  • Should i really use integer primary IDs [sql]

    - by arthurprs
    For example, i always generate an auto-increment field for the users table, but i also specifies an UNIQUE index on their usernames. There is situations that i first need to get the userId for a given username and then execute the desired query. Or use a JOIN in the desired query. It's 2 trips to the database or a JOIN vs. a varchar index The above is just an example There is a real performance benefit on INT over small VARCHAR indexes? Thanks in advance!

  • SQL - table alias scope.

    - by Support - multilanguage SO
    I've just learned ( yesterday ) to use "exists" instead of "in". BAD select * from table where nameid in ( select nameid from othertable where otherdesc = 'SomeDesc' ) GOOD select * from table t where exists ( select nameid from othertable o where t.nameid = o.nameid and otherdesc = 'SomeDesc' ) And I have some questions about this: 1) The explanation as I understood was: "The reason why this is better is because only the matching values will be returned instead of building a massive list of possible results". Does that mean that while the first subquery might return 900 results the second will return only 1 ( yes or no )? 2) In the past I have had the RDBMS complainin: "only the first 1000 rows might be retrieved", this second approach would solve that problem? 3) What is the scope of the alias in the second subquery?... does the alias only lives in the parenthesis? for example select * from table t where exists ( select nameid from othertable o where t.nameid = o.nameid and otherdesc = 'SomeDesc' ) AND select nameid from othertable o where t.nameid = o.nameid and otherdesc = 'SomeOtherDesc' ) That is, if I use the same alias ( o for table othertable ) In the second "exist" will it present any problem with the first exists? or are they totally independent? Is this something Oracle only related or it is valid for most RDBMS? Thanks a lot

    - by Jason McCreary
    I am trying to number some rows on a bridge table with a single UPDATE/SELECT statement using a counter variable @row. For example: UPDATE teamrank JOIN (SELECT @row := @row + 1 AS position, name FROM members) USING(teamID, memberID) SET rank = position Is something like this possible or do I need to create a cursor? If it helps, I am using MySQL 5.

  • Can I set ignore_dup_key on for a primary key?

    - by Mr. Flibble
    I have a two-column primary key on a table. I have attempted to alter it to set the ignore_dup_key to on with this command: ALTER INDEX PK_mypk on MyTable SET (IGNORE_DUP_KEY = ON); But I get this error: Cannot use index option ignore_dup_key to alter index 'PK_mypk' as it enforces a primary or unique constraint. How else should I set IGNORE_DUP_KEY to on?

  • Arabic SQL query (on Oracle DB) returns empty result

    - by unprecedented
    I have this query (that runs on Oracle 10g database): SELECT ge.*, ge.concept AS glossarypivot FROM s_glossary_entries ge WHERE (ge.glossaryid = '161' OR ge.sourceglossaryid = '161') AND (ge.approved != 0 OR ge.userid = 361) AND concept = '?' ORDER BY ge.concept The query must display all words that begin with the arabic letter "?" but unfortunately, it returns empty result .. However, if I run the same query on the same database which runs on MYSQL, it works well and displays the correct result .. What should I do in order to get this query working the right way on oracle 10 database? P.S. the oracle database character set is : "AL32UTF8" thank you so much in advance

  • Select records by comparing subsets

    - by devnull
    Given two tables (the rows in each table are distinct): 1) x | y z 2) x | y z ------- --- ------- --- 1 | a a 1 | a a 1 | b b 1 | b b 2 | a 1 | c 2 | b 2 | a 2 | c 2 | b 2 | c Is there a way to select the values in the x column of the first table for which all the values in the y column (for that x) are found in the z column of the second table? In case 1), expected result is 1. If c is added to the second table then the expected result is 2. In case 2), expected result is no record since neither of the subsets in the first table matches the subset in the second table. If c is added to the second table then the expected result is 1, 2. I've tried using except and intersect to compare subsets of first table with the second table, which works fine, but it takes too long on the intersect part and I can't figure out why (the first table has about 10.000 records and the second has around 10). EDIT: I've updated the question to provide an extra scenario.

  • Incorrect value for UNIQUE_CONSTRAINT_NAME in REFERENTIAL_CONSTRAINTS

    - by van
    I am listing all FK constraints for a given table using INFORMATION_SCHEMA set of views with the following query: SELECT X.UNIQUE_CONSTRAINT_NAME, "C".*, "X".* FROM "INFORMATION_SCHEMA"."KEY_COLUMN_USAGE" AS "C" INNER JOIN "INFORMATION_SCHEMA"."REFERENTIAL_CONSTRAINTS" AS "X" ON "C"."CONSTRAINT_NAME" = "X"."CONSTRAINT_NAME" AND "C"."TABLE_NAME" = 'MY_TABLE' AND "C"."TABLE_SCHEMA" = 'MY_SCHEMA' Everything works perfectly well, but for one particular constraint the value of UNIQUE_CONSTRAINT_NAME column is wrong, and I need it in order to find additional information from the referenced Column. Basically, for most of the rows the UNIQUE_CONSTRAINT_NAME contains the name of the unique constraint (or PK) in the referenced table, but for one particular FK it is the name of some other unique constraint. I dropped and re-created the FK - did not help. My assumption is that the meta-data is somehow screwed. Is there a way to rebuild the meta data so that the INFORMATION_SCHEMA views would actually show the correct data?

  • Trigger on database using a web application and a winform application

    - by Michael
    Hello all, Situation: I have a web application which shows errors and where you can accept those error messages. I also have a service, which checks errors from a system and sets the error messages in the database. When I accept an error in the web application, i would like the service to know which error message has been accepted, so that it can do some other actions. My guess is that this could be done through some sort of trigger, but i can't figure out how. Can anyone help me with this?

  • Question on SQL Grouping

    - by Lijo
    Hi Team, I am trying to achieve the following without using sub query. For a funding, I would like to select the latest Letter created date and the ‘earliest worklist created since letter created’ date for a funding. FundingId Leter (1, 1/1/2009 )(1, 5/5/2009) (1, 8/8/2009) (2, 3/3/2009) FundingId WorkList (1, 5/5/2009 ) (1, 9/9/2009) (1, 10/10/2009) (2, 2/2/2009) Expected Result - FundingId Leter WorkList (1, 8/8/2009, 9/9/2009) I wrote a query as follows. It has a bug. It will omit those FundingId for which the minimum WorkList date is less than latest Letter date (even though it has another worklist with greater than letter created date). CREATE TABLE #Funding( [Funding_ID] [int] IDENTITY(1,1) NOT NULL, [Funding_No] [int] NOT NULL, CONSTRAINT [PK_Center_Center_ID] PRIMARY KEY NONCLUSTERED ([Funding_ID] ASC) ) ON [PRIMARY] CREATE TABLE #Letter( [Letter_ID] [int] IDENTITY(1,1) NOT NULL, [Funding_ID] [int] NOT NULL, [CreatedDt] [SMALLDATETIME], CONSTRAINT [PK_Letter_Letter_ID] PRIMARY KEY NONCLUSTERED ([Letter_ID] ASC) ) ON [PRIMARY] CREATE TABLE #WorkList( [WorkList_ID] [int] IDENTITY(1,1) NOT NULL, [Funding_ID] [int] NOT NULL, [CreatedDt] [SMALLDATETIME], CONSTRAINT [PK_WorkList_WorkList_ID] PRIMARY KEY NONCLUSTERED ([WorkList_ID] ASC) ) ON [PRIMARY] SELECT F.Funding_ID, Funding_No, MAX (L.CreatedDt), MIN(W.CreatedDt) FROM #Funding F INNER JOIN #Letter L ON L.Funding_ID = F.Funding_ID LEFT OUTER JOIN #WorkList W ON W.Funding_ID = F.Funding_ID GROUP BY F.Funding_ID,Funding_No HAVING MIN(W.CreatedDt) MAX (L.CreatedDt) How can I write a correct query without using subquery?

  • SQL Profiles showing high activity

    - by Wong Chi
    I am running my application locally -- ie. No external traffic and very low number of queries, fully under my control. I see tons of 'Audit Login' and 'Audit Logout' events. What are these and where are they actually stored (ie. Where is this audit log)? Are these a hint of a problem with connections, because I have only a simple connection string within my app and thought that connections would remain active throughout the operation of my app (ie. a single login at launch, and then a single logout when terminating).

  • Unexpected behaviour of Order by clause(SQL SERVER 2005)

    - by Newbie
    I have a table which looks like Col1 col2 col3 col4 col5 1 5 1 4 6 1 4 0 3 7 0 1 5 6 3 1 8 2 1 5 4 3 2 1 4 The script is declare @t table(col1 int, col2 int, col3 int,col4 int,col5 int) insert into @t select 1,5,1,4,6 union all select 1,4,0,3,7 union all select 0,1,5,6,3 union all select 1,8,2,1,5 union all select 4,3,2,1,4 If I do a sorting (ascending), the output is Col1 col2 col3 col4 col5 0 1 5 6 3 1 4 0 3 7 1 5 1 4 6 1 8 2 1 5 4 3 2 1 4 The query is Select * from @t order by col1,col2,col3,col4,col5 But as can be seen that the sorting output is wrong (col2 to col5). Why so and how to overcome this? Thanks in advance

  • Query Execution Plan - When is the Where clause executed?

    - by Alex
    I have a query like this (created by LINQ): SELECT [t0].[Id], [t0].[CreationDate], [t0].[CreatorId] FROM [dbo].[DataFTS]('test', 100) AS [t0] WHERE [t0].[CreatorId] = 1 ORDER BY [t0].[RANK] DataFTS is a full-text search table valued function. The query execution plan looks like this: SELECT (0%) - Sort (23%) - Nested Loops (Inner Join) (1%) - Sort (Top N Sort) (25%) - Stream Aggregate (0%) - Stream Aggregate (0%) - Compute Scalar (0%) - Table Valued Function (FullTextMatch) (13%) | | - Clustered Index Seek (38%) Does this mean that the WHERE clause ([CreatorId] = 1) is executed prior to the TVF ( full text search) or after the full text search? Thank you.
