  • Synchronizing an ERWin model with a Visual Studio 2008 GDR 2/2010 db project

    - by Grant Back
    I am looking for options to get our vast collection of DB objects across many DBs into source control (TFS 2010). Once we succeed here, we will work toward generating our alter scripts for a particular DB change via TFS build. The problem is, our data architecture group is responsible for maintaining the DB objects (excluding SPs), and they work within a model centric process, via ERWin. What this means, is that they maintain the DBs via ERWin models, and generate alters from them that are used to release changes. In order to achieve our goal of getting the DB objects (not just the ERWin models) into TFS, I believe the best option is to do this via Visual Studio DB projects. From what I can tell, there is very little urgency for CA to continue supporting an integration between ERWin and Visual Studio, that no longer works as of Visual Studio 2008 DB Ed. GDR. If I have been mislead in this regard, please feel free to set me straight. One potential solution is to: Perform changes in the ERWin model. Take the alter script generated from ERWin, and import the script into the appropriate Visual Studio DB project, updating the objects in the in the DB project Check the changed objects in the DB project into TFS. TFS Build executes to generate the alter scripts that will be used to push the changes through our release process. My question is, is this solution viable, or are there any other options?

  • Oracle custom sort

    - by Carter
    The query... select distinct name from myTable returns a bunch of values that start with the following character sequences... ADL* FG* FH* LAS* TWUP* Where '*' is the remainder of the string. I want to do an order by that sorts in the following manner... ADL* LAS* TWUP* FG* FH* But then I also want to sort within each name in the standard order by fashion. So, an example, if I have the following values LAS-21A TWUP-1 FG999 FH3 ADL99999 ADL88888 ADL77777 LAS2 I want it to be sorted like this... ADL77777 ADL88888 ADL99999 LAS2 TWUP-1 FG999 FH3 I initially thought I could accomplish this vias doing an order by decode(blah) with some like trickery inside of the decode but I've been unable to accomplish it. Any insights?

  • Atomic INSERT/SELECT in HSQLDB

    - by PartlyCloudy
    Hello, I have the following hsqldb table, in which I map UUIDs to auto incremented IDs: SHORT_ID (BIG INT, PK, auto incremented) | UUID (VARCHAR, unique) Create command: CREATE TABLE table (SHORT_ID BIGINT GENERATED BY DEFAULT AS IDENTITY PRIMARY KEY, UUID VARCHAR(36) UNIQUE) In order to add new pairs concurrently, I want to use the atomic MERGE INTO statement. So my (prepared) statement looks like this: MERGE INTO table USING (VALUES(CAST(? AS VARCHAR(36)))) AS v(x) ON ID_MAP.UUID = v.x WHEN NOT MATCHED THEN INSERT VALUES v.x When I execute the statement (setting the placeholder correctly), I always get a Caused by: org.hsqldb.HsqlException: row column count mismatch Could you please give me a hint, what is going wrong here? Thanks in advance.

  • T-SQL Right Joins to ALL Entries inc Selected Column

    - by Pace
    Hi Experts, I have the following Query which produces the output below; SELECT TBLUSERS.USERID, TBLUSERS.ADusername, TBLACCESSLEVELS.ACCESSLEVELID, TBLACCESSLEVELS.AccessLevelName FROM TBLACCESSLEVELS INNER JOIN TBLACCESSRIGHTS ON TBLACCESSLEVELS.ACCESSLEVELID = TBLACCESSRIGHTS.ACCESSLEVELID INNER JOIN TBLUSERS ON TBLACCESSRIGHTS.USERID = TBLUSERS.USERID The output is this; 29 administrator 1 AllUsers 29 administrator 2 JobQueue 29 administrator 3 Telephone Directory Admin 29 administrator 4 Jobqueueadmin 29 administrator 5 UserAdmin 29 administrator 6 Product System 27 alan 1 AllUsers 97 andy 1 AllUsers 26 barry 1 AllUsers 26 barry 2 JobQueue 26 barry 3 Telephone Directory Admin 26 barry 4 Jobqueueadmin 26 barry 5 UserAdmin 26 barry 6 Product System 26 barry 7 Newseditor 26 barry 8 GreetingBoard What I would like to do is modify the query so I get all Access Levels regardless of weather there is an entry for that user. What I would also like to do is some sort of exist case so that I get output like the following; 29 administrator 1 AllUsers True 29 administrator 2 JobQueue True 29 administrator 3 Telephone Directory Admin True 29 administrator 4 Jobqueueadmin True 29 administrator 5 UserAdmin True 29 administrator 6 Product System True 29 administrator 7 Newseditor False 29 administrator 8 GreetingBoard False 27 alan 1 AllUsers True 27 alan 2 JobQueue False 27 alan 3 Telephone Directory Admin False 27 alan 4 Jobqueueadmin False 27 alan 5 UserAdmin False 27 alan 6 Product System False 27 alan 7 Newseditor False 27 alan 8 GreetingBoard False 97 andy 1 AllUsers True 97 andy 2 JobQueue False 97 andy 3 Telephone Directory Admin False 97 andy 4 Jobqueueadmin False 97 andy 5 UserAdmin False 97 andy 6 Product System False 97 andy 7 Newseditor False 97 andy 8 GreetingBoard False 26 Barry 1 AllUsers True 26 Barry 2 JobQueue True 26 Barry 3 Telephone Directory Admin True 26 Barry 4 Jobqueueadmin True 26 Barry 5 UserAdmin True 26 Barry 6 Product System True 26 Barry 7 Newseditor True 26 Barry 8 GreetingBoard True ......................................... So the rules are ALWAYS show ALL Entries for ACCESSLEVELS and where EXISTS in ACCESSRIGHTS produce a true / false to show this. I hope this makes sense and hopefully you dont need the table definitions as everything I need to work with is in the original Query. I just need a way of manipulating it slightly and getting the join in the right place. Thank you. Pace

  • MySQL stored procedure, handling multiple cursors and query results

    - by Tirithen
    How can I use two cursors in the same routine? If I remove the second cursor declaration and fetch loop everthing works fine. The routine is used for adding a friend in my webapp. It takes the id of the current user and the email of the friend we want to add as a friend, then it checks if the email has a corresponding user id and if no friend relation exists it will create one. Any other routine solution than this one would be great as well. DROP PROCEDURE IF EXISTS addNewFriend; DELIMITER // CREATE PROCEDURE addNewFriend(IN inUserId INT UNSIGNED, IN inFriendEmail VARCHAR(80)) BEGIN DECLARE tempFriendId INT UNSIGNED DEFAULT 0; DECLARE tempId INT UNSIGNED DEFAULT 0; DECLARE done INT DEFAULT 0; DECLARE cur CURSOR FOR SELECT id FROM users WHERE email = inFriendEmail; DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = 1; OPEN cur; REPEAT FETCH cur INTO tempFriendId; UNTIL done = 1 END REPEAT; CLOSE cur; DECLARE cur CURSOR FOR SELECT user_id FROM users_friends WHERE user_id = tempFriendId OR friend_id = tempFriendId; DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = 1; OPEN cur; REPEAT FETCH cur INTO tempId; UNTIL done = 1 END REPEAT; CLOSE cur; IF tempFriendId != 0 AND tempId != 0 THEN INSERT INTO users_friends (user_id, friend_id) VALUES(inUserId, tempFriendId); END IF; SELECT tempFriendId as friendId; END // DELIMITER ;

  • C# SqlDataReader = null?

    - by tom
    myConnection.Open(); SqlDataReader myreader; myreader = SqlCom.ExecuteReader(); int id = -1; ErrorBox.InnerHtml = "Username:" + sUserName + ":" + sPassword + ":<br/>"; while (myreader.HasRows) { id = (int)myreader["id"]; String sUser = (String)myreader["Username"]; String sPass = (String)myreader["Password"]; ErrorBox.InnerHtml += "UserId is <b>" + id + "</b> " + sUser + ":" + sPass + ":<br >"; Session["LoginID"] = id; Server.Transfer(ReturnPage); } if (id == -1) { ErrorBox.InnerHtml = "Incorrect Password"; } myConnection.Close(); I added a breakpoint at myreader = SqlCom.ExecuteReader(); and it keeps returning myreader as null and HasRows = False, but it does have rows. So, it keeps validating my login as incorrect since id = -1, Help?

  • SOAP call with query on result (SSRS, Sharepoint)

    - by Erik404
    Hi! I created a report in VS using a shared data source which is connected to a sharepoint list. In the report I created a dataset with a SOAP call to the data source so I get the result from the sharepoint list in a table. this is the soap call <Query> <SoapAction>http://schemas.microsoft.com/sharepoint/soap/GetListItems</SoapAction> <Method Namespace="http://schemas.microsoft.com/sharepoint/soap/" Name="GetListItems"> <Parameters> <Parameter Name="listName"> <DefaultValue>{BD8D39B7-FA0B-491D-AC6F-EC9B0978E0CE}</DefaultValue> </Parameter> <Parameter Name="viewName"> <DefaultValue>{E2168426-804F-4836-9BE4-DC5F8D08A54F}</DefaultValue> </Parameter> <Parameter Name="rowLimit"> <DefaultValue>9999</DefaultValue> </Parameter> </Parameters> </Method> <ElementPath IgnoreNamespaces="True">*</ElementPath> </Query> THis works fine, I have a result which I can show in a report, but I want to have the ability to select a parameter to filter the result on. I have created a parameter and when I preview the Report I see the dropdownbox which I can use to make a selection from the Title field, when I do this it still shows the first record, obviously it doens't work yet (DUH!) because I need to create a query somewhere, But! I have no idea where, I tried to include <Where> <Eq> <FieldRef Name="ows_Title" /> <Value Type="Text">testValue</Value> </Eq> </Where> in the the soap request but it didn't worked... I've searched teh intarwebz but couldn't find any simliar problems... kinda stuck now...any thoughts on this? EDIT Here's the query I used according to the blogpost Alex Angas linked. <Query> <SoapAction>http://schemas.microsoft.com/sharepoint/soap/GetListItems</SoapAction> <Method Namespace="http://schemas.microsoft.com/sharepoint/soap/" Name="GetListItems"> <queryOptions></queryOptions> <query><Query> <Where> <Eq> <FieldRef Name="ows_Title"/> <Value Type="Text">someValue</Value> </Eq> </Where> </Query></query> <Parameters> <Parameter Name="listName"> <DefaultValue>{BD8D39B7-FA0B-491D-AC6F-EC9B0978E0CE}</DefaultValue> </Parameter> <Parameter Name="viewName"> <DefaultValue>{E2168426-804F-4836-9BE4-DC5F8D08A54F}</DefaultValue> </Parameter> <Parameter Name="rowLimit"> <DefaultValue>9999</DefaultValue> </Parameter> </Parameters> </Method> <ElementPath IgnoreNamespaces="True">*</ElementPath> </Query> I tried to put the new query statement in every possible way in the existing, but it doesn't work at all, I do not get an error though so the code is valid, but I still get an unfiltered list as return... pulling my hair out here!

  • How to avoid using duplicate savepoint names in nested transactions in nested stored procs?

    - by Gary McGill
    I have a pattern that I almost always follow, where if I need to wrap up an operation in a transaction, I do this: BEGIN TRANSACTION SAVE TRANSACTION TX -- Stuff IF @error <> 0 ROLLBACK TRANSACTION TX COMMIT TRANSACTION That's served me well enough in the past, but after years of using this pattern (and copy-pasting the above code), I've suddenly discovered a flaw which comes as a complete shock. Quite often, I'll have a stored procedure calling other stored procedures, all of which use this same pattern. What I've discovered (to my cost) is that because I'm using the same savepoint name everywhere, I can get into a situation where my outer transaction is partially committed - precisely the opposite of the atomicity that I'm trying to achieve. I've put together an example that exhibits the problem. This is a single batch (no nested stored procs), and so it looks a little odd in that you probably wouldn't use the same savepoint name twice in the same batch, but my real-world scenario would be too confusing to post. CREATE TABLE Test (test INTEGER NOT NULL) BEGIN TRAN SAVE TRAN TX BEGIN TRAN SAVE TRAN TX INSERT INTO Test(test) VALUES (1) COMMIT TRAN TX BEGIN TRAN SAVE TRAN TX INSERT INTO Test(test) VALUES (2) COMMIT TRAN TX DELETE FROM Test ROLLBACK TRAN TX COMMIT TRAN TX SELECT * FROM Test DROP TABLE Test When I execute this, it lists one record, with value "1". In other words, even though I rolled back my outer transaction, a record was added to the table. What's happening is that the ROLLBACK TRANSACTION TX at the outer level is rolling back as far as the last SAVE TRANSACTION TX at the inner level. Now that I write this all out, I can see the logic behind it: the server is looking back through the log file, treating it as a linear stream of transactions; it doesn't understand the nesting/hierarchy implied by either the nesting of the transactions (or, in my real-world scenario, by the calls to other stored procedures). So, clearly, I need to start using unique savepoint names instead of blindly using "TX" everywhere. But - and this is where I finally get to the point - is there a way to do this in a copy-pastable way so that I can still use the same code everywhere? Can I auto-generate the savepoint name on the fly somehow? Is there a convention or best-practice for doing this sort of thing? It's not exactly hard to come up with a unique name every time you start a transaction (could base it off the SP name, or somesuch), but I do worry that eventually there would be a conflict - and you wouldn't know about it because rather than causing an error it just silently destroys your data... :-(

  • Cassandra/HBase or just MySQL: Potential problems doing the next thing

    - by alexeypro
    Say I have "user". It's the key. And I need to keep "user count". I am planning to have record with key "user" and value "0" to "9999+ ;-)" (as many as I'll have). What problems I will drive in if I use Cassandra, HBase or MySQL for that? Say, I have thousand of new updates to this "user" key, where I need to increment the value. Am I in trouble? Locked for writes? Any other way of doing that? Why this is done -- there will be a lot of "user"-like keys. Different other cases. But the idea is the same. Why keep it this way -- because I'll have more reads, so I can always get "counted value" very fast.

  • How to optimize this MySQL query

    - by James Simpson
    This query was working fine when the database was small, but now that there are millions of rows in the database, I am realizing I should have looked at optimizing this earlier. It is looking at over 600,000 rows and is Using where; Using temporary; Using filesort (which leads to an execution time of 5-10 seconds). It is using an index on the field 'battle_type.' SELECT username, SUM( outcome ) AS wins, COUNT( * ) - SUM( outcome ) AS losses FROM tblBattleHistory WHERE battle_type = '0' && outcome < '2' GROUP BY username ORDER BY wins DESC , losses ASC , username ASC LIMIT 0 , 50

  • LINQ error when deployed - Security Exception - cannot create DataContext

  • relational data from xml

    - by Beta033
    Our problem is this, we have a relational database to store objects in tables. As any relational database could, several of these tables have multiple foreign keys pointing to other tables (all pretty normal stuff) We've been trying to identify a solution to allow export of this relational data, ideally, only 1 of the objects in the model, to some sort of file (xml, text, ??). So it wouldn't be simple enough to just export 1 table as data stored in other tables would contribute to the complete model of the object. Something like the following picture: Toward this, i've written a routine to export the structure by following the foreign key paths which exports something similar to the following. <Tables> <TableA PK="1", val1, val2, val3> <TableC PK="1", FK_A="1", Val1, val2, val3> <TableC PK="2", FK_A="1", val1, val2, val3> <TableB PK="1", FK_A="1", FK_C="1", val1, val2, val3> <TableB PK="2", FK_A="1", FK_C="2", val1, val2, val3> <TableD PK="1", FK_B="1", FK_C="1", val1> <TableD PK="2", FK_B="2", FK_C="1", val1> </Tables> However, given this structure, it cannot be placed into a heirarchial format (ie D2 is a child of C1 and B2; and B2 is a child of C2) Which in turn, makes my life very difficult when trying to identify a methodology to reimport (and reKey) these objects. Has anybody done anything like this? how do you do it? are there tools or documentation on how this is best accomplished? Thanks for your help.

  • SSIS Intermittent variable error: The system cannot find the file specified

    - by Ben
    Our SSIS pacakges a structured as one Control package and many child packages (about 30) that are invoked from the control package. The child packages are invoked with Execute Package Task. There is one Execute Package Task per child package. Each Execute Package Task uses File Connection Manager to specify path to the child package dtsx file. There is one File Connection Manager per child package. Each File Connection Manager has an expression defined for ConnectionString property. This expression looks like this: @[Template::FolderPackages]+"MyPackage.dtsx", the file name is different for each package. The variable (FolderPackages) is specified in the SSIS package configuration file. The error that is generated during run time is "Error 0x80070002 while loading package file "MyPackage.dtsx". The system cannot find the file specified." The package that fails is different from run to run and sometimes no packages fail at all. This is when run on exactly the same environment/data etc. I ran FileMon during this error and found out that when the error happens SSIS tries to read the dtsx file from a wrong place, namely from system32. I checked that this is identical to what would happen if @[Template::FolderPackages] variable were empty, but because the very same variable is used for every child package and works for some but doesn't work sometimes for others, I have no expalnation to this fact. Anything obvious, or time to raise a support call with Microsoft?

  • TSQL Query: Escaping Special Characters

    - by Abs
    Hello all, I am trying to escape special characters in a TSQL query. I have done this before: SELECT columns FROM table WHERE column LIKE '%\%%' ESCAPE '\' And it has worked. Now I have tried to do this now: UPDATE match SET rule_name='31' ESCAPE '\' But it has failed. I know none of the vlaues have a \ but it should still work. I am guessing its because it needs a LIKE statement but how else can I escape characters that I am adding to a database? In addition, does anyone have a link to all the special characters that should be escaped, I couldn't find any documentation on this! Thanks all for any help

  • Primary Key Identity Value Increments On Unique Key Constraint Violation

    - by Jed
    I have a SqlServer 2008 table which has a Primary Key (IsIdentity=Yes) and three other fields that make up a Unique Key constraint. In addition I have a store procedure that inserts a record into the table and I call the sproc via C# using a SqlConnection object. The C# sproc call works fine, however I have noticed interesting results when the C# sproc call violates the Unique Key constraint.... When the sproc call violates the Unique Key constraint, a SqlException is thrown - which is no surprise and cool. However, I notice that the next record that is successfully added to the table has a PK value that is not exactly one more than the previous record - For example: Say the table has five records where the PK values are 1,2,3,4, and 5. The sproc attempts to insert a sixth record, but the Unique Key constraint is violated and, so, the sixth record is not inserted. Then the sproc attempts to insert another record and this time it is successful. - This new record is given a PK value of 7 instead of 6. Is this normal behavior? If so, can you give me a reason why this is so? (If a record fails to insert, why is the PK index incremented?) If this is not normal behavior, can you give me any hints as to why I am seeing these symptoms?

  • SQL Server, temporary tables with truncate vs table variable with delete

    - by Richard
    I have a stored procedure inside which I create a temporary table that typically contains between 1 and 10 rows. This table is truncated and filled many times during the stored procedure. It is truncated as this is faster than delete. Do I get any performance increase by replacing this temporary table with a table variable when I suffer a penalty for using delete (truncate does not work on table variables) Whilst table variables are mainly in memory and are generally faster than temp tables do I loose any benefit by having to delete rather than truncate?
