auth. SELECT Count(DISTINCT Record.RecordID) AS TotalRecords, SUM(CASE WHEN People.PersonLevel = 1 THEN 1 ELSE 0 END) AS Authorized, SUM(CASE WHEN People.PersonLevel <> 1 THEN 1 ELSE 0 END) AS NotAuthorized FROM Record LEFT OUTER JOIN RecordPeople ON Record.RecordID = RecordPeople.RecordID LEFT OUTER JOIN People ON RecordPeople.PersonID = People.PersonID

  • Why MySQL multiple-column index is overpopulated?

    - by actual
    Consider following MySQL table: CREATE TABLE `log` ( `what` enum('add', 'edit', 'remove') CHARACTER SET ascii COLLATE ascii_bin NOT NULL, `with` int(10) unsigned NOT NULL, KEY `with_what` (`with`,`what`) ) ENGINE=InnoDB; INSERT INTO `log` (`what`, `with`) VALUES ('add', 1), ('edit', 1), ('add', 2), ('remove', 2); As I understand, with_what index must have 2 unique entries on its first with level and 3 unique entries in what "subindex". But MySQL reports 4 unique entries for each level. In other words, number of unique elements for each level is always equal to number of rows in log table. Is that a bug, a feature or my misunderstanding?

  • Test the sequentiality of a column with a single SQL query

    - by LauriE
    Hey, I have a table that contains sets of sequential datasets, like that: ID set_ID some_column n 1 'set-1' 'aaaaaaaaaa' 1 2 'set-1' 'bbbbbbbbbb' 2 3 'set-1' 'cccccccccc' 3 4 'set-2' 'dddddddddd' 1 5 'set-2' 'eeeeeeeeee' 2 6 'set-3' 'ffffffffff' 2 7 'set-3' 'gggggggggg' 1 At the end of a transaction that makes several types of modifications to those rows, I would like to ensure that within a single set, all the values of "n" are still sequential (rollback otherwise). They do not need to be in the same order according to the PK, just sequential, like 1-2-3 or 3-1-2, but not like 1-3-4. Due to the fact that there might be thousands of rows within a single set I would prefer to do it in the db to avoid the overhead of fetching the data just for verification after making some small changes. Also there is the issue of concurrency. The way locking in InnoDB (repeatable read) works (as I understand) is that if I have an index on "n" then InnoDB also locks the "gaps" between values. If I combine set_ID and n to a single index, would that eliminate the problem of phantom rows appearing? Looks to me like a common problem. Any brilliant ideas? Thanks! Note: using MySQL + InnoDB
