  • Cannot resolve collation conflict in Union select

    - by phenevo
    Hi, I've got tqo queries: First doesn't work: select hotels.TargetCode as TargetCode from hotels union all select DuplicatedObjects.duplicatetargetCode as TargetCode from DuplicatedObjects where DuplicatedObjects.objectType=4 because I get error: Cannot resolve collation conflict for column 1 in SELECT statement. Second works: select hotels.Code from hotels where hotels.targetcode is not null union all select DuplicatedObjects.duplicatetargetCode as Code from DuplicatedObjects where DuplicatedObjects.objectType=4 Structure: Hotels.Code -PK nvarchar(40) Hotels.TargetCode - nvarchar(100) DuplicatedObjects.duplicatetargetCode PK nvarchar(100)

  • insert data into several tables

    - by csetzkorn
    Let us say I have a table (everything is very much simplified): create table OriginalData ( bla char(10) not null ) And I would like to insert its data (set based!) into two tables which model inheritance create table Statements ( Id int IDENTITY NOT NULL, ProposalDateTime DATETIME null ) create table Items ( StatementFk INT not null, ItemName NVARCHAR(255) null, primary key (StatementFk) ) Statements is the parent table and Items is the child table. I have no problem doing this with one row which involves the use of IDENT_CURRENT but I have no idea how to do this set based (i.e. enter several rows into both tables). Thanks. Best wishes, Christian

  • 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

  • Strange LINQ to SQL Behavior

    - by mcass20
    What is wrong with the last query? Is it a bug or am I missing something? This query returns 2 records (correct): query = query.Where(Log => SqlMethods.Like(Log.FormattedMessage, "%<key>Name</key><value>David</value>%")); This query returns 2 records (correct): query = query.Where(Log => SqlMethods.Like(Log.FormattedMessage, "%<key>Name</key><value>%David%</value>%")); This query returns 0 records (correct): query = query.Where(Log => SqlMethods.Like(Log.FormattedMessage, "%<key>Name</key><value>av</value>%")); This query returns 2 records (correct): query = query.Where(Log => SqlMethods.Like(Log.FormattedMessage, "%<key>Name</key><value>%av%</value>%")); This query returns 0 records (correct): query = query.Where(Log => SqlMethods.Like(Log.FormattedMessage, "%<key>Name</key><value>v</value>%")); This query returns 15 records (incorrect, should return 2): query = query.Where(Log => SqlMethods.Like(Log.FormattedMessage, "%<key>Name</key><value>%v%</value>%"));

  • Creating a stored procedure in SQL Server 2008 that will do a "facebook search"

    - by dig
    Hello, I'm trying to implement a facebook search in my system (auto suggest while typing). I've managed to code all the ajax stuff, but I'm not sure how to query the database. I've created a table called People which contains the fields: ID, FirstName, LastName, MiddleName, Email. I've also created a FTS-index on all those fields. I want to create a stored procedure that will get as a parameter the text inserted in the query box and returns the suggestions. For example, When I will write in the textbox the query "Joh Do" It will translate to the query: select * from People where contains(*, '"Joh*"') and contains(*, '"Do*"') Is there a way to do that in stored procedure? P.S I've tried to use the syntax select * from People where contains(*,'"Joh*" and "Do*"') but it didn't returned the expected results, probably because it needs to search the words on different fields. Is there a way to fix that? Thanks.

  • Modeling many-to-one with constraints?

    - by Greg Beech
    I'm attempting to create a database model for movie classifications, where each movie could have a single classification from each of one of multiple rating systems (e.g. BBFC, MPAA). This is the current design, with all implied PKs and FKs: TABLE Movie ( MovieId INT ) TABLE ClassificationSystem ( ClassificationSystemId TINYINT ) TABLE Classification ( ClassificationId INT, ClassificationSystemId TINYINT ) TABLE MovieClassification ( MovieId INT, ClassificationId INT, Advice NVARCHAR(250) -- description of why the classification was given ) The problem is with the MovieClassification table whose constraints would allow multiple classifications from the same system, whereas it should ideally only permit either zero or one classifications from a given system. Is there any reasonable way to restructure this so that a movie having exactly zero or one classifications from any given system is enforced by database constraints, given the following requirements? Do not duplicate information that could be looked up (i.e. duplicating ClassificationSystemId in the MovieClassification table is not a good solution because this could get out of sync with the value in the Classification table) Remain extensible to multiple classification systems (i.e. a new classification system does not require any changes to the table structure)? Note also the Advice column - each mapping of a movie to a classification needs to have a textual description of why that classification was given to that movie. Any design would need to support this.

  • Stored proc executes >30 secs when called from website, but <1 sec when called from ssms

    - by Blootac
    I have a stored procedure that is called by a website to display data. Today the web page has started timing out so I got profiler going and saw the query that was taking too long. I then ran the same query in management studio, under the same user login, and it takes less than a second to return. Is there anything obvious that could be causing this? I can't think of a reason why when ASP calls the stored proc it takes 30 secs but when I call it it's fine. Thanks

  • Looping over some selected values in a stored procedure

    - by macca1
    I'm trying to modify a stored procedure hooked into an ORM tool. I want to add a few more rows based on a loop of some distinct values in a column. Here's the current SP: SELECT GRP = STAT_CD, CODE = REASN_CD FROM dbo.STATUS_TABLE WITH (NOLOCK) Order by STAT_CD, SRT_ORDR For each distinct STAT_CD, I'd also like to insert a REASN_CD of "--" here in the SP. However I'd like to do it before the order by so I can give them negative sort orders so they come in at the top of the list. I'm getting tripped up on how to implement this. Does anyone know how to do this for each unique STAT_CD?

  • Convert Military time to string representation

    - by RRUZ
    I have an column declarated as int (called HourMil) wich store the time in military format. i need convert this values to an formated string (HH:MM) example HourMil = 710 -> must be 07:10 HourMil = 1305 -> must be 13:05 Actually i am using this code (and works ok) for convert the column HourMil to the string representation. SELECT SUBSTRING(LEFT('0',4-LEN(CAST(HourMil AS VARCHAR)))+CAST(HourMil AS VARCHAR),1,2)+':'+SUBSTRING(LEFT('0',4-LEN(CAST(HourMil AS VARCHAR)))+CAST(HourMil AS VARCHAR),3,2) FROM MYTABLE but I think this code can be improved.

  • Reading a part of a alpha numeric string in SQL

    - by novice
    I have a table with one column " otname " table1.otname contains multiple rows of alpha-numeric string resembling the following data sample: 11.10.32.12.U.A.F.3.2.21.249.1 2001.1.1003.8281.A.LE.P.P 2010.1.1003.8261.A.LE.B.B I want to read the fourth number in every string ( part of the string in bold ) and write a query in Oracle 10g to read its description stored in another table. My dilemma is writing the first part of the query.i.e. choosing the fourth number of every string in a table My second query will be something like this: select description_text from table2 where sncode = 8281 -- fourth part of the data sample in every string Many thanks. novice

  • Stored Procedure IDENTITY_INSERT

    - by Jacob
    I'm recently change my data table, I remove column and add a new column that define as identity = True and identity seed = 1, identity increment = 1. When i tried to insert data to this table by STORE PROCEDURE i get this exception: An explicit value for the identity column in table 'AirConditioner' can only be specified when a column list is used and IDENTITY_INSERT is ON. I saw that i need to add this lines: SET IDENTITY_INSERT [dbo].[AirConditioner] ON and finally OFF I added and its still throw an exception... My store procedure is attached as a picture

  • How can I improve my select query for storing large versioned data sets?

    - by Jason Francis
    At work, we build large multi-page web applications, consisting mostly of radio and check boxes. The primary purpose of each application is to gather data, but as users return to a page they have previously visited, we report back to them their previous responses. Worst-case scenario, we might have up to 900 distinct variables and around 1.5 million users. For several reasons, it makes sense to use an insert-only approach to storing the data (as opposed to update-in-place) so that we can capture historical data about repeated interactions with variables. The net result is that we might have several responses per user per variable. Our table to collect the responses looks something like this: CREATE TABLE [dbo].[results]( [id] [bigint] IDENTITY(1,1) NOT NULL, [userid] [int] NULL, [variable] [varchar](8) NULL, [value] [tinyint] NULL, [submitted] [smalldatetime] NULL) Where id serves as the primary key. Virtually every request results in a series of insert statements (one per variable submitted), and then we run a select to produce previous responses for the next page (something like this): SELECT t.id, t.variable, t.value FROM results t WITH (NOLOCK) WHERE t.userid = '2111846' AND (t.variable='internat' OR t.variable='veteran' OR t.variable='athlete') AND t.id IN (SELECT MAX(id) AS id FROM results WITH (NOLOCK) WHERE userid = '2111846' AND (t.variable='internat' OR t.variable='veteran' OR t.variable='athlete') GROUP BY variable) Which, in this case, would return the most recent responses for the variables "internat", "veteran", and "athlete" for user 2111846. We have followed the advice of the database tuning tools in indexing the tables, and against our data, this is the best-performing version of the select query that we have been able to come up with. Even so, there seems to be significant performance degradation as the table approaches 1 million records (and we might have about 150x that). We have a fairly-elegant solution in place for sharding the data across multiple tables which has been working quite well, but I am open for any advice about how I might construct a better version of the select query. We use this structure frequently for storing lots of independent data points, and we like the benefits it provides. So the question is, how can I improve the performance of the select query? I assume the nested select statement is a bad idea, but I have yet to find an alternative that performs as well. Thanks in advance. NB: Since we emphasize creating over reading in this case, and since we never update in place, there doesn't seem to be any penalty (and some advantage) for using the NOLOCK directive in this case.

  • ASP.NET/VB/SQL: trying to insert data, getting error "no value given for required parameters"

    - by Sara
    I am pretty sure this is a basic syntax error, I am new at this and basically figuring things out by trial and error...
