  • Oracle: show parameters on error

    - by llappall
    When Oracle logs a parameterized SQL query failing, it shows "?" in place of the parameters, i.e. the query before replacing parameters. For example, "SELECT * FROM table where col like '?'" SQL state [99999]; error code [29902]; ORA-29902: error in executing ODCIIndexStart() routine ORA-20000: Oracle Text error: DRG-50901: text query parser syntax error on line 1, column 48 Is there a way to change logging so it shows the parameter values? The information above is absolutely useless unless I can see what the actual parsing problem was. In general, is there a way to set logs in Oracle to show parameters in parameterized query errors?

  • Advanced Where Statements in Linq to Entity Framework

    - by JimJams
    Hi, I am wanting to create a Where statement within my Linq statement, but have hit a bit of a stumbling block. I would like to split a string value, and then search using each array item in the Where clause. In my normal Sql statement I would simply loop through the string array, and build up there Where clause then either pass this to a stored procedure, or just execute the sql string. But am not sure how to do this with Linq to Entity? ( From o In db.TableName Where o.Field LIKE Stringvalue Select o ).ToList() Hope you can help. Thanks in advance!

  • Nested partial output caching in asp.net mvc 3

    - by Anwar Chandra
    Hi All, I am using Razor view engine in ASP.Net MVC 3 RC 2 this is part of my view city.cshtml (drastically simplified for the sake of simple example) <!-- in city.cshtml --> <div class="list"> @foreach(var product in SQL.GetProducts(Model.City) ) { <div class="product"> <div>@product.Name</div> <div class="category"> @foreach(var category in SQL.GetCategories(product.ID) ) { <a href="@category.Url">@category.Name</a> » } </div> </div> } </div> I want to cache this part of my output using OutputCache attribute. so I created an action ProductList with OutputCache attribute enabled <!-- in city.cshtml --> <div class="list"> @Html.Action("ProductList", new { City = Model.City }) </div> and I created the view in ProductList.cshtml as below <!-- in ProductList.cshtml --> @foreach(var product in Model.Products ) { <div class="product"> <div>@product.Name</div> <div class="category"> @foreach(var category in SQL.GetCategories(product.ID) ) { <a href="@category.Url">@category.Name</a> » } </div> </div> } but I still need to cache the category path output on each product. so I created an action CategoryPath with OutputCache attribute enabled <!-- in ProductList.cshtml --> @foreach(var product in Model.Products ){ <div class="product"> <div>@product.Name</div> <div class="category"> @Html.Action("CategoryPath", new { ProductID = product.ID }) </div> </div> } but apparently this is not allowed. I got this error.. OutputCacheAttribute is not allowed on child actions which are children of an already cached child action. I believe they have a good reason why they need to disallow this. but I really want this kind of nested Output Caching Please, any idea for a workaround?

  • Accessing Textboxes in Repeater Control

    - by CccTrash
    All the ways I can think to do this seem very hackish. What is the right way to do this, or at least most common? I am retrieving a set of images from a LINQ-to-SQL query and databinding it and some other data to a repeater. I need to add a textbox to each item in the repeater that will let the user change the title of each image, very similar to Flickr. How do I access the textboxes in the repeater control and know which image that textbox belongs to? Here is what the repeater control would look like, with a submit button which would update all the image rows in Linq-to-SQL:

  • JPA Entity Manager resource handling

    - by chiragshahkapadia
    Every time I call JPA method its creating entity and binding query. My persistence properties are: <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect"/> <property name="hibernate.cache.provider_class" value="net.sf.ehcache.hibernate.SingletonEhCacheProvider"/> <property name="hibernate.cache.use_second_level_cache" value="true"/> <property name="hibernate.cache.use_query_cache" value="true"/> And I am creating entity manager the way shown below: emf = Persistence.createEntityManagerFactory("pu"); em = emf.createEntityManager(); em = Persistence.createEntityManagerFactory("pu").createEntityManager(); Is there any nice way to manage entity manager resource instead create new every time or any property can set in persistence.

  • My PowerShell functions do not appear to be registered

    - by Frank
    Hi there, I have a script saved in a ps1 file in which I define 2 functions as such: function Invoke-Sql([string]$query) { Invoke-Sqlcmd -ServerInstance $Server -Database $DB -User $User -Password $Password -Query $query } function Get-Queued { Invoke-Sql "Select * From Comment where AwaitsModeration = 1" } In the PowerShell console I then call the ps1 file by typing it in (it's in a folder in the path, and autocompletion works) However, I cannot start using the functions. I am confused, because when I copy / paste the functions into the console, all is fine and they work. I also have a function defined in my profile, and it works. Where am I thinking wrong, why doesn't it work what I'm trying to do?

  • SecurityException when trying to export a java resource

    - by thecoop
    I'm trying to get the source of a java resource stored in an oracle database using this code (connecting as SYSTEM for testing): DECLARE javalob CLOB; BEGIN DBMS_LOB.CREATETEMPORARY(javalob, false); DBMS_JAVA.EXPORT_RESOURCE('RESOURCENAME', 'SCHEMA', javalob); DBMS_OUTPUT.PUT_LINE(javalob); END; But when I try to run it I get this: Java call terminated by uncaught Java exception: java.lang.SecurityException: cannot read <Resource Handle: RESOURCENAME|SCHEMA|301> because SYSTEM does not have execute privilege on it This thing is, I'm not sure how to grant permissions on <Resource Handle: RESOURCENAME|SCHEMA|301>, as this isn't a SQL or PL/SQL object. And why doesn't SYSTEM have access to it anyway?

  • Postgres: clear entire database before re-creating / re-populating from bash script

    - by Hoff
    hi folks, I'm writing a shell script (will become a cronjob) that will: 1: dump my production database 2: import the dump into my development database Between step 1 and 2, I need to clear the development database (drop all tables?). How is this best accomplished from a shell script? So far, it looks like this: #!/bin/bash time=`date '+%Y'-'%m'-'%d'` # 1. export(dump) the current production database pg_dump -U production_db_name > /backup/dir/backup-${time}.sql # missing step: drop all tables from development database so it can be re-populated # 2. load the backup into the development database psql -U development_db_name < backup/dir/backup-${time}.sql Many thanks in advance!

  • ELMAH: Only sending specific exception type via mail

    - by Sir Code-A-Lot
    Hi, I have ELMAH set up for a webapp, logging exceptions to a SQL server. I wish to have ELMAH send me an email too, but only when a specific exception is thrown (ie. MySpecialException). ELMAH must still log all exceptions to SQL server. I know you can do it programmatically in global.asax, but I'd prefer to use web.config. So, how do I restrict ELMAH error mails to filter out everything but a specific exception type, using web.config?

  • Access Edit Mode Values of BindingSource Control

    - by Christopher Edwards
    I have a BindingSource control (http://msdn.microsoft.com/en-us/library/system.windows.forms.bindingsource.aspx) with a datasource of a (single) Linq object. If I change any of the properties of the underlying Linq-to-Sql object then all the other changes on the bound controls on the form are lost. Does anyone now why and how I work around it? I don't want to call EndEdit because this will commit the changes to the underlying object. I think this might be because my underlying object linq-to-sql object does not implement IEditableObject so the potental new values for the object fields are sort of stored in the forms controls. Can anyone either clarify what is going on and/or suggest a work around. Thanks!

  • Cannot execute "LOAD DATA LOCAL INFILE" Mysql query in Rails after a connection reconnection

    - by Ngan
    On Rails 2.3.8 (but I think Rails 3 might have this issue as well, not sure): I get an error when trying to execute a LOAD DATA LOCAL INFILE query after reconnecting to a database. I have a process that parses a file that can potentially take a bit of time. During the parsing, Mysql closes the connection due to timeout. This is fine, I do a ActiveRecord::Base.verify_active_connections! and I get the connection back (I do this in several places through my app). However, running a LOAD DATA LOCAL INFILE statement, I get this error: Mysql::Error: The used command is not allowed with this MySQL version It's not a permission issue, I know that for sure. Check out my test in console: ActiveRecord::Base.connection.execute("LOAD DATA LOCAL INFILE '/tmp/test.infile' INTO TABLE users") [Sat Jan 08 00:09:29 2011] (9990) SQL (1.7ms) LOAD DATA LOCAL INFILE '/tmp/test.infile' INTO TABLE users => nil > ActiveRecord::Base.connection.disconnect! => #<Mysql:0x104c6f890> > ActiveRecord::Base.verify_active_connections!

It's just this one that giving me the error. I even tested this with a fresh rails app. You'll notice that I am able to do the exact same query before the disconnect. Thanks for the help!

  • Correct way to make datasources/resources a deploy-time setting

    - by Draemon
    I have a web-app that requires two settings: A JDBC datasource A string token I desperately want to be able to deploy one .war to various different containers (jetty,tomcat,gf3 minimum) and configure these settings at application level within the container. My code does this: InitialContext ctx = new InitialContext(); Context envCtx = (javax.naming.Context) ctx.lookup("java:comp/env"); token = (String)envCtx.lookup("token"); ds = (DataSource)envCtx.lookup("jdbc/datasource") Let's assume I've used the glassfish management interface to create two jdbc resources: jdbc/test-datasource and jdbc/live-datasource which connect to different copies of the same schema, on different servers, different credentials etc. Say I want to deploy this to glassfish with and point it at the test datasource, I might have this in my sun-web.xml: ... <resource-ref> <res-ref-name>jdbc/datasource</res-ref-name> <jndi-name>jdbc/test-datasource</jndi-name> </resource-ref> ... but sun-web.xml goes inside my war, right? surely there must be a way to do this through the management interface Am I even trying to do the right thing? Do other containers make this any easier? I'd be particularly interested in how jetty 7 handles this since I use it for development. EDIT Tomcat has a reasonable way to do this: Create $TOMCAT_HOME/conf/Catalina/localhost/webapp.xml with: <?xml version="1.0" encoding="UTF-8"?> <Context antiResourceLocking="false" privileged="true"> <!-- String resource --> <Environment name="token" value="value of token" type="java.lang.String" override="false" /> <!-- Linking to a global resource --> <ResourceLink name="jdbc/datasource1" global="jdbc/test" type="javax.sql.DataSource" /> <!-- Derby --> <Resource name="jdbc/datasource2" type="javax.sql.DataSource" auth="Container" driverClassName="org.apache.derby.jdbc.EmbeddedDataSource" url="jdbc:derby:test;create=true" /> <!-- H2 --> <Resource name="jdbc/datasource3" type="javax.sql.DataSource" auth="Container" driverClassName="org.h2.jdbcx.JdbcDataSource" url="jdbc:h2:~/test" username="sa" password="" /> </Context> Note that override="false" means the opposite. It means that this setting can't be overriden by web.xml. I like this approach because the file is part of the container configuration not the war, but it's not part of the global configuration; it's webapp specific. I guess I expect a bit more from glassfish since it is supposed to have a full web admin interface, but I would be happy enough with something equivalent to the above.

  • MySQL query killing my server

    - by Webnet
    Looking at this query there's got to be something bogging it down that I'm not noticing. I ran it for 7 minutes and it only updated 2 rows. //set product count for makes $tru->query->run(array( 'name' => 'get-make-list', 'sql' => 'SELECT id, name FROM vehicle_make', 'connection' => 'core' )); while($tempMake = $tru->query->getArray('get-make-list')) { $tru->query->run(array( 'name' => 'update-product-count', 'sql' => 'UPDATE vehicle_make SET product_count = ( SELECT COUNT(product_id) FROM taxonomy_master WHERE v_id IN ( SELECT id FROM vehicle_catalog WHERE make_id = '.$tempMake['id'].' ) ) WHERE id = '.$tempMake['id'], 'connection' => 'core' )); } I'm sure this query can be optimized to perform better, but I can't think of how to do it. vehicle_make = 45 rows taxonomy_master = 11,223 rows vehicle_catalog = 5,108 rows All tables have appropriate indexes

  • Asp.Net MVC best way to update cached table

    - by Eddy Mishiyev
    There are certain tables that get called often but updated rarely. One of these tables is Departments. So to save DB trips, I think it is ok to cache this table taking into consideration that the table has very small size. However, once you cached it an issue of keeping the table data fresh occurs. So what is the best way to determine that the table is dirty and therefore requires a reload and how that code should be invoked. I look for solution that will be scalable. So updating the cache right after inserting will not work. So if one machine inserted the record all other on network should get notified to reload the cache. I was thinking for calling corresponding web service from T-SQL but don't really like the idea of consuming recourses on sql server. So what are the best practices to resolve this type of problems. Thanks in advance Eddy

  • Problem with datagridvieew in vb.net

    - by user225269
    I'm trying to add a datagridview in vb.net, but it does not allow me to change the connection string or the database that should be imported to connect to it. The only thing that I'm seeing is the previous ms sql database that I connected with datagridview and everytime I click the new connection, the window closes and it leaves me with the datagridview with the previous connection that I have. And its not applicable because, now I want to connect it with mysql. Not ms sql. Its some sort of a cache like feature in vb.net, how do I get rid of it. so that I can add the new connection for mysql? Do I need to reinstall visual studio 2008?

  • How do i keep my DB and lucene in sync?

    - by acidzombie24
    So i can have a transaction in sql. But i am sure its not a good idea to wait in the middle of a transaction for lucene to finish also i am unsure if lucene is permanently saved in the DB until i do something there. Whats the best way to keep my DB and lucene in sync? I am thinking of adding a lucene_queue in my sql db and everytime i make a change i add it into the queue (removing older queue if any) and delete it once it is done. Is this the best way? Also i am unsure how to make lucene permanently keep the changes i made and how frequent i can/should do it.

  • Reading from a oracle temp table in a separate procedure than the one it was populted in

    - by Bob
    I have a 2 stored procedures, the first creates an oracle temp table and the second reads from it. The temp table only has scope for that session. I'm calling the procedures from .Net and the second procedure never returns any results. However if I use the same sprocs and parameters in SQL*Plus it works fine. I've tried creating an Oracle Transaction object and had hoped I'd be able to read the tables in while still using the same transaction - trying to emulate an SQL Plus type of single connection environment. Any ideas what I'm doing wrong??

  • Best architecture for accessing secondary database

    - by fearofawhackplanet
    I'm currently developing an app which will use a Linq to SQL (or possibly EF) data access layer. We already have a database which holds all our Contacts information, but there is currently no API around this. I need to interact with this DB from the new app to retrieve contact details. I can think of two ways I could do this - 1) Develop a suite of web services against the contacts database 2) Write a Linq to SQL (or EF) DAL and API against the contacts database I will probably be developing several further apps in the future which will also need access to the Contacts data. Which would generally be the prefered method? What are the points I need to consider? Am I even asking a sensible question, or am I missing something obvious?

  • NHibernate Named Query Parameter Numbering @p1 @p2 etc

    - by IanT8
    A colleague recently ran into a problem where he was passing in a single date parameter to a named query. In the query, the parameter was being used twice, once in an expression and once in a GROUP BY clause. Much to our surprise, we discovered that NHibernate used two variables and sent the single named parameter in twice, as @p1 and @p2. This behaviour caused SQL to fail the query, with the usual "a column in the select clause is not in the group by clause" (I paraphrase ofcourse). Is this behaviour normal? Can it be changed? Seems to me that if you have a parameter name like :startDate, NHibernate only needs to pass in @p1 no matter how many times you might refer to :startDate in the query. Any comments? The problem was worked around by using another sub-query to overcome the SQL parsing error.

It's working with Oracle 11.2.0.1.0 but not with Oracle 11.2.0.3.0. Just to clarify...

  • Perform Grouping of Resultset in Code

    - by NinjaBomb
    Stackoverflowers, I have a resultset from a SQL query in the form of: Category Column2 Column3 A 2 3.50 A 3 2 B 3 2 B 1 5 ... I need to group the resultset based on the Category column and sum the values for Column2 and Column3. I have to do it in code because I cannot perform the grouping in the SQL query that gets the data due to the complexity of the query (long story). This grouped data will then be displayed in a table. I have it working for specific set of values in the Category column, but I would like a solution that would handle any possible values that appear in the Category column. I know there has to be a straightforward, efficient way to do it but I cannot wrap my head around it right now. How would you accomplish it?

  • How to do a range query

    - by Walter H
    I have a bunch of numbers timestamps that I want to check against a range to see if they match a particular range of dates. Basically like a BETWEEN .. AND .. match in SQL. The obvious data structure would be a B-tree, but while there are a number of B-tree implementations on CPAN, they only seem to implement exact matching. Berkeley DB has the same problem; there are B-tree indices, but no range matching. What would be the simplest way to do this? I don't want to use an SQL database unless I have to. Clarification: I have a lot of these, so I'm looking for an efficient method, not just grep over an array.
